Thank you everyone for your comments. A number of people have asked for a data as a backup - but you have to remember that when it comes to predicting the durability of engines, the best way to do that is to take the engine apart. You will then clearly see the residue of the oil, condition of the inner components etc, and often times the condition of the engine itself does not correlate with the condition of the engine oil. So it is very deceiving - and dangerous - to assume that the engine is in good condition due to the good condition of the oil (through data and analysis). People like AMD from Car Care Nut, myself as an automotive engineer, and Mr. Takumi Kurosawa (Nissan GT-R engine leader) have all taken hundreds of engines apart and correlated the condition to the frequency and type of engine oil used. That's the best type of "data" and most accurate way to predict the engine condition (you can see it). Because I have taken apart hundreds and hundreds of automotive components apart, I know exactly what needs to be done to take care of automobile components and parts (not just engine), and my recommendations are based on these experiences. My two good friends AMD and Mr. Kurosawa will back me and support me as they have the same insights and ideas as in this video. I hope this helps you understand how I came up with my recommendations. At the end of the day, you are free to decide what to do based on your own experience and knowledge. I am simply sharing my insights based on 35 years of working with cars inside and out.

Criteria A - Maximum Longevity (10 - 20 years) - 400,000 to 800,000 kms - or even longer. Change oil every 3,000 miles / 5,000 kms (6 months or earlier) Criteria B - Good Longevity (4 - 10 years) 160,000 to 400,000 kms Change oil every 5,000 miles / 8,000 kms or once a year or earlier - whichever comes first. Criteria C - Minimum Frequency (1 - 4 years) 40,000 - 160,000 kms People leasing or financing - who don't value longevity are recommended to follow the interval in their owners manual. Oil is able to keep its lubrication properties for a very long time. However, oil does get dirty and air and gas contaminants do get into the mixture Hence, why time is just as important as distance. I have huge respect for David, AMD from The Car Care Nut Channel and every mechanic who offers sensible advice. I live in Alberta, Canada and drive a Corolla Hybrid. I use a 4 month oil change interval. January - April May - August September - December I drive less than 15,000 kms annually (suburban 60% & highway 40%) Car has been rust-proofed and PPF added because the Alberta government has a ton of salt and sand added to the roads during the long winter months. The same applies to much of Canada. Toyota Corolla Sedan owners are advised to use 0W-16 oil... The weight is written on the oil cap. Criteria A - Phenomenal owners Criteria B - Fantastic owners Criteria C - Are not bothered about the longevity of their vehicles and less likely to maintain them - Zero respect. Thank you David & The Car Care Nut

Thanks for this comment. There is something that has been bugging me with oil analysis. Like it might be missing some important things? I feel like we tripled the oil change mileage and at the same time added direct injection, turbos, and some questionable fuel with ethanol. I don't think oil capacity has increased much at all. Which all points to it being harder on the engine oil. I also feel that longer drain intervals will lead to more oil leaks but I have no proof of this. A major oil leak is almost as bad as an engine failure if it costs me $7000 to take the engine out and fix it. It just seems too easy to keep doing 5K oil changes instead of that. Thanks!

@@garymaclean6903 Thank you for your comments, I appreciate you've taken the time to reply. However, you've completely misunderstood what I was trying to say. Yes the oil analysis will tell you the exact condition of the oil itself. However, at 3,000 or 5,000 miles, the oil would still be in good condition and would not have deteriorated enough to be a concern. Testing at these mileage would be waste of time. I would say beyond 7,000 miles the actual condition of the oil would matter. But unlike long-haul truck industry, you would not normally need to test the oil to see how long "you can keep driving" while keeping the same oil. You would normally try not to extend that much just to save a few quarts of oil - this might matter to long haul trucks but in automobiles, the cost of oil is cheap enough that you can change them out while the oil is still in good condition. I have taken engine apart, tested oil, tested various parts, and examined data to know this as a fact. You cannot compare long haul truck industry methods to modern consumer oriented automobiles where you don't need to prolong the oil until the oil is almost end of life.

"Extracting" a few thousand miles won't save you much money, but over time, could affect. your engine. The engine oil analysis will only tell you one dimension of what protects an engine. There could be debris and contaminants floating within the engine that may now be caught by the "sampling" tests.

Great advice on how to make an engine last. Personally I don't care if I'm planning on keeping my vehicles basically forever or if I'm going to get rid of them every 50,000 miles. I'm going to treat every vehicle the same. I want to know when someone purchases something I bought new, broke in, and maintained, that they're going to buy something that could last another quarter million miles. I don't care if that person is a grandkid or some stranger I'll never meet. It's just the right thing to do.

@@JHKCF Basically every driver have different driving conditions which does not fit the ideal manufacturer oil change interval. You may have short trips like driving to work every day for 5 minutes which does not allow the engine to fully warm up. You may be a driver that does mostly city driving and that effects the engine oil. On the other hand you drive mainly highway driving which is good for the car. Then weather plays a part in which dusty and extreme freezing condition or very hot desert condition will effect engine oil wear. So the 10,000 mile oil change the manufacturer recommended is not ideal for that driver that drives short trips mainly in the city. On the other hand the driver that drives mainly highway for an hour every day the 10,000 mile oil change in mostly warm weather above freezing would be good for the engine.

In a previous job I got to visit the lab where a very well known brand of oil was formulated and tested. The chief engineer told me that if I wanted to have virtually zero engine wear I should take the recommended service interval and halve it. So 12k miles becomes 6k and so on. I followed his advice and my last car was 19 years old when it had to be scrapped due to rust. But the engine still ran like a sewing machine.

On top of that it's simply about risk, there's no 100% guarantee of issues (or lack of issues) regardless of how often you change oil, or when those issues will arise.

Engine longevity & wear/tear (as well as carbon sludge accumulation) also depends on how the vehicle was driven, whether top tier fuel was used & even whether or not engine uses at least some partial port-injection instead of 100% direct-injection (aka likely carbon sludge magnet). Lots of long, open highway miles, or mostly short trips and/or city-driving stop/go traffic miles can each have a lot of impact on engine health.

The 2.4L used in CR-V is one of the worst Honda engine and every mechanic knows they will burn oil if the owner will go more 6000 miles/10,000 km on oil changes. While Toyota fixed the oil consumption issues in their 2.4L, by updating pistons and rings, Honda did pretty much nothing. I changed/rebuild dozens of those engines, at least 3-4 every year. In fact there's a one waiting for us this month - it will get low mileage engine sourced from Japan, since it cost the same head/valve job and installing new rings. The same goes for automatic transmissions - they hold less fluid and require more frequent ATF changes. 50k km is the norm. My recommendation max 5k miles OCI on synthetic oil. And if you live in southern US, 5W-30 since it boiling temp is usually higher than 5w-20 oils and doesn't get baked as easy in your oil control rings.

except that older cars/engines benefit from MORE frequent oil changes than standard/original. Furthermore, increasingly over past 20 yrs of the lengthened OCI's, mounting evidence has risen of engines becoming damaged before they were expected to. E.g. in toyota or honda engines, not lasting anywhere near as long as other same engines do when oil changed more frequently and closer to original classic intervals of 3-4K if car is daily driver. Out of my dozens of high-caliber mechanics, they also say more frequent is better in most cases, partly bcuz various factors of engine systems in past 25 years, as well as reduced quality of engines vs 35 years ago, warrants more frequent OC's if u want the engine to last the often-possible extremely high mileages or high-years that Honda and Toyota can. It's cheap insurance that's for sure.

The executives go to the engineers and ask what is the MINIMUM oil change distance to get the vehicle *past warranty* - not necessarily what is optimal for an extended life of the vehicle. (In fact, it's in their interests for a car to "fail early" - so you go and buy another one, rather than keep it 25 years!!).

@@charley95sheridan44 I agree, I’m 73 and the only person to change the oil in all my vehicles, even the numerous new vehicles I bought I have never let the dealership give me a free oil change. When I lived in town with a lot of short trips I changed oil and filter at 2k miles and after I moved out in the country I started going to 3k miles. I also use Mobile 1 0w40 European blend oil which has a very good additive package that I prefer, also it’s just under $5.00 per quart when you buy it in the 3 jug carton from Wally World.

These oil topics are very essential. It is also good when opinions are backed up practically and scientifically. If people have good oil change and car maintenance culture overall, the vehicle will have more potential to run longer without causing super expensive repairs due to oil burning issues and end up on the junkyards as a result of it.

A lesson I learned the hard way myself. Changing the oil at HALF the manufacturers recommendation (i.e. twice as often) is still much, MUCH cheaper than a rebuild or new engine - and will typically PREVENT the problems that require a rebuild or new engine. Manufacturers extend the service interval as a sales pitch (looks cheaper and less inconvenient to the buyer), and have NO interest in keeping your car healthy past warranty - if it kept running fine for 25 years, you wouldn't buy another one....

The oil looks dirty at 1,800 miles compared to my Lexus which always looks clean at the 6 month oil change interval. I use Wix XP filters and Mobil One on each vehicle. Neither car has been to a dealer except for warranty work. I do my own oil changes and maintenance, and by the way, I'm 76 years old....still crawling under the cars. 🙂

In the good old days, when cars and oil were both crap, it made sense to change oil and filter often. Cars and oil are both much better now. I bought a new Acura in 2006. Acura said 10,000 miles on conventional oil and 20,000 miles on the filter. I changed synthetic oil and filter every 10,000 miles. I sold it last fall with 223,000 miles on it. Oil analysis was fine. Performance was perfect. I never added a drop of oil. EPA estimate was 27-34 MPG when new, but I was still getting 35-37 MPG. Just how much better off would I be if I changed the oil over three times as often?

You wouldn't be any better off, kudos to you for doing it right. But someone with that same Acura who lives in a very cold climate, makes mostly short trips, drives with a lead food, uses low quality gas and cheap oil & filters, will probably never need to do oil changes because they'll be constantly topping off with fresh oil as their engine burns through it. This is what people don't get and why this debate continues to rage on. How quickly your oil gets contaminated and breaks down is CONDITIONAL. It's not set in stone.

Same here, but these rules of thumb are not vehicle, driving or environment specific. Certain cars will do fine with 10,000 oil changes if you live in the right area and drive lets say 50 miles to work each way. I have an Acura myself with around 150k miles on it and it still runs like new, and I change the oil every 10k miles with full synthetic oil. But, that car was driven for hundreds of miles at a time on the highway, and it was in a relatively mild climate. If it was used for a lot of local short trips, the oil change interval would be much better at 5k miles...

At 25k it still has plenty TBN and anti wear additives left with minimal wear metals and fuel dilution. It probably would be safe to run 30k intervals but 25k gives me peace of mind.

Yes bypass toilet paper filters. Toilet paper is high quality cellulose. They are trying to hide the fact that they are toilet paper filters. Jackmaster puts a high quality roll of Australian toilet paper in a sock and charges 20 bucks for it. I use Great Value 1000 from Walmart in mine. Most use Scott 1000. People assume toilet paper comes apart in oil. It gets stronger in oil. I started with a Frantz in 1963. Went to the top loaders in the 80s. The Jackmaster needs a firm roll. It has no center tube. They depend on the 1 15/16 core seal at the bottom. All I have used is the classic. Not familiar with the Ultra or the bigger models. I sold Frantz Motor Guard and Gulf Coast filters years ago. Motor Guard only makes compressed air filters now. I think Gulf Coast filters only makes paper towel filters now. When I was selling Frantzs Gulf Coast filters had Frantz 3 stackers all over the Gulf of Mexico. At some point the Frantzs went out of production. We also lost the FAA approved AeroFrantz. In 1963 I was working in a full service Standard station. A Standard oil engineer told me to use a Frantz and Delo. Delo came in 20W and 30W. Couldnt use multi grade in a diesel.

If OEM milage intervals in your manual are based on OEM oil, and that OEM oil is already a full synthetic, I'd argue it's best not to grant any sort of leeway just because you're getting full synthetic. I typically hit the 6 months point long before I hit the milage anyway, so I'm saying that with no skin in the game 🤣 Many owners manuals also list a "standard usage" and "heavy usage" maintenance schedule. With standard being in the 10-12k miles/1yr, and heavy being half of that. And it's very easy to fall into the heavy usage category. Trying to convince my family they fully meet the criteria for heavy usage has been an uphill battle, even though they want to keep their cars to infinity and beyond.

I find remembering to do the oil change is critical. I've got five cars in my "family fleet". The cost of oil for the car is a fraction of the cost of the fuel I put in a car, it doesn't hurt I shop for oil on sale, get good quality oil filters inexpensively and change the oil myself. All that said, I like an interval of 3,333 miles. So, my entire fleet gets oil changes when the odometer ends in 3,333 miles, 6,666 miles and 9,999 (10K) miles. They're all on the same schedule, so I can tell at a glance when I'm due for an oil change on any of the cars I'm responsible for.

2017 RAV4 with mostly highway miles with a road warrior job. Full synthetic, the oil didn't even start getting dirty until 6,000 miles. I added half cup of Seafoam or Marvel Mystery to the crankcase the day before oil change and made sure it was warmed up fully. It is my suspicion that the sludge buildup in/on the piston oil wiper rings are what cause these engines to fail prematurely and start burning oil. As it was mostly highway miles, I usually changed oil at 9k-11k intervals. Call me crazy, but 205,000 miles currently and no oil burning issues. Toyota filters from dealer, oil is not black...maybe dark brown before changing. YMMV but I'm very happy with this vehicle.

David, Excellent video and your time and effort to make it is most appreciated. I need to ask a question. I recently purchased my 11th Honda, in this case, a 2024 Honda CRV Hybrid Touring model. I live in Saskatoon Saskatchewan and get really cold winters and very hot summers. Having purchased the vehicle at the end of October 2023, we had to endure a brutal December. While I park underground in heated parking, I still need to venture outside in those temperatures, park it, and leave it sit for several hours, before restarting to drive it home. The CRV has active grill shutters that assist with getting the engine up to temperature as quickly as possible, in addition to giving me cabin heat, even though the vehicle operates in battery only mode at times. My question is, should I trust the Honda Maintenance minder or go with my gut and change it more often. My concern is that the number of on/off cycles of the hybrid system means that I am more likely to not have the engine up to operating temperature for long enough periods of time to purge the crankcase of unwanted blowby and contaminants. I would really appreciate your thoughts on this question. As others have said, the cheapest engine is really expensive, however the most expensive engine oil is cheap. Thank you.

You are spot on with the recommendations. I drive a 2004 Avalon. purchased brand new. Have changed the oil every 3000 miles or 1 year, whichever comes first. For the last 10 years, it has been short, urban hops to the grocery store. Once or twice a year, highway driving. Car runs like the first day driven, brand new. With the last oil change, I did my first chemical cleaning of the engine for 15 minutes. Preventative maintenance. Toyota no longer offers the Avalon model. So, take the sales tax alone on the 2022 Avalon, over $3000 in my county. That would pay for a lot of oil changes.

Excellent advice. Well explained and makes perfect sense. Oil still must be changed despite advances in synthetic stock and additive packages. I'm glad to see the recent push on KZbin for this as often overworked smaller engines, turbocharged, direct injection etc. have put a lot more demand on oil. Don't trust the manufacturer of your vehicle or the oil company 100% as they are always trying to sell you either their product over another or a replacement vehicle every few years, no such thing as lifetime transmission fluid either. Option 2 will work best for most of us. Nobody advocated for neglecting your vehicle and screwing the next owner, "worst-case" follow the owner's manual recommendations.

I gave up dirty oil and routine oil changes in 1963 with a Frantz oil cleaner and Standard Delo 30W. In those days we changed the filter more often and added more makeup oil. Now I go 6.000 miles between filter changes using Walmart synthetic. I use depth bypass filters on my transmissions. The first filter change and everything is clean. Dont worry about dirty fluid again. Without proper filtration transmission fluid can have more abrasives than motor oil. The old Ford truck has a Gulf Coast filter on it. The 390 engine has a Motor Guard on it. All of my filters use toilet paper except the old Ford diesel tractor that uses a flat head Ford V8 canister filter modified to use a roll of Scott 1000. It has half a roll of Viva towels in it now. No routine draining of good motor oil. The Pontiac has a Australian Jackmaster Classic. A lot of filters that clean oil these days. Not many choices in the 60s. Frantz and Motor Guard is all we had.

I agree it would be better to buy new, instead of lease. But I have been buying off lease CPO Toyota and Lexus because of the lower cost and service history. Although only the manufacture's oil change interval was followed (A) early in it's life, I change oil with (B). Both of these vehicles. 2014 Camry (150K miles), 2008 Lexus ES350 (125K miles) consume very little oil and run great.

I would add a caveat that buying a leased vehicle or or a "program vehicle"/ demo or a used vehicle that is no older than three years can be fine, provided that the Carfax indicated proper oil changes and maintenance. In my life, I have never been stuck with a vehicle that was not cared for properly. Additionally, buying new does NOT guarantee success. As an example, I have experienced a Coyote engine that needed a quart about every 1,500 miles; according to the manufacturer, that usage is normal. I had a second Coyote in a different truck that never used oil during an entire oil change interval. I also had a 305 cu. in. that, after the 12k warranty was up, showed 2 adjacent cylinders with wet spark plugs.

Hi David. You need category D - vehicles equipped with Direct Gas Injection or Turbo or both. The high-pressure blowby degrades the oil to max oil life of 3,000 miles or 4,500 Km regardless of how long you keep your car.

The engine is still running like it was brand new. Hoping our other cars (2016 4 Runner and 2022 CRV) last as long as our 2004 with the push for EV's coming.

And on turbo engines without separate oil pump lubricating the turbo itself it's important to let the engine idle for at least 1 minute before turning off the engine. Giving the turbo time to rev down again before the lubrication is shut down together with the engine shut down. Some cars have separate oil pump for the turbo itself, but not all cars. Something to have in mind. Great video... thanks 👍

Love this topic. Love the categories. Assume we can get a car to 500,000 miles. Assume oil changes are $40 per change. Assume you do it yourself. The differential cost to change it every 3,000 miles vs every 5,000 miles is only $2667 over the 500,000 mile life of that engine. If you drive 25,000 miles a year it will take you 20 years to get to 500,000 miles. It will cost you $11 a month more to change oil at 3,000 vs 5,000 mile intervals. I had a 2017 Ford F150 with the Coyote V8 5.0l engine. I changed oil meticulously trying to maintain 3,000 miles. When I sold it I had a spreadsheet of all maintenance I did on that truck. My mean time between oil changes was 3,400 miles. I had 157,000 miles on that truck. It ran as good as new and I am not exaggerating that. It had the old 6-spd trans and after 75,000 miles I started to suck and fill one quart of trans fluid every two oil changes. This turned out to be very easy to do once I set myself up for a quick “takt time” operation. At 157,000 I sold it and received TOP DOLLAR for the truck of $28,000. It was a basic XLT trim by the way. The guy who bought it now has over 200,000 on it. He is also maintaining it the way I did. We stay in touch and we hope to see that motor at least reach 300,000. I find that to be a very reasonable expectation. My old boss had an F250 with the 6.2l. He drove tons of highway miles. He also loves his truck and maintain 3,000 mile oil change intervals. That truck now has 330,000 miles on it. It is his daily driver. His bird dog owns the back seat and is his constant companion in that truck. David. Thanks for a great video. I hate when people tell me that their book recommends 10k mile oil changes. I try to explain why I shoot for 3,000 but they don’t understand the micro physics of sliding parts separated by an oil film. This I’ll never be able to convince them. That’s ok. I just won’t buy a car from them!

I’m not arguing that changing oil every 3k is a smart practice. Why not every 2k? Wouldn’t that be even better? Why not every 1k? You don’t know that if you changed every 4k that it wouldn’t have still been running as good as new. We live in an economy where some people have to decide whether to spend their money on food or medicine. Luckily I’m not in that category, but if they go every 6k instead of every 3k, that doesn’t make them a bad person, or an uninformed person or even an unwilling person, maybe that’s all they can practically afford to do. Back in the day it was just the standard to go 3k. So was that interval necessary, or did the oil companies want to sell more oil? It reminds me of Proctor and Gamble way back in the day when they had like 90% of the shampoo market but weren’t satisfied. They decided to just change the instructions on the label to say “rinse and repeat”. So now people that followed the instructions used it twice as fast so they could sell more. Was it necessary? The engineer in this video even said, it’s not that the oil loses its ability to lubricate, it’s cause it gets too dirty. So maybe it would be helpful for the car manufacturers to put a color guide in the owners manual, and recommend a certain stage of oil color rather than a set mileage interval. Just a thought.

This all got pretty personal and if I caused any of that I’m apologizing. Oil gets dirty every time the piston hits TDC on combustion. The piston rings are totally awesome by design at how they help control the cylinder pressure but they CANNOT hold it all back. Dirty combustion byproducts come past the piston rings and make the oil get dirty. That “dirt” is carbon byproducts. That carbon is pretty abrasive. That dirty oil may still have lubricity within spec range but it is still dirty. David did say that Toyota race engineers think very short mean time between oil changes is better. I believe this is the reason. Yes it is still “slippery” but it’s also now dirty with carbon blow by and that means it is also now a bit more abrasive. I shoot a lot. I’ve studied carbon deposits in F-Class Benchrest rifles. Carbon deposits left uncleaned are incredibly tough to remove. Especially the “carbon ring” just forward of the bullet right before the lands. Carbon can build up there enough to not only open up shot groups but also produce excessive (dangerous) pressures. I’m wondering is someone out there can technically describe what an oil filter is capable of filtering out of oil? Does an oil filter reduce carbon in the oil from blow by? Or is it only good for larger particles? It would be awesome to understand pressure gradients across an oil filter at 2k, 3k, 4K, 5k up to 10k or even 15k. I would think that when oil pressure gradient picks up to a certain point that’s the time to change oil. I suppose that kind of pressure gauge could be installed. I just changed my F-350 7.3l gas engine oil today. I have 58,000 miles on that truck and my mean time between oil changes is 4,600 miles at this point. I am going to stick to that. Personal choice.

Indeed. Costco has their house brand, Kirkland Signature, which varies between $3.09 and $3.99/qt depending on whether or not it's on sale. This oil is blended and packaged by Highline-Warren (formerly Warren Distribution, in existence since1922) and is listed in the American Petroleum Institute (API) registry as passing all the API and ILSAC requirements, along with the GM Dexos 1 requirements. A kind employee of Blackstone Labs which tests tons of oil samples annually says the results they find with Kirkland show it performs as well as any other good brand and the additive is package it contains is much like the popular brands. HE USES IT because of the good deal. I use it for the same reason! And yes, in my Lexus RX, not an old beater of some kind. The view down the oil filler pipe with a flashlight shows nice and shiney parts with no varnish of any kind at 55,000 miles.

In general I'd agree, but make sure the oil still meets whatever specs are listed in the owners manual. Also, for severe usage such as extreme cold starts, racing, lots of hard driving, heavy towing, particularly hilly terrain, or maybe even lots of heavy traffic, using something a bit better than the cheapest oil you can find may be worth it for the added protection. Same is true IMO for boosted engines. Changing the oil on time is most important, but if ultimate longevity is the goal, I do think there is a time and a place for premium oils.

When I was young and strapped for cash I was told "If you can't afford the oil at least change the filter". Which raises the question: If the oil is capable of longer life as long as it's clean will a fresh filter enable you to run longer (ignoring the mess you might make swapping out filters with a full crankcase)?

I am going to pay out of pocket for oil changes every 5k miles. Also another controversial thing I haven’t heard anyone talk about is that all current “L/Certified” used Lexuses are going to fall out of the certification because of the current airbag recall without resolution. My dealer gave me an equivalent extended warranty through Toyota but it’s not the “same thing” as what I paid for.

People, most service centers at dealerships don’t know anything about oil. Seriously. There was once a time where paying more, a lot more, to have a dealership service your vehicle was worth every cent as they hired skilled mechanics and did top quality honest work. That’s no longer the case, hasn’t been for a long time. Today you still pay through the nose at a dealership for service but they give zero F’s about the quality of work they do, zero. Change your own dang oil. Some things can’t be avoided, recalls etc. but otherwise do as much work as you can on your own vehicle that way you know it’s done with pride and done well. It’s 2024, you can figure out how to do most things on your own.

The whole "normal" versus "severe" service has been controversial since the 1970's when the SAE defined these terms. As I read normal service virtually nobody falls into that criteria which is basically highway driving in good weather. I have always used the following: If the car is not driven much then change the oil every 6 months. Otherwise severe service intervals or no more than 4k for a turbo and 5k for NA. My engines last a long time and do not burn oil. The car I drive actually specifies a 3k OCI with synthetic oil in the owners manual. It is GDI and the oil gets pretty dirty. I also have Fumoto valves installed on all of my cars to make my life easy.

There is no such thing as a full flow filter that cleans oil. All they are supposed to do is keep large engine damaging abrasives from getting to the engine parts.

There are several brands of filters that clean oil. They all have hoses to deal with. I like the ones that use toilet paper or paper towels.
