Can You Go a Full Year Without Changing Your Oil??

[@stevemiller5350]

I have been changing my oil once a year since 1974. Mobil 1. Excellent results. No engine problems related to lubrication.

[@Android3236]

Just a reminder to everyone, follow your manufacturer’s recommendation on oil change intervals. If it says to change it every 5-6k miles, then do it. If something goes wrong with your engine and you tell them that you put the one year engine oil, you just voided the warranty. Thank you Eric for posting the results, been waiting a whole year for this. Thumbs up. Stay dirty.

[@las3k91]

Mini Cooper S 2008 - user manual says to change oil every 2 years or 15k miles. Not a good idea for me. People stuck to it and then everyone says this engine is a piece of shit, but that's whole another topic.

Yeah then also ask yourself why the European manual for the identical car and engine will have a longer oil change interval.

​@@aciddiver1978Yeah you're just making that up. You're throwing away perfectly good oil then- if you don't believe me just send it in for analysis and they'll tell you it's basically identical to unused oil, it's like $35 all in for a test

[@AudiophileTubes]

I've had my '03 GTI VR6 for 16 years now, and am the original owner. I've been having the dealership change the oil (Castrol Syntec, then lately Castrol Edge 5W-40 fully synthetic) once a year, every summer. The car has about 89,000 miles on it, so I only put about 5,500 miles a year on it, driving mainly local on short trips. I have not had one problem or issue with the engine all these years, and still have the original timing chain. My gut is that once a year is fine running full synthetic of any kind, especially if you don't put more than 7 or 8K miles on the vehicle. I've had no oil leaks as well, and only check the dipstick maybe once or twice a year, as the 24v VR6 does not burn a noticeable amount of oil.

[@mirola73]

Not sponsored by Mobil 1 at all. Did we mention the oil was Mobil 1 ? Mobil 1 !!! (just in case you forgot)

[@dodgecummins6181]

Correct me if I’m wrong but your extended interval caused almost 3 times more wear than the 4,000 mile oil change. Iron and aluminum were much higher. I just found same result when I took my 2022 Tahoe to 12,500 miles. TBN was fine, but wear metals are high.

[@amd.0001]

To be fair though, it's also about 3x the miles so the wear was just the same as usual

[@haqitman]

I get that how dark oil is isn't the entire story on when it should be changed, but according to my calibrated eyeball scanner, that oil you drained out sure looked to be way past its prime. Analysis aside, I wouldn't be entirely comfortable knowing that stuff was sloshing around in my otherwise well-cared-for engine. I think I'll stick to regular Mobil 1 and 4K to 6K change intervals.

It's long gone unfortunately. I shot this video months ago. Also, the testing should tell us all we need to know.

[@wolvenar]

EricTheCarGuy That depends. Does this oil do its thing by somehow helping to trap the particulates in the filter? You would expect several of these contaminants to accumulate much more, so how does it actually deal with them? The filter might be one possibility.

[@Darksyne]

Ehh the filter will look like any other used oil filter and its most likely all black inside. Only abnormal thing you'd see would be sludge or metal fragments and those are highly unlikely unless you have engine damage from neglect which you won't see from Eric's cars ;p

[@MV60]

Would have seen if the filter was so clogged it was just by-passing the oil through the safety valve.

[@DCSPORTSTER]

I’ve actually cut oil filters apart that had 30,000 km on them as long as your engines clean inside there is no dirt in the filter. In my opinion the oil filter will never save your engine if you don’t change oil.

[@dunebasher1971]

Americans really seem to have an obsession with changing the oil every five minutes, for fear that the engine will die if they don't. Here in the UK, it's absolutely standard to change oil and filter once a year at the annual service, and for most people that will be a 10-15k mileage interval. On the available evidence of tens of millions of vehicles over decades, this is absolutely fine and does not hurt the engine in any way. In 30 years of driving I've only ever changed the oil once a year and I've never had any kind of oil-related engine issues in any of my vehicles - and they've all been older high-milers. In fact, when buying a used car in the UK, if you saw from the service history that the oil had been changed every 3-5k miles, you'd probably get suspicious and ask what was wrong with the engine for it to need such frequent changes...

[@SquadleaderMike]

Same here in Germany. Everybody is like "are you fucking nuts?" when I tell them I change my Oil every 15.000 km in my regular 1.8l 140Hp car. Because here it is the most normal thing to change it every 30.000 km. And this is a regular interval. If you use longlife oil, people change it every 2 years or 50.000 / 60.000 km. Thats also how it's written in the service manuals; standard is 1 year / 30.000 km, longlife interval is 2 years / 60.000 km. Also almost every used car over here with 120.000 km seems like it's toasted. Like half of the rubber sealings on the engines are gone bad and it seems like the compression is low.

[@rkan2]

There's no chance that oil will keep it's properties for over a year (2 year long life intervals on new cars, VWs especially) if ran in a real winter climate normally during the winter...

[@dunebasher1971]

120,000km is only 74k miles, and all my previous cars in the UK have been well over 100k miles and on annual oil changes with none of the issues you refer to. My two current cars are at 115k and 100k miles with no signs of damaged seals or low compression, and this is completely as I'd expect from *any* mainstream UK car of that mileage.

[@michaelcapozzi6863]

I just did my own test with this oil as well, I drive a 2012 honda civic si, and I used blackstone labs as my testing ground. I found that I had increased levels of lead, iron, magnesium, boron, sodium, phosphorus, zinc, and aluminum when in comparison to Blackstone's universal averages. The most concerning number for them was the added lead content. In general they suggested that I stick to the 10K interval change of oil and it was my choice to continue using the annual protection oil. I still use annual protection today, but I will be change it at 10K miles instead of 18K which was the length between on my original test. Food for thought.

There was a test of Synth (regular Mobil 1) vs. conventional oil, and they sent samples off to a lab also. The results were that regular Mobil 1 was actually still in good shape at 15K. My point being that if you run regular Mobil 1 you could get very close to the year mark and be fine rather than shelling out the big bucks for the extended life oil. I change every 10K or 6 months - call it good.

I'm a DIY guy so I am under the hood and under the car probably every week. We have realize however that the average car owner doesn't do squat between service. They don't check fluids, inspect tires, suspension and brakes, lube locks or hinges, or even put air in tires (unless visibly flat). Once a year service is inadequate especially in climates that have severe seasons. At a minimum vehicles should be fully serviced at the beginning of summer and then at the beginning of winter and if that means an extra oil change once a year...big deal.

[@xjet]

I had a Honda Accord which I bought from new and ran Mobil 1 oil in it with an annual filter/oil change schedule. When I retired the vehicle (due to rust and crash damage) it had done 303,000 Km (about 180,000 miles). On stripping down the engine, no perceptable lip was found on the bore and there were no other lubrication-related issues observed. The oil-pan and internals were also *very* clean, with no build-up of sludge or carbon. So how is this annual protection stuff any better than that?

[@nickv4073]

Just a tip. If you don't like Walmart oil, which I think is good oil, you can always get a deal on name brand oil, even Mobil One. Just check the web sites and see who is offering a rebate at the time. There is always one or more rebates available at any given time. I once bought a 5 quart jug of Mobil One for $5.00 after rebate.

[@Darksyne]

As long as oils meet modern API and ILSAC GF-5 standards than it's all good, just slightly different additives and as long as you change the oil regularly you should be fine. It is marketing but at the same time there is some truth to that marketing and some oils do have superior cleaning abilities and tougher film strength but you won't notice them in real world driving. Only if performance is a concern.

[@accordinglyryan]

I've been waiting for this video! Despite the testing I still wouldn't feel comfortable going that long on an oil change, but that's more a personal preference I have than anything else. The oil did look pretty dirty too...I wouldn't be fully convinced that this is safe in the long term until a more widespread test is conducted. I change my oil every 5,000 miles personally.

[@CasterTown]

I've always been comfortable running synthetic for 10k between changes. Its an easy way to remember your interval too. Just keep the oil level topped off in between. Then change your oil filter (and check your air filters) each interval also. The oil will be fine.

[@menombakglobalis]

[@lucasornelas6113]

One thing I find funny that nobody has noticed quite yet is that the oil didn't last from start to finish he had to continually add oil so that new fresh oil was being added to the already used oil in the engine . Remember he said it kept burning off . I did the same test with mine and couldn't make it on a whole year without having to add more oil to the engine because of burn off . Most engins will burn off a little oil and you will have to add oil periodically. So it wasn't actually one year old oil change of the engine continually burned off oil then by the end he would have already added a new oil change to the engine . This is why the oil sample he sent in came back good . There was fresh new oil added, it wasn't the same old oil the whole year through otherwise we would have seen different result.

[@insideoutsideupsidedown2218]

Should.have sent a sample in at 3 , 6 and 12 months to compare that way the 1ST sample would have no added oil and the comparison would be more legit

Yes adding fresh oil from the fact that there is engine consumption is a variable. Maybe find an engine where there is less dramatic consumption?

[@MrGoldarr]

I went 9 months on my 2007 Honda Civic Ex that has 123,000 miles in it. I put castrol GTX synthetic blend high mileage oil and an STP extended life oil filter. I was going to go a year, but I went 9 months. I didn’t send it to a lab, but my friend who owns a small shop for 33 years and has been changing oil since he was a kid was impressed. The oil looked and flowed like new. I was also only driving In City for those nine months. I didn’t count the mileage though 🤷‍♂️ it might have been 5000 around there I assume.

[@saltysteel3996]

I use Royal Purple oil and Purolator BOSS filters and still change my oil every 3 thousand miles. Just because an oil may last for 1 year and a filter catches almost everything that flows through it doesn't mean there's no metal wear and contamination in the oil that never goes through the filter. There's oil that passes through bypass valves instead of flowing through the oil filter. There's particles that get caught between rod bearings, crankshaft main bearings, and camshaft bearings. Changing your oil helps to dilute these contaminants out of the engine. Engines running these extended oils such as this Mobil 1 One Year Protection will not last as long as engines being maintained with normal oil change intervals of 3 to 5 thousand miles.

[@stephenmartinez1]

Top quality oil and filter just to dump it at 3k miles? What a disgrace. My 2011 dodge avenger is up to 250k miles. I’m the original owner and have always used either conventional or the low cost synthetic with mid grade filters. The oil life monitor alerts between 4.5-8k miles. That’s what I’ve always gone by, and the engine is still in good shape.

[@bjkarana]

I've used Mobil 1 full synthetic in my 2007 Nissan Altima for the last 6 years along with the Mobil 1 extended performance oil filter. I change my own oil every 6 months and the engine still runs great at 180k miles with no oil leaks and negligible oil consumption. I'd use pretty much any full synthetic oil in the same fashion, but you also need to use a good oil filter that can handle extended intervals. I'd consider the annual Mobil 1, but I live in the desert and worry about the dust building up in the oil that is too small to be filtered out.

[@howtodoitdude1662]

The oil change interval on my current car here in the UK (a 2017 Volvo V40 2.0 D4 twin-turbo diesel) is 18,000 miles or 1 year whichever comes first, so much the same as your van covered with the Mobil1 annual protection. I personally can't figure out why oil changes need to be so frequent in the US, unless you are using poor quality oils or the vehicle is regularly used in a dirty environment. For normal road use, a year should be no problem.

[@TimonNetherlands]

The owner's manual of my Kia Sorento says I must change the oil at an interval of 3.500 miles... This is ridiculous, even more so when you consider it's a diesel. I change oil once a year.

[@SaberusTerras]

Tradition, mostly, when it was plain ol' dinosaur squeezings. Old conventional oils broke down much faster and needed changing every 3000 miles. Also, US uses traffic lights and road designs are not the best for smooth driving at consistent speed. People here are also very chaotic in how they drive*. So we end up with lots of stop and go traffic which is harder on oil than driving long distance at steady RPM. *: I know many countries have bad drivers, but the bad behaviors tend to be consistent. Here, it is true chaos sometimes. I swear some drivers in the US got their license as a prize in their breakfast cereal.

as a builder and an enthusiast for over 5 decades at this point and having had quite some experience over the years i offer this: lubricants have become much better in certain instances but...... if you own a flat tappet engine or an earlier ohc(bucket follower type) engine(pre m.y. 2k on average) i strongly suggest that oil with zinc(zddp) be used. cam wear will be evident otherwise and wiping of the lobes can and often does occur due to use of modern oils that don't contain proper levels of zinc for these engines. the reason zinc levels have been either reduced or eliminated totally is because zinc doesn't play well with catalytic converters. the problem would be multiplied exponentially with some engines now that burn up to a quart in a thousand miles but thanks to some trick metallurgy by some manufacturers the need for zinc has lessened or has been eliminated(roller rockers-etc). before using any type of oil due diligence is required other than just reading in the manual what the mfg recommends. keep in mind that whatever the mfg suggests that you use is based upon an average users requirements and it's NOT ok to run a track day on 0w-whatever weight oil or a turbo installation that drastically increases the bearing surface stresses and heat loading on the oil. understand the requirements of your engine and oil for your driving style and keep an eye on the heat the oil is absorbing from the abuse being handed to it. don't let that oil get too hot and thin out to the point that bearing failure happens. make SURE that on the older engines that the oil contains zinc or sulphur or a combination of both. that chlorine molecule(like that in harley oil and some synthetics)is just not enough by itself. engine or cat failure....what a gamble?! me...i choose to replace cats. it's cheaper. folks with newer beemers that will suffer big end rod bearing failures should heed this warning and NEVER fire off their engines cold and romp on it right away.let the oil warm up...it will take a couple of minutes. second thought...go ahead...ignore the warning. just more work and profit margin for folks like me and my machinist if you do. :-) retired but still building the old & weird ones.... =dok=

They don’t seem to understand that almost any synthetic or blend can get a car to 20,000 miles or one year and can do that for at least 120,000 miles. Some of the labs have results up to 500,000 miles. The 20,000-mile interval doesn’t harm the engine but it does help a lot of things.

[@barrythomas6429]

Another thing to consider..when the vehicle manufacturer nominates an oil change interval.. that change interval is calculated to be while the oil is still proving all necessary protection..NOT when the oil is totally spent. Follow the vehicles oil change interval ..save heaps of $$..and get all the protection you are ever going to need.

[@fixaday]

The oil clearly lasts long enough for one year/20k intervals. From what I see, it has the capability to go even further. However the main concern is significantly more debris suspended in the oil. It's not the oils fault, it's just the accumulation from the extended interval. I think oil filtration should be the top trend for engine lubrication.

[@stuartjohns2779]

I have done once a year oil changes in all my petrol/ lpg vehicles using Amsoil oil and oil filters. 2 of those cars i have owned for over 15 years and both have never given me any trouble. My diesel 4x4 and truck i extend the oil change by 25% and haven't had any trouble either.

[@aymanal_jahwari9148]

I live in Middle east ( OMAN) and most people change the oil every 5000 km and few people do it every 10000 km And i dont know if this is the correct wY to do it or not but i have honda accord 2008, and if i changed the oil after 20000,km then there will be no oil in the engin because the oil decrease by about 1 Liter every 5000,km So it is defficult to exceed 15000 or 20000*km I am nkt sure about this but i think this is related to the high temperature which in mid summar can exceed 60C° and you can add to that there is no rail and the dust id bluking the air filter of the envin and some of it can go inside the engin if not changed gradually Also there is some evidince tbat showing the low quality of the gas I think these factors play major role in engin live

[@nelsblair2667]

I’m 10 months (25,000 miles) into the annual challenge on Pennzoil Platinum from Jiffy Lube. We changed the filter from service champ to wix xp after 7,500 miles. I agree that most or all users should seriously consider the 1-year interval, after the car has reached 70k miles. May every engine reach a million miles!

[@gsmecanica]

What about the oil filter? It might not be suitable for 20k miles...

[@TheRichardF10]

G S The Mobil 1 Annual Protection oil filter is made out of a synthetic blend media which is not suitable for 20,000 miles. A full synthetic media should be used for better filtrations.

[@mikebavoso26]

Very interesting. I have a new Ford with an EcoBoost V6 which produces some ungodly 440 horsepower and over 340 foot pounds of torque. I noticed around 2,100 miles the oil starts to get Gray from its golden yellow. At 2500 it turns black and could this be caused by the blow by of the high pressure from the twin turbos. I try to change the oil before 3000, is this excessive? I was told the oil turns black because it's holding contaminants suspended in the oil, this is what detergent oil does...evidently the Motorcraft filter (Ford requires only original oil filter be used and it is well made inside when I cut one open) is not filtering out these particles and the oil continues to stay black. I shop for Mobile One with the free oil filter option so it's only around $26 to $27 for me to change my own oil, I think this is kind of cheap insurance until I get more information...thanks

[@humansvd3269]

That and oil turns black from going to operating temps. Some oils can resist evaporation better than others. Never heard of oil turning grey. Usually it turns to a golden brown, then brown, then eventually a darker black when it's closer to the end of its life span. I'd highly send a sample to a lab if I were you. Ecoboost engines do turn harder on oil. Quality oil full or syn blend are supposed to last 3k to 5k at a minimum. You shouldn't be running conventional at all with turbos.

[@888johnmac]

does America use different blend petrol/gas & diesel & oil to other countries ?? I'm in the UK & for the last 20 years always changed oil & Filter plus air filter Annually ( I guess average mileage 15-20k miles) no problems.. My works van is a Fiat with advertised 30k service intervals, but in reality the service light usually comes on at 20-25k miles

[@dunebasher1971]

Americans have a bit of a fetish about changing oil every five minutes :) I'd argue that in the UK, it's completely standard to change oil and filter once a year. That's what I've grown up doing, and it's never been a problem.

[@MotorScotti]

dunebasher1971 exactly, same thing in Europe. The factory. recommendations usually are 20-30'000 km / 2 years whatever comes first. So kind of funny to see that it's a huge thing to keep the oil 1 year.

[@moofree]

Europeans have Ultra Low Sulfur gasoline, with a max of 10PPM of Sulfur, which allows for extended oil change intervals. Here in the US, we ostensibly had 10PPM gasoline starting in 2017, but the EPA is still allowing some refineries to sell 50ppm gasoline, so you have no idea how good the gasoline you're putting in your tank is.

[@BEEBEE159]

@888johnmac That's because your piece of shit European cars don't last more than one year. So in your case, you just throw the whole piece of shit car away after a year, no need to change the oil.

I haven't tried the annual protection oil but I've been running regular Mobile One in my Raptor for over 8 years (109,XXX miles).

Thats not very scientific but I'm happy with it.

full synthetic 1 to 3 years on your "weekend car" is not a problem if you don't have extreme climate conditions the oil will still come out still good as new but 25000 km/h is asking for trouble, i would change it after 10.000 km no mater the time passed

My question has always been and will continue to be, what makes 12 months the magic number for engine oil life?

[@InsideOfMyOwnMind]

Eric, are you going to go the full year/20k again or not? Also I may have missed it but did you change the filter in between?

[@marcotomat149]

Of course, the oil is still excellent, but the tiny amounts of metal particles floating in it may contribute to engine tear and wear, so there is a good reason to change it at the recommended intervals or when the oil turns dark in color.

[@zx8401ztv]

That's a great result, you know your vehicle has safe lubrication for another year. One less thing to worry about :-D

[@worldsfinestnegativemind9108]

Engine oil change is not a big deal. Just follow vehicle manufacturers instructions. I have owned two Honda civics and they both lasted more than 200k miles, they were still running good, I just sold them as i got bored.

[@bowez9]

Tin Man I guess people are concerned about the chemistry and not debris. Which tells me filter needs to be changed more often.

Elevated silicon is from not changing air filter frequently enough. Has nothing to do with oil or oil filter.

@@PedalTheGlobe unless you are in a very dusty climate, you would change your air filter every 30k....the dirtier a filter gets, the better it filters. The best filtering your air filter did was ths day it was removed, but a clogged filter doesn't filter anything, dirt will get by somehow some way

@@insideoutsideupsidedown2218 Doesn't matter. The cleaner filter let's the car breath more. You don't want a dirty filter. It's not filtering better.

Cool stuff. I already use Mobil1 synthetic, I love it. But I would never recommend using this oil and changing it yearly.

[@Chris-de2qc]

Why not?

[@ajs622]

I'm not surprised it stood up to it. Mobil 1 is a great oil. I'm sure they did years of testing before releasing this oil. One thing to take note of though before switching to this and going the full change interval. If you are a person who sits idle in traffic for long periods of time, or like to leave the car running with the Ac or heat on when in the store shopping. Don't expect the same one year or 20,000 miles of protection. If the engine is running the oil is breaking down. An hour of idling could be equal to 70 miles of driving or even more since the oil is able to cool better while moving down the road, just idling it may actually get hotter, speeding up wear.

[@Mclovinthedank]

I forgot I was awaiting the results of this, thanks Eric. Not sure about using this in my car...

[@thephantom1492]

One of the hidden issue with this is: it's not just about the oil, but oil filter. The oil filter has been sized to contain the junk that a 1 standard oil change interval would produce. If you go twice or longer, there is a chance that the oil filter will just be unable to have proper flow. This can result in a few things: On partial flow filtration engine, less and less oil would get filtered. On full flow filtrations, a reduced pressure/flow can happend, which reduce the librification and cooling of the parts. Or the filter can be so blocked that the bypass valve open, and let unfiltered oil throught. So the oil can be fine, but the filter can be a big issue. If you use that oil, be sure to also use an high quality filter.

[@dixoncider7256]

Great point.

[@TheRichardF10]

Agree. The filter material on the Mobil 1 Annual Protection oil filters is made of a synthetic blend media. I would only run a full synthetic media oil filter such as Fram Ultra Synthetic which can go 20,000 miles but it has the full synthetic media over Mobil 1's synthetic blend media.

[@TheRichardF10]

Damn, that oil reminded me of the chocolate fountain from Charlie and the Chocolate Factory.

[@65cbtengr]

I can go a full year without changing my oil but i barely drive it and only have 56k miles on my car that i bought new in Nov 07. I've done the oil changes myself every 6k miles with Mobil1 synthetic though since i want that car to last for as long as possible.

[@annieworroll4373]

Worth noting that my driving is probably 85%+ highway, which of course helps to minimize wear and thus would make an extended interval more viable even on regular oil. Heavy city driving could be another story altogether. Also, for reference, I drive a 2000 Pontiac Grand Am GT.

I buy 2 of them because my ram takes 7 quarts. $50 total for oil and $5 for oil filter which equals to $55. No light, no problems, running good. Than my next change would cost me less because I dont need to buy extra oil since I have left over so my next change would run me $30 for oil and filter total. Full synthetic and I change it myself.

I do oil changes on mommas 2000 4runner at about those intervals(1 year or about 15k) but I use a group 4 100% PAO amsoil blend. Which brings me to my next question. Is this mobil one a group 3 hydrocracked "synthetic" or a group 4 synthesized synthetic? What im saying might sound redundant to some but it is not. Her car never burned or leaked a drop of oil and its got a skid pad under it that makes it a pain in the ass to do a change so i decided to switch it over to something that called for less frequent maintenance. When i ran a group 3 synthetic i would notice the oil level drop that you were talking about after a good number of miles. At the time i figured maybe it did burn a little oil over time. Not a big deal, the drop was minimal. A few years later I was educated on the difference between group 3 and 4 base stocks and switched it to amsoil the next time it came up for an oil change. And im sure there are other companies that do a good group 4 synthetic but youve got to research or youll end up putting in a different brand of group 3 "synthetic." Turns out it never did burn a drop. I figured out that it was was volatizing the group 3 base stock oil over the 1 year period. There was a minimal amount of seepage through those old gaskets for the first few thousand miles since i moved it to a group 4 but since then it hasnt leaked burned or volatized a drop. Ill let that seepage slide as a break in period for 20 year old seals and gaskets that had never touched anything but dino oil. I figure your honda is probably the same. Number one its a honda and hondas dont tend to burn oil, and number two its maintained by a mechanic. Probably just volatility.

I am a semi-retired ASE Master Tech. I have been working on cars since 1972.

"Oil is cheap,engines are not". I use nothing but Mobil 1,but ,I follow the oil change monitor on all my cars even though the monitor is for regular oil. The one thing I do that is different is I NEVER let the percentage go below 20%. So, if you want to make the engine run "forever",use Mobil 1 and the "20% rule". My oldest is a 2000 Olds Silhouette van with 230,000 miles run on Mobil 1 and the 20% rule.If I take off the oil fill cap and look inside with a flashlight,I see clean aluminum (the cylinder head).NO SLUDGE.....HAPPY MOTORING.

'Mobil 1' is the oil of choice for Porsche and here in Europe generally has a price to match that elevated status.

Never use 'top quality' branded oils but always get OEM filters etc. Oil consumption is not an issue nor is excessive smoke etc on my little Fiat Seicento (all 54 BHP of it). However, Mobil 1, used in all our Porsche's requires a litre every 5000km which, according to Porsche is completely within 'spec'. This applies to both diesel and petrol engines made by Porsche AFAIK.
