How frequently do you change?

[@masterofnone1808]

Years ago NYC taxicabs would last for 500,000 miles using conventional oil. The main thing is to change it on time and avoid short trips where the engine never fully warms up. Those NYC cabs were running constantly. Cold starts are the biggest contributor to engine wear.

[@MrNota500]

I have a car that we bought with 20k on it. I have used only conventional oil its whole life, always a good name brand. I change it every 3-5 thousand miles as well as the filter.

You're right... and I don't see the point of a blended oil. If you want longer oil change intervals, or live in an area of temperature extremes just go full synthetic. If that's not so important and you already know you are going to change at more frequent intervals (half the mileage the car maker says is a good guide) why not use the cheaper conventional oil.

[@toomasargel8503]

I think when some body first time his /her life want self cahnge oil is better ask at good service how and find on local dealer what kind oil.

[@josephrisner9596]

Something else worth mentioning with thinner oils is that they flow really well immediately upon start up and can reach the top end of the motor sooner. Most of the engine wear occurs in the first few minutes upon start up, so getting oil where it needs to go as soon as possible it very important

[@ahotdj07]

When starting my car (regardless if the engine is a hard cold or hot), I always wait a minute or two before putting the car in gear.

[@lonniebeal6032]

Ya, too bad that 5w20 loses it ability to do its job over 70f. Find me one link that supports 5w20 at 95f or summer temperature. And no links to owners manuals as they have been falsified.

[@josephrisner9596]

@@lonniebeal6032 It doesn’t lose its ability to do its job. It just becomes diminished. Obviously a higher viscousity heavier weight oil is going to be better at lubricating since it is going to be harder for the moving parts to push out of the way. Every oil has its advantages and disadvantages, no doubt about that.

[@CondoreComputing]

@@lonniebeal6032 70F ? Go look up some viscosity vs temperature graphs that compare 5W20 all the way up to 20W50. Even at 260F 5W20 is in 5 percent max of 5W30, which is about within 10 percent of 5W40, which is within 13 percent or so of 5W50. When your in operating temp 5W20 is only slightly off of 5W30 when it comes to synthetic oils. Actually the hotter you go the closer the variance is, up the temps to 300F and the difference is even smaller. XW20 weight oils have been out since 2002, and started getting used regularly in 2011 or so. If they did not do their job above ambient temperatures of 70F, Toyota, Honda, Chrysler-Fiat and Ford would be having a lot more in warranty issues and updated oil recommendations for older vehicles. Honda and Toyota have been using 0W20 in pretty much all of their 4 and 6 cylinder engines since 2012. 9 years later and there is still no updated oil ratings for those vehicles. This is as silly as everyone arguing 20 years ago about 5W30 being too thin and how all the engines calling for it were going to die of oil related issues, and going against the manufacturer ratings and running 5/10W40 instead. Meanwhile every car our family owns runs 5W30 and have anywhere from 90K to 550K miles with no oil related engine issues whatsoever. Unless you are making modifications that change engine requirements, or are in an unusually severe service tier, your best off using the recommendation in terms of viscosity that the manufacturer built the engine too. Engines are usualy being developed around the newest current oil standards. Or in some cases, a new oil standard is being developed around a new engine that has new requirements.

After seeing actual results from hundreds of teardowns and put backs and retests... Oil is the biggest scam on the market... Once vicosity goes down, it will start evaporating. I leave my oil level at 1/2 and check it monthly, maybe one time a year I may or maynot change a filter.... I probably have drained my oil 5 times in my life... My crappy Dodge Neon lasted 350K before I sold it, with the original filter on it. I have gotten over 200K on every single car I have ever owned.... I never let the oil go lower than 1/2 way point on stick.... Coolant is by far, the most important thing.

You might have also added on the "higher viscosity is better" myth, Scotty, that use of a "thicker" oil than recommended can impede flow throughout the engine, especially where these exotic, by standards of a few generations ago, "twin-cammer" engines with the OHCs and extensive valvetrains. There's a difference between viscosity and lubricity, although they're related. Oil has to GET to the parts in order to lubricate them!

[@davidpowell3347]

Also some of these engines have limited angle rotational joints on their camshafts that can advance and/or retard the actual working part of the camshaft a calibrated amount relative to the driven end of the shaft,this thing is operated by putting oil under pressure into one or another port/chamfer feeding the limited angle actuator and the oil needs to be of very low viscosity to flow fast enough and also the tiniest amount of varnishing could totally mess the thing up

@@0penEyesAndMind51 If the engine has enough wear that a more viscous oil makes a difference, it's a "tired" engine that's in need of a rebuild. But, if it's not going to be driven a lot, subjected to severe conditions, or taken where a breakdown could be disastrous, then 40W oil is CHEAP.

[@0penEyesAndMind51]

@@selfdo actually the theory his a higher viscous or thicker oil is better for old engines. If you are left with only oil on the pistons you want a lower viscosity oil so there is more left on all moving parts

[@callanc3925]

@@0penEyesAndMind51 but the oil recommendation isnt about the heat of the climate. Once the engine is up to temp it doesnt matter how hot it gets outside. What matters is that the oil is able to effectively get between components. This means the recommended viscosity at temp is determined by the tolerancing and design of the engine, whereas the recommended viscosity on cold starts is determined by the climate.

[@grahamfonteyne4792]

I think you would have more influence with people if you didn't call some people "stupid" when they just don't know certain things. Big difference. Stupidity is when you know better but go ahead and do it anyways. Ignorance is when you just don't know about something.

I got High Milage / Synthetic oil, and it seems to work the best out of these three basic engine oil types. No leaks, and no evaporation. And it's viscosity has not degraded. I usually have these problems with other oils.

[@tjlee9901]

i read that even 5w-20 conventional oil is quite stable because it doesnt need so much viscosity modifiers to give the 5-----20 viscosity spread .

[@davidpowell3347]

Some people claim that one brand or another makes their engine run quieter. I think with the spooky low viscosities like 0w-20 or this newfangled 0w-16 it is likely that such oils can only be made stable and evaporation resistant enough to be practical by using synthetic base material.

[@davidpowell3347]

@@tjlee9901 Some viscosity modifiers "viscosity index improvers" (thickeners) as were used in some popular 10w-40 oils during the 1970s and'80s were adjudicated by Tecumseh Engine engineers to have been unsuitable for use in internal combustion engines and I think later GM engineers decided this was true of GM Car and Truck engines--remember the revision made to the 1980 Chevrolet Citation owner's manual

[@bushmaster2936]

Where do you get your oil viscosity tested, and how often? How much oil evaporates over what period of time? Oil leaks aren't caused by oil, they're a result of inferior gaskets or seals or poor installation practices.

[@DeliberateNRandom]

Excellent video! I truly appreciate this! I was looking it up for someone else wanting a generalized response, and learned a few new things myself!

[@marc-oliviercabot3380]

Kind of ambivalent on High Milleage oils.. my old D15B7 Honda loved the thing. A coworkers 2006 Accord with a K24 always ran uber smooth on regular 5w20/5w30 and started doing A LOT of piston slap when the switch was made to High Milleage oil... cleaned the cylinders/pistons and widened some gap somewhere perhaps?

[@slurryz]

Would have like scotty to talk realistically about what oil weights are more useful for old, high mileage engines (regardless of what the manual says)

[@technologyguy101]

Old engines were designed for use with conventional oil. So that what I'd stick to.

[@spaceexplorer6636]

Scotty is not a engineer he’s just a old mechanic. So your owners manual is your guide not someone’s opinion that may be inaccurate.

[@slurryz]

So my 98 Camry with 230,000 miles should still run 5w-30 and not worry about excessive oil getting past the rings?

[@789pokey]

@@slurryz, as long as it's synthetic.

[@njsongwriter]

@@slurryz No reason to change unless the oil consumption has gone up but even then I would try switching brands or switching to high mileage oil before I would play around with changing the viscosity.

Bravo. You answered my question about how often to change my 2021 accord oil filter. Dealer recommend every other oil change but after watching this. I will change every oil change.

[@V8dadmartin]

As a tech I always recommend people to change their oil 1000-2000 miles earlier than what the manufacturer recommends if they drive their cars hard. Last thing you want is worn out dirty oil trying to lubricate a high power motor at its top end power

The number after the "w" is not the summer viscosity. It denotes how the oil behaves at the engine operating temperature. There are other statements by Scotty that are somewhat out-dated.

Dealers " usually " know how to change your oil , but they ll charge a lot . The Quick Oil change places and the Walmarts , Jiff Lubes , etc , usually have inexperienced techs working and they can do more damage than good. Incorrectly tightened/ overtightened drain plugs , Oil filters and not putting the proper amount of oil back in are some of their usual screw ups.

[@Kansas-Paul]

@@jayhockley8841 I took my 2019 ford Ranger to the dealer for its first oil change and they forgot to re connect a sensor on the air intake. I also asked them to check my oil for gasoline contamination because the oil level was high and smelled of fuel. They didn’t so I’m not sure I want to sing the dealer praise song and dance.
