2021 toyota tacoma service intervals

[Timberridge]

Am I gonna have to tell you to take a lap?

Good lord, having worked on Mobil1's F1 oil program in another lifetime I've forgotten more about synthetic oils than you ever knew.
You all just keep on changing your shit whenever you want--it really doesn't matter that much. One day we'll all be rolling on batteries.

Just drive the Jeep Wrangler for a bit.

Changing the oil every 10K is fine, even recommended. The salesman told me this when I was at the dealership, I looked at the wife and said "See? We are saving money already!" and she predictably rolled her eyes.

[AdironRider]

I'm all about Mobil 1 20K extended life.

I like working on cars but fuck doing multiple oil changes a year. I do my Wrangler, Tundra and GX470 in one 3 hour pull every spring and don't think about it again until the next spring.

But I'm just some guy. Toyota's entire brand is built around reliability and they have a much larger data set than any of us to back up 10k intervals on stock oil. They know more about this than you do ultimately.

Anyone got opinions on “lifetime” transmission fluid?

Lifetime is up when your transmission dies.

When I asked about transmission fluid changes at my last service I knew that it was “lifetime” and thought that’s exactly what they meant. Trans fluid can be drained and replaced on my Quattro but the filter is not serviceable. Can’t hurt to swap out with the next oil change.

[ötzi]

My '04 Chevy I wanted to switch over to synthetic trans fluid. Click and Clack said do 3 changes with synthetic and you're good for life. I did it twice, took it in to get the third one done, but forgot to tell the guy synthetic. D'oh! Back to square one I guess.

The trans shop specialists are a PITA. Most "lifetime" oils in the trans IMO are good to about 150-175K assuming you didn't do drag racing. Then if you take it to a trans guy at 150K they give you a song and dance about "we'll do it, but there's no guarantee on our work because you shoulda done it at 100K and the new oil is gonna loosen up gunk so we'd rather not touch it blah blah."

I tell my guy to do it anyways and don't fuck it up. Never had an issue.

Dunno about the Quattro, but on many newer cars the filter is integrated into the pan, either you drop the pan to change it, or buy a new pan with the new filter in it.

I also like to get the diff fluid changed every 60K or so, more often if you are using it offroad a lot. The transfer cases generally run pretty clean and can go longer, I change mine at 80-90K.

Does this land tuco on your disgusting persons list?

Double-check the part about not being serviceable. Several cars I've owned and more I've read about claim lifetime/sealed/non-serviceable but in most cases there are still filters to replace and magnets to clean.

[ill-advised strategy]

An aside:
I have a chinese 79cc predator knock-off on my moped that has no filter and takes like 1/3 of a quart of oil. I put mobile 1 in it when new, then abused it with over-revving it 2x the redline and lots of cold starting and fuel draining through the carb into the oil, way too much load, probably red-hot…etc.

Finally after 6 months of this I was BSing about it with a mechanic at work who was like “those things should be changed every 10 hours” or something like that …so I just did a quicko change right there at work with whatever oil somebody had in his truck.

Right away, in just a few days, that oil looked like milky shit and was foaming enough to trip the low oil sensor.

Back to mobile one, no problems again. I’m a little surprised it’s that much better…but it appears to be.

No, I like tuco. He's just overchanging the oil on his farm truck.

Yeah I did a bit of reading about it when I was doing the rest of my nervous nancy routine when the car went out of warranty. My Audi indy is great and all the dealers in town even send work their way cause it's all former techs (and its an APR shop too), so I trust them when they said non-serviceable and it aligned with my internet doom-scrolling.

If you have a Subaru and have to add oil every other time you get gas, do you ever have to change the oil? Aren't you continually replacing it? Guess you still have to change the filter though.

If you change each part of a boat, one part at a time, is it still the same boat?

This was the stance owners older Harley riders would take as the crankcases always leaked.

On a jet engine the oil is never changed, just topped up. The first time you see a mechanic going up on a scissor lift to add 1 qt of jet oil into the #3 Rolls Royce turbofan on a 747 you're sorta blown away.

[Ted Striker]

And they usually top them up every day.

[BmillsSkier]

It is just consumed by the jet like geese and small birds?

Part of the mechanics job is to inspect the fan blades for knicks and cracks and I guess feathers. Each one is titanium and replaceable at $2000 per. That was the price in the late 90's.

And they usually top them up every day.

One time I got to walk on the wing of a 747 in the hanger with a mechanic. I was awestruck. Just can't appreciate the scale of it sitting on the inside.

[AdironRider]

Kinda like that Johnny Cash song.

Ha. That was my first thought too, but then I thought, wait, it's nothing like that song.

When I worked fire in AK, there was a KC-97 tanked for retardant - 4 radial engines. They pumped oil into that thing from a 55 gallon drum. Probably burned a gallon just firing up.

Yes. It is a law in Lloyd's that the Jane repaired all out of the old until she is entirely new is still the Jane.

FAA doesn't allow detergent, antiwear, or ep additives in oil for reciprocating aviation engines. No ZDDP, or moly or boron or phosphorous. You buy it by viscosity, because it's literally all the same.

A friend took this picture of it starting up on the FBK ramp.

They can only use ashless dispersants in it. Don't use it in your car!

More trivia.
Jet oil comes in metal cans only, whereas aviation piston oil is in plastic. We tried to package jet oil in plastic and the bottles absorbed the oil after 4-6 mos and leaked.

We sold a specially labelled can to the military for their turbine tanks, A-10's etc. The labels were in English and during the Gulf War the locals were stealing it and using it for cooking oil. Unfortunately the additives cause blindness. We had to recall all the cans, and reprint with Arabic warnings not to use it as fry oil.
