With massive GM engine recall and Tundra issues, is the 0W-20 a good oil?

I'm not changing the oil viscosity in my Toyota just because GM engines suck

Are 2016-2023 3G Tacomas and 2010-2024 5G 4Runners reliable in your book? Cause they also use 0W20

I've been running 5w30 since probable 3k miles on the truck. The motor is a little quieter and smoother as you would expect. I have a hard time believing that a warranty would be denied over it. I am taking the chance. I also plan on keeping this truck for 2-300k miles, so I think the little bit of added protection could help in the higher miles. I'm pretty sure that if CAFE standards or whatever is driving the mpg regs, we would not be playing with 0w20 or thinner oils. Are they adequate in most engines? absolutely. Do I feel better going up one grade? you betcha. Would the manufacturers be pushing thin oils if not driven by mpg standards? I doubt it.

I wouldn’t deviate from what was spec’d in any engine with VVT. If you want to be proactive, change the recommended oil more often.

Well... this was just published from the Car Care Nut.

I know it is just a single data point, but I ran 0W-20 in my Tundra for 14 years without any oiling issues at all.

idk...I have always used the OEM recommended oil with zero issues

Same here, and I live in New Mexico, pretty hot in summer.

This is also my experience. I have three Toyota engines in my stable (actually 4, but my pushrod 2FE doesn't count). The recommended oil for my 1998 3RZ is 5W30, the 1AR in my 2012 Venza is 0W20, and of course the T24A in the Tacoma with 0W20.

My Venza rattles on 0W20, especially on start-up. The rattle is a known VVTI issue with a TSB. Moving up to 5W30 partially solved this issue and the engine is less noisy overall. I've noticed the same with the Tacoma. It's not as noisy with the 5W30. Personally, I don't think I'm hurting anything running the thicker oil.

Your oil preference is about as personal as underwear. Come to your own conclusions, and run what you want.

yep. over nine years and 107k miles on my ‘17 3rd gen with the recommended and all’s good.

How often should I change my oil?

lmmfao...

Are these engines really that delicate and sensitive that changing from a 20wt oil to a 30wt oil will cause it to blow up? Like come on already! Anyone who thinks this will happen is clearly delusional. Go touch grass.

Anyone worried about viscosity should be doing regular UOAs. Just remember that the 2.4T runs a variable oil-pressure system and it is designed around thin oil. If heat breakdown is your concern, try 0W-30. And yeah, 5W-30 is used in Europe, so you’re fine there too.

Heat breakdown isn’t the concern here…it’s legitimately oil dilution via fuel, and the resulting “shearing” down of viscosity grade, ultimately resulting in increased engine wear. And yes, oil dilution is proven to be an issue with this engine when operated in cold climates. Speaking for myself and my operating conditions…0w20 simply cannot be trusted.
