Engine oil OEM Toyota or PENNZOIL

I'm from a Toyota family. My parents used to buy Toyotas just out of warranty and never did any maintenance on them. When an oil change interval was due my dad checked the oil levels and maybe topped it up a little if necessary - like once a year that is. There was never an engine problem.

If it\u2019s a Toyota it will run just fine even with chewing gum instead of oil, a Subaru will explode one mile past the due service mark.

See how much metal that 08 weight pisswater has generated after only 1.3k miles? Switch to 0w30/5w30 and you'll see a drastic reduction in wear. I know I did.

Forgive me but I’m confused. The Tundra doesn’t have two separate oil reservoirs that I’m aware of and I change my own oil. Also, for what it’s worth mines been flawless since 2022 and almost 40,000 miles (not that that is a lot but just saying).

While I didn't own a 2018 (mine was 2013 hybrid -> 2022 prime), here's my short list:

Electric gives a huge increase in torque from 10-50mph

Mechanic told me the oil came out barely darker than it went in on the last change. ~80% electric miles

I’ll do the 15k oil change soon with Toyota OEM 0w-16, which is made by M1 but has a much higher moly content than the regular retail M1 oil.

My 2009 1.33 likes both 5w30 (or 0w30) and 0w20. Out of the factory they came with 5w30, but toyota later recommended the switch with the 1.33 engine. With normal use and lower speeds 0w20 is best, if you drive a lot at higher rpms than 5w30 would be better (at130kmu/3200rpm 5w30 is smoother).

Great oil, I go with the Ultra Platinum. So far it's been the absolute quietest (based on subjective valvetrain sound) and smoothest driving oil I ever used. I tried OEM, Valvoline, Castrol. Nothing was as smooth as the Pennzoil even after a few thousand miles. I still change it every 5k for peace of mind.

My 2024 Toyota Rav4 Prime XSE has had 2 used oil analysis tests done at 4k and 8k miles on Pennzoil Platinum 0w-16 and Eneos 0w-16. Both results showed both oils shearing lower and out of grade to a 0w-8 viscosity at 100C in 4k miles.

2000s Toyotas. Not really unreliable, but oil burning was an issue on most of these because people did not change the oil on time.
