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).
On 0w16 the engine is smoother, more responsive, quieter and consuming about 0.2L to 0.5L less fuel per 100 km.
Toyota OEM oil is very high quality stuff with lots of wonderful additives that are good for a long lasting engine.
I’ve been happy with the 0w20 in my 1.8l Corolla.
The only thing I noticed that my 03 Camry burns more oil when I was obsessed with 95, im usin 91 now though its still burning oil but not as much as 95.
10w30 toyota motor oil sa gas (vios,wigo)
Really looking forward to getting that first break in oil change done and go full send. I do have a giant problem with this car though... I F'N LOVE IT!
