Hi all. So I think I found what could be a mistake. Some background info on this:
So I was calling Toyota to ensure that getting my next summer oil change in 5W-30 will not void the warranty. I used the text on page 381 in the
Subaru owners manual (Thanks to *Axel from his thread:
https://www.ft86club.com/forums/show...=owners+manual)
It states higher viscosity is required at high temps, so it says you can use 5W-30 oil.
Here is the anomaly: The Toyota rep told me that she doesn't see that, in fact, she sees "5W-20" in the Toyota owners manual, on the same page.
That makes no sense.
1. Both owners manuals should be the same regarding the engine....they are the same engine!!
2. Even if there's something different, the whole point of changing the oil (as the owners manual is literally stating) is
for higher temps... It's the
second number that describes oil behavior at higher temps.
Right? 5W-20 and 0W-20 will have the same behavior at higher temps.
So, do you think it's a mistake on Toyota's part? Shouldn't it say 5W-30 like Subaru states, and not 5W-20?
