[Haoleb]

Im planning on doing my own oil changes from now on and while looking through the paperwork from when i had my truck serviced with the 75k mile maintenance it says they put 8 quarts of 15w40 oil in there. Huh! Now i know it doesnt take 8 quarts, and i thought the tundra V8 uses 10W30 or 5W30.

I also plan on using Mobile 1 synthetic and Im not real sure if it would be better to buy the 5W30 or 10W30, The oil cap says 5W so I assume that would be best. But being in hawaii im not worried about the oil being too thick when its cold because it just doesnt get real cold. I have searched the arcives but never found anything real definitive.

I believe in the haynes manual it said to replace the seal on the drain plug, is this something that needs to be done? And where would i get one.

Thanks For the help. This might be beaten to death already but hopefully we'll get some good info for future searches.
