Good chart from Amsoil. Interesting that the Hybrid oil has better high temperature performance than this the XL. SS is their best oil.

I always find these charts interesting.

If the OE oil is “fine and dandy” and will Lube a properly designed engine for 250k miles before it’s totaled due to something other then engine oil related, then you’d think using the Signature Series oil with 5 STARS should allow this engine to be pulled at the junk yard and thrown into another chassis for an additional 350k miles of use.
