New Boss 302 specs 5w50
Interesting. To beef up the 5w20 rated bottom end without a design change, I wonder? Or is the boss not the new 5.0 block? I thought it was.

This is why I chose an oil that would remain a 40 grade throughout it's usable life, have higher amounts of ZDDP that is commonly found in API SM/SN formulations, thus providing much better protection with less wear than current 5W-50 formulations on the market.
Amsoil 10W-40
This is what I use in the Shelby, and she loves it!
