Still too new for anyone who wants to do an used oil analysis or extended oil change yet. I am currently running it in my 02 Silverado 5.3L and probably do a UOA at the end of this year.
Wally world has the 5-20 for just over $18 5 qt
I picked up two yesterday online with free shipping
I'm going to use it in a 2015 F350 6.2L with XG2 Fram
