[Fot] Engine Oil - FW: Rotella Ask Our Expert

[William G Rosenbach]

Always impressed with the Rotella. Used it in a Renault 17 that I
occasionally flogged up the west side of I-70's Johnson tunnel approach.
Oil temp ran much cooler than Valvoline 20W50. It also looked the same
after the abuse, where the Valvoline darkened considerably.
Would like to have known about it back when I ran the high compression
2.5 L 6 in my GT-6.
