Went in the local Autozone yesterday and happened across some SL rated 10W30 Valvoline VR1 full syn yesterday, it was marked clearance price of $3.00/ quart and then the cashier rang it up and took an additional $1 off each qt as part of some Valvoline promotion!! I bought all 10 qts they had.
Is this stuff any good? I just did an OCI with it in my 01 F150 this morning, with the very high mileage I wanted to go with something thicker for the summer months than the 5w20 or 5w30 that I've been running as the ol 5.4 is getting noisy on the thin stuff. It seemed VERY quiet on startup and overall seems much quieter running than before with my previous OCI of MC 5w20.
