Formula Shell.
I posted before that I bought a jug of QSUD 5w-20, but couldn't find a single quart of it anywhere. I've searched high and low, to no avail.
Some have said to go with Pennzoil, but I snagged a bottle of Formula Shell for 1.95. Think it will be fine as the last quart (6 totalfor the stang) in the mix?
it's all SOPUS to me.. lol.
