Cobra Owners Preferred Engine Oil Brand?

[Three Peaks]

I guess I don't see this Cobra engine as any different than any other engine I've owned or built and I've always been partial to Valvoline in all of my engines. Once in awhile I'll use Quaker state and Pennzoil in a pinch, but usually Valvoline 5W-30 wins out.

Now that I'll be running flat tappets, I'll have to add a ZDDP additive at every change, but that is chump change to insure reliable performance and life of the cam/lifters.

All but one, that is... and you can't break that one in with Rotella. But, fortunately, you have the two bottles of liquid gold that I sent you....

It will get Rotella after it's broken in. During break-in, it will get Joe Gibbs or Brad Penn, and nothing else....

Your "liquid gold" went into my lawnmower.
