What Oil Are You Using?

Mobile 1 15w50 High zinc content.

That's what I have been using for over 10years , and Walmart sells the 5qt jug for under $26.

Pulled my 340 down last year after running it since the initial fire up in 1984 for some upgrades in HP.

Everything looked great in the engine with zero problems.

I only run Mobil-1 in my vehicles , cars , truck , motorcycle and lawn mowers
