time for an oil change....

What oil are you guys running? I have a 1991 impulse.

I use Mobil 1 15w50 in all my boat engines. The 15w50 has the correct additives for both flat and roller lifters. You can buy it at Walmart for 22-26 dollars for a 5 qt jug

Since I don't know anything about oil, I asked Vince. He told me to use Valvoline VR1 SAE40 racing oil. The whole "racing" thing sounds fancy, so I've been running that. It takes a little effort to find. Maybe I should switch to the Walmart Mobil 1 stuff.
