What type of oil do you recommend in your engines? I'm running valvoline 10w40 with one bottle of zddp.

Thanks,
Walter Boss

That sounds fine Walter. 10w-40 is what we usually use.

Thanks Jack.

And when I say 10W40 I mean dino oil not synthetic.

Sweet. Just checking since I've heard guys talk about mulit-viscosity oil are bad specifically the 10W40. It leaves too much “gunk” behind in the engine. I thought that was a thing from the past...back from the 80s?

Unlike the "guys" I'm no engineer..... but my experience tells me to change my oil every 1000 - 1500 miles and my motor is as clean as the days it was built. That has been the case for the last 15-17 years...
