What engine oil do you prefer,??.

Ran Joe Gibbs break in oil than used his 15/40 weight mineral for the first 10,000 miles than have switched to the full synthetic 15/40 Joe Gibbs, Solid flat tappet. Have to agree with Rusty Maintenance is the Key.5000-6000 miles will dump oil & replace filter and just to add as you might think im a nutter i use earth magnets on my oil filter and a sump plug magnet.I even use them in my Tranny sump and diff.
