Not just on here, but other places, too. Folks say they don't worry about using a performance oil with a high zinc level because they think running roller lifters means that doesn't matter.

Well, I noticed something on Jesel's FAQ page that should change that opinion. They say "We recommend soaking the lifters in mineral based oil prior to installation as well as pre-lubing the engine prior to startup. After initial engine break-in, if you are going to use synthetic based oil, we highly recommend oils containing high zinc content formulated for racing applications. Synthetic oils formulated for street use are not recommended due to a lack of zinc content."

Flat tappet cam or not, if you built it to run hard, I think you better run an oil that can handle the wear and tear.



I thought you are rebuilding your engine for the last ten years because you were running no oil


First, I think it's only been six, not ten, years.

Second, since I haven't actually touched it in 8 months, I think I can adjust that value down some, too.

Third, I was running good oil when I hurt the engine, but too little of even the good stuff doesn't offset stupidy and the laws of thermal dynamics.

Such is life...
