Urban Myths

Rather than high jack someone else's post, I figured I'd start another.

Urban myth: Fuel injection is responsible for low cylinder wear in new engines.....WRONG!

It is a contributor, but not the major cause, as it is possible for an injector to leak by for what ever reason and wash a cylinder down, just exactly what you blame a carburetor for!

Better metallurgy.....I'm not so sure......most iron that is poured now is recycled metal, fluxing to remove impurities is the bare minimum, examine how current iron oxidizes vrs a 40 year old block, the current iron doesn't rust the same.

Better lubricants, a help but not sole cause

Biggest reason for lack of cylinder wear is removal of lead!!! Search SAE (Society of Automotive Engineers) papers related to lead and cylinder wear.

I read this 30 years ago...............
