this is sort of correct. For motorcycles (my area of specific knowledge) there is special break in mineral rich non syth. The minerals help scrub the engine as well as bond to it to ease with it's operations. Once the engine is broken in, it is safe to use syth.

edit: Also - 100:1 is WAY too lean for my blood. I have a cr80 dirtbike that I do a 32:1 in (jetted @ sea level) and it will get a little gunky if you're not on the pipe, but unless you weigh less then 100lbs, anything less then 40:1 mix, regardless of oil brand, you risk burning a piston or grennading that engine.

good luck and best wishes
