bottle rocket... the Harley EVO aluminum motor solved that problem... my 93 80 cubic inch V twin is 127,000 miles old and never a drop to "mark it's spot"
Yes we use conventional oil (dino) to properly break in the rings because full synthetic has way too high a shear strength to let the low tension rings used these days to ever fully seat.....
There are a LOT of doubters.... and they would be the same folks who fail to read on Royal Purple, Lucas, and other full synth web sites the recommendations to use dino first.....
So do not take Old Smart and Fred's word on it, do some simple research and decide for your self
OR be the typical owner... drive it as is.. and sell it in Two~three years for a new car
