Re: Low engine power during break-in period?

This might sound weird and crazy to someone,but race engines are break in with mineral oil hard,helps the rings to seal.Had a smoking kx450f with lost ponies because of babying it and using fullsynthetic oil,put a new ring and hard break in with minerals and its all good.Hard break in=No wot but hard acceleration&deacceleration.

But race engines are built to much tighter tolerances.These chevy based marine engines are hammer&chisel technology,dont know if it applies to them too.

I would recommend cheap oil and alot of oil changes during break in,there is alot of filings and crap in the oil during break in.

When I used to fly light aircraft with Lycoming engines, occasionally you'd come across a new engine. Then the advice was always to fly at or above 2400rpm power (full throttle was 2500 unless limited by altitude and normal cruise power was 2200rpm).

Also, the dealer on my new VW Golf said that it might burn a bit of oil in the first year or 2 until the rings had properly bedded in.
