Default Re: Proper Break-in Procedure with Opti 2?

Most all profesional engine rebuilders and engine rebuilding companies for autos, tractors, and aircraft engines, warn to NEVER use synthetic oil for break-in. It lubes too well and keeps the crosshatch from seating the rings. If the crosshatch doesn't do it's job well in the first 20 miles, it gets smoothed down and the rings will never be well seated and the engine won't produce optimun power or longivity.

These are well documented and proven facts
