Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power
Basically after engine is up to temp, some 3/4 throttle acceleration and deceleration will help seat the rings better and you have the first 25-50 miles to do this. My friend who is a tech has broken in every engine he has ever built with this method and I have done this on the 3 other new cars I have bought new and they were all nice and tight with no oil consumption.
I was on the back roads with the wife and got on it a dozen times doing some 30- 80 mph pulls. My friend did the prep and I told him on the test drive, he oblidged
If your read the owners manual in a left handed way it is telling you to do this. Of course for liability reasons they dont exactly spell out the procedure.
Also in the plants I have toured, when they pop them on the chasis dyno at the end, they get them warmed up and romp on em good.
I have 88 miles on it and dumped the oil and changed the filter.
From page 106 of owners manual
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detrimental
and should be avoided.
