FIVE HUNDRED MILE BREAK-IN
NOTE: DO NOT use synthetic oil during the break-in period!!! It is not recommended, required, or necessary.
For your engine’s first 500 miles, avoid hard acceleration for sustained periods. Periodically change the engine speed while driving to help seat the rings. After the first 500 miles, change the oil and the oil filter. BluePrint Engines does not find the use of synthetic oils to be necessary, or beneficial. If you must run synthetic, it is only advised after 9,000 miles and only on roller cam engines.
Synthetic oils by composition are thin, and “slicker” than fossil oils. They tend to increase leaks and can promote improper break-in. Please take this into consideration before changing to a synthetic oil.
FOR FLAT TAPPET CAM ENGINES: We recommend the continued use of BluePrint Engines BPP10W30, or approved oil with zinc or a zinc additive for the life of your engine.
FOR ROLLER CAM ENGINES: Without catalytic converters installed, you may also use BluePrint Engines BPP10W30 or a standard, non-synthetic 10W30.
MAINTENANCE DURING THE 500-MILE BREAK-IN
- During the break-in period, check all fluid levels frequently.
- Recheck external bolts that may loosen with use or heat cycles, such as intake manifold, headers/exhaust, front accessories, etc.
- Change the oil and oil filter every 3,000 miles, or 3-4 months if the vehicle is not driven regularly. If your engine is used in a heavy duty or dusty environment, the oil and oil/air filters should be changed more frequently.
- In colder regions, lower viscosity oil may be required for better flow characteristics.
- Use 91 octane gasoline, unless otherwise noted on the recommendations tab of your engines specific product page.
