Racing Engine Oil Additives
Do all cars need break-in oil?
Brand new cars and trucks don't need to be broken in. Break-in oil is appropriate for racers and competitors who use rebuilt or new crate engines.
How is break-in oil different from regular engine oil?
Break-in and regular engine oil serve different purposes. Break-in engine oil is designed to help the piston rings form a tight seal to the cylinder wall. It is only used for a short period of time to break in the engine. Regular motor oil is formulated to prevent engine wear and should be maintained continually.
How long should you use break-in oil?
Use break-in oil for 500 to 1,000 miles to ensure that rings and seals are secure, then switch to synthetic or conventional motor oil.
