B4 - 4 Stroke Break In Oil

B4 Break-in Oil and proven process is developed for proper break-in on any Four Stroke engine. Recreational or Race, proper break in determines both the short term life and performance of all engines. Dumonde Tech B4 is a very complex formula that allows proper ring seat, work hardening and impregnates parts with a matrix compound film to protect surfaces against lean periods and corrosion in part by modern fuels which are increasingly acidic. Through research R & D, it has been found that a high percentage of these processes are not achieved with conventional oils. By not achieving these effects, performance and durability can be greatly effected. Each bottle come with our proven break-in process. Benefits: Increased performance gains Less engine failure Greater cooling Increased protection of parts against corrosion Available sizes: Quarts and Gallons.
