I know all engines burn some oil even when they e in good condition. What is normal oil consumption for an Atomic Four engine in good condition?
Engines burn more oil than normal when the piston oil rings are new and have not seated, or when the cylinder wall/pistons/piston rings are worn excessively or damaged. It usually takes 100 to 500 hours for oil rings to seat, however the process can be accelerated by using special “break-in oil” [we recommend John Deere break-in oil]. Synthetic oil should not be used right after a rebuild, it is so effective a lubricant it can permanently prevent the rings from seating. Use synthetic oil in a new engine only after about 200 hours or the rings have seated and there is no evidence of oil consumption/exhaust smoke/crankcase blow-by. Some motorcycle and car race engine mechanics have a special procedure to seat rings quickly… they accelerate the vehicle from about 1/4 maximum rpm to 3/4 maximum rpm using short full throttle blasts in as high a gear as possible without lugging the engine. This puts a lot of pressure on the inside of the piston rings, which forces them out against the cyli
