What happens to lube oil dilution by fuel when using DFT #1500 “Hammerdown”?
Lube oil dilution by fuel oil occurs when piston rings fail to prevent ‘blow by’ because they cannot float freely. (A small amount of ‘blow by’ will occur even in new engines; excessive ‘blow by’ should be avoided,) When the rings are kept free of carbon deposits by using DFT #1500 “Hammerdown”, ‘blow by’ will remain within design parameters and excessive dilution of the lube oil will not occur.
