These changes create gaps that standard viscosity oils might not seal effectively, allowing oil to burn and blow-by gases to escape into the crankcase. Using a viscosity that is too heavy can reduce fuel economy and hinder cold-start performance, negating the benefits of the specialized formula.
How High Mileage Oil Restores Seal Integrity and Extends Engine Life
Key Additives and Their Role The difference between conventional and high mileage formulations lies in the additive package. The enhanced seal integrity can restore oil pressure and eliminate the rattling sounds associated with hydraulic lifters.
Viscosity Grade Best For Typical Performance 5W-20 Newer high-mileage vehicles Improved fuel economy. This specialized formulation is engineered to condition seals, reduce noise, and maintain protection where it is needed most, ensuring older engines continue to perform reliably.
