Deviating significantly from these recommendations can void warranties and lead to premature failure. Older engines with looser tolerances often benefited from heavier oils like 10W-40 or 10W-50 to prevent oil consumption and maintain pressure.
High Temperature Protection: How Oil Weight Affects Engine Performance
This is crucial because oil thickens significantly in low temperatures. Performance vehicles or engines used for towing often require the robust protection of a 15W-50 or 10W-60 to handle the increased thermal and shear stress.
Original Equipment Manufacturer (OEM) specifications are found in the owner’s manual and represent the exact balance of protection and efficiency the engineers designed the engine to run with. If the film is too thin, metal components grind against each other; if it is too thick, the engine struggles to turn over, reducing fuel efficiency and power.

Signs of Incorrect Oil Weight. This high-temperature viscosity determines the oil’s ability to maintain its film strength under the intense heat generated by engine combustion.
