Bottom Line
The LUCAS OIL 10118 High Mileage Oil Stabilizer is a solid choice if you want to extend the life and improve the performance of a high mileage engine, especially if you’re dealing with leaks or excess oil consumption. However, keep in mind the reported frothing problem that could impact lubrication negatively — so it’s best for those willing to monitor their engine’s response or already familiar with oil stabilizers. If you’re concerned about lubrication issues, you might want to explore alternative stabilizers or complementary engine treatments that specifically address frothing.
