Lucas Oil Products 10001 Heavy Duty Oil Stabilizer 32 Ounce Quart

I heard a knocking noise coming from my engine. Performed an oil change an added the entire bottle of the Lucas Heavy Duty Oil Stabilizer (HDS). Noise disappeared after about 15 minutes of allowing the car to idle, and giving the Lucas HDS enough time to circulate throughout the engine. No more noise and the car runs perfectly - it's been 2 weeks now and still no more noise.

ucas Oil products never disappoint, and this Heavy Duty Oil Stabilizer is no exception. I've used it in multiple vehicles over the years, and it consistently helps engines run smoother and quieter. It thickens the oil just enough to add extra protection, especially for older engines or those with higher mileage. This 32-ounce bottle is the perfect size for a single treatment, and you can immediately tell the difference in how the engine sounds and performs. It also helps reduce oil consumption and improves pressure, which makes it a great maintenance product between oil changes. Overall, this is a dependable additive that delivers exactly what it promises. It's one of those garage essentials that's worth keeping on hand — especially if you're working with older vehicles or doing regular engine maintenance.
