I Added The Lucas Oil Stabilizer and There Was an Immediate Result.

I have always had a loud top end on my Harley Sportster. And ever since I started using this oil [Lucas 20w50 Motorcycle Oil], my engine is quieter and have noticed much better my motorcycle is running overall. I added the Lucas oil stabilizer yesterday and there was an immediate result. I LOVE Lucas products and as a motorcycle mechanic for Harley Davidson, I tell everyone I know with Harley’s to use this oil. -

I depend on Lucas Products whether I'm chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me. My machines seem to love Lucas Products better than the rest. Less plug fouls, less smoke the machines running better and smoother. Thanks Lucas

When we got out of the car we noticed right away that almost all of the noise was gone!

My son's 2005 VW GTI with the 4 cylinder turbo and 127K miles on it sounded like there hammers inside the engine. The car was close to needing a oil change so I bought a quart of High Mileage Oil Stabilizer. He changed the oil adding the stabilizer started it up and we took it for about a 8 mile drive. When we got out of the car we noticed right away that almost all of the noise was gone! He has a 200 mile drive back to school in a few days and I'm willing to bet all of the noise will be gone by the time he gets back to campus. Thank you for a great product!
