"OIL STABILIZER & POWER STEERING STOP LEAK............ BEST! products EVER invented for automobiles of any kind. I have a 2005 Chevy Impala with now 183,000 that I started using the engine stabilizer in at about 100,000 miles just because I wanted to try it. It now uses NO oil between oil changes and the engine is strong as ever. I feel strongly it is doing its job by making my engine last. I'm going to see how many miles it will take me. THEN.... very recently my power steering pump started making a lot of noise. It was winding loud at turns, take off's and the steering was stiff on the turns. I checked the fluid level and it was a little low but not low enough to effect anything. I then stopped at an auto parts store and picked up the STOP LEAK and put as much as I could in. The fist day not much difference. Second day a little better. Third day it is like someone opened my hood and replace the power steering unit. NOT ONE SINGLE LITTLE NOISE. It is like new again. No kidding. I am amazed and will tell everyone I know about these product. I am also lucky enough that Lucas Oil sponsors my football team's stadium here in Indianapolis. GO COLTS!!. I wish I worked for this company. To work for someone and for something you truly believe in would be a pleasure. Believer for LIFE............" -Chad V.
