I have been a diesel mechanic for 20 years in the late 80's is when I first encountered Lucas Products, when a truck driver pulled into the shop with a broken axle cap. He bought the Lucas gear lube supplement and drove 200 miles into our shop on it! Today I have a stubborn front seal on my power steering pump on my tracker. To replace the seal would exceed the value of the Tracker. I keep adding the powering steering seal and it keeps getting better! The first time I added it new life was brought to the steering system! It steered like a brand new vechicle. I use almost every Lucas oil product for my SUV!
