Lucas High Performance Assembly Lube is designed for mechanics and technicians to pre lube bearings, cams, lifters and valve train.
Jay R. uses Lucas Heavy Duty Oil Stabilizer in Chevy Express 1500 Van
I have added a bottle of Lucas Heavy Duty Oil Stabilizer everytime I have changed the oil every 5,000 miles with conventional oil. The engine still purrs like a kitten with close to 65,000 miles on it. I can't wait to switch to Mobil 1 Extended Performance Oil and Lucas Synthetic Oil Stabilizer to extend my oil change intervals.
I also use Lucas Heavy Duty Oil Stabilizer in my van's rear diff.
In addition, I have used the Transmission Fix in an old car of mine that had tranny noises and they went away.
