Jeez, you made me pick only ONE Lucas Oil product I use? I use about 7 of them: oil stabilizer, transmission fix, fuel treatment, power steering stop leak, 90W gear oil, gun oil, and tool box buddy. And I love them all.

My best story regards the Power Steering Stop Leak. I had a leaky steering box (Land Rovers are well-known for those). So I just evacuated the entire reservoir and filled it up with your Stop Leak. It's been problem-free since I did it well over a year ago, and the steering runs very smoothly.

The gun oil is also an outstanding product; leaves a very nice film to protect my Walther P99 for a good , and the lack of a strong odor is also very nice. I even gave a bottle to my dad for his weapons.

My Discovery proudly bears a Lucas Oil decal on each rear side window, and it will do so for as long as I have it. Thank you for your wonderful products.
