It's quieter and turns smoother now

I have added 3/4 of a quart of your Oil Stabilizer and my 3400 GM engine with 92k on it, and it's a lot quieter upon startup now. I also am using the Trans Fix ( 24oz ), and the shifts are noticably smoother, hesitation is greatly improved, and heat has been reduced as well. I am further using your power steering fluid after replacing the rack/pinion. It's quieter and turns smoother now, so I'm using Lucas in just about every fluid in the car now. It's the Lucas Grand Am!
