Are they good to add to your car.
I have heard alot of talk about this but no mention if they are good for the car.

Oil, Tranny ETC; Will this harm the engine in any way and the Tranny if i add this to it??

What do you guy's think?

 

If you use a high quality motor oil and ATF, they are redundant and a waste of money.

 

I'm not sure exactly what kind of transmission fluid i have in but i added a bottle of the Lucas stabilizer and you can feel the difference. The shifts are a lot smoother and some of the jerkiness that occurs when i take my foot off the gas around 30-40 is gone. I also tried the power steering stabilizer and that got rid of some of the squeaks and whining when the wheel is turned all the way in one direction. If your looking for something to spend cash on, i'd reccomend these.
