Does anyone know anythign about prolong enginer treatment? I bought an 8oz bottle since it seemed to be the best stuff at the store, but curious if anyone knows of anything better, or something that would be good to add as well, to help protect the car, as well and even improve mileage.

I've tried "recover" last time - but it seemed to make it worse (I run synthetic), and I know for the gas, I usually add chevron injector cleaner, but this last time used slick 50, which actually seemed to do a beter job...

Any reccomendations?

Since I run synthetic in my cars, I use Lucas Synthetic Oil Stabilizer. I also use Lucas Gas Additive and Lucas Auto Transmission additive.

Lucas makes good products. I have used the Lucas auto transmission fix and has helped with my slipping tranny

My brother used Prolong in his Hyundai and he says it works great. I've always used Marvel Mystery Oil and that's what I attribute in part to my 200sx lasting over 225,000 miles and going strong when I junked her.
