My Cadillac running rough. Service Manager said I could have expensive service done, but suggested this product instead. End of rough running engine. I've been using it for over a year, every thousand miles.

The BEST to keep your motor and fuel system running great! The 20 oz bottle is the best. It;s good to stock up when on sale. Don't even bother to buy or use anything else. This just works! Love this stuff.

I used Chevron Additives for the longest time now. To start, I always use high quality fuel, and do regular maintenance which includes Chevron Fuel Additives. My plugs show clean burning and no carbon build-up. My mileage is on the upper end for the vehicle. I have my oil tested and it too, show a clean burning engine with little carbon. Let's not forget the Smog Test, this too show a very clean burning system. So if this is a sign that Chevron does what it said, I'll take every time.
