I have a 2005 3 s sedan. I have 86,600 miles on her. I have been putting in the fuel system cleaners in after every oil change for the past 3 oil changes. I noticed a difference. There was a little more pep and the engine felt a little smoother. Car and Driver is my favorite read, and i have always seen an ad for Restore Engine Restorer. I never paid too much attention to it. Finally i passed the ad and actually read it. It said it restores compression, oil consumption, horsepower, and engine life. When i read horsepower and engine life i figured i'd try it. On the can it stated that engines over 50,000 miles will see a big improvement or something on those terms. I figured since my car is 36k over that i am destined to feel an improvement.

Today i got an oil change. After the oil change i went straight to Advanced and bought Restore, along with a fuel system cleaner (Shell bc it lasts 5k miles.) I poured the Restore into the oil and after driving around i noticed the car feeling more responsive. I drove about 50 miles today and the car is feeling great. I definitely feel an improvement in acceleration. My shifts feel smoother, and the car over all feels better. It only cost $8, so i believe it was well worth it. Just writing this to inform those with high mileage to check this product out.

 

i can back up this claim as i too have used that product myself, the car just seemed so much happier but i also had full synthetic in it, now that i have no money but was in dire need of an oil change (that really only needs to be done every 8k mi and up) i was forced to use reg oil and if my car had hands it would choke me.

 

My car would run me over at times, if she became Christine. I also noticed no exhaust smell when i would floor it.The past few months i've been smelling the exhaust in my cabin after i gunned it. I gunned it a few times, and i no longer smell it.

 

signs point to an exhaust leak, you would be surprised on how cheap the material manufacturers would use, put the car on jacks have someone start the car and listen for blow by

 

Cool new product to add to my list of stuff.
I also stand by Seafoam.
