My wife's 99 Soob Legacy hits the big 100,000 in a couple weeks so it is tuneup time. I tried the 3M Fuel System Cleaner 8813 this time around. Being from 3M it seems like it would be a decent product. At $11.86 a 16oz. bottle it is pricey but I figure the car had earned a thorough cleaning.
One unexpected benefit after using this 1 bottle is the fuel gauge is now reading accurately again.
I recently started a thread in the Mechanical section about this problem. inaccurate fuel gauge I was prepared to pull the fuel level sending unit from the Soob and clean it but this stuff did it for me. {SWEET} Previous treatments with Techron, FP or Lucas did not effect this, nor did I expect it.
I went back to NAPA and bought a second bottle to run in my Nissan which has had a funky fuel guage since I bought it used 7 months ago. I'll report back on what happens with it in this application.
I would assume this stuff is too strong to use on a regular basis but it could be the ticket for a deep cleaning. I would definetely replace the fuel filter after using it just to be safe.
