I recently ran two bottles of Amsoil's Performance Improver through my truck for the initial treatment on a 1999 blazer 4.3L(w) with 160,000 miles to clean the injectors.

After the initial treatment, coupled with a 2 oz dose every tank full, I have successfully got 24 mpg on the highway with a straight 70mph.

The idle is almost but not quite so smooth that you can't tell it's running except for the tach.....and pickup has improved as well.....

I think this is a good product and wanted to share with you...

Found it at Mills Fleet Farm and it's about $7.00 per bottle....

I was getting a routine 19-21 mpg which is good, but I am trying to do everything I can to milk out MPG's since gas just jumpted to 2.25/gallon here in western wisconsin.....

Any FYI .....

Excellent report.

Just as an appendix to your report, using fuel additives constntly is not recommended seeing it will eventually ash foul the plugs. I know this from experience.

Also, don't substitute this treatment for doing your routine maintanence and tuneup work.
