" I purchased my 2005 Chrysler 300 c Hemi with 180k on it.  I started treating it with Petron Engine Conditioner and Fuel System Cleaner.  Before treatment i was Avg. 19.1 MPG.  Now with the car over 270k on it I have been averaging 23.8 MPG!  No major engine issues either! Here's to hitting 300k!"-Brad J.

"I purchased my 2013 Ford new, and have treated it with Petron Engine Conditioner from day one! I now 353k miles on it and not one serious engine problem!  Oh and the Fuel Improvement WOW!"-Charlie O.

Bike Week 1991 (the 50th) in Daytona was the first time I ever heard of your product. Some guys had a display of your product with an inline 6 250 Chevy on a run in stand they were running with no oil pan on it. The damn thing even had a mirror under the motor, you could look in the mirror and see up into the block. See the crank spin, pushing the rods/pistons up and down. I thought they were cheating and running it off the starter, but they weren't. They'd run it (with absolutely no oil in the thing) for 10 or 15 minutes, shut it off, cool it off and (when most engines would have welded themselves into a single chunk of iron) then they'd fire it back up.
Been using your product ever since.

 I have a 2010 Lincoln Towncar.  I drove the same highway every week for 6 months.  I was averaging 19.8 miles per gallon.  I added the Petron Plus Engine Conditioner and added the fuel cleaner as well.  My mileage went to 22.8 miles per gallon!  I am a believer in this product and they have a Happy Customer for life!
