Dean Fain, RV Transporter
“As a RV transporter have tried several fuel additives with various results. After using the free trial offer for the 3 ounce bottles that treats 240 gallons and about 3500 miles later have opted to buy 10 bottles of the OTR treatment due to the time of year and the colder temps in northern Ohio, Indiana, Pa and NY where I typically go. I have seen a increase varying from 1-3 mpg depending on weather (wind). Have seen on average 2mpg both towing and empty. Also have a smoother running engine and less smoke.
Also, a review on Fuel Ox® Cold Charge OTR product:
After using the Fuel Ox® Cold Charge OTR for 13,500 miles now have seen a increase of fuel filter life. Normally see about 9500-1000 miles on the driver information center. This time it has not gone to zero until now at 13,500 miles. Also like to say that it works as it says have driven in -6 degrees weather and no sign of gelling.
Just for informational purposes this is a older truck, 2005 GMC Sierra 2500hd, 6.6 liter Duramax Diesel. Makes a little over 500hp to the ground. 375000 miles on the odometer.
Also want to give a shoutout to Al at Fuel Ox®. Great customer service and great personality. Prompt delivery. Love the shirt.”
