(6 pack) Gumout Octane Boost, 10 oz- 510022W

Don't buy premium fuel, save money buying regular grade and adding octane booster. You'll save money. No matter what grade or fuel you buy at a given station they all have the same additive package, the only difference is the amount of octane. If you buy 8 or more gallons at a time you'll save money buying regular grade and adding this booster. It works great. No pinging and no power loss.

we started using this on our 2013 Town %26 Country Van. wow! we went from 19 mpgs on our 3 -4 hour trips to OKC, to averaging 25 mpg. Worth the money? YES. I buy 6 every month for both vans. my other van is a 15 passenger 3500...FULL SIZE. I only use this van for farm feed runs ( when I put 1500 lbs of feed in the back) and major grocery runs. Im lucky to get 10 mpg!, but since Ive been pumping a bottle a month in with every fill up, my intown mpg is about 13. But my highway mpg is around 15 mpg! tremendous for this beast. we took a trip ( about 5000 miles) towing our 28 ft travel trailer from Eastern Oklahoma through 12 western states to California (inlaws) and back. average gas mpg - 14.8 mpg. Now that should be proof enough to to give it a try. Saves me a TON of money!
