Star Brite 478192 Fuel Additive Unisex Adult, Blue

2022 F350 Super Duty Dually. Purchased for the sole purpose of preserving diesel fuel in my gravity feed tank in bed of truck as I buy in bulk and often do not use the bed tank fuel unless prices jump or I am pulling my RV. I poured the recommended amount (1st time use) into the onboard tank and took off for a weekend drip of 8 hours round trip. My engine seemed to quite down a bit. Fuel economy was pushing about 2 and sometimes 3 mpg better than I normally get. 2 to 3 mpg over distance sure adds up quickly. I have since run two more tanks on this product and still getting better fuel economy. I am sold that it works. I suggest start with the small bottle to see what it does for you. Keep the small bottle cause you will buy the large "gallon" size and portion it out :).

use it on my gas items (cars and weedeaters/leaf blowers) and my diesel items. One gallon bottle is the worst so buy something to use to measure the fluid.

I work out on the road and am always traveling. I drive a diesel and diesel isn't cheap. I use star tron for better mpg.

Seems to do the trick. Helps clean injectors on my marine diesel engines

Great Product will be a repeat purchaser .
