REV-X Adrenaline Gasoline Fuel Additive - 8 fl .oz. (4 Pack)

I have a 1996 F250 with a 351W in it with 320,000 miles on it and would throw the engine light on. It was also running sluggish. The code said HEGO sensor was bad, but I decided to try this additive to see if it would clean the sensor off before I spent the money for a new sensor. It worked, truck runs better and the engine light stop coming on. It did take running 3/4 of the tank down before I noticed the change going into effect.

Poured a bottle into my mother's car, and one in mine at fill up time. Haven't driven the whole tank out yet. No idea if it's making an improvement. No issues though on either car after putting this in. I'll be trying the rec x oil treatment next, as I've seen some real world test results on extremely powerful engines and how well it worked at thwarting recess damage due to loss of oil pressure and other extremes.

I can feel the difference when I add the fuel additive in the power increase and responses form the car handling.ok

Used in my 2007 Lexus rx350, caused mis-fire. 3 fil ups and it's still causing problems. Mis fires every time.

Product is amazing. However this is the second order I’ve received where it reeked of fuel additive outside the box and one of the produce had about a quarter missing (leaked out). So improvement on packaging is needed as I use this to race my bikes and every ounce is necessary.

Awesome additive for a daily driver or a vehicle that is garaged most of the time. Have been using these products for years and they do not disappoint

This is the best by far I have used , I put it my tank and my son hase same car & motor we drove 200 miles I had 3/4 tank he had half it ran great we put same amount air in tires both had new oil change both had new tires both had same amount of passengers I'll buy moor
