gasoline additives took out my TOYOTA

LouiTheshopperstallion January 20, 2026

Sorry to be contrite — I no longer have faith in gasoline additives because of this product. Find a good gas station you enjoy. Just fill up with 87 gas and the oil companies have plenty of detergents and cleaning soaps in the regular pump gas No more wasting money on false marketing. Additives do not make your engine better.

A fine product indeed, it helped both my 2013 Nissan Altima SV and my 1999 Dodge Ram 1500.. They were both getting low mpg beforehand and now they have came alive and are doing a whole lot better mpg is back and with more pep at the throttle. I highly recommend this fuel injector cleaner to all. It's money well spent.

i have a 93 toyota 22re engine and makes the engine run and idea smoother. I've used it for years and haven't had a reason to try something more expensive.

Good for the price

Heather October 7, 2025

Does a good job keeping my gas mileage up. It's not the best on the market (those are a little more expensive), but if you use this every tank, it will help. Decent product. My dad used it for years and he worked at General Motors for 30 years, so that's a pretty good endorsement!

Gamut Fuel injector /Carb cleaner -worth a try

Gary October 17, 2026

Fuel injector /carb cleaner I use as some of my vehicle collection sits for Months and the Gas in spite of STABIL does go flat and on the Fuel Injection engines I felt for its low price it was worth a try . Time will tell , but for now all are starting and running smooth
