143 Series Regular Gas Formula

Poured 4oz in a 97k mile MZR 2.3l DI turbo "parts car" tank that was 1/4 full and had been parked from what the previous owner had said "years" so guessing 3 years minimum by the blackberry bramble, water level in the trunk and paint condition. Let it slosh around for the 2 hr trailer ride home, then after a health check reluctantly tried to fire it up thinking the gas had to be as bad as the paint and mold condition. I was blown away when it fired up first crank, and even idled down no issues. It's possible the PO had put some gas treatment in it prior to "it just stopped running" (when it was only a bad battery) but I didn't find any clues amognst the mold. I give it all to Star Tron and their Enzyme Fuel Treatment. My father used it in all of our boats and never had any issues with water during storage in the PNW. I swear by this stuff now for any project car in the future and to clean up the e15 that is now in all the pumps.

I've been using in everything gas powered cars, trucks, motorcycle, snowblower, lawn tractor, mower,etc since 1998 haven't had a carb or injector issue since. Winterize just run till dry then fill even with last season gas in the can start right up! Worth every penny

Could not empty last years generator tank, so added a few drops of this and started straight up

Got my Generac Generator running like new after the nolead gas went stale..

Good product Added to 1 1/2 old fuel. Engine burned fuel without issue. Recommended Purchase

Easy to use. Easy to store. Value for the money. Compatible with what I’m using it. I’m using it for some ATVs. Also lawn equipment so it’s versatile.

I have been using this for many years. It works great at stablizing gasoline.

I've been using Star Tron for many years and it is the best !! Amazon sells the large bottles at a good price.

Uso esto para mi generadora electrica de emergencia que prendo de vez en cuando. No he tenido problema.

this is the best fuel additive on the market been using it for ten years and it out performs any made of chemicals. cleans well and enables long standing motors to start without a problem. too bad it is so expensive and hard to find used to be stocked by Canadian Tire but is no longer.

If does the job and the gas stays for 2years

Absolutely a must have for every Outboard engine. My mechanic & I have talked over the years for hours about fuel additives. With his 30 year experience & my 8 years of owning a Outboard this is the only fuel treatment my engine has ever seen. I have never had any issues & do not worry about ethanol-related phase separation, plus the fact it also cleans carbon deposits while keep my fuel stable

a must have for me ( I use regular gas )...If you haven't used it yet, you should feel the difference right away...more power, idles better, startup RPMs will drop right away...and on and on
