LUCAS FUEL STABILZER & CONDITIONER
Lightning ship. Professional packaging. Great communication. I have used Lucas products for many years, very reputable without the lack of confidence. Will recommend highly. As far as for Longevity !! however, Time will tell and I will update if any changes occur. A JOB WELL ORCHESTRATED FROM START TO FINISH. Just perfect! Thank you. Anthony. H Burlington, MA.

A Must Have for All Your Gadgets and Toys
I use this religiously in all of my small engines as well as a motorcycle and dirt bike. Everything runs like a top and can sit in my garage for weeks or months at a time and it still starts up on the first or second try. Great for regular use and for medium to long-term storage of small engines like lawn mowers, weed eaters, leaf blowers, etc. If you want to protect your engines and have them run at optimal performance, buy this stuff and use it every time you fill up. A little goes a long way so all you need is a small splash in your gas cans. Great value for the money and very easy to use.

Missing cap
It was missing the cap when it arrived. It wasn't even in the box so it was packaged without the cap. Luckily the foil seal stayed in tact. I will have to find a cap that fits because I wont use the entire bottle in one use.

Treats Ethanol
I bought this additive to treat the terrible fuel we get at gas stations, ethanol has to be one of the worst ideas ever, it’s bad in too many ways to list, one of the worst characteristics of ethanol is it absorbs water from the air, water in your gas is a nightmare. My motorcycle engine has been modified for horsepower & torque, I had the engine Dyno Tuned, my high compression engine runs best with 94 octane gas, not a gas / water mixture. It doesn’t take much to treat my 6 gallon tank, Lucas is my favorite brand for gas treatment

Excellent and necessary
Running an old vintage car that really needs the best petrol it can get means additives like this is essential. I have used it for three years and find it makes the old VW camper run better.

Paraît efficace par temps froid et humide
Utilisé pour le stockage en jerricans dans mon garage d’éthanol E85. J’en mélange aussi dans le réservoir de la voiture qui tourne à l’E85. La voiture démarre du premier coup même par temps froid. A voir avec l’hivers et les températures négatives. Le ralenti moteur paraît plus stable à froid.
