Vehicles are not effected with this additive when started or ran until tank is empty with treated fuel. Some other stabilizers I used, couldn't wait until it ran out, motors ran rich or stumbled until depleted.

I use this in my cars that I don't drive that much because I'm no retired. Recently my wife took our main vehicle out of town and I had to use my Van that has been sitting for several months. The van started right up and ran great just like when it is filled with fresh gas.

I have many small engines on a variety of equipment that sees little use in the winter. I learned my lesson the hard way of not adding this in the fall. Never a minutes problem with Ethanol contamination since.

Shipping was way faster then expected, and the product does everything it says it does.

Highly recommended!

Used with my 470 hp 347 Ford. Boosted the octane enough to make the difference. Reyes the others with no real advantage. Amsoil worked great.

We have been using it over the winters on our vintage Corvette & ATV and it keeps them running good in the spring

I use this in my snowblower, chainsaws, lawn tractor, ATV and string trimmer. After storage, everything starts up quickly and runs great. I've not had a gummed-up carburetor once.

This is the second time using this product. I used some last year and my lawn mowers did not have any problems starting and running the next season. Usually they would at least start hard or not run smoothly.

good product

This stuff works wonders. I used to have a small piece of property and bought an electric mower due to the carb alway getting fouled. Alsonhad issues with blowers and edges and, even worse, the generator in my RV. This has worked wonders on all, especially the generator. I make sure this is in every tank and/or gas can I fill. I buy by the case directly from Amsoil. Gets here fast and I can't knock the price. IT WORKS!

Maintenance

super !

I put this in my old John deere tractor and it smooth out the engine immediately. I use it in my duramax at every fill up.

This product makes your stored gas last longer without degrading.

I use Gas stabilizer it my stored gas. It seems to help keep the gas fresh.

I have been a Preferred Customer for years. Using Amsoil products saves time and money vice having all of ths work done at a shop, and especially at a dealership. I have a long drawn story I tell people all of time about how I discovered Amsoil and why I have these products for so long. Just not enough room here. I enjoy and trust Amsoil products in all of my vehicles and equipment. 2 trucks with over 250, 000 miles each that I owned for 14 years each and working on third, plus my wife's cars and kids vehicles and 6 grown grand kids (hopefully I will be around to help some of my great grandchildre of which I have seven.

I’ve used this for the past two years in my boat’s gas tank. It holds 120 gallons and I’m unable to empty it at the end of the season but haven’t had any fueling issues since using this stabilizer. I try to run ethanol free gas whenever possible but this is cheap insurance!

I can use this stabilizer in my lawn and garden equipment and my stored gasoline. The equipment starts right away every spring even after months of storage.

This product is great for helping to maintain not only the fuel life expectancy, it helps with the small engine performance. Definitely a great product.
