Use it constantly to offset the damage ethanol can do to the fuel system.

I ordered a gallon for $27.99 and received 8 ounces. I then got a refund for the purchase instead of the gallon I wanted! They gave the 8 ounces for free but I, the customer wanted the gallon I paid for!!! Not happy here !

I have used this in my boats for years and in my SUV when I am not driving it very often. I have never had an issue using ethanol in either.

Sta-Bil Marine product
Apr 23, 2020
I have been using this product for twelve years on my antique car and have not had any fuel problems what so ever. Any of the auto parts stores only sell the small bottles and usually not the Marine product I use. Keep up the great work. I will be ordering directly from you from now on. It doesn't pay to go store hopping.
Sta Bil 360 Marine 1 Gallon
SidewinderJun 27, 2016
This Sta Bil 360 Marine is a GREAT product. Best in my opinion. I have been a Mechanic for over 50 Years and this new fuel we have E10 is hard on everything. Just because it says Marine on container. Don't think you can't run it in everything. Stop and think. A boat lives on the water and has more of a chance to get moisture in the fuel tank. Also most boats are not run every day like a car/truck/lawn mower/ect. That is why Marine Sta Bil has more detergents and chemicals in it and the treat rate per gallon is less. So it costs less per gallon.
