How Much Ethanol is in my 93 Octane Fuel?

[happydays]

The Fed takes 5 cents off the Federal tax if you add 10% ethanol. That .05 crucial for profit margins at small mom and pop stations. Some terminals are selling premium w/out ethanol, the retailers I deliver to charge a dollar more per gallon for it. Just get a lead substitute to add lubricity to pump premium and save.

In germany, regular an premium have Ethanol. I really think its the same for you guys, and something that is beeing done for years now.

Thank you. I belong to a Facebook outboard motor group and one of the subjects that comes up is people stating " buy 93 octane because it doesn't contain alcohol". This is false, a myth, an old wives tale or whatever you choose to call it. The ONLY way today to know for sure you are buying non blended fuel is to test it yourself. Test kits are cheap and readily available.

Thanks. I have been looking for specs sheets on mobils regular vs supreme. It's best that I test it myself. I really hope I'm not overpaying for supreme. (50cents more)

Use recreational fuel in your small engines. If you use them often in the summer months, normal gas is ok, but in high humidity environments or if your equipment sits for a bit, use ethanol free recreational gas. If you put your equipment up for the winter. Fill the take completely with recreational fuel. Sta-Bil doesn’t help. If you don’t, pretty good chance I will see you and your equipment in my shop to clean that carb and replace fuel lines. 👍👍. Fuel good, ethanol in fuel bad. 😂😂

Its in its name, what do you think an octane number represent ( and not its not only fuel efficency ) but how much precentage of aditives you have in Petrol for example 95 is 95 %Petrol, 5 % Ethanol, 93 % precent Petrol and 7% ethanol, e10 10 % ethanol 90% Petrol , those names and numbers arent for comercial reason

Been running 87 ethanol in my fleet of mowers for 20+ years without a problem. You just don’t let it sit for a long period of time
