Ethanol in Gas

This seems to be a hot topic lately. Any input on using premium fuel in these old workhorses? I know the octane level is higher in the premium, but I also know they contain no ethanol. Will the high octane cause issues with ignition in these low compression engines? For myself, the price is really no issue as I only run my N about 30 hours a season.
 
I haven't seen any issues with my gas tractors as a result of ethanol. I shut off the fuel on all of them as soon as I turn it off, so it may cause the needle to leak and I don't know it.

Smaller things with "rubber" fuel lines are a nightmare because of that stuff. I think it is a combination of things being built cheap and the ethanol, but those rubber lines and primer bulbs on trimmers and blowers last about 9 months.

I do know that gas smells more like a skunk than the fuel we had when I was a kid.
 
Some brands of "Premium" gas contain ethanol. Some brands of unleaded regular do not. Have to read the labels on the pump to tell for sure.

Higher octane won't hurt. Won't help, either.
 
Some does and some doesn't. In a outboard boat it is not recommended to use gas with ethanol. At the "Lake" premium fuels, without ethanol are popular....
 
I always buy premium fuel for use in small engines because it was once true that it did not contain ethanol. This, however, is likely no longer true.

Here is my take on the Ethanol gas question. I use ethanol gas in my two 8N (48 and 52) I also use it in my push mower, riding mower and chain saw. The one thing I always, always due is add the correct amount of STA-BIL into my gas cans before filling them. I have been doing this for the last six years and I have eliminated all starting issues in any of my equipment.
Just my .02.
 

I run BR regular in every thing I own and never had a issue...
I often stop at the BP station and add fuel to a customers car that's near Empty... I get the best mileage/power out of BP on my personal chit.. Try it....
 
Mercury outboards will not be warranteed if you use red Stabil. They make a green Stabil for use with ethanol gas. I switched to Lukas.
 
Just going by what our local fuel supplier has advertised on it's pumps. Regular and mid-grade have ethanol and premium does not (as advertised anyway). This spring was the first time I've ever had issues with "old" gas, and it hit every poece of equipment I use, mower, trimmer, chainsaw, tiller and my 8N/2N mutt. As I said, I don't have an issue with the price difference for as much fuel as I go through a year in this stuff.
 
on your tractor, run whatever you prefer
It won't care one way or another as
long as it is Clean.
old, questionable, contaminated, 2-stroke gas dumped out of small engine tanks, whatever....
all of it gets strained, mixed with fresh and dumped in a tractor's
tank here. Tractors don't care, as long as they are kept tuned and running optimally before.
(again, clean is more important than composition)

small engines, I'm a little more picky.
fresh is best
more important IMO, is run-em often
don't let them sit with modern gas in them for months.
I do 'start-up' days when I'm not busy or waitng for parts sometimes.
Everything with an engine here gets started and run for a bit


Thanks for the tip on BP, I'll give it a try
 
premium does not guarantee no ethanol.

there is 1 regualr station in my 3 city area that sells no ethanol. it happens to be a premium pump , no ethanol. but every other of the 450 gas stations in the towns sell ethanol premium.

i could also dreve 45m to a marina or airport and get no ethanol gas.

that said. i run low octane fue;l. easier to ignite.

ethanol, for now.. is here.
 
Depending on where you live, the EPA mandates Reformulated Gasoline and the Requirements
change from summer, winter and location. Ethanol is one of the requirements, depending on where you live.
