Average price of gas is not $2.99 as a national average. That is the average of the cheapest-gas state in the US: Texas.You can save even more using regular pump gas (87 octane) and mix small amounts that you use right away. The only real down side of using ethanol is if it sits for a long time. I use 87 octane and use it within a week or less and I run my saw till it runs dry or I dump it out and run it dry.
Try calculating regular gas at $2.99 where average fuel cost is.
The national average is $3.76 as of November 17. I get E-free for ~$4/gallon, but I decided to calculate using a more conservative estimate of $5/gallon so it applies to everyone that can get E-free or wants to use premium 93 octane.
Yes, you can use regular and crappy 2-stroke oil and save even more money, but that wasn't the point I was trying to make. I was pointing out that running "Premium" engineered fuel over the life of a saw is going to cost a lot more vs running a home-made/pump "premium" mix.
Personally, I store a lot of gas. Because I want it to store a long time (2+ years), I store E-free. This also means I use my oldest gas in my saws and cars and rotate out old stock.
Also, I have saws I don't use often. Using E-free across the board makes it so I don't have to worry about draining tanks every time I go to use one for a day and am unsure when I will use it next. This is HUGELY cheaper than using engineered fuel for that same purpose.
