Little known fact, in the us, and I'm sure just about everywhere, all fuel comes from the same place in the area. There are pipelines that distribute gasoline and diesel in each general area (some are quite large areas btw) there is a very large tank farm, where trucks pick up fuel and take it to gas stations. The certain additive mixes including ethanol, depending on the brand, are added at this distribution hub. So the base feedstock is the same. That's why getting premium gas from a high dollar station (shell, bp, mobil, etc vs a Casey's or other discount store) is worth it in saws, because the additive mixes are much better. Even better if you can find a non ethanol premium somewhere. Diesel is the same, the smaller gas stations that cater to small trucks will not have the good stuff, and don't go through as much fuel as the big rig places, meaning their tanks are way more likely to have water issues because it basically just sits there. In either case, you are looking for high volume fuel sales, with premium admixtures, and ideally no bio or ethanol. If i had the room and was running equipment and trucks like most do, i would look very very hard into getting fuel delivery to a private tank, where i could specify exactly what i was using. That way you get fuel at a discount, fill at the yard, can run exactly what amounts of stabilizers and additives you want, can filter it as you fill, and can avoid spikes in fuel cost if you plan correctly. Many construction companies do exactly that, because it's easier to control fuel than deal with fuel issues in equipment. You can also get an off road grade if you have enough equipment to justify it, just don't run it on the road lol. You would need to run more than saws to justify it for gasoline, but if you have a gas stump grinder or chipper, you could probably do just fine. Just something to think about moving forward.
