Randy, I buy the Tru Fuel red quart cans in the 50:1 mix. I think they're around $6.50 each..maybe a bit higher. I also have a 'gallon' of the 4 stroke Tru Fuel that is 96 (?) ounces. I think I bought that to run through my generator when I exercise it occasionally and for the first fill of my 2 stage snowblower.
I've seen that brand at Lowes &Tractor Supply, cheaper than the Husqvarna brand
a gallon is 128 fluid ounces, I bet that "gallon" can you have is 110 oz
only 2 stroke I have are 4 Husqvarna chainsaws, the 395xp is a gas pig when I'm milling with it, a whole tank of gas + refill before I finish a slab cut
I also have a Ryobi ER160 2 stroke rotary hammer, but it's 25:1
