Gas Consumption between 4 mix and 2 cycle

[Fubba]

I bought an FS 80R about a month or so ago. I bought a BR 600 about 2 weeks ago. The FS 80 has to be filled up ALL the time. It's crazy how much gas it uses compared to the BR 600. The 600 has a bigger motor and still probably uses 25% of the gas that the FS 80 uses. How do the 4 mix trimmers compare to the FS 80? Is it as noticeable as the blower and trimmer?

Our Two cycle fuel expenditures have been 18% higher for the 4-mix hand Helds, over their two cycle sthil counterparts .

Takes more gas to make more power.
