    Has dual "7" gallon tanks but I can run em dry and each will only hold 6ish gallons.

    I use ethanol free 89 octane gas.

    Lucky to get 8 hours mow time.

    I swear it feels like I used to get 11-12. Am I going crazy or do mowers really lose this much efficiency as they get older? Is there a problem I should be looking for to try and fix?

    May sound obvious but make sure the air filter is clean and the oil is changed often. It makes a difference.

    Our walkers are getting 8 hour days on 2-3 gallons. They are 23 HP with 42" decks. But keep in mind that an 8 hour day is really only about 4-5 hours of mowing.

    Also, why are you running 89? does your manual specify that? We run 87 with ethanol with no problems what so ever.

    I run the 89 bc its the only grade without ethanol around here. Figured better for the motor and better for GPH.

    When I say 8 hours im talking about on the hour meter. So doing around 1.5 gallons per hour. I swear it used to be around 1 GPH.

    Air filter, oil and filter, plugs are all up to date.

    Pull the heads, seat the valves and clean all the carbon build up. Might want to do a rebuild while you have it apart.

    My mower is using a bit more gas right now as well. In this case it is the lush Bermuda, Dallis grass and crabgrass that is taking more power to cut.
