  • what grade of gasoline recommended?

    New bobcat with kohler 23hp. Regular, mid grade or?

    Did it come with a Kohler owners manual? It should be in there or I would call Kohler and talk to them. All gas today contains some alcohol so I wouldn't let it set in the machine to long.

        Everywhere around here is 10% ethanol. Used to be up until about a year ago you could go to Maryland just 10 minutes away and get clean gas but now its 10% too. I was thinking mid grade but I was also thinking too much octane would make it run hot. I'm gonna look in my manual when I get home

          I wonder if the engine welders do well with fuel stabilizer additives? I've heard they help prevent some of the carb issues if fuel with ethanol sits in a carb too long.

            With my old welders I always put a little Lucas fuel treatment in the gas. They all still run pretty good so I guess it doesn't hurt

                Lucas is good stuff by this fuel additive chart. intresting info on fuel additives.

                  Octane rating has zero correlation to engine or combustion temps. It's purely a measurement of knock resistance. I would run what the manufacture recommends.

                    When all else fails read your manual, says 87 octane minimum. Gas up to 10% ethyl alcohol, 90% unleaded is acceptable, E15,20&85 should not be used.
