    KEEP AN EYE ON YOUR OIL LEVEL!!!! Just a heads up, I got a '12 x series with the same kholer engine. From day one engine had been using oil to the point every 50 hours had to add half a quart. 240 hours into it and was fed up took into the dealer kholer looked at it and replaced the engine. Now into '13 season and guess what still using oil, I thought I was doing something wrong. Talked to the service department and found out that they sold two of those engines one being mine and have replaced both mine and the other persons engine, same reason..... Love the mower its a tank but something is wrong with the Kholer 980CC or 999CC... I hope they have fixed the problem. Good luck with the mower.

    Fuel gage on those things are hit and miss. Some times I can start a yard on a full tank then in the middle tank is on quarter of a tank... I've ran two hours with the low fuel light on went to the gas station filled up 8 gallons on a 12 gallon tank. Not the best fuel gage in my opinion.

    Myk, How many hours do you have on your machines?

    That's some rough oil usage! Had to be some poor QC on clearances or a batch of bad woppershafts:laugh: came through or something. Since the engine replacement hows the oil usage now on the new one?

    1/2 qt in 50 hrs is very acceptable by Kohler's standards (not mine), I just talked with Exmark last week and was told they were seeing oil usage during the break-in period, whatever that period may be I don't know.

    I have been told by Kohler engineers at their factory more than once, that 1 oz per hr oil consumption on their air cooled engines was acceptable. I find this hard to believe, 1 oz per hr would have put your engine at 50 ozs, or 1.56 qt in 50 hrs, that is a poorly built engine by tolerance standards in my mind, and I've owned many Kohler engines.

    I have found through the years if a engine begins using oil from day one, it will continue using oil, maybe to a lesser degree, but a certain amount of oil will be added between changes.

    Engineers will tell you that burning a small amount of oil in an a/c engine is part of the cooling equation, how small that amount may be, I have no idea. I've owned Kohler engines of which I may add a few ounces between changes, but I've also owned the same engine where no oil may be added. This so-called cooling part of the equation does not seem to hold true where all a/c engines are concerned.

    I'm honestly very surprised Kohler would OK a dealer engine swat with that small amount of oil consumption, yes, I am really "extremely" surprised. I've had their engineers make the statement, "we will not get into a warranty claim situation until a usage of 2 oz per hr for an extended period can be documented." With this statement, I'm not sure if the people were just stating their thoughts, or if in fact that was company policy. As with your engine swap, if this is company policy, it was not adhered to. I think in your case this may have to do with a good dealer, distributor, manufacturer, working relationship.

    I got 420 total hours on it now, about 150 hours on the new engine. Still is dropping my oil level from full to the add mark in 50 hours. We are trying to see If maybe It has been over filled and the dip stick is off on reading the actual oil level ( I know sounds weird ) just watching it real close to see if it drops past the add line. It came due for a oil change last Friday so we shall see if it drops anymore is so, looks like another engine.

    This is my 4th Exmark with a Kohler engine and this one I've had problems with. Other three are great not a big oil useage like this new one. Yeah I get the oil usage for breaking in a new engine but I think I'm past this point. I know at one point Kohler had them replaced the heads on the original eninge to see if that would fix it, when it didn't brought it back in the broke down the engine and so happen a kohler rep was coming by they looked at it and said replace it. What exactly was wrong with it I'm not sure. I just got a new engine so I wasn't to concern thinking maybe just had a lemon engine.

    I'll post more later, but half a quart in 50 hours is perfectly acceptable to me. My old 28 EFI if I worked it REAL hard would use some by the 50hr mark, but it got changed then anyway.

    Myk, what brand and weight oil are you using?

    I am also interested in anyone's oil consumption stats.

    This oil usage issue is why I am not a fan of Kohlers anymore. I grew up using them, and have always been very happy with them until the last few years. Now, I see more issues mentioned here, or hear of more issues at a dealership with Kohler than any other brand. My CV730 in my brand new Z720 used about one third of a quart in the first 8 hours, then after the oil change (recommended by Deere at 8 hours), it used a quart plus in the next 32 hours. Not accaeptable at all to me, and it is embarassing to pull up to a job with new or at least clean looking equipment and then start my Z and blow a cloud of smoke so large, that you could hide an average sized garage in it.:rolleyes:

    The last Kohler I had before that one would also use oil more than any of my Kawi's by a wide margin, but still nowhere near as much as on the 720.

    Im still not over Kohler's hydraulic lifter bleed down problem...I will never forget that clatter sound right before swallowing the valve. Although several dealers and factory reps have told me those days are long gone. My next mower will most likely have the EFI Kohler.
