Should my Kohler use this much oil?

    I have a Ferris 60 (or maybe 61'') 30HP Kohler Z and between oil changes (roughly every 50 hours), it uses about a quart of oil. I asked my dealer and he said it was pretty normal for a machine to use a little oil and to not be worried. I just thought I'd get another opinion (you guys-lol). The mower has about 500 hours on it, I service it roughly every 50 hours. The air filter is kept clean as well. The mower 2 years old last month-I generally sell my mowers at 2-year intervals to keep it under warranty, but due to economic conditions, I cannot afford to do that this year--so I may be asking more questions-lol;

    Your dealer is a FOOL!!! he thinks that almost half of the engines entire oil volume will be burned off every 50hrs or so and that's normal :hammerhead:

    Not knowing your exact Kohler model and spec :confused: I would say to check for a bad breather reed valve. I just had a Kohler on a LazerZ that would go through almost a full qrt. in 8hrs.

    I just downloaded the manual and located it and it said to be suspicious of the RBV if excessive oil use-so thanks! I'll double check on that tomorrow-

    If you plan on doing this job yourself I would plan on getting a couple of extra parts so that your only doing this job once.

    1. Reed valve(24 402 03-S) list $1.10
    2. Breather Gasket(24 041 64-S) list $5.72
    3. Breather Filter(24 050 11-S) list $1.05

    HA-I burned this much in oil this week! lol; thanks--would you say it's a repair for a NooB like myself (in the mechanic's dept.)?? or should I leave this one up to my trusty dealer??

    I'm a little worried about your dealer:dizzy:but I would say you may want to leave this one for someone with more mechanical experience. But I never discourage people from trying their own repairs........ thats probably because I charge more for finishing jobs that I didn't start:laugh:

    IS3000/IS3100 use a CV. Big difference in amount of work involved to replace something you don't even know if it's bad. Are you getting any oil up in the intake tract? Before you do anything involved, may I suggest you just change you brand of oil? See if you can find Kohler 10W-30. All oil is far from the same. DONT USE ANY ADDITIVES. And your dealer may very well be a fool. But not on his advice about this subject. You want to pay about 3 hrs labor for inspection? Variables are endless on this issue.
