My B27 is burning oil. I’m on oil “change” 4 at 56 hours. Used Kohler’s 300 hour synthetic the last 2 times and that might as well be water.
At 56 hours, it should still be under warranty. I would have the dealer look at it. Most oils get pretty thin when hot, in air cooled engines. That Kohler 300 hour synthetic oil is pretty high dollar to be changing that often. It’s a 10W50 synthetic oil. May I suggest using Valvoline VR-1 20W50 conventional oil and not changing so often. Or, a conventional 15W40 Diesel engine oil. Do your oil changes as outlined in the Kohler engine owners manual. Your dealer likely has a oil filter cutter. Have them cut one open and take a look inside.My B27 is burning oil. I’m on oil “change” 4 at 56 hours. Used Kohler’s 300 hour synthetic the last 2 times and that might as well be water.
Yep, there’s a good bit of zinc in it. However, the Valvoline VR-1 20W50 and the Motorcraft Super Duty 15W40 are also loaded with it. And, both are much cheaper than the Kohler oil.Personally I have switched over to using 15W50 Synthetic with zinc additive here for my customers' oil changes.
Does the engine smoke? Especially when idling? Have you removed a spark plug and looked at it? Oily?My B27 is burning oil. I’m on oil “change” 4 at 56 hours. Used Kohler’s 300 hour synthetic the last 2 times and that might as well be water.
