It only has 250 hours and it uses about 8-10 oz. oil every 10 hours. Ive had the Kawasaki dealer do a compression test and a lead-down test, and was told the results were all great the engine is in fine shape. Well I think the power is a bit on the low side, but I dont have another one to compare to. I have had a Kohler for four years and never, never seen it use anywhere near that much oil, ever. Its the oil consumption that worries me. Im afraid we will go three days without adding oil and burn up the engine (we add every other day). Kawasaki is very reluctant to make any warranty claim on this engine, so Im wondering if anyone else has had a similar experience dealing with Kawasaki on warranty. If so, Id appreciate your tips and suggestions.
