Funny, I started up my Deere yesterday and today, with the same engine.

Smoked a lot for the first 4 seconds.

It's got 1 year of service on it. 43.5 hours.

It is likely because everyone believes you have to put in a lighter oil than is recommended.


The "thinking" man's friend.

My 21 year old Kawasaki 501v smokes on start up infrequently, especially if parked a while on a slope then restarted. I noticed this the first summer I owned it and mentioned it to the dealer. He said not to worry about it and it will clear up after running a few minutes. I haven’t and it does. I’ve never had to top off the oil and it runs as good as ever.

I have a Kohler Command Commercial and I call it the "Smoking Kohler" It has almost 700 hours on it and smokes no more or less on some startups than when it was new. It has had decent maintenance done on it.

10W30 is what Is recommended and what I use.
