M18 Oil Question
 

Im changing the oil in my 1872 this weekend with 5w30 for the wintertime and i was wondering if you guys had any suggestions on brand and type. thanks

Lot's of oils these days are not well suited for older air cooled engines. I run Kohler 30w in my 1872 year round. I have a recently remanufactured engine. No probs starting in the cold with the 30w and I figure Kohler's oil has what Kohlers engines need. I'm sure many others would be fine as well but the dealer is on my way home from work so it's no big deal to grab a couple of quarts of oil from them.

I use kohler 30wt also in my kt17 series II year around. I think the manual may say 10w30 for these current temps in conn

Most modern oils are backward compatable, any good quality oil would be a good recomendation and in cold weather, the multi viscosity oil will work to an advantage with possibly slightly additional consumption.
As with any engine, give it time to warm up before increasing the load/speed.

Thanks for the replies. I went with shell rotella 10w30
