dgjks6 6 #1 Posted November 13, 2008 What is the oil capacity of a magnum 12 hp? Usually when I change the oil I have a big jug of sears 30W and fill by trial and error, but for the winter I am going to use 10x30. I have 1 quart in my garage. Is this enough?

rick 217 #2 Posted November 13, 2008 I think you will find the capacity close to two quarts. Share this post Link to post Share on other sites

mcwh1950 2 #4 Posted November 13, 2008 if it's for your 1989 312-8 my operator's manual from 1989 said 2 1/2 quarts or [2.3 liters] also for winter air temperature it said for below 32degrees to use sae 5w-20 or 5w-30. if you would like a copy of the operator manual e-mail me.

dgjks6 6 #5 Posted November 23, 2008 Just a follow up. Changed the oil (put in 10w30) and the last post was not up yet and 2 quarts was not enough. It did take 2.5 qts. And thanks for the offer, but I finally found the manual at the kohler website (it was under classics - go figure) Share this post Link to post Share on other sites
