The best advice is, if it ain't leaking oil something is really wrong. And run it like you just bumped your head. Mike   [Reply]  [No Email]

Most newer diesel oils are low ash. Make sure the API- CD-II spec is on the jug, that is the oil spec for a 2 cycle Detroit diesel. The reason for the low ash oil is that Detroit 2 cycle motors have a little piston ring very near the top of the piston, called a "fire ring". Oil with too much ash can cause fire rings sticking in the ring land.   [Reply]  [No Email]

The not idling it is more of an issue than the oil. Drive it like your mad at it and it will be fine. Also don't try to lug it down . It will fall flat on it's face.   [Reply]  [No Email]

Also change it twice as often. I am running 15X40 in a Detroit. I think Valvoline Racing 40w would be good but would be hard to find. HPO Valvoline 40 is what you should use, but I don't think it is available. All the oil rigs with 2 cycle Detroits on them. are using strait 40w if they can get it and 30w if they can't.   [Reply]  [No Email]

Shell Rotella T makes a straight 40 weight for these engines. If you have a detroit diesel dealer you should be able to get an oil there as well. Also check with oil distributors in your area for any of it. Not sure if 30 weight is a good idea or not.   [Reply]  [No Email]
