Ok so I was filling up today and went to grab my jug of supertech 2 stroke oil out of my toolbox, I grabbed the jug and poured about 2 cups of it in my tank when i realized it was some used 10w40 that came out of a gasser. Then I grabbed the right oil and put in a quart like I always do. Ive heard that motor oil in a diesel is ok, I'm just wondering if its gona mess me up or not? Oh and I just did the pre-oem fuel filter if that helps.

Thanks

With the extra fuel filter you will probably be fine... just as long as the oil wasnt full of metal flakes or water.

I would fill up again when it gets alittle lower to help delute it maybe...

Someone with some more knowlege will chime in and give you a better answer.

dang

as already stated, it should be fine. if the oil was thick or had deposites, they should be caught in the filters. just don't make a habit of this:D
