500 ppm diesel for non-road, locomotive and marine use will be available at least through 2014. Small refineries are allowed to produce all they need. I suppose whether they do or not depends on local market and demand. Check with your fuel supplier.

I'm not sure what year this machine is. I bought it in March of 2007 with 30 hours on it. This is back when all diesel had sulphur adequate for fuel system lubricity. I always run low sulphur (500 ppm) off road fuel in this engine but when I order fuel this year, my driver will have to go to a...
