Somebody may have discussed this topic before but I couldn't find anything. I have ran regular gas station diesel in my 2305 since new. Last week I was in my diesel camper and the station had off road diesel 50 cents per gallon cheaper. I googled it and found its due to not paying the road tax,( putting in the camper would be tax evasion ). With all that said, I'm curious if its okay to run off road fuel in my 2305 ? , and if so, do I need to add any additives. Thoughts ?
