What say you? I pulled into Love's truck stop and saw B20 at the pump and waved off. Is anyone here running B20 on 4th gens?
If you run B20, you're not supposed to switch back and forth between full Petroleum diesel and B20. Use only one or the other consistently. I haven't seen it enough to know i will always be able to get it. You're also supposed to change both fuel.filters when you switch.
I believe they say B20 is only approved for fleet trucks that always refuel at the same place using the same fuel?
2016 manual states you need to take to dealer to have something done to run b20
I seem to get good mileage with the B20.
You need to check the owner's manual for your particular truck. Each year is different so you can't just say 3rd or 4th gen truck. The reason the truck needs to go to the dealer is because IF the truck can run B20 the truck needs to get programmed for added maintanience intervals. The fuel filter change requirements are increased with the use of B20. It acts like a great solvent and any fuel system deposits will plug the filter faster. If you have a fuel system failure and you are running B20 or higher and the truck was not updated they do not have to cover the repair.
When traveling in Minnesota I found the Holiday stations pumps tag read up to 15% bio so I don't go there. May have been up to 20% bio
Did you take it to the dealer prior to running B20?
