The other day I stopped at a Pilot station to fuel up. I was mid way through fueling when I noticed the small green sticker on the pump. B20. No wonder the price was better. I went ahead and filled it. Later looking at literature on new DMax it says you can run B5 without any problems. My 01 isn't recommended to run any mix of bio. I'm already smoking like a chimney anyway so I didn't notice any difference there. I towed my 14,000# trailer and it ran and pulled great. My next fill will be regular diesel but I'm wondering what problems I might be in for if I snuck back for more of the cheaper fuel occasionally. I've seen other vehicle recomendations for B5 and B15 but so far the only blend I've found around here (NW Indiana) is B20. Would appreciate any input.

Been running B20 in everything I own that is diesel for almost four years now and the only problem I have is not working on my fuel system components when I am bored!



Also, Moved to Bio.

The only real problem you MAY encounter is a plugged fuel filter. Just carry an extra fuel filter and tools to change it with you.

Shouldn't hurt anything, it's still 80% reg #2. I have run several tanks of B20 thru my 05 with no problems. If you do run it regularly be ready to change the fuel filter b/c the bio cleans out the tank and lines of all the gunk that has built up over 8 years.

It will not hurt anything. have a spare fuel filter and dont run it when it gets cold out. Ive been runing waste veg oil in my truck for 65k and it still runs fine.

IT will be fine. I have run 3 tanks of B100 now. Just carry a fuel filter as stated above.

Thanks for the response. That is what I thought but it never hurts to get someone else's view. It kinda sounds like it's a better fuel choice (except colder climates) because of the lubricity being better that straight up low sulfur diesel. I've been adding 2 cycle oil every couple tanks just for that purpose. I have an injector or two hanging up slightly and it smokes now. Ran all the tests and nothing conclusive, they just wanted to change all of them at my expense. Tried the forced injector cleaning and wasted $275.00. As long as I run the 2 cycle oil it seems to keep the smoking toned down a bit and I'm hoping it will free up some day. Time to change the fuel filter any way so I'll stock in another.

I too had an injector hanging up. I added Power Service Diesel Kleen (Silver bottle) to 2 or 3 tanks at the stronger dose per the bottle and that cleaned it up. Worth a shot.

My 2003 Silverado LOVES the B-100 I make in my Bio Pro 190 much more than pump diesel, especially since the deployment of ULSD. It's smoother, quieter, smells better and gives me a GREAT feeling bypassing every gas station while I flip them the imaginary "bird". The ONLY downside is about a 10% power loss which is about 2 mpg less, but I have a Predator tuner so the engine is putting out a lot more power than the 300hp/520Tq GM designed.

see if you can find some B100 and run a tank or 2 thru it might loosen up that injector!!
or 2 or 3 times the Normal amount of Diesel Kleen. It won't hurt a thing,,

Biodiesel can be just as good or better in many ways compared to regular #2 petro. Manufacterers dont like it becuase its a new market and home brewers can screw things up with a bad batch.

Just dont tell the dealership that you are running more than B5, they will find any reason to blame a problem on that.

Some commercially available biodiesel is out of spec becuase it has been stored improperly or has just been stting around too long. You can make better biodiesel at home if you wanted to.
