I was in Illinois this past weekend. I needed fuel so I went to fill up, and four gas stations later all I could find was 10% biodiesel. The owners manual says no more than 5% biodiesel. What happens when that is all they are making? Are we all screwed?

I read that some guys are complaining about poor mileage with B20. I was thinking yesterday about filling up with B20, but not if mileage goes down. Also, you may have gelling problems in the cold.

I ran B20 in my '02 lb7. First an only time. Power was down, obviously. The mileage dropped as well.

There's no way in hell B10 is going to hurt your motor.

The only reason you have a drop in mileage is because the fuel cleans you system and puts all the waxes and parafins in the filter therefore plugging it up and dropping your economy. Changing the filter once you have run two or more tanks will bring your economy back up. I have been running B20 in my truck since I bought it, and thus far only one filter and better balance rates on my injectors. My economy has come up from 15mpg to 16.2mpg since I changed the filter and still running B20, even in -10* weather without gelling.

B10 wont hurt your truck what so ever, so dont be afraid to run all the way to B50 if you have run Bio in the past.

THE reason GM and Ford do not support more than B5 is because of quality reasons, not because the engine will not run on it. B5 has an "industry accepted specification", mixes greater than that DO NOT.

This means that you can be very assured that B5 is a quality fuel, but that B10 can be almost anything the refiner/supplier wants to sell.

Bio-diesel made form animal fats is BAD BAD JUJU, and will gel at temps close to 40*F. Well "gel" is not exactly, the CPP (clouding Pour Point) is more accurate, but the affect is gelling. B5 must be vegitable based, B6 and higher, only god and the supplier know what was used.

Someone posted that "there is no way B10 will hurt your motor", well that's not completely true. It might be for a DMax, but the CTD and PSDs are severely affected by low fuel pressure, and you can do serious damage to the injector tips if fuel pressure is too low.

i live in a warm semi-warm area(SC) went to mountains in NC found a place with B10. Going up the mountains I was wondering if i left the engine at the gas station. I had only about 8k on the truck then so I wonder if it was "cleaning it out" or just lower cetane. Its been 10k since then and a fuel fliter change no problems now. Just thought that at 8k not much to clean and clog on my truck but still had lower umph to it.

A diesel wont have much build up on the fuel system until it reaches 100K. So a newer truck under that should have zero to very little problems with filters.

Straight from the National Biodiesel Board wesite.

"Ensuring consumers have a high level of confidence in the biodiesel they purchase is a top priority for the NBB and key element in the industry's continued growth.

Regulation of fuel standards is a function primarily left to the states. However, regulation of biodiesel and blends is not uniform across all states.

The NBB is undertaking a project to work with states to catalog information regarding their authority to regulate fuels; their status in adopting ASTM D6751 as the fuel specification for biodiesel; enforcement procedures; and to assess their capacity to analyze samples."

This will hopefully ensure by the end of this year that when you go to the pump to pump B20, it is surely 20% bio, and when you get B50 you just put 50% of a farmers crop in your truck or car.

Hope this helps,
Tony
