Attention: TDR Forum Junkies Well, after a lot of prompting, we poured the 100% Blue Sun biodiesel (B100) in last wednesday at Bandimere, and tried it out.
On the first 2 passes, it was a tenth faster than petro. On the last pass, in the heat and with the fuel setting we were using it should have ran a 9. 45 on #2. On Bio, it went 9. 301.
By the way, 18 passes on the car with NO BREAKAGE! transmission and TC is living great!
The engine runs smoother, less white smoke (from the higher cetane) and smells good. The turbos spooled better than ever. We normally have trouble getting 20 PSI to stage, this shot it to 35 faster than ever.
All research I have done shows it to be good stuff, if you use virgin product: No old french fry oil. Look for soy, rape seed, or other specific grown fuel crop products and try it out. Most of it you will find is 20% bio, and 80% petro, called B20.
Other advantages: Lower HC and PM output, but slightly higher NOx (minimal). Higher lubricity than petro. Good for the farmers, and is a renewable product. NOT FROM THE MIDDLE EAST!
Downsides? It will gel up at a higher temp than petro, so be careful in artic conditions. At 20%, should not pose an issue.
Good/Bad point? It has a strong detergent characteristic, and will clean up your fuel system, so be ready to change your fuel filter a few miles earlier until it cleans it out.
