Well I have some first impressions. I've gone through approximately 300 miles of this fuel so far and I must say I'm impressed. My injection pump has been making a lot of noise for some time now and it has quieted down significantly. Don't get me wrong, it's still loud but there is a perceivable difference before fill up and now. All of the claims of this fuel have been realized by me so far. Pretty interested to see what fuel economy on this tank will be as my numbers right now look slightly lower than normal, but time will tell. My normal fuel is Chevron #2 for reference
In summary:
Quieter operation
Smoother idle
Better cold starts
Less smoke
Fuel smell much less noticeable
Additionally, I know people have been looking for more info on this fuel and I found some more resources. I found that Neste Oil does the processing for this fuel and their website has a lot more info as well
Neste Oil NEXBTL. The brochure is also interesting and can be found
here.
There is a footnote that states" b) Lubricity of 100% NEXBTL diesel is approximately 650μm, analysis report is given with each delivery. The lubricity of the final fuel blend has to be checked and corrected with lubricity additive if need be." The station I filled @ (Broadway, Sacramento) says it has an additive to lower this. I don't know if this was done before or after shipment but I suppose I can inquire about it the next time I'm over there.
Cheers
