I'm a newbie here and you guys have helped me a lot so far.
Yesterday I spent 3 hours driving looking for pure diesel or the 5% blend until I ran out of diesel and had to put in the 5-20% blend (only 2 gallons to get me home)
I was browsing through the forums here looking for pure diesel or 5% blend stations, but most seem outdated. So my few questions for the seasoned diesel owners:
1) I know VW claims you can use up to 20% biodiesel in 2011/2012 TDIs (their website) but then due to emissions they said to use 5%. Is anything over 5% actually BAD for the engine? (for the 2012 jetta model)?
2) If I tank a blend higher than 5%, should I use an additive? And why? What would the benefits be? I tanked the 5-20% blend last night and my TDI seems to be running louder now.
3) If I had the choice to get a 5-20% blend from like Shell (which I consider best in my Chicago region) vs a 5% blend from like Speedway or Marathon (which I may be mistaken but do not think they're that great), which should I choose?
Thanks again guys. Love this forum!!
