i hate biodiesel. ...going back to crude oil
I'm not sure why you switched in the first place. If you want your mileage to go up, then limit your use to B2. It might go up from increased lubricity. There was one study done in Canada that showed that.
I've been using B100 for over 8 years in a '03 Golf TDI (at 155,000 miles now).
I've come to understand that chemically, it is the petroleum that is "garbage". Petroleum diesel is a highly variable, chemical cocktail of very dirty components. Surely you've noticed the smell and the dirt associated with filling your tank with diesel? I've you've done three tanks of biodiesel, you've noticed the difference?
Mileage? I often get 49 mpg on petroleum and generally get 44 mpg on B100. That is about 10% less mpg.
So... why did I keep using this for 8 years? It hasn't been easy. There's no B100 filling station down at the corner.
With B100, no or hugely reduced likihood of:
...spills like we had in the Gulf of Mexico
...support for dictators that fire on their own citizens; so we can keep our naval base in the Persian Gulf
...terrorism because
we support repressive regimes
...10-year wars in the Middle East (deaths, wounded, PTSD; our people
and their people)
...extreme weather events (it used to be a 1-2" rain was amazing, last week, we had a 4.5" rain and no one batted an eye)
...huge destruction from flooding; west coast, mid-west, east coast, down south; all over
...HUGE ecological destruction like the mining of Tar Sands in Canada
...sending billions of dollars overseas, just to see some of it fund terror
...leaving other countries stuck with the pollution from oil, so we can drive to the mall
My tankfuls in those 8+ years aren't enough to truly make a difference in these events. I hoped, through personal demonstration, to show it was possible to break our over dependence on foreign oil. Sadly, from my writing and personal appearances over about 5 years, it seems to have had very little effect. Still, at least I was able to hugely reduce my own personal connection to the events from the list.
If your thought was to save money or increase mileage with B100... I'm sorry, that generally just doesn't happen. It has always cost me more.
If you want to consider costs, think about what petroleum has cost us for spills, wars and flooding. It is a big number.
I can understand how you can "hate" an inanimate object like fuel. It is basically how I feel about imported petroleum.
