Here in GA the state gasoline and diesel tax is just 7.5c with prices
this week at $1.85 for reg unleaded and $1.95 for diesel. Why, over
the past 2-3 months has diesel fuel gone up about 40c/gal while
gasoline has stayed at about its normal levels?
Diesel has gone up more because of supply and demand. Home heating
season is here and demand for home heating oil, which come from the
same refinery stream as diesel, are increasing. At the same time, the
high peak gas summer driving season is over, taking some of the
pressure off gasoline. It's not unusual to see this happen in a tight
market like we're in now.
We're running into the same stuff in Canada (Nova Scotia, at least).
Diesel went from 81.9 cents per litre to 90.9 a couple of days ago.
Last year, I could get it for 63.9. It was about 20% cheaper than
regular gas, now it's the same.
Last weekend my brother and I test drove a Smart with the CDI engine.
The way fuel proces are going, it's a consideration...
AFAIK, for two main reasons:
* Brazil produces a lot of sugarcane, from which bio-ethanol can
be made by fermentation and distillation. Local shipping then
* Engines burning ethanol differ slightly from those on straight
petrol: hotter or something. Brazil got into the game decades
ago and is geared up to run its vehicles that way.
The rest of the world _may_ run on bio-ethanol eventually, or on
bio-diesel. Engines (again AFAIK) must be altered to handle pure
bio-diesel. In *.UK, what sells as "bio-diesel" is usually 95%
petrol to suit unadjusted engines. I hear that in *.DE they have
gone all the way.
One thing to watch is that different feedstock crops (sugarcane,
sugarbeet, rape (for oil) &c are subject to different economics
in different climates. Cane is good for Brazil, rape for *.EU.
"They" may eventually produce engines suited to all these fuels,
