100LL is "low lead", but a friend of mine told me that it has more lead in it than regular gasoline/ethyl. It would be sure to fork up your catalytic converter.
Don't feel bad. I've just done a calculation which tells me we're paying more than $6 per US gallon in Britain (90p per litre).
The problem in America is due in part to American motorists cravings for sport utility vehicles or SUVs, which are disastrous in terms of fuel consumption. The problem is further compounded by the blinkered thinking that it is their "right" to drive whatever they like, and to hell with the issue of oil resources, which they consider to be "someone else's problem". We even see it on this board - someone posts a pic of the "best" car, which usually means fastest or (more to the point) faster than the car picture posted by the previous person in the thread.
Think of your gas prices as a wake up call. It's time to stop raping this planet for its natural resources. I'm paying at least twice as much for fuel as American motorists pay, but how often do you hear me complain about it? But these howls of anguish about US gas prices appear on this board all the time. Maybe if they would drive something that gets better than 18mpg the pain would not be as bad...
I don't often complain about road fuel prices, but I'm going to do it now. I am outraged that in Britain diesel costs even more than petrol, when diesel costs much less to produce, and less crude oil is needed to create an equivalent volume of diesel. In all the European countries I've driven in recently (Holland, France, Spain, Portugal) diesel costs about two thirds as much as petrol, reflecting its lower production costs. We have the most expensive road diesel in the world. (we also have a Labour govt)
So I'm glad I get 47mpg, and can do 500 miles on a tank of diesel. I do about 20,000 miles a year and spend about £40/week on fuel. At today's exchange rate, that's about $75.
