1 liter is 1.19 GBP
1.19 British pounds = 2.371551 U.S. dollars
1 US gallon = 3.78541178 liter

You do the math. I cry every time I gas up over here.

Only $9 USD for one US Gallon? That's not as bad as I expected, but still very expensive. I've heard of an $11 USD per US gallon equivalent at one time.

I wonder if people in Germany have decided to drive slower on the autobahn because of the increase in fuel costs.

I never complain about high gasoline prices and I have not adjusted my driving pattern because of it.

However, I do worry about the stagflation it will cause everywhere else.

I only use premium unleaded fuel from Chevron or Shell. To use 87/89 is very poor for the ignition timing of the vehicle. There also may be a small power loss and a small penalty on fuel economy. I once saw a BMW 750i at a Shell gas station in Irvine I frequent filling up on mid-grade. I felt so bad for that car I really wanted to go up to the owner and plead him to give the car premium and I would pay the difference. Poor poor poor car; a 750i wasn't designed to have such a cruel life and be living on mid-grade. Must've been a leased car. I still feel sorry for this car, even though this incident was observed nearly three months ago.

Is this for a different car than the W203? I thought all W203s had a 16.4 gallon tank.

Dot, user error. I used to run only 93. I switched to 87 about 4 months ago with absolutely no difference in the behavior of the car.

Yea I think that has to be off. It is 16.4, but if you add in the 2.1 gal reserve mentioned in the manual, then that's close. Maybe he got some gas going up the fill pipe???

you both need to re-read his post... he said he went to a gas station and the car (unknown) which was previously there pumped $85 worth of gas / ~ 18.5 gallons.
He was wondering what type of car it would have been. The pump doesn't zero out until you begin your transaction, so it's simple to see how much a previous car pumped.

Most likely a huge Escalade or Hummer.

I pump that (18+) every time I fill up my old Jeep Cherokee. Lots of U.S. manufactured cars have 20-22 gallon tanks. The Hummer H2 has a 32 gallon capacity! At that pumps $4.57, a H2 fill up could cost around $145!

What do you guys think about Octane boosters? My old MB mechanic on my old 1984 380SL told me they do something to the catalytic converter that is not good.

I could not run 87 on my older MB V8 beasts without knocking.

Have you guys heard of this?

I saw this on eBay advertised for C Class Mercedes, they do make others to fit our fuel lines. Makes me crazy thinking about all this.

Mercedes says NO to fuel additives and suggests they aren't really an economical alternative to premium fuel.

I recently read an article about poor fuel quality and random testing done for government required detergent additives. The investigation began after GM found themselves making unexpectedly high fuel injector repairs in the state of Florida. Off brand gasoline of all grades often tested below the required levels. Testers found that when the suppliers advertised high or quality additive content, they not only met, but exceeded by many time the government required levels. Shell and Chevron were 3 to 5 times the minimum on average.

Other additives prevent carbon build ups on intake valves and elsewhere.

Cheap gas may not be just an octane issue.


I'd have to see some independent tests of the fuel line products. Seems a bit of smoke, mirrors and snake oil, but I think most people trying to sell me something are full of bs anyway.

this is wat I never understand about ppl using a lower octane...especially with gas prices being higher it actually makes more sense to get the higher octane...the price diff is usually about 20-30cents (not dollars...cents)...and lets say your tank holds about 13 gallons by using a lower octane you save somewhere between $2.60 or $3.90 and if you paying $4 a gallon you paid about 52 to fill up so your talking about paying 52 or 54.60 to fill up...someone pls explain the big deal to me

I have hard time finding 91 octane in Northern NJ. It is always 89 or 93. Does anyone know what companies sell 91 octane?

BTW, Shell V-Power goes for about $4.30/gallon give or take.

Article in Washington Post over the weekend said that we still pay a lesser percentage for gas than in 1980...and I used to just drive my dad's car with my friends like there was no tomorrow....Lord, please forgive me.

Recently I was reading the Wikipedia entry on superchargers. One of the sections, devoted to octane states,

"Higher octane fuel burns slower at the same temperature than low octane fuel, reducing the risk of detonation. As a result, the amount of boost supplied by the superchargers could be increased."

Maybe you guys all knew that, but heck, I learn something every day...

Yet another reason not to deprive your kompressor on the next fill-up.
