Interesting.
Our standard gas (petrol) is 10% Ethanol and usually is available in three grades: regular 87 octane, plus 91 octane and premium 93 octane. E85 which is 85% ethanol is available in some places (not around here) and is cheaper than regular and also less energy=less gas mileage/gal. But not all cars/trucks can use it.
Right now gas is about $3.73 reg, $4.03 plus and $4.33 premium. Diesel is about $4.28 but it is NOT bio and that includes road tax which is $0.995. Around here we can buy off road diesel at the pump and then they add on sales tax of 7%, so about $3.50ish.
You can do the G->L and $->€ calculations.
EDIT: I found a converter so $3.73 = 0.87 €/l and Diesel would be 1.0 €/l
Interesting indeed
I have lived old enough to remember here was pumps with even A 76 grade inside. To use that
moonshine in our Moskvitch my old man put one more gasket between head and cylinder block. Thus reducing compression in cylinders.
ignition has to be adjusted either. Obviously power has been reduced, but that was ok, as then people wasn't rushing
Now that is long gone. 30 years for sure.Probably you have noticed - E95 and E98 (often branded as "super") are only octane available here.
But as an owner of BMW motorrad I am reading few NA rider forums, and I have noticed that your folks made a lot of complaints about gas quality in US. IMHO in car you can't feel petrol quality difference so badly as you notice differences when riding (performance) motorcycle
Our gas now-days have ~ 10 % ethanol either. If that is for fast turnover, I don't mind. But for devices which have seasonal use that ethanol is pain in a$$. Especially if there is carburetor. That's why for snowblower and chainsaw I am buying special synthetic petrol. It is more pricey than e95, but that feeling when you simple fire-up saw with first pull after 6 months being silent is priceless.
As for shopping experience I can agree that often you will find a limited selection here.
And businesses are trying to cheat. OK, our system is metric and normally here was used decimal fractions. If we take butter as example. There was 200 gr, 500 gr and 1 kg cartons. Now those
innovators have created 180 gr, 450 gr etc. Price of one carton remains the same, but now they are 10 - 15 % smaller
But US system to show prices without tax, imho is beyond crazy. Why would consumer need to know net price, if he have to pay full sum at counter ?
