Petrol Prices!

[Bing]

Just heard on the radio that the 3p duty rise has been differed until January, which is nice... Except we'll all be skint after Christmas :roll:

I was in the US on hols last week and the average price in Orlando was around $3.25/gallon. Yes their gallons are smaller than ours at on 3.78 litres, but even so, that still equates to only 57p/litre!!

Even the premium unleaded was only around $3.40/gallon, working out at approx 59p/litre.

I was amazed when I put $20 worth in the dodgy Toyota Corolla rental and it took it from under 1/4 to just about 3/4!!

US fuel has always been much cheaper - when I lived there I was paying $1 for a US gallon when it was £1/litre over here...............fuel consumption was not a consideration when buying a car

Yes, the August rise is postponed. After some campaigning to the PM directly, along with my local MP and FairFuel UK, I feel I've had a tiny (one of many thousand) voice that's perhaps helped a bit in this. Good news on a car that does 22mpg lol

Dont forget, US gallons are smaller, and their standard octane fuel has a significantly lower rating than ours (jungle juice ), but its defo still cheaper than what us mugs pay

Think you'll find our fuel octane rating is measured in RON which is research octane number, whilst over the pond it is MON motor octane number!

All this is, is the fuels ability to resist knock! With modern petrol engines compression ratios are higher than they used to be, a low RON fuel would detonate prior to the engines top dead centre or TDC. This causes the piston to decelerate very quickly and the engine would 'knock'.

So it is more important to use higher octane fuel (which is heavier as it contains less heptane) in turbo powered cars as the compression is much higher.

Modern ECU's can adjust ignition timing so as to avoid knock so most people will never hear it at all no matter what fuel they put in their tanks. The most important thing to have is decent fuel with detergents in it to keep the engine free of carbon deposits!

If you have a fixed engine map that requires you use super unleaded though, you may well experience knock if lower grade fuel is used!
