I used the regaler gas and then ...the other time I was filling the tank, found out a sign saying premium fuel .

Premium only in your C43 my man. Shell V-Power is all I put in my tank.

My '99 C43 specifies 91 Octane or higher.

So while most brands have 3 grades (87, mid-grade 89, and either 92 or 93 octane premium), Sunoco (in NY anyway) has a 91 octane which is usually less expensive than all other premium-grade brands, and runs just fine for me.

What?

What kind of dishwater are you guys running your cars on? No wonder you're down on power..

Regular gas in the UK is 95 octane, with V-power/premium being 98/99 octane.

Mind you, I'd swap you for prices. The cheapest local place for premium (99 octane, 5% bioethanol) is currently over £1 a litre. That's roughly $9 for a UK gallon.

Or, to put another way, a fill up from close to empty, about $120....

Different rating system. Our 91 is the same as your 95ron. Our 93 is like your 97/98. However, even in L.A., its tough to find anything above 91 (your 95, remember).

They didn't offer 99ron when I was last in England so that part is interesting.

I put 89 octane with ethanol in my car because it was all the station had and I was on empty. It resulted in an immediate check engine light and now one of my oxy sensors is bad. So I would recommend against ehtanol blends.

I don't think it will necessarily destroy your oxy sensor, but I don't think the car liked it at all. 91 or better if I can find it is what I use.

BP did a trial run with 102 octane fuel, last year I think - it was hideously expensive (about £2.40/litre) and only at a handful of stations. I don't know if they're still selling it.
