Super Unleaded (Shell vs Texaco)
#1
Just being curious, but does anyone know the difference (e.g. RON value) between Texaco's "Super Plus Unleaded" and Shell's "Super Unleaded" fuels? In my area there's a 4p per litre difference in their price.

A recent article in the Daily Telegraph Saturday Motoring section said that Shell fuels had a higher RON value than other garages.
Something like .7 or .8 of a RON higher.

The local BP station advertises 98RON on the pump handle of the Super Unleaded - I am not sure how realsitic this is (everywhere else is 97?) - is there anyform of law that means the fuel HAS to be 98 RON or more?
If I am using 98RON and Millers Octane Plus then I have a nice WRX Sti loving 100RON!

Tried Texaco the other night... definately not as good as BP or Shell which is all I run my P+J on nowadays....
Except Seca 99+ Ron Super which I found in Belgium on Monday perhaps we should beg and plead for them to open up branches in the UK.

Last week I posted about a high idle speed!
I filled up when very low at clacket lane services with ELF super plus, by the time I had got home 50+ miles it was running real rough, and the idle speed was at 1500 rpm.
I was going to look at the cold start valve, (thanks ransj) but after two tank fulls of shell it was back down at 800 rpm and running sweet as a nut.
Could the ELF fuel have been doggy or actually half fat unleaded, but from a full fat pump, and could this have been the cause of my probs.

Interesting to hear everyone's response to my question.
I rarely use SUL (just run around on boring old UL), but I did use Shell SUL a few weeks ago for a track evening (let the car run on fumes, then add a quarter tank of SUL, let it run on fumes, then a full tank of SUL... none of this reset jibberish).
Verdict - IMHO it's good stuff. On the track I'd certainly picked up some more power/speed. Recently I've been using slicks which have a 5% smaller rolling radius than standard tyres. On the exit from the hairpin (at Knockhill), then gunning it up the straight I used to have real trouble keeping pace with UK "standard" scoobys. This time - no trouble at all (in fact I was gaining on them).
BP SUL and the likes may be better, but at 4p cheaper per litre Shell has my vote.
