Technical Does anyone use supermarket petrol?

I always used to fill up at shell, but now im at uni the nearest shell station is 10miles out of my way so i just end up getting tescos petrol.. havn't had a problem yet but my car doesnt seem to run as well on it. It runs so much better on shell fuel and gives much better mpg on the return 180miles back to uni.
 
I wont use Shell now because I had my card cloned in one of them, and all the stations around here have had bad reports of that.
hahaha same story here!! the three cheeky little sri lankans doing it also got 1000 people in a fortnight!! after they got dun for that they moved onto the next scam, people paying cash and not asking for a reciept then the little tresures pocket the money and report the paying customer for drive offs!! fantastic!! my car runs fine on tank of morrisons every week!! just a question tho, went to pumps other nite and put in a tenner and it said 11 something litres but it only made my fuel gauge in car move half as far as normal asif id just put fiver in it. do they have to calibrate the machines?

I admire your restraint. I think they have been a little more than Cheeky!
I wonder what happens to these types when they're caught?
 
My dad has a pay as you go electricity meter, so for years he topped his card up at the petrol station.

Well one day the electricity provider sent a letter saying see you in court you have not topped up your electricity card for 2 years therefore you are stealing our electricity somehow.

Turned out the petrol station was keeping the money and somehow tricking the system into topping up my dads electricity card.
 
YYYU Petroleum? - are they a subsidiary of one of the Big 5?

Given the `exchange agreement’ (whereby a tanker can draw-off supplies from a competitor’s refinery) then, as Honest John (Telegraph/motoring, Sat 21 Feb 2009) points out ...

On some occasions you’ll be lucky with 95 Ron supermarket petrol, on others you won’t. It depends where it has come from on that particular day. If in doubt, you can always use Tesco’s part-bio 99 Ron fuel. Telegraph/motoring 2009/02/21

… and your local Tesco could be supplied by Kingsbury (BP?) & your local Morrison’s by ConocoPhillips one day - & vice-versa another day. I’ve heard it argued that Sainbury’s are exclusively supplied by BP – but again, given the exchange agreement, that’s no guarantee that the tanker in BP livery has BP refined fuel on-board. The supermarket bulk tank could therefore contain a variable blend of (say) 95 Ron from two (or more) refineries – for example 10% of the dregs from last weeks supply from Kingsbury, & topped-up with 90% this week from ConocoPhillips. Fatal to that is (of course) the exclusive supplies of high octane e.g. Tesco 99.
 
Seems like ages since I've been on here. Anyway.......I've been using Shell V-Power.

Results:
1. £29.01 @ 89.9p/l (32.26 Litres) - 257.5 miles to a tank
2. £31.95 @ 98.9p/l (32.30 Litres) - 266.2 miles to a tank
3. £37.60 @ 96.9p/l (38.80 Litres) - 371.3 miles to a tank

Last week I was amazed how well the petrol did, I couldn't believe I did 370 miles to a tank!!! Just done 200 miles and my tank is nearly full, just hoping I get even more miles this time.

The car wasn't sent away to be cleaned, it was cleaned where I had the MOT done. (My mistake!)
 
I remember some years back when I watched Fifth Gear, they explored this issue. The only difference they've found from Supermarket and Branded fuel is that the latter does indeed works better for high performance cars, such as Golf GTIs. Nothing much differs for cheaper cars.;)
 
That article on 5th gear was about higher octane fuels making your car produce more power, rather than the quality of fuel pump to pump.

Your right though, only big engined turbos made any sort of gain running on optimax etc.

Hi again David - I'm not sure I'm reading your figures right(?). Your first row refers to your 95RON Morrison's fuel? - and 2&3 are your Shell fills. Do you mean that when you topped-up with 38.80L, you'd covered 371.3 miles on the previous fuel fill ... if I've got that right(?) ... e.g. when you top-up at the forecourt, then you haven't (as yet) done any mileage on that fill.
 
One other thing I don't think your taking into consideration is crossovers when delivering fuel to the tanks.

I've worked in quite a few petrol stations during uni, from sainsburies to your local bob filling station.

All the major petrol stations have a no cross over policy, this means if there is a cross over of desel to petrol or vice versa they will stop using that tank, pump the entire thing out and send it back for reproccessing at thier expence.

However alot of the supermarkets when a cross over happens "assess the situation" and then decide what to do.

If it's only a minor cross over, i.e. only 100 litres etc they will attemp to top the entire tank up to dilute this mix

If it's a major one they will normally pump the tank out but then re-drop the fuel at several other stations to dilute it out. Meaning other stations can also be effected this this contaminated fuel.

From all the petrol stations I've worked in I came to the conclution of either Shell or BP.

Although when I worked at sainburies they were using BP fuel and I believe they still do.

Number 1 was mixed fuel. I filled up when the tank was nearly empty with V-Shell.
2 and 3 were using V-Shell.
Yes your right about the 38.80L bit.

By the way, I reset the trip computer? to zero when the fuel is halfway (measuring it on a flat road) and mark it down on a computer program. Thats the way I measure the fuel.
