Dirty Petrol

[imamosher]

as I understand it all the companies including supermarkets use the same tanker, however when the tanker arrives the larger companies ie shell, bp etc syphon the petrol off first.....the remaining petrol is what the supermarkets take and is cheaper as during transportation the impurities and sediments have sunk to te bottom and therefore the petrol on the top is the cleanest.

this is what i have been told...not sure if true or not?

seems to make sense.

Just talking with a friend of my misses there and she is a petrol station owner/manager (A supermarket one, wont say which). Got talking about our new car we have on order, after a long conversation about this and that, she mentioned that for petrol we need to stay away from supermarket petrol and only goto Esso, Shell, BP stations. Asked her why ?

The tankers that the supermarket stations use are often very dirty, the supermarkets do not add additives to their fuel either and hence are not very good quality at all. Shell etc all use clean tankers, clean fuel and is of a much better quality.

I had never given this much of a thought before. Anyone else heard this ? I wouldnt want to be putting dirty fuel into my GTI.

I don't know what station she works for but I worked in a Tesco petrol station for 3 years and can comfirm that in the south west the same fuel that goes to BP, Esso and Tesco. It all comes out of the same depo. Our delivery sheets have BP Esso and Tesco at the top. There used to be a time where the additivs were put in by Tesco but this has stopped.

Fact: There are several filters petrol/diesel has to pass through before it is despenced, so what ever comes out of the pump is clean and not full of gunk. We shut down our pumps if the tank level falls below 10%, 6 tanks at 44,000L each so the customer dosn't get any of the gunk. It is also filtered out by an external company every year or so.

Cool, ta for the info, as I say I was just passing on what I heard.

FYI R32UK, the MK6 GTI engine is designed to run on 95 RON so if I had a MK6 id save the money and stick to 95.

Although If I had a MK6 Id get it remapped and then have to use the 99 stuff lol

Tried this test on the R32 and found it made very very little or no difference Alan. however on the mk6 is seems to have a much bigger impact despite what it says on the petrol cap.

This if course is just what i have noticed using my own testing methods (bit pants really) but I suggest you try it yourself before making a judgement

Every, and i mean every, car i've owned (from Ford Ka, Sabb 900 runarounds to numerous BMWs, Mercs and Porsches) that i've run on both VPower/Optimax and normal 95RON has given the same results for me. That is, 10% extra  mpg on VPower/Optimax. Well worth the extra 6% in price to my mind.

Even the GFs Fiat Panda 1.2 feels decidely perkier on superunleaded, even becoming fun on the back lanes !

This weekend i was away and had to use cheaper grades from quiet garages in rural locations, and over the last 150miles have definately been able to tell the difference!! most probably down to what you say and the slightly lower rating

What was the actual difference you noticed?

Rolfe.

slightly lower mpg.. about 2-4mpg I would say at a guess. Felt a little slower to respond at full throttle and low revs high gear. Quite strange but definately felt like it was working batter with the better fuel.

Interesting results R32UK.
