Filling up with Petrol

Greenday · Post by **Greenday** » Thu Mar 20, 2003 11:57 pm

When i go to fill the CC up with petrol i have to hold the pump horizontal or it stops eveytime i squeeze the trigger fully, is there some method of putting the pump in correctly or do you just have to live with holding it at that funny angle?

I only get this at Tesco's filling station,if I go to asda I have no problems .... I try to usually lift the pump up and out slightly, sometimes does the trick, otherwise I look like a

taking 10mins to fill the car up :rolleyes:

I mainly go to Tesco so maybe the answer is to try other petrol stations then, do Asda pumps fit in really easily?

From the other side of the world.... I totally agree with Erm. It's the same here in Australia.

Has anyone here ever got stung on a night out for high priced watered down drinks?

YOU ONLY GET WHAT YOU PAY FOR. Don't cut corners. Go to the major oil companies for your products and you'll get what you think you're paying for. Also, ONLY use premium unleaded in your CC - do otherwise and you will have warranty problems.

Pay a bit more at the pump and I guarantee you you'll be better off in the long run. As for oil - do the same - full synthetic all the way.

You might think you've done a great deal on a tank of fuel or a sump full of oil but believe me I know that using crap stuff in either will take its toll. Next time you top up fluids, balance it against what you paid for the car - you'll see that cutting corners just doesn't add up versus the potential downaside of bad fuel and wear and tear from crappy oil.

ps this message wasn't sponsored by an oil company! I worked for Exxon/Esso for 12 years and know the deal!

Err well that may be so, but I bet that the premium unleaded doesn't cost Â£0.95 per litre in Australia (AUD 2.50 per litre, AUD 11.40 per gallon)

Think I will stick to the cheap supermarket stuff, because unless its high octane you won't notice any performance difference and as I do not plan on keeping my cc for 10 years it would mean that I was paying for the next owners use!!

So .. what are we saying here ... I go to tesco whcih are supplied by Texaco ... but then I go to a Texeco garage and pay a few pence more per litre because of the location of the garage and its extra running costs and Im actually not really getting the same kind of petrol

:

and yes, Im keeping this car Max 3 years cos the warranty runs out and it would need an MOT, err and I like the smell of new cars

there is a reason why supermarkets have cheaper fuel.......

:rolleyes: :rolleyes: :rolleyes: :rolleyes: :rolleyes:

never fill up at a supermarket..... ur car will idle like a pig with supermaket fuel compared to petrol from esso

your not really winning the argument yet Erm, please be a little more scientific with the differences please.

Greenday · Post by **Greenday** » Fri Mar 21, 2003 1:08 pm

I never knew there was a difference but as Andrew said if you can tell what the difference is i'd be really grateful

You might like to have a look at

http://members.tripod.com/~miniwww/gasoline.htm

which will give you some idea of what goes into petrol and hence the variables that can be twicked.

Having had a look round I can't find any proof (other than "a mate told me") that what texaco sell to Tesco is the same/different you get on a Texaco forecourt. Markets would make me belive there is a difference (just like Tesco's cheap beans taste different from Heinz even if it is heinz that makes them).

Perhaps another way of thinking about it would be that all petrol has to meet a certain level and manufactures make their cars to run on that level. That's not to say it won't run better on a brand name fuel but you you should get a certain "level of service" from a cheaper fuel.

At the end of the day it would seem sensible for everyone to give it a try and swap to the other side for once and see if they notice the difference. I always use Tesco's but I may swap to a named brand for a couple of tanks and see if I notice a difference.

I just did a quick search for best Puegeot fuel and did find (but again, it's all hearsay).....

http://www.bba-reman.com/auto-mine/peug ... oblems.htm

Poor Running :
General poor engine performance / sluggish response / Flat spots, UK based GTI's more prone than
other models.
Fix : This one may be just a change of petrol, believe it or not my newsgroup contacts have
indicated which petrol they find Peugeot engines run best on, top marks went to Texaco, BP and
Sainsbury's, worst Esso and Shell, Esso is a recommended lubricant supplier!!. Super Unleaded
works well for some, but why pay more, ask your dealer to pay the extra!

Is there supposed to be any difference between people like Esso and BP or is it just between normal and supermarket petrol stations?

samwise · Post by **samwise** » Fri Mar 21, 2003 2:29 pm

Again, I would have to believe yes as petrol is such a complex thing that you can pretty much bet that one company will have a different make up then others. Here's an example make up from the site I quoted .....

15% n-paraffins RON MON BP d AIT
n-butane 113 : 114 : -0.5: gas : 370

n-octane -18 : -16 : 126 : 0.703 : 220
( you would not want to have the following alkanes in gasoline,
so you would never blend kerosine with gasoline )

in gasoline, but have some of the highest blending octanes )

Anyone other than a chemist has probably now gone to sleep. Cheers

So it really is just a case of trying out different petrols

Erm · Post by **Erm** » Fri Mar 21, 2003 3:24 pm

well let me put it this way........ if u want all the chemical bullshite i cud give u that but it'll put u to sleep but the biggest difference is just the feel of the engine........

supermarket fuel makes ur engine feel all lumpy and sluggish whereas esso or BP or shell fuel makes ur engine run smoother.....its a well known fact that supermaket fuel is cheap and nasty stuff thats more watered down than mcdonalds coke
