Hi All

I'm due to collect my first Z4 this weekend (pics to follow), but first a question.

This may have been discussed before, but inspired by this article, is supermarket fuel likely to harm my engine? And would fuel additives combat this?

15p off a litre is difficult to ignore..

Cheers.
 
Well I've been using Sainsbury's for fuel for a while and it hasn't hurt my fuel economy or performance. Having just passed the 50,000 mile point in two years, my average is 38 mpg......

As far as I am aware, supermarkets do not own refineries, so they buy fuel from big oil companies that do.....

Ps hello and welcome to this wonderful forum, go on tell us about you and your Zed :thumbsup:
 
Yeah I'm aware they all get their fuel from the same place, but I was reading up on the additives that are supposedly not added to the supermarket fuel, or something. I've no idea to be honest :lol:

All being well, I get the car tomorrow - E85 3.0 manual.
 
Good luck for tomorrow, you probably wont sleep well tonight. When you got time introduce yourself in the newbies forum and post some pictures.
 
Hi, I have been reading the forum for ages and will be buying a Z4C soon, but your question made me sign up. Supermarket fuel is purchased on the 'spot' market. This is basically, the supermarket buyers purchase it from a wide range of sources, a lot of which is produced in Eastern Europe etc. This is not a problem but the spec maybe sightly relaxed.
The bigger difference is using 'super' unleaded vs unleaded. Super unleaded usually has, in the UK, up to 20% methanol. Again not an issue, in fact a great improvement. But if you don't use the car every day its a waste of money, as methanol will evaporate quicker than the other MOGAS components. Also it attracts water which causes the fuel to appear cloudy.
There is a water spec on MOGAS which is tested before the fuel can be sold, If you consider the amount of transfers the fuel must make before it makes it into your fuel tank the possibility of water contamination is quite high.
Production
Storage within refinery (separate components)
Storage within refinery (Final product)
(If coming from abroad) Ship Tanks
Road Tanker
Petrol station underground tanks
Your fuel tank.
Super Unleaded also stays in the forecourt tanks longer as it is less popular.
It's better fill up when the temp is lower as the fuel is a little more dense at low temperatures!

Fuel produced in the UK is better for your car, and your countries economy.

Do I use supermarket fuel??

Course I do its cheaper!!

And I drive a diesel at the moment!

Sorry for the rant and welcome.

Am I as boring as I think I am??
 
Interesting stuff :thumbsup:

So now I'll only be filling up on cold days and not going anywhere near to Sainburys, Tescos etc :P Which helps my Supermarket phobia no end :thumbsup:
