Car Fuel

[windermeregolfer]

This may seem a strange question - What is the difference between the quality of the fuel that the different petrol stations supply. 
Repsol are currently charging 1.115€ for premium diesel and DISA are charging 1.187€
Back in the UK I only use premium brand fuel, Shell or BP, as against Supermarket Fuel, whilst the price may be higher the additives do make a difference to and more than compensate in fuel economy, engine performance and protection.  The nerd I am I keep stats and can prove I  get 10%+ better economy from Premium Brand Fuel plus a very reliable car mechanic I use told me he would not service my vehicles if I used supermarket fuel.
Look forward to your replies

I think it's very difficult to determine the quality of fuel.  Here in the UK, premium petrol and diesel is very expensive - in my area it's typically £1.40 for premium petrol and £1.48 for premium diesel.  But the claims are that the premium fuel works better and protects the engine better.  I'm afraid I don't have the inclination to check mpg figures, but I do use premium petrol in my Porsche, but my diesel Freelander only gets treated to supermarket fuel!  The Freelander has done 70,000 miles on supermarket fuel and is still running fine.

Thanks Bedouin the difference I am looking to check is Repsol = to Asda / Tesco and DISA = to Shell / BP, I know I get 10%+ better economy with Premium Brand vs Supermarket which more than compensated for the price difference.


Standard vs premium fuel I can confirm based on a mistake in fueling in mainland Spain last month when I got 13% better economy with premium fuel in my RR Sport 2018MY

You really are a proper nerd, John  

I understand you do love your car but this is over the top. At least for somebody who use a car just to get from point A to point B.

...I'll get my coat.

With you on that one Sam. My friends & family go on about BMW this & Land Rover that. To me it’s 4 wheels & saves the legs & that’s it. Car salesmen will never get rich off me

It is the Land Rover technology and apps you get to support you that give you the info

Let's hope your App/data is more reliable than VW's emissions data!

I think so, Which (Consumer Ass.) did a report 3 or 4 months ago on the dirtiest diesel cars and none of the Land Rover models  were listed.  I do know that in the last couple of months delivery of new vehicles has been delayed by up to a month due to extra tests to comply with latest EU regs, so they clamping down on data.

It’s funny but with hire cars in Fuerteventura the hire company generally ask you to refuel with the lower grade fuel either diesel or petrol.

As far as I know the more expensive petrol ie 98 is only required if your driving something with a high performance engine like a Maserati, a waste of time buying it for a Clio. The diesel thing just doesn’t make any sense at all. All diesel has to comply to a minimum standard and a low sulphur content. 
As far as supermarket fuel in Ireland or the U.K. its purchasing power and individual margins that dictates the price. It all comes from the same tanks.  
Most people of our age are thinking back to the days of regular or premium petrol where additives stoped cars from “pinkin”. Remember the cortina running on after you switched it off. When unleaded arrived all new cars were eventually tuned to run happily on it.
