Re: Diesel Engines and Supermarket Fuel

Used to run the Mazda on that smelt like a chippy when on tickover, would not put it near a dci though.

Who would design a vehicle that falls over when you stop?

If you find a fix for your problem please let us know it will help others.

Re: Diesel Engines and Supermarket Fuel

Never had a problem with supermarket fuel, they have to supply fuel at a specified standard which meet the same standard as the mainstream garages. A friend who has a relative says that some of the fuel comes from the same bulk store anyway and it's sold to the stores at the same price as the big names.

The only time I did have a problem was from a main brand and I was one of about a dozen drivers who had the same problem of contaminated fuel from the same tank. The supplier paid for the fuel service on my car as it was proven that it came from them.

I certainly wouldn't run my dci on veg oil .

What I do is put a bottle of fuel system cleaner in every 10000 miles (every oil change) or so which cleans the injectors and other components and generally I get 1-2 mpg improvement for a while.

Re: Diesel Engines and Supermarket Fuel

All fuel sold has a standard marked on the pump. Supermarkets sell fuel at minimal profit to encourage customers on site. The 'supermarket fuel' story is encouraged by the oil companies to make people think they're buying better fuel at their sites. Car manufacturers always blame someone or something else. |And they always claim never to have seen it before.

Re: Diesel Engines and Supermarket Fuel

I have used both supermarket petrol and now diesel with no problems. I had the Meg for nearly 8 years, almost all the time filling up at the supermarket, no problems. Likewise with the Scenic, coming up to 18 months now

Re: Diesel Engines and Supermarket Fuel

Funny I should come across this and how they try to blame anything..

My Mums partner owns a 2011 Renault Scenic 1.5DCi.

Its only done 14k as its just used mainly for shopping etc and that as only EVER had Shell fuel put in it as that fuel station is just down the road from them...

Yesterday while going to visit his Brother it started to cough and then came to an halt. RAC man came out and connected it up to a diagnostic and it came back as injectors

Renault today have confirmed that it does need a couple of injectors, and at 14k too

I was always led to believe that supermarket fuel cam from the same refinery as Shell etc anyway??
