Just wondering how supermarket diesel fares in the 1.9 130pd superb engine? Any tips?

It is just go go juice and you need it to run the car, its only diesel & in the UK it will be pretty good at the minimum quality.

It all comes out a refinery in a tanker,

and retailers some add additives and cleaners and some do not. Sometimes it is best to avoid the additives, the car will have run on anything up to now,

it is not a new engine

Try different retailers and Standard or Performance diesel and you decide is the best way to go.

The specified fuel is EN590. Supermarkets sell fuel to this specification - I use it all the time in my PD without any problems.

I used to test diesel engines and fuel for a living. Diesels are very tolerant of fuel variation as long as a minimum Cetane value is observed - included in the EN590 test. Fuel lubricity is not a critical factor in the oil-lubricated PD fuel system.

I look after an old diesel Peugeot with a Bosch VE rotary pump - 173k miles and no problems. Tesco fuel all the way.

Far more important is clean fuel without any water in it. Supermarkets sell a lot of fuel and generally have very clean tanks. Change your fuel filter for a Bosch or M&H genuine replacement every 30k miles. Don't fit Chinese elements from VAG or anyone else.

I use it all th time . Even go a couple of miles extra as the price makes it worthwhile if I buy a lot .Never noticed any difference in performance between Supermarket & normal places

As already said.

EN590.

As has been said, the basic fuel is the same. The difference is what additives the supermarkets add. In general most don't seem to add a diesel anti-foaming agent, or as much or even none of the anti-smoke or injector cleaners.

You pays your money, you takes your choice.

Personally I have found that using Tesco diesel I get on average 10% worse fuel consumption, and it seems not to pick-up as cleanly. Therefore I stick to BP or Texaco as they are convenient.

My 1999 MK1 TDI has always run on Tesco diesel without any problems. Some big brand 'power diesel' give a small boost in mpg/performance but it's not cost effective. The ONLY improvement in cost effectiveness comes from using Tesco diesel and 2EHN at 3cc/45l. Using more, is just throwing money away - even though some branded cetane boosters claim otherwise.

Another here that uses supermarket fuel when ever possible. Never notice any difference when I do fill up with branded stuff.

Interesting that the " never put anything but super juice" in my precious baby haven't hijacked this thread yet!!!

Tesco's all the way here. Never noticed any difference whatever diesel goes in any of ours.

These guys are right, although a few years ago Morrison's fuel went outside of EN590 spec (too much biodiesel component) and they had to remove the standards label from their forecourts. Probably not a worry for most people, but in PD engines which in many cases specifically say "do not use biodiesel" in the handbook, possibly best avoided. I've used tons of Tesco in the past when they were the cheapest in my area and had no problems, I'm back on Shell at the moment simply because it's the same price and on my way home from work, and it runs exactly the same.

I always use supermarket fuels, usually Morrisons or Asda and have never experienced any trouble with either, being a tight Scot, it's all down to price for me. As already mentioned it meets the spec!

In the last four years I have been driving works vehicles (all VW Group PD engined) and done around 250K miles using the same stuff, again, no probs at all.

Is my vRS a fussy one then? Iv used supermarket fuel since i started driving, even in my 150PD Golf and it never bothered any other of my cars. Bought the vRS and continued to fill up at Tesco ect it was getting rubbish MPG, to the point of returning 34mpg on 30mile + trips. Had the injectors changed (on recall) so i thought this would sort the problem and hoped it would get better, it did but was only managing a max of 39mpg.

Started to use fuel save by Shell and it seems like to like, i do alot of varied driving, lots of urban and lots of twisty, hilly moor driving and MPG increased after about 3 tanks, it will average 45-48mpg on a quick run and have seen 55+mpg a few times aswell

I use Tesco or Shell whichever is the cheapest, this car has done 6000 miles so far and I can't notice any difference

In 15,000 miles the only difference I've noticed between supermarket fuel and "branded" is the price.

Can't say I've seen any change in mpg, smoke or anything really.

If your engine is already clean you won't fine a great difference between Quality fuel and Supermarket fuel

Once the quality stuff has started to cleaned your engine, you will notice a difference, It won't do it overnight, a few tankfuls are needed.

I think

If I eat Tesco Value sausages, I am fuelled up.

If I eat Waitrose Pork & Apple sausages, I am fuelled up.

My car views it the same. As long as it's diesel, she'll drink it. Parsimoniously.

but the Waitrose sausages will be of better quality, i.e. less fat and more meat than the Tesco Value Sausages. there for the Waitrose ones are better, just like fuel, Quality verses Rubbish

Most of those sausages will mean you end up with clogged arteries whatever the class of supermarket that sells them,

but we all die anyway.

Which comes back to Supermarkets to fuel your car.

Lots of those Diesels viehcles will run on Cooking oil right off the supermarket or cash and carry shelf at prices from 80-100 pence a litre or more.

Obviously that might also clog its filters and gum things up like that sausage fat,

but then for some cars its just a bit of modifying and a heater, twin tank & some filters.

Diesel is not some Magic Go Go Juice, its just the convenient one with Duty/Tax and VAT on that.

**Public announcement, dont go pouring Cooking Oil into your 1.9 130PD's tank*

Private use, 2500 litres of ('Used') Oil annually,

& check out the ins and outs with the HMRC sites & forums and you can save money.

Personally speaking, standing pouring gallons of Oil in a vehicles fuel tank is a PITA,

& a Filling station even if a down market (non Waitrose/Shell/BP/Esso/) one is one of lifes little luxuries.

I've used nothing but Tesco diesel for 6 years in my L&K 130. Never been a problem. The stopwatch says it still has all it's horses, worst town driving still gives 45mpg.

dont supermarkets add bio diesel to the mix? to bring the price down?

All diesel now contains 5% bio diesel.

Wouldt this effect older diesels? When was bio diesel introduced. I dont know alot about this stuff, obviously

Future legal requirements for biofuels

Currently fuel companies are permitted and, from 2010, will be legally obliged to mix five per cent bioethanol with 95 per cent petrol and five per cent biodiesel with 95 per cent conventional diesel. Mixes at these levels will not do any damage to fuel systems, nor require any adjustments, and will be a standard ingredient of the fuel. Renault and Peugeot-Citroen are now offering some of their vehicles with the ability to use B30 - a 30 per cent biodiesel/70 per cent conventional diesel mix.

deemed to be safe at 5% rate. Has been the case for a couple of years now I think

Here is VAGs UK biodiesel statement
