Has anyone used this in their 1.6?  I put £15 in (by accident) but could not help notice how smoother and quieter the car felt.  I just hope it has casued no damage

Unlikely to cause damage.

Good idea to keep on using it and see if the car continues to be smoother and if you get any better economy as well.

 

Whos was it, Shell V-Power or some other Brand?

Not 100% sure but think it was Texaco   Will look next time I use that garage it is not my usual

It won't harm it at all. It's an extra benefit for the diesel [emoji106]

My tank is never full, I just add £10 or so now and again may just add the odd £10's worth now and then.   I did notice I never had a regen asked for for quite some time since adding the superdiesel

I usually fill up when it gets near to half, almost always at Asda. How much more than ordinary diesel. At the moment it's 115.7 Pr litre. Is it O.K to use with,say 1/2 a tank of regular stuff?

It won't do your car any harm - I've read loads of stuff on the super petrols and diesels and I've come to the conclusion that the main benefit is that it contains more detergents to help keep your engine cleaner and hopefully last a bit longer. Maybe the cleaning out of the crap that was in the engine is what gives some users the better throttle response and MPG. And maybe some of the people who have people claimed better MPG could just have driven slightly differently during the use of that particular tank of petrol/diesel?

 

It's been a while since I used any of the V-Power etc fuels so I'm going to try a tank of Tesco Momentum and see if it makes any difference, plus I still get my points and 4p off a litre. Let the games begin :clap:

 

 

You'd be surprised at exactly how crap a grade of fuel you can use before it has any effect on the engine

I've just had a look at what it says in the owners manual, & that's not much.Only use diesel fuel that meets the EN 590 standard. Then it says in the cold season use only"Winter grade diesel fuel" What's that when it's at home? How much more expensive is it?

 winter diesel has an additive included to help stop waxing up in frosty conditions, it is automatically put in at the refinery,

I haven't tried it in my new Yeti as yet because the dealer "gave" me a full tank on collection. However I have to say both my Tiguan 2.0 DSG ran more smoothly, quieter, brisker acceleration and more economical on Superdiesel.

I find exactly the same with my wife's new Peugeot 2006 1.6e HDI.

OK it's more expensive but the better economy negates alot of the greater expense.

The first time I put it in my VW my wife asked what I had done to it! Even she noticed it! (I hope she doesn't read this post!)

Or not - SWMBO used to work near TESCO, filled the (diesel) car there all the time - it ran like a concrete mixer unless I threw STP or similar in every week.  Now she works elsewhere and fills up at BP on the way (standard fuel - not super) - we now have a smooth JTD FIAT -something I thought didn't exist.

I thought all diesels ran like concrete mixers?

Camelspyyder makes a very valid point about many "supermarket brand" fuels..... I go back to the days when I had a Citroen Dyane and had never had any bother at all starting it. After about a week of very difficult starting, I contacted a friend who specialised in "twin pot" Citroens. Straight away he tasked where I bought my fuel and told him it was from a particular supermarket. He told me to fill up brim full with a major brand to dilute the other brand and it worked! Another friend with a small 1.0 ltr Peugeot said she was selling it as she had so much trouble starting it... I told her the advice I'd been given, which she followed and no further problems.

Some say it's all from the same refinery and there's no difference...... For the sake of say a penny per litre, which equates to about 60p a full tank on an average car, which you paid thousands of pounds for, why not but "branded fuel"?

The "Superdiesel" debate re advantages vs cost I might never win, but I find my cars run better as I posted earlier. So if it's available I use it.... Why not try it say every third fill as has been said earlier it keeps your engine cleaner?

The Dyane was a 2CV no? My previous statement was regarding modern petrol engines that they can take some pretty ****e stuff before beginning to show rough usage.

Thanks for the replies.  I was told years ago about supermarked fuels but took no notice but since moving to Lancs have only ever used "proper" garage fuels.  There has been a difference and that includes an old Honda civic I had before the Skoda.  I was never too sure if this was because I havew a new(ish) car or my first time with diesel. 

Re the superdiesel I rare fill up my car and tend to put in £10 worth when it needs some or dor a top up (half full on gague) I from now on will drive the extra mile or so to use superdiesel.

I realise this is a super diesel thread, however, I have a 1.2 tsi and I tend to put tesco super unleaded in (other super markets are available but tesco have a shop and save offer so I'm often getting 6p off a litre, bringing it to the price of their normal fuel!). What I'm finding is my economy is better with their super unleaded than shell's normal grade fuel which I would put in if not using the tesco super. I've read loads of mixed threads saying it does and doesn't make a difference to performance and I have to say I'm not really sure if the super unleaded does but as previously said its not loads more per litre and I do see a better return on miles. It's not like I'm driving a high performance car!

Always been wary of "Super" fuels since Shell's 1986 effort Formula Shell (claimed to clean your engine) which blew up most astras and cavaliers it came into contact with.

 

I didn't drive a Vauxhall at the time

I think in "Formula Shell" they used an additive which caused major problems as you suggested. I seemed to remember that Honda started to refuse warranty claims and tried to get customers to claim from Shell!

However I think the R & D departments do alot more research nowadays and we needn't worry.

Strangely, Formula Shell only blew up cars in 4 countries worldwide.  Clearly their product was not produced consistently.

£1.25 pr litre at my local Co-op/Texaco station. The guy there told me that a lot of taxi drivers fill up with it.

I use the Shell V Power stuff in my TSI Rapid cos Honest John recommends it , don't know if it makes any difference though . I can afford it because I do very few miles so the cost of fuel is not a big deal to me .

Hi, I've lurked since buying my Spaceback 1.6 in Nov 14

I've always put ordinary diesel in and been happy with the performance. After reading this thread I put in a tank of super diesel. I immediately noticed the engine was a lot quieter but I didn't see any increase in mpg. At the next tank fill I went back to ordinary.

I had though by the end of the super tank began to notice increase in avg mpg. By the end of this second tank (ordinary) I've seen huge increases which must be a legacy from the super fill?

My usual 20ml trip to shopping in Dumfries usually returned approx 68 mpg. My trip this week, all be it with heavy traffic so never got much above 50mph, includes 5ml of urban 15 rural retuned over 80mpg. I'm well pleased with that.

As there are numerous factors affecting fuel consumption apart from the fuel itself, I believe it is difficult to keep all other factors constant between two refills in order to compare. Especially when the expected difference is rather small, in the order of few percents.

With that in mind, I would say that you should keep refueling with super diesel for at least one year (to average ALL consumpion factors) and then compare with the previous year, in order to reach a safe conclusion. And don't forget to take the higher price per gallon into account!

Sort of right, but thre sre circumstances where you may use the car consistently e.g. I ive near J4 of the m5(Nromsgrove) - about 3 miles up the dual carriaeway. I used to work a coule of miles from J2 of the M54, so my journey each day was M5, M6, M54 and back - near enough dead-on 30 miles. so in a (petrol) cavalier I was ideally placed to get consistent running and consistent fuel consumption across a 3 - 4 week period. NB I had to fill up every 8 days, empty to brim! I suspect with the Diesel Rapid I have now I would be filling up every 14 days!
