Just enquiring as to what type and make of fuel everyone tends to put in there cars.

When I had my S5 I used to put She'll Optimax (dear stuff) in it because if I used the cheaper stuff you could actually feel the engine pinking so now I have the VRS 220 tsi do I put the cheaper fuels in or do I carry on with the Shell Optimax .

I shall do a test on both to see if I can see any difference like I could on the Audi and will post back on here what I think.

My 63 plate TDi Vrs likes Shell Super Deisel, when my new 230 Tsi arrives it will drink Shell Super Petrol.

My current Audi S3 has Shell V-Power most of the time, if that's not availably any hi octane. When my VRS TDI 4x4 arrives it will have Shell, Ive ran previous diesel cars on supermarket fuel and in my opinion they all ran worse than on Shell fuel. 

When I had a Mk2 Fabia VRS it would misfire with most fuels so I had to use Shell vPower. My 220 didn't mind normal unleaded so in the 28k miles of ownership it ran on Tesco unleaded. My VRS 4x4 doesn't seem to mind Tesco diesel either so it'll run on that for the foreseeable

Bog standard ASDA fuel has been going into my 220 since I got it. Seems to run well so I couldn't justify the extra expense of a high octane or branded petrol.

 

My old Focus ST used to get Tesco 99 octane all the time because it was remapped and I could definitely feel (and hear) a difference when swapping to 95 octane. These premium fuels do have their place but the VRS doesn't seem to need it...

Shell vPower is most consistent, others varied too much with quality and additives.

Lewjo.how you finding the vrs 4x4

I don't believe the TDI version is programmed to take advantage of the higher octane fuel so you'll get sod all performance benefit.

Petrol is rated by its octane so the TDI versions performance would definitely be disappointing.

Slip of the digit I think?

Shell V Power. Because I've got money to burn.

 

 

 

 

 

 

But seriously, I find it does run better on it.

Tesco unleaded  or Sainsburys unleaded.

 

Tried Esso once and it felt a bit off but might be my imagination.....

I run mine on whatever I pass at the time of refuelling! Running a DTUK box too, and can't tell the difference at all between fill ups.

If you have money to burn, please give it to me as I can make better use of it, rather you burn it.

 

Thanks.

I'm finding my 1.4 TSI gives better economy on Asda fuel than standard Shell. Im sure V-Power might give an improvement but not really worth the money in my case.

Strictly V-Power, used it on my mapped Mk1 VRS and now my Mk3 VRS 220/300, which has been fed it from the day I collected it with 9 miles on the clock, never been contaminated with any other fuel.

It to is running a DTUK tuning box.

This is how my VRS Tdi DSG fares on Shell Regular Vs Premium (V-Power nitro ++++ super dooper rocket fuel advertising budget)

 

Notes:

1) I stopped working at the end of Feb so no daily commute through the city centre, journeys are now shorter but less traffic going to baby classes etc. during the day.

 

2) That Morrisons fill looks low but only one tank doesn't provide a good comparison

 

3) Figures are adjusted so that they reflect the performance of that tank of fuel. I previously used to fill everything in on one line meaning that mpg figures were for the previous tank.

 

4) I'm using mainly v-power at the moment in the hopes that it'll help keep the engine/dpf cleaner while I'm doing mainly short journeys

 

5) I'm not sure when the suppliers will have changed from winter to summer fuel mix

 

6) It's a VRS DSG. I spend some time in economy mode but usually knock it into sport when I'm pulling out of junctions or when I fancy a spirited drive.

Lol!

Money to burn I would not be at the skoda garage lol

Glad I can keep you all amused!

 

 

 

xdq  - I'm surprised at your mpg figures for a diesel. I'd have thought you should be getting more.

I've got 34.49mpg over 2,300 miles in my petrol DSG, and I don't hang about. A lot of pottering around too. Haven't done one of my 700 mile round trips from Cheshire to Kent yet either.

The 1.4 TSi DSG before it gave 41.52 over 15,000 with a best tank of 51.04mpg on one Kent trip.

I can't help feeling that all other things being equal (and I'll cover this aspect ) that there is a lot of 'placebo' effect in operation here regarding the claims for the benefits of one brand over another.

Just like America, we in Australia get a low standard but cheap 91 Octane fuel. It is mainly sourced from Singapore (or other Asian) refineries and is high in sulphur and goodness knows what else. Most of the Australian, Japanese and Korean manufacturers' vehicles can run on it but European vehicles demand the higher quality fuels with 95/98 Octane ratings and only 25% of the sulphur content.

The 'higher quality' fuel sulphur content still receives complaints from BMW and others saying it compromises the efficiencies of their engines sold here.

We can purchase a variety of different fuel types: 100% refined petroleum, E10, E85, refined diesel, or much more rare bio-diesel.

 

I have owned a 1.9D manual Octavia (no DPF) and my current 1.4tsi and used the recommended fuel for the car ie 100% refined diesel and 100% refined 95 Octane but I had no particular brand allegiance

My 'test' course has always been a 250km trip to see my daughter in the country which is relatively flat and free running.

I have never noted any difference in consumption that I could not attribute to external factors for either car. That included running several tanks of 98 Octane, also with no noticeable difference.

 

If British fuels from suppliers are varying so much in quality that there is discernable difference in mpg then surely a more accurate test could be performed in a laboratory for Octane and calorific value rather than the totally uncontrolled real world road environment?

 

I'll accept there could be differences in formulations concerning the detergents and their ability to 'cleanse' an engine but since  these additives are a dilution of the 'pure' product then theoretically they result in a lower calorific content. I'm no chemist but most advertising claims for most products are absolute BS.

 

I mentioned in other threads that I have re-acquired my daughter's 2003 1.3L Toyota Echo (since she has upgraded to a 2008 Mk5 VW Golf DSG6 ,and a really nice drive it is too)

and the Echo's user manual says with refreshing candour that its engine is designed to run on 91 Octane and while 95/98 Octane can be used, it is a waste of money and will not result in improved performance or consumption.

I thought USA calculate Octane slightly differently to us here in Europe.  So US apparently low RON fuel (isn't 87 their standard?) Is actually higher octane than European 95 RON.

US 87 is approximately UK 91 or 92

USA uses AKI anti knock index which based on the fuels RON and MON ratings which means it varies between 4 and 6 values lower.

I believed their 87 equalled out 91

Lewjo.how you finding the vrs 4x4

It's a nice enough car but I miss the 220, next time I'll be looking at a Golf R or Skoda equivalent of they decide to treat us. Diesel really isn't for me

Get a tuning box on it!
