I get my Rapid Spaceback on friday and was wondering what fuel people put in their 1.2 110 cars? Is 95 ok or should i stick Tesco momentum in it?

Complete waste of money putting high octane fuel in a little 1.2.

Momentum and other high performance fuels are designed for high performance engines (for example, used to use Momentum in my 200hp 2.5L KV6 Rover 75 (remapped to squeeze the extra 10hp out of it). You'll get and see no benefit from it in a low-performance engine such as the 1.2TSI. Normal 95RON unleaded is what it is designed to run and most importantly, what it has been tuned for. Normal unleaded petrol will deliver the most appropriate results in terms of performance, engine wear and fuel economy.

Currently trying Shell and Shell V-Power Nitro+ alternately in my 1.2/105 -  difference is 3 to 4 mpg, but it doesn't drive any different.  I don't think its worth the extra money over Shell 95.  6 to 8% more miles for 10% more money.

 

And there's a Shell 1/2 mile from Tesco so they pricematch each other - If I wanted to keep using premium fuel I'd stick with Shell - Tesco Fuels were awful in my other car.

Cheers thats all i needed to know If its designed to use 95 then thats good enough for me. Ill start low and get used to it first and maybe try a different fuel. I do normally use Tesco fuel but could change to Shell as like you they price match near me.

I use Shell wherever possible, but not Optimax V Power + Nitro Sexy Time. Does the 1.2 TSI even adjust itself to take advantage of the extra compressability that 98/99 octane fuel delivers?

I don't know, but it does always do 3-4 more mpg from a cold start over the 1st 10 miles of my daily trip

Shell V-Power Nitro+ & Tesco Momentum 99 in the UK are both 99 ron Minimum.

'Greenergy' Produces the Momentum and they bring the Stock Fuel into the UK at some of the same Facilities as Royal Dutch Shell.

Both have Secret Detergents. (sodium).   Shell V-Power Nitro+ can be 100 & 102 Ron in different countries on Mainland Europe.

 

The other UK Super Unleaded from ESSO, Sainsburys, BP are 97 ron Minimum.

'Greenergy' are supplying ESSO Filling Stations in Scotland and other areas of the UK with 'ESSO Quality Fuels' Unleaded, Super & Diesel.

& other Retailers.

 

You never know what you are getting from who, but you are getting the required grade, and Minimum Octane & maybe you do not need the 

Detergents.

Tried v power in mine and made no difference at all. It bogged down more with it in. Just used normal Shell as I do now.

I have a 1.2 110 PS Toledo in which I use 95 RON which seems fine.

I normally use 95RON from wherever is cheapest and convienient (mostly Tesco/Sainsburys who face each other in Kings Lynn and so are fiercely competetive) and this is absolutely fine in my 1.2 105. I'm returning average 45.5 or 46 mpg.

 

The car ticked over to 6000 miles over Christmas so I treated it to a tank full of 98 RON Shell V-Power. My rationale being the extra detergents just to give the fuel system a clean through. The car did seem to have a bit more pick up and response and I saw the average mpg rise to about 47.6-48 mpg. 

 

Being a rational professionally-registered engineer, my opinion is that there are marginal gains but it makes no economic sense to use 98 RON. In terms of mechanical sympathy, just like most other cars I've owned, I'll buy an occasional tank full of high octane fuel with detergents to potentially help things run a bit smoother between services (because it won't do any harm), but ordinarily 95 RON is perfectly fine.

I'd be wary of using Tesco Momentum. Greenergy, as the name suggests, use a lot of bio-ethanol in the fuel. More so in the 99 as its an octane booster. They sell it as a positive environmental thing, however, it is not particularly good for your engine.

Are you wary and have never used it?

 

It is lovely if you want 99 ron minimum, and particularly good for 1.4 TSI Twinchargers, why so many with them use it.

& these are not the ones with the failing engines, they are running 95 & 97 Ron usually.

The Shell V-Power Nitro + formulation is not easy to find, the spec Of Tesco Momentum is clearly set out for anyone that wants to know what it contains.

I have used it, but do not any more. There is a lot written about what ethanol does regarding corroding engine components, which is why there are legal limits as to how much they can put in (however they don't legally have to tell you in the UK), which is why I stopped. Its a straight no for any old vehicles as it will eat through the materials used in pipes and fuel pumps.

 

It also has a lower calorific value than petrol and is hygroscopic so increases the moisture in your tank.

 

I do agree that we don't know whats in V-Power, but at worst I expect its as bad as Momentum (which I expect to be on the legal limit, do you have an official figure for it?), but likely better as Shell are in the business of pumping oil and Greenergy make ethanol.

Edited 13 January, 201610 yr by Huskoda

Why we get the Winter Spec fuel is in the UK Oct/Nov to March because it is less hygroscopic.

As to not using it from Tesco (Greenergy), then thats a good choice for you, others disagree obviously because of the proven benefits easily proven in the real world by using it like on the 1/4 mile track and confirmed on dynos.

Personally i have a switchable map and the different octanes are easy to check.

(For special occasions i buy 102 Octane Hiperflo 250 @ £69 for 25 Litres.)

Running on Mainland Europe where higher Octane Shell V-Power Nitro+ and other fuels are readily available is a revelation.

(Often the same fuel is exactly what Royal Dutch Shell & others have in Filling Station Tanks in the UK.)

 

You just never know what you are getting sold other than it does meet the minimum spec unless you check and ask in writing, 

and even then those selling you the fuel might not know.

It could be better than you think.

I'm not arguing about the octane rating or that Momentum99 doesn't give better performance than 95, I'm purely talking about the ethanol content in the fuel and that it can be harmful to your engine in the long term.

 

Its a lot nicer filling up in europe because their pumps (at least in the countries I've been to) show the ethanol content (E5, E10 etc) and you can pick a pump without it. In the UK they don't have to tell you how much they've put in. If you ask them, they won't tell you. either.

 

I'm happy to be shown otherwise.

Well since i have a couple of stripped down Twincharger engines internal corrosion does not seem to be an issue.

As to Ethanol, i would happily run my cars on more ethanol or pure alcohol.

 

Each to their own i suppose.

 

If only one type of fuel or octane was required then thats all there would be, 

and if there was no choice of Retailers then many would be displeased.

 

The last people i trust are Royal Dutch Shell, but then i have been caught out before with their special formulations, 

like many others were back not all that many years ago.

(There recent mis-selling was Green Fuel in the US, which was anything but Green.)

Shell V-Power was 98 ron in the UK and then Nitro+ was launched and is 99 ron in the UK, higher in other countries.

Achieved in just exactly the same way as Momentum 99 is formulated.

Edited 13 January, 201610 yr by GoneOffskiroottoot

Let's not lose sight of the main point here.

We are talking about the 1.2 TSI Rapid (and Spaceback). It is tuned for normal 95RON fuel, does not have built-in auto switching engine maps (my 75 had this, very useful feature) for making use of either fuel when detected, so cannot fully extract the benefits from any higher octane fuel.

Using high-octane fuel occasionally won't kill it (but won't help it either). But long-term use in an engine not designed or tuned for it will ultimately be pointless. Use normal unleaded, save the few quid difference, buy a pie

I think the key point there is that skoda recommend you use 95ron fuel and dont specify it requires anything higher. For me thats good enough.

As long as someone tests them and gives the honest results, 

because as it was with Diesels. VW were forced to admit they cheated.

 

You need to look and see if the higher Octane Super Unleaded reduces emissions like Co2

& if it does, do you care.

FYI I had an Ibiza Bocanegra with the 1.4 twincharger engine.  Always ran it on Tesco 99 or V-Power Nitro.  It used a litre of oil for every one of the 18 months I had it, even after the engine was replaced under warranty at 10k miles because it blew up.  Worst car I've ever owned by far.

?

Did it blow up,

or burn out a valve because they just used a short engine and the old head, or was it a tip come off a spark plug?

 

They were and are terrible, more than 20% of the CAVE engines in the Ibiza, Fabia & Polo (and A1 185ps) 2009-2012 have been replaced and more should have been, 

and then a lesser percentage of the CTHE 2012 to 2014.

 

Poor running and cold starts on 95 Ron even when they are good engines.

But then the Recommended Fuel is Super 98. 

 

(Now they update the Oil Spray Jets and Sofrware on CAVE & CTHE but most are beyond help by the time that is done.

Spark plug tip came off.
