Hi guys just a quick question on my new Skoda Octavia 1.5 which has just done 1000 miles I've got to put fuel in it it in another 80 miles my question is should I now put             shell v Power in the next tank for which will probably be 57 L I think so basically every fourth refill put  v power so it would keep injectors system and fuel system clean I used to use Redex in my old Vauxhall all every 5th tank full but I presume you don't put Redex in a new car for a while or am I wrong please advice thanks a lot guys

Last time I read an owners manual it recommended to not add aftermarket additives to any lubricants or fuel.

 

But it is your car and you can put what you want in it.

Why not just put in Tesco Momentum 99 (99 ron min) every tank, or Sainsbury Super Unleaded (97 ron Min) 

& not waste the extra money on Shell V-Power Nitro +?

 

There is nothing special in the additives / octane booster with the overpriced Royal Dutch Shell Product over the other less expensive Super Unleaded.

The other 2 will be the same or less expensive than Shell 95 ron unleaded Fuel Saver.

Either put in V power / Momentum every tank or don't bother at all.  Many years ago I had a Vec GSI and it had a bit of a dead spot around 3k.  After a few tanks of V power it noticeably improved but as soon as I filled with 95 Ron it came straight back.  It always took 2-3 tanks to disappear.

 

There was rolling road test done on the 'Super unleaded' fuels that you can find on line, from memory V Power won with Momentum 2nd - there wasnt much in it. 

 

A relative put Redex into their Octavia III and got plagued by random O2 sensor problems which went away when they stopped adding the Redex.

In my personal experience over several turbo petrol cars Shell V-Power gave between 7bhp more (VRS245) and 13bhp more (Leon Cupra 1.8T) whereas Tesco Momentum gave 15bhp more (Superb 272) but that was probably due to the bigger IS38 turbo on the Superb compared to the smaller IS20 turbo on the Octavia.

Was that the actual bhp figures you got the cars were on the dyno with the different fuels of 99 ron minimum being used? 

Or a seat of the pants dyno reading?

 

Being winter and now the winter formulation road fuels are in filling stations the minimum octane figures can be exceeded, and the 99 ron can be more like the 100+ ron available across the English Chanel on Continental Europe.

Comparing 177bhp Cupra figure quoted by SEAT using 95 ron and the 190bhp on AmD dyno on 99 ron V-Power. Vrs245 Skoda quoted 242bhp on 95 ron and actual 249bhp on V-Power again. Superb 272 quoted at 268bhp on 95 ron by Skoda and actual 283bhp on 99 ron Tesco Momentum on same dyno.

5th Gear did a test on some of the fuels - screen dump from Youtube.

@ScoutCJB They did do tests , more than once, & when Shell V-Power was 98 ron before it became 99 ron when changed to V-Power Nitro+

Maybe @shyVRS245 had 98 ron min when dynoing the SEAT Cupra.

 

The Manufacturers figures on BHP / PS & Nm torque are a minimum you should get in the UK when never more than 3,000 feet above sea level and in not extreme weather conditions.

I doubt a Dyno in the UK isat more than 2,000 feet above sea level and cold air is blowing at the intercooler.

The Max PS / Nm torque should be better than the figures quoted for the car you bought on 95 ron UK fuel, and more on a higher octane.

 

It is always worth those buying fuels knowing what they are getting when and what formulation.

Royal Dutch Shell have 102 ron V-Power Nitro+ in pumps at filling stations near some Italian Car Manufacturers Factories and test tracks.

Note 2nd Vid.

Esso & BP is 97 ron min & Shell V-Power at that time is 98 min. 

*Tesco Momentum 99 was 99 ron min on sale in the UK at that time.*

Below are the Test Results / Report for Tesco from 2012 on Momentum for fuel economy & emissions.  Comparing their 99 against their 95 and others 95,

also their 99 against a competitors that was 99 ron and had just changed from being 98 ron in the UK.

 

The Tesco Fuels are produced by Greenergy who partnered with Royal Dutch Shell importing base fuels.

Greenergy also produce and deliver road fuels for ESSO and others, independents etc.

I think it's clear that premium fuels are better generally with a higher octane rating and some other additives that help keep things clean/performing.

The variance between them is less than the difference from standard 95 so I say knock yourself out and get whatever premium fuel you have available and that offers what you want.
