I want to know what people are using in their Octavia and what is the best petrol brand.

What benefits has that brand and the quality/mpg/price?

I want to know how to protect my engine, filters and to run smooth.

 

Thanks

I'm using Sainsburys super unleaded (97RON). But mine's a remapped VRS 230 

Tesco or Asda standard unleaded usually as both are close to work and cheap (currently £1.119 p/l). Sampled a few tanks of Momentum 99 but didn't really notice any difference for the additional cost. YMMV.

That 5 pence a litre more for the Tesco 99 ron min over the 95 ron might have been £3.00 extra max to a tank fill and maybe not given any noticeable extra economy but might well pay its way in the long run if your car is a keeper.

Easy enough to actually use the 99 ron and see if you do get even 20 miles more out of a tank when doing your regular routine.

 

The VW recommended fuel is 98 ron when they speak GTI, but Skoda just dont bother making much of that.

Momentum 99

shell v power

Just watched an old 5th Gear testing a variety of petrols from Asda 95 to Tesco 99. 

 

Shell V-Power did best, but the conclusion was "so little difference, not worth the extra cash...."

 

There was less than 5bhp between the best & worst petrols. 

 

Of course, they didn't discuss engine longevity. 

Have they done a newer one than these with Tesco Momentum 99 or Shell V-Power Nitro+ 99?

Cant find it.

Any testing comparing economy with a more efficient engine because it is running a higher octane on a car with a MAP that 

adapts would be good.

Tesco have the testing they had carried out available to download.

Momentum is produced by Greenergy that also produces for ESSO and others and imports the base fuel with their partner in facilities 

Royal Dutch Shell.

The cheapest, usually Sainsbury's standard unleaded.

Sure it's easy enough, but there are so many other factors that could influence the slight increase in miles per tank. Even a regular routine isn't completely repeatable. I managed 44mpg (indicated) this morning for my commute to work, which is pretty much my best ever in the morning. This beats the best figure I obtained whilst running 99 RON over a few tanks, which was about 42mpg.

 

The biggest influences on fuel economy are external factors such as traffic conditions, getting lucky with traffic lights, wind speed/direction, temperature etc. This makes it very difficult even over a 5 day period of commuting the exact same journeys at the exact same times to and from work.

 

The point on 99 being better long term for the engine may be true, but again difficult to quantify in any real, measurable terms.

So many factors indeed.

But then when you drive the same car maybe 365 days a year or over a year you either know the difference or not, 

you only go 400 miles or so between buying fuel as it is.

 

If you are aware of no difference then maybe then there is no difference, if you use fuelly or monitor fuel use then you might know.

Those running cars for 3 years (Leased) might well be business users and will or should know the fuel usage very well over the seasons and their working week.

 

Brands & Supermarkets and 95, 97 or 99 available is good and people have choices where or what they buy, 

but sometimes some do not have a clue what is what who supplies it, and is it just octane that is different or is it detergents and do you want detergents.

 

100-102 ron in Continental Europe is lovely stuff and shows if your car benefits from it what crap can be sold in the UK.

 

PS

Dunc69 said he watch Fifth Gear testing Asda 95 to Tesco 99 but i can not find where that happened.

Maybe my bad or his if somewhere they did do tests with 99 octane.

@Awayoffski it was a repeat on Sky. They were testing the new Toyota GT86  and Tiff was racing a Lamborghini Gallardo in the same episode if that helps?

Same here, my 230 loves Sainsburys Super Unleaded, if she's been really good she gets V Power from shell

Shell V Power Diesel for me

V Power has been Scientifically proven to make a driver look far more sophisticated and sexy whilst standing at the pump.

It certainly does, I get loads of cougars looking at me

 

 

Tesco Momentum 99 mostly. If I can eat their food, then my car can drink their petrol.

I want to decide which one is better as a quality wise.

I presume the Asda`s has more dirt in it than the ESSO, shell or BP. My point is to find out which brand is cleaner and protect my engine.

Edited 19 May, 20179 yr by decebal

There are only a handful of major refineries within the UK. Most garage brands source fuel from "local" refineries and mix a tiny proportion of additives to differentiate their products. Dirtiness/cleanliness more likely depends upon how frequently each individual garage cleans its underground tanks & pumps than where they source refined fuel from, as it mostly comes from the same depots. Many people swear by particular brands but I think that itis mostly placebo. Higher RON fuel will perform better within tuned engines, but for most verhicles and owners the difference is negligible. All UK fuel meets strict quality standards. The best way to protect an engine is service it regularly with good quality oil and to avoid thrashing it regualary or from cold.

There is a thread on here about it, 99 Ron petrol at Costco.

Another for tesco momentum. Used this in the previous Fabia vrs's (message in the fuel flap) and stuck with it ever since ! 

any old sh!te

 

it's an oil burner after all

decebal, why would Asda Filling stations get refined fuel with dirt in it, the tankers are not dirty, and ESSO fuel comes from the same locations as many other filling stations including Tesco, delivered by the Tankers Greenergy use.

ESSO fuel even supplied by Greenergy as is Costco's.

http://greenergy.com/uk/independent 

The most used filling stations are likely safer for less H20 in them than small rural station not getting deliveries very often, 

but then thoswe type of filling stations are much rarer and are likely to have newer tanks these days.

Your petrol engine car has a Inline Fuel Filter, possibly a 'For Life' Filter which some now change at 40,000 miles.

I tend to use supermarket fuel and then add Millers Petrol additive to it.

I started using the diesel version on my previous VRS and when I changed to petrol thought I would carry on, whether it does any good or not.
