Compared with the cooking sherry available in the former Eastern Bloc countries our 95 Ron is their super.

Didn't realise we were playing chess, but some folk will always buy the cheapest fuel available and education is lost on others (not sure if Corbyn ever went to school, certainly didn't do well at Maths).

False economy in my eyes but it's not my place to say how others should spend the cash.  I didn't spend a tidy sum on a 'performance' orientated car to strangle it.  Speed cameras and those that drive 10-20% below the speed limit do enough of that. 

Since picking up my 2013 Octavia VRS estate 6 months or so ago, I've always used Tesco Momentum in it with the occassional tank of Shell VPower as it's supposed to have superior cleaning agents/additives in it.

 

In my previous car, Mk4 Mondeo Titanium-X Estate 2.5T, I always used Tesco Momentum in that as well. But the odd time it wasn't available and I had to use normal unleaded there was a noticable difference in performance.

I've spoken to one of the developers at REVO and they are adamant that the EA888 engines like the higher octane fuels and they use them exclusively during testing.  RTech tuning also state the high octane petrol has a significant benefit, they actually quote 10-15bhp improvement,  depending on variant/age/condition 

 

 

 

I'm adamant I like sirloin steak and my doctor says eating red meat has benefits and actually quotes a increase in my blood iron (I'm pretty sure that too is depending on age/condition). Whenever I turn on my TV, another doctor tells me eating red meat gives me cancer, the environmentalist tells me cow's farts are depleting the ozone layer. Green peace tell me lentils rather than meat is better for my health.

 

The point is for every specialist saying one thing, there will be another specialist saying something different.  ( just look at the current farce with Corbyn - lip reading specialists arguing whether he said 'woman' or 'people' !) Independent research has consistantly shown there is a difference using higher octane fuels but it is so minute, none of us are able to detect it.

 

There's only one way to prove it (and even that's flawed) - take two brand new cars, fill them exclusively with different Ron fuel - run them identically for several years, then strip the engines down and examine them. And if you were to ask Joe public to drive both cars and say which fuel is which:

 

1: he/she wouldn't be able to tell the difference

2: If they say they could, then if your sample size was large enough, it'd work out approx 50% of folk would guess right. In other words, a pure guess.

 

I've always wondered if those who argue using Shell Super cleans the engine, returns more miles per gallon and increases power,  also use Persil Automatic because it cleans whiter then white and use whiskers because 8 out of 10 cat owners say their cat's prefer it. And when it comes to cars, Audi is better than Skoda because it comes with Vorsprung Durch Technik, ( of which I'm willing to bet 8 out of 10 UK car owners don't know what that means -sounds impressive tho).

 

Several years ago I ran my car for 6 months using Super and 6 months using ordinary fuel. Conclusion at year end? Well apart from my wallet doing less miles to the pound, there wasn't a scrap of difference.  Well actually there was - ordinary unleaded did slightly more mpg but that could easily be explained by car running in more favourable weather conditions.

Most of the USA get 91 octane but they measure it differently to Europe so probably equates to about EU 93 octane.

91 MON (as measured in the US) is equivalent to 99 RON.

RO RON	MON	US: (R+M)/2
90	83	86.5
92	85	88.5
95	87	91
96	88	92
98	90	94
100	91.5	95.75
105	95	100
110	99	104.5

The US use a rating incorporating RON and MON measurements called PON.

That's as clear as mud, seems Americans don't believe in K.I.S.S. unless we are discussing the PRESIDENT.

My S1000XR throws a strop when I've had to put 95 RON in. It really struggles to accelerate and the MPG takes a hit as well.

 

Been forced to use it twice, once on the Isle of Man (thankfully the day I was coming home) and the second time in Belgium.

 

Like I said before, it does depend on your vehicle and what it's designed for.

Buy nice or buy twice... not sure if it's relevant here. But my tuned car 'feels' happier with the better fuel, plus it puts my mind at ease giving it nicer beverages (much like buying Calvados over Sainos brandy [Christmas ref. inserted] )

 

Seems like on stock cars, difference is negligible / unnoticeable. On tuned cars it appears to work better. 

 

At the end of the day, I think it's nice to run what is many people's second highest-value asset on The Good Stuff. Before we all end up in hybrids / electro

Processed food may be cheaper than fresh food but we all know which is better for our bodies LONG TERM. McDonalds can kill you in weeks if you eat it for every meal.

I think the phrase we're all looking for is OM NOM NOM!
