Why do people buy high octane petrol?

Speculating I would equip my car with inferior tyres is an insult.

Your education must be lacking severely. How do you come to the conclusion I am a skimp? Because I choose to fill my car with normal Shell fuel, this has nothing to do with the fact I am poor or have a limited budget whatsoever. Another insult.

I choose normal Shell fuel, because I have yet to be proven by facts that the more expensive fuel is going to do what it says on the tin.

IMO these manuals you speak of, given politics etc. I wouldn't put it past the likes of Shell, BP etc. to be paying money to manufacturers to print these things. But hey, this is just a presumption of a fact I am unaware of.

I stand by my opinion that there is no need to fill with high octane fuel over normal fuel on a car with no significant power output, nor is it imported from a country that only sells high octance fuel, and you haven't gone to the expense as to pay for your car to be mapped to a specific fuel like others in this forum.

I am more than valid to have these views, and until you can belittle me with hard evidence, please avoid the insults my "inferior levels of income"

To the Roflcopter, goodbye

Speculating is not insulting.

Saying I lack an education is insulting.

Personal insults are against the rules. You are walking on thin ice.

You may have your opinion however the way you justify and convey your opinion to others is ridiculous.

apologies, I was a little quick off the mark there.

perhaps my post was ill considered.

As you are clearly the 'go to' person when it comes to this kind of subject, could you clear me something up?

This expensive petrol that the OcUK motors snobs are talking about, why do petrol stations sell it?

I am confused, not knowing a whole lot about cars and that, driving a 1.6 megane that I fill with supermarket fuel
I would expect someone with a 2.5l turbo charged fire-breathing monster to have a firm understanding of the scientific facts why cheaper lew RON fuel is ok to use in a high performance vehicle. Could you give me a brief outline, [in layman's terms] of why petrol stations bother stocking this pointless fuel grade if it is not required?
 
And furthermore why car manufacturers recommend this grade of fuel that nobody needs.

Maybe it's a big conspiracy between car manufacturers are fuel suppliers, the extra 4p per litres goes to the car manufacturers! MIND BLOWN.

Showoff, it should run just fine on council estate grade fuel.

I suspect so, but Vpower is not just about high octane is it? :)

I've always believe Vpower has detergents and other cleaning additives in it as well that help to keep injectors and an engine clean. It is for this reason why I use Vpower in all of my cars.

What impressed me quite a bit is when I put Vpower diesel in my 306HDI the engine went from sounding like a loud tractor to just a quiet one, so the diesel Vpower certainly had something in it which helped quieten down the diesel engine.


On the topic of the thread, modern high power cars, particular turbo cars do benefit from high-ron fuel. Infact some manufacturers power figures are based on running 98 Octane or higher fuel, both my Porsche and EVO power figures are based on 98 RON. If you place inferior fuel, say 95 RON then the ECU will adapt for the lower grade, resulting in less horsepower.

On a tuned car mapped for high Octane, well putting in low Octane petrol your asking for trouble, the word detonation springs to mind.

4p per litre, where you getting yours from?

Shell Fuel save round me = 1.29.9
Shell V Power at same station = 1.37.9

8p per litre difference.

V power derv has a lower dagdag rating hence the quieter running...

Yep :) someone ran an Audi V8 on normal fuel and Vpower for a lot of miles 30k plus, they ran one bank on the normal fuel and the other on Vpower, then took the plugs out stuck a borescope down and the difference in deposits was amazing.

Indeed they do, for example my car is mapped to take full advantage of Vpower, run it on lesser fuels and the car really doesn't like it.

This only backs up my reply to you earlier.

Unfortunately I cannot speak slowly on a forum to help you understand.

They put the price higher than their normal fuel

This concludes my economics lesson
