At my local petrol station they sell super unleaded. My question is it worth paying the extra 3pence per litre

Question

This does not sound much, But works out at an extra £1.50 per tank of petrol.

Answer 1

I love my Car! So yes.

Answer 2

The fact that we are living and breathing and able to do all these things. The fact that we are not rocks and some divine coincidence made use who we are instead of some inorganic atom. The fact we can give things worth. We can categorise. Its all beautiful, the sight, the sound, the feel, the emotion, the taste. Even pain. We can feel that not many other things can. Pain may be painful, but we can feel it just as we can feel happy. Its amazing really that out of all of this we can do these things. Although it seems to suck sometimes its still wonderful. random fact: if you shoot a rabbit, it doesnt know why it feels pain, it doesn't register that there is an explanation, it just knows it feels pain and as a reaction will run away, even if its dying. Shoot a human (even if they did not know what a gun was) it would realise its something launched, have some sort or knowledge of what to do and so on. I dont think this was relevant but its written now... But if youre looking for one reason it would definitely be pie.

Hi

I used to have a 2.3 litre normally aspirated (ie non-turbo) Saab 9-3 and I noticed a 10% increase in miles-per-gallon (reading from the car's own trip computer) when using super-unleaded from Shell or BP.

How big is your engine?

Answer 4

Does it have a higher octane number i.e. normal is 93 and super is 95? If super is higher, It should give your car an extra kick. It wont increase milage though, because your car uses petrol at a given rate depending on how many rpm you are driving at, or a certain amount per rev.

Answer 5

Older cars were designed to run on leaded petrol. When the pumps changed to unleaded we had to buy a 'lead supplement' to add to the unleaded petrol. This supplement was later added to the fuel and called 'Super Unleaded'. So the answer is if your car is designed to run on unleaded petrol use the standard (cheaper) grade.

Answer 6

Look at it like this; if you buy ordinary unleaded its rather like buying gin at 35 of alc. If you buy super unleaded its like buying gin at 50 of alc. Its all to do with the octane level in the fuel, the higher the octane the more efficiently it burns and thus makes your car go just that bit faster. Higher octane fuels tend to be less dirty and keep your engine a bit cleaner.

Answer 7

I tried super unleaded for a week keeping a record of milage done then did the same on normal unleaded found no noticable difference. covered a 1,000 miles each time

Answer 8

If you have a Subaru Impreza WRX etc or a Super Car you will notice a difference (only slightly - a few HP) but if you have a 'normal' engine (non-high performance) you'll hardly notice any change in fuel use or performance.

Answer 9

It all depends on your engine size. Anything less than a 1500 will not run economically on Super-unleaded.

Answer 10

My g/f is convinced she gets more miles out of superunleaded... but i'm not sure if thats just her imagination on the fact it costs more and has the word "super" in it.

Maybe superunleaded is better to keep car running well... ?

Technically I don't know the answer to your question but good luck in getting a qualified reply from someone who knows more.

Answer 11

Not unless your high performance vehicle needs it. Most vehicles do not and may run hotter with the higher octane.

If you have a knock, then use high octane, else use lowest possible.
