is there any difference between different brands of petrol? Also. does petrol go 'out of date'?

Answer 1

Yes there are differences depending on what hydrocarbons there are in the petrol. I dont think petrol goes out of date - considering it came from oil which is the remains of dead animals that have been buried under ground for millions of years I don't think it would have a sell by date. Don't know for sure though...

Answer 2

There are differences - my car never gets as good fuel consumption from supermarket diesel as it does on the big-brand fuels. The base fuel is the same, but the additives differ.
My Metro years ago seemed to go further on Texaco petrol than anything else. The Rover diesel I had after that seemed happy with Texaco, Esso or BP, but didn't like Tesco, Sainsbury or Shell.
I now have a Renault diesel and it seems to like Total and Texaco best.

Petrol can "go off" unless sealed away. The more volatile hydrocarbons evaporate out into the atmosphere, leaving only the less volatile (harder to ignite) compounds behind. As most car tanks and carry-tanks have breathers to prevent pressure build-up, this can happen if they are left for a few months.
Petrol that has been "breathing" for a year will make an engine difficult to start.

Answer 3

There are transformations - my motor automobile through no skill receives almost as good gas intake from nutrition marketplace diesel because it does on the large-style fuels. the bottom gas is the similar, even with the indisputable fact that the elements type. My Metro years in the previous acknowledged to flow extra on Texaco petrol than some thing. The Rover diesel I had after that acknowledged pleased with Texaco, Esso or BP, yet did now no longer like Tesco, Sainsbury or Shell. I now have a Renault diesel and it style of feels to love complete and Texaco impressive. Petrol can "bypass off" till finally sealed away. the added risky hydrocarbons evaporate out into the ambience, leaving in reality the less risky (tougher to ignite) compounds on the again of. As optimal motor automobile tanks and carry-tanks have breathers to stay faraway from pressure construct-up, this may ensue in the journey that they are left for some months. Petrol that has been "respiration" for a twelve months will make an engine complicated to commence.

Answer 4

Petrol does go out of date.

The fuel companies develop different petrol throughout the year - ie. summer petrol and winter petrol. Petrol vapourises more quickly in the summer when the air is warm so in summer the petrol is less volatile than in winter. Therefore you may have problems if you store it too long.

Answer 5

yes and yes but all gas is the same the only difference is what additives the company adds to it OK, like tecron chevron Mobil has these and arco has theirs, OK just use whats printed in the vehicles hand book, and printed inside where you put the gas ok, and all fuel must comply to rules and regulation of the DOT Laws (Department of Transportation) so don't worry to much just use the cheapest stuff, p/s all gas comes from the same place, it comes from oil, crud oil and heated in large vats and the first thing off the top is gasoline OK, all the same at the start, and yes it goes bad in about 6 to 8 mounts it will smell like turpentine and the car will maybe run if does it will buck shack back fire and you will smell it will has a very distinctive smell if the vehicle is going to be parked and length of time use Stay Bil additive will keep the fuel from going sour as they say, when it goes bad the octane leaves so you just have whats left over from the refinery proses

Answer 6

Petrol doesn't nessecarily go out of date, but old gas will make your motor run crappy. That's why they make Stabil. It keeps the fuel good for stored gasoline. I bought a car that had sat for a few years and When I finally got it running(new battery, spark plugs, wires, distributor cap and rotor, oil change, etc...) it ran like crap. It was just the old gasoline in it though. I drained the tank and filled it with fresh petrol and it ran fine. Thats why when I store my dirt bike for the harsh winter I always add stabil to it, or else I just run it out of gas. Any fuel I have that is a fuel/oil mixture I add stabil to it to because I can't run it in my car. Well good luck I hope this helps

Answer 7

Yes, a big difference. Petrol doesn't go out of date as long as it is not in direct sunlight

Answer 8

More to the point, is, what we call petrol, actually petrol, it does`nt smell like it any more. I wonder...............


Apparently, it is said it does go off.

Answer 9

it dnt go off as long as its in a sealed container it can evaporate. some use more aditives than others shell optimax gets higher octane from something they do to da fuel where as tesco uses adittives

Answer 10

I dunno about it going out of date...but my other half will only use Asda petrol in his car. He reckons it lasts longer no matter what the mileage - he can't do as much with other brands.
