Guest Bennyboye46 Posted January 13, 2013 Report Share Posted January 13, 2013 Any difference in performance between regular petrol and say BP ultimate? Are you able to mix standard fuel with 'super' fuel? I have a e46 m sport would I notice a difference in acceleration? Thanks Link to comment Share on other sites More sharing options...
harmzsingh Posted January 13, 2013 Report Share Posted January 13, 2013 I've not noticed any real performance differences on my 330i. I'll still use premium fuels (Shell V Power/BP Ultimate) for the added cleaning detergents though Link to comment Share on other sites More sharing options...
iluminusbutterfly Posted January 13, 2013 Report Share Posted January 13, 2013 You won't, you have a knock sensor, any performance increase is either psychological or caused by your wallet being lighter Shabaza 1 Link to comment Share on other sites More sharing options...
rickzsingh Posted January 13, 2013 Report Share Posted January 13, 2013 Didn't find too much of a difference with shell's performance fuel and its normal fuel however it might be better for the engine? I did notice a difference with shell/bp fuel and supermarket fuel.. My car hasn't had supermarket fuel for 6 months now! Link to comment Share on other sites More sharing options...
Guest Bennyboye46 Posted January 13, 2013 Report Share Posted January 13, 2013 Does it do it a lot of good then using ultimate? Is there alot of difference In price (can't say ive ever paid much notice) I've had a cold start knocking for a while that a mechanic said could be fuel pump. When I'm next pretty much out of fuel, worth filling up with ultimate? Cheers for your comments! Link to comment Share on other sites More sharing options...
Rich_D Posted January 13, 2013 Report Share Posted January 13, 2013 Only worth doing on boosted cars or if you have yours mapped to suit the higher octane BP Ultimate isn't great though, Shell V-Power is the best Mengwalton 1 Link to comment Share on other sites More sharing options...
Guest Bennyboye46 Posted January 13, 2013 Report Share Posted January 13, 2013 Does remapping make a big difference? Would you notice a difference on acceleration? Cheers Link to comment Share on other sites More sharing options...
CliffThomson Posted January 13, 2013 Report Share Posted January 13, 2013 I'll add my 2p to this.....Although for diesel. Noticed a BIG difference between standard and BP ulitmate diesel. Funnily enough, Shell V-Power diesel i noticed no difference at all, in economy or driveability. BP Ultimate the difference was almost night and day, the car was much improved. Can't speak for petrol though....The only petrol vehicle i drive is moped class, and i'm hardly gonna tell if there's a difference there! C.

I have a e46 m sport would I notice a difference in acceleration? Thanks :)/> I recently watched a 5th gear where they tested the latest golf gti on all standard and high octane fuel (it was a 230bhp petrol model) Shell V power won the competition by far. BP ultimate didn't make hardly any difference! since then I've been trying to use that. It was only on a couple of months ago so the video will will probably be on YouTube, the test was quite thorough Link to comment Share on other sites More sharing options...
Rich_D Posted January 13, 2013 Report Share Posted January 13, 2013 Does remapping make a big difference? Would you notice a difference on acceleration Not on a normally aspirated engine, especially not a 318, don't waste your money Link to comment Share on other sites More sharing options...
Guest Bennyboye46 Posted January 13, 2013 Report Share Posted January 13, 2013 Ok mate thanks.. What's the best and cheapest way to get a bit more torque? Bit more power on acceleration as I doubt high octane is gonna make a difference right? Link to comment Share on other sites More sharing options...

Interesting I've never tried any 'special' fuel in a diesel, might give it a whirl, I only used to use super unleaded in cars that needed it, 200SX, Impreza, etc and Shell V-Power was the best Link to comment Share on other sites More sharing options...

Guest Bennyboye46 Posted January 13, 2013 Report Share Posted January 13, 2013 Thanks mate what's the best and cheapest way of getting a bit more power on acceleration v power not likely to work is it? Link to comment Share on other sites More sharing options...

You won't see big gains from tuning yours unfortunately, an exhaust, decat & filter to help it breath more easily will help, but it won't make a huge difference Link to comment Share on other sites More sharing options...
Wash Posted January 13, 2013 Report Share Posted January 13, 2013 Thanks mate what's the best and cheapest way of getting a bit more power on acceleration v power not likely to work is it? If you wanted more power from your car then you really shouldn't have bought a 318. There's not much you can do and the easiest thing to do would be to sell it and buy an E46 with a bigger engine.

autosri Posted January 13, 2013 Report Share Posted January 13, 2013 You won't, you have a knock sensor, any performance increase is either psychological or caused by your wallet being lighter That's the point of the knock sensor though it pushes the timing till it senses slight ping then stops so if you put higher octane fuel in you can run more timing which means more performance Webby 1 Link to comment Share on other sites More sharing options...

daz031178 Posted January 13, 2013 Report Share Posted January 13, 2013 (edited) I will put my pennies in. In a car unless it turbo or supercharged to be honest getting power gains is going to be difficult and very expensive. For petrol cars that are normally aspirated the fancy fuels wont do naff all. Now however on a motorbike s**t the bed yes it makes a difference. My R1 is 189kg and as of yesterday on my mates rolling road is now putting out 190.2bhp at the rear wheel (over 1000bhp per tonne) and thats with race filter, exhaust and a reflashed ecu with a full tank of v power set up on the road, before it was running at about 170bhp. But car, sorry mate not really worth it. To be honnest doing it on my bike is pointless as where am I going to use that power? Only did it because it was free ;-) Edited January 13, 2013 by daz031178 Link to comment Share on other sites More sharing options...
Gaz Posted January 13, 2013 Report Share Posted January 13, 2013 I used to use premium in the 330 but purely because it's a slightly cleaner fuel and is meant to be better for the engine in the long run. On the M3 I've used premium everytime but one, and the one time I had to use 95 ron fuel it ran like a dog. Very lumpy and felt lower on power. I'd say performance wise though on a 318, you wont notice much real world difference in the short term. Link to comment Share on other sites More sharing options...

Salim Posted January 14, 2013 Report Share Posted January 14, 2013 On every single BM I have owned since I was 19 I have used nothing other than V-power. There have probably been around 8-10 occasions over the last 6-7 years that I have had to use the normal fuel and I really have felt the difference. I think the extra few pence for the super unleaded is definitely worth it Link to comment Share on other sites More sharing options...
Gaz Posted January 14, 2013 Report Share Posted January 14, 2013 Thought the M3 could only run on SUL, no wonder it ran like crap on 95!!! Well it can run on standard, it just runs s**t. I'd not have used regular had I had the choice but it was either that or get out and push. Link to comment Share on other sites More sharing options...
mit Posted January 14, 2013 Report Share Posted January 14, 2013 Dr T did a comprehensive analysis on this and posted his results. His conclusions were the same as what the marketing says, basically the improvement in fuel economy outweighs the added cost. Dr T 1 Link to comment Share on other sites More sharing options...
