harrier1 Posted July 5, 2009 Share Posted July 5, 2009 hey guys just a quick 1 on whats the best fuel for my car? i know the manual says to use the premium stuff at around 98 octane instead of 91 standard. Only thing is iv found the normal stuff from bp is 95 octane and there super unleaded is only 97 does this really make that much differance between the two? not sure what other garages offer at the min but will look into it.

Beavis Posted July 5, 2009 Share Posted July 5, 2009 Shell v-power is best for the zed But the bp stuff at 97 octane is fine. Quote Link to comment Share on other sites More sharing options...

nixy Posted July 5, 2009 Share Posted July 5, 2009 i use tesco 99 but if i was totally sure that boggo would be ok in a JDM i'd use that to save a few pennies at the moment. Quote Link to comment Share on other sites More sharing options...

martinmac Posted July 5, 2009 Share Posted July 5, 2009 Others have generally put it a lot better than me, I just know where things are. The general feeling seems to be that running on the higher octane fuel gives better economy so actually work out cheaper. Quote Link to comment Share on other sites More sharing options...

srobrien Posted July 5, 2009 Share Posted July 5, 2009 shell v-power and tesco99 is the only fuel ever been used in my zed and it will stay like that until I can no longer afford it R Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted July 5, 2009 Share Posted July 5, 2009 lower grade fuels will lose you about 15-20bhp from the engine i use v power, tesco 99 ron and bp ultimate. Quote Link to comment Share on other sites More sharing options...
BulletMagnet Posted July 6, 2009 Share Posted July 6, 2009 Spotted these in the pits at Modified Live @ Brands Hatch. 119 octane!!!!! Quote Link to comment Share on other sites More sharing options...
Chris`I Posted July 6, 2009 Share Posted July 6, 2009 I've always used V-power Cos you're a brand whore Supprised you dont get it imported from Japan Spotted these in the pits at Modified Live @ Brands Hatch.119 octane!!!!! Pretty sure at Bedford you can buy 105RON for track use. Its about 2 quid a litre though Quote Link to comment Share on other sites More sharing options...
harrier1 Posted July 6, 2009 Author Share Posted July 6, 2009 **** that id rather use v power of the tesco stuff and save rest for tyres and/or mods Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted July 6, 2009 Share Posted July 6, 2009 BP do a 105 RON stuff at silverstone for track users. its pointless unless your cars tuned to run on it. Quote Link to comment Share on other sites More sharing options...

shieldsie Posted July 7, 2009 Share Posted July 7, 2009 Used V-power for first 3 years, but having used BP Ultimate no going back. So BP Ultimate for last 2 years in my Zed. Quote Link to comment Share on other sites More sharing options...
Greekman Posted July 7, 2009 Share Posted July 7, 2009 lower grade fuels will lose you about 15-20bhp from the engine Thats a bit too much dude!!! I always use the cheapo stuff unless on a track day and thats only for psychological reasons.... On the motorway there is a bit of a difference on fuel economy and prob works out a tad cheaper but in town i can see no difference at all....then again i drive in my cowboy boots all the time which are about a stone each so it could be just me!!!

Chris`I Posted July 7, 2009 Share Posted July 7, 2009 lower grade fuels will lose you about 15-20bhp from the engine Thats a bit too much dude!!! That fully depends on how well the car can adapt to different octanes. Back in Aug 06, Thorney Motorsport ( http://www.pistonheads.com/gassing/topi ... 7&f=57&h=0 )did a test with a 2003 BMW E46 M3 CSL, and as a control car a standard Toyota MR2. They saw the CSL drop 40BHP by switching from Tesco 99RON to a 95RON. Admittedly the car was mapped for this kind of fuel, but it shows how big the difference can be. Now the Zed is mapped for 98RON, so giving it 95RON over Tesco 99RON, I would hazzard a guess that you could quite easily lose 15BHP. On the fuel consumption side, I have seen many times that 99RON gets me more than enough in higher MPG to cover the extra cost (about 3 quid a fill up) over 95RON. Also, unless you drive around for a good while with 99RON in your tank before using it on track (say drive up there on it), then you probably dont see any benefit of it until the end of the day as it takes a while for the fuel trims to compensate fully for the better octane.
