Sonicriot13 0 Posted June 23, 2009 On my way back from the National Day on Saturday I stopped at the nearest services that happened to be Shell. I've never used V-Power before but filled her up and I've found the oil temp is 10 degrees lower now than on the BP 97ron stuff that I normally use. Is this just a coincidence? I haven't touched anything else in the engine. Don't get me wrong I'm not complaining!!!! It's running even better than normal! :D :D :D :D :D Quote Share this post Link to post Share on other sites
Henny 0 Posted June 23, 2009 yup, that's not surprising... the G60 ECU expects higher octane fuel than standard unleaded, so it's always running a little "lean" (for want of a better term!) when running on normal unleaded... Sticking a higher RON fuel in makes the engine pink less meaning the ECU doesn't have to retard the ignition as much, meaning more power and a better, more efficient burn resulting in a cooler running engine... (phew, that sentence was a bit long! :grin: ) I always used to run mine on Optimax (shows how long it is since it ran... :roll: :oops: ) as it wasn't anywhere near as good, or gave anywhere near as many MPG when running on straight unleaded...

timg60 0 Posted June 23, 2009 That will explain the extra 40 or so miles I got from a tank last time i filled her up then :clap: I was always too tight to put the rich stufff in but have been told by many its much better for the g60 engine. Quote Share this post Link to post Share on other sites
blue95 0 Posted June 23, 2009 Try Tescos premium unleaded...99 ron!!!! feckin awsome! Know quite a few peeps on the bmw forum and porsche forum that run it too 8) Quote Share this post Link to post Share on other sites
Sonicriot13 0 Posted June 23, 2009 Sweet. 8) I've never run my current G60 on 95 because I did that with my old one once and it ran like a bag of nails. V-Power and Tesco 99 from now on then. :D Good thing it's just a weekend car!!! :lol: Quote Share this post Link to post Share on other sites

Dont get tesco 99 down ere Quote Share this post Link to post Share on other sites
Jim 2 Posted June 23, 2009 Really impressed with the Tesco 99RON stuff. Put some in my valver the other day and just could not believe the performance improvement and improvement in economy. I had a great drive back from the AGM and was puzzled as to why the car was feeling so lively yet returning such great MPG figures and then I realised I'd only filled up with 99RON earlier that morning (for the first time ever). I think I'm converted to it! Much better than Ultimate and Optimax in my car at least! Quote Share this post Link to post Share on other sites
Sonicriot13 0 Posted June 23, 2009 Just got back from filling up with V-Power again. :cheers: I've always noticed a difference between different fuels but never one so marked as this. It's a beautiful day today and really warm and even in traffic it's running cooler than it did on Ultimate over the winter! Quote Share this post Link to post Share on other sites
The_Dude 0 Posted June 23, 2009 BP Ultimate sucks balls, you might as well fill up with lighter fluid. I've used a few times when I've had no other choice and can't believe how down on power the car felt. Only Optimax or Tesco 99 for me! But then I do kind of need it in my motor! :tongue: Quote Share this post Link to post Share on other sites

My supercharger came free with my car. :grin: You had to fork out on yours. Any car is gonna benefit from higher quality fuel big ben. I recommend V-Power. :D Quote Share this post Link to post Share on other sites
mic_VR 3 Posted June 23, 2009 V-Power and Tesco Premium are both 99RON and the only thing that goes in my car. You definitely shouldn't be putting normal 95RON stuff in it ever as Henny says because it can cause some nasty pinking etc as the ecu is setup to run timing based on the more efficient burn of the quality stuff. Plus VW themselves tell you to put 98RON or above in it themselves, just read the inside of your petrol filler flap.... :wink: Quote Share this post Link to post Share on other sites
big ben 10 Posted June 23, 2009 ah ok, i always thought it was a load of bollocks to be fair, looks like only the best oil and petrol is going in the rado from now on then :salute: Quote Share this post Link to post Share on other sites

dragon green 5 Posted June 23, 2009 when optimax first came out, it was advertised how clean it burned, and showed you the cylinder head after a zillion miles, hardly a carbon deposit in site ! my head gasket blew at 80,000 miles so i gave it the mother of all decokes, had it skimmed,valves reground in, and then back together ! Ran it on nothing, and i mean NOTHING but Optimax at 100,000 miles i was unlucky to have another headgasket blow! Head off, and yes it looked like Mr.Carbon had made it his buisness to coat EVERYTHING !! I wont buy Shell petrol ever again :censored: its been Mr.Sainsburys for me the last 36,000 miles, and no more head gasket failure ! Coincedence ? or conspiracy , anyway i blame the french Quote Share this post Link to post Share on other sites

Slimg60 0 Posted June 23, 2009 when I've run my car on tesco 99 I've always felt it feels worst than regular 95 :shrug: It does feel loads better on other 99ron fuels Quote Share this post Link to post Share on other sites

bananawhip 0 Posted June 23, 2009 Out of curiosity I dropped some of that NOS racing fuel additive in mine for a recent 'Ring trip, upped it too around 104ron! I know it's not set up to run it but the difference was night and day. Awesome economy too, managed to drive from west london to the Nurburgring and put some laps in on one tank of fuel! Expensive at £20 a bottle though Whilst I was out there I noticed the Germans have 'Shell V-Power Racing' too which is 100ron, good old UK getting the bum deal as usual :( Quote Share this post Link to post Share on other sites

I will admit I tend to stay away from supermarket petrol because of the dodgy batches they've had in the past. Whilst I was out there I noticed the Germans have 'Shell V-Power Racing' too which is 100ron, good old UK getting the bum deal as usual :( Could be worse mate. V-Power is 95RON in Ireland... according to wikipedia.... :lol: Quote Share this post Link to post Share on other sites
