dave_morgan Posted March 6, 2006 Share Posted March 6, 2006 I use Dreghorn too, so you could be right Andy. Although I'm fairly sure I also use the one in morningside recently and had the same problems !?! Perhaps the same tanker? Filled up in S Queensferry last night, but haven't had a proper chance to open it up yet to check for sure, but I'm sure I still saw a few unfamiliar lights flickering last night on the way home.

drb5 Posted March 6, 2006 Share Posted March 6, 2006 Once or twice there have been occassions that it wasnt run on booster. twice at most. september-march, 24 weeks, 3 tanks a week=72 tanks 2 of them without booster. Ah ok, Chris. Cheers. 3 tanks a week!!!!!! [] I'm usually on about a tank a week! Link to comment
tino Posted March 6, 2006 Share Posted March 6, 2006 I usually fill up at the Shell station at the Forth Road Bridge, and can't say I've noticed any problems. One thing I was wondering though, is that as most Scottish petrol is supplied from BP at Grangemouth, do they infact supply the octane rating Shell require or do Shell add 'booster' to BP 97. If this is the case, and as the average motorist will use normal unleaded, perhaps the Optimax storage tanks at the forecourt lay longer between refills and are suffering from some kind of evaporation damaging the rating?

imprezapete Posted March 6, 2006 Share Posted March 6, 2006 My current tank was from Shell Musselburgh and Im down about 40 miles to the tank so far and the car feels a bit sluggish. Link to comment
frank c Posted March 6, 2006 Share Posted March 6, 2006 Can;t say i've noticed..but haven't used the car much lately...Usually fill up at Musselburgh.. Should i be fitting a Knocklink......??????? or is there no need to Panic? Frank. Link to comment
ian_finlayson Posted March 6, 2006 Share Posted March 6, 2006 Doesn't optimax degrade over time. Last time I was away at sea the car had a quarter tank of optimax left in it for 10 weeks. When I got back I thought my knocklink had been swapped with a christmas tree light set. It was terrible and car ran like a bag of spanners. I have tried BP ultimate recently with good performance and no lighting. Link to comment
imprezapete Posted March 6, 2006 Share Posted March 6, 2006 I have heard Optimax degrades a far bit if left for long periods of time. Anyone confirm this? Link to comment
Gumball Posted March 7, 2006 Share Posted March 7, 2006 i thought that there was a period of something like 6-8weeks in teh tank before it started baing sh@t Link to comment
dave_morgan Posted March 7, 2006 Share Posted March 7, 2006 I have heard Optimax degrades a far bit if left for long periods of time. Anyone confirm this? That's been my experience certainly. I sometimes go a good few weeks without using the car, and often find it dets more after the break. I rarely completly fill the car up for that reason. Dave Link to comment

Should i be fitting a Knocklink......??????? or is there no need to Panic? Frank. If you can feel a reduction in power, there's likely to be a fair bit of detonation present I'd guess. I wouldn't panic, but a knocklink is a very cheap warning system in my eyes ! Dave Link to comment
bigdavie Posted March 7, 2006 Share Posted March 7, 2006 last night i had to put 95 ron in only put £5 in tho just enough to get me up to the nearest shell garage that i knew had good fuel but anyway my question is this will my car be ok as ive now filled her right up with optimax or should i get some octane booster to be on the safe side ?? Link to comment
dave_morgan Posted March 7, 2006 Share Posted March 7, 2006 Probably less than 10% 95Ron in your tank now, so you should be fine. What car and mods are you running? Link to comment
johnnyr6 Posted March 7, 2006 Share Posted March 7, 2006 Wait a minute, are we supposed to run subarus on optimax?? Is tescos unleaded no good?[] Link to comment
Johnny50 Posted March 7, 2006 Share Posted March 7, 2006 Have always ran mine on Tescos finest...as did the previous owner. Never had one problem at all running it. Also, at Dastek on saturday, after the car had ran, Gerry said it was running spot on, no sign of det anywhere, and it was holdling 14psi (0.9bar) I will move up to Optimax when its getting mapped though.

jimmymc Posted March 7, 2006 Share Posted March 7, 2006 ive recently changed from optimax to bp ultimate as i had a heep of bother in the evo with optimax from morrisons in camelon. just my observation but its night and day now. Link to comment
imprezapete Posted March 8, 2006 Share Posted March 8, 2006 Here Andy maybe we should get Tescos to sell the 99Ron fuel from the Musselburgh Tescos. Imagine all the business you maybe could put their way Maybe they would be interested Link to comment
bigdavie Posted March 8, 2006 Share Posted March 8, 2006 Probably less than 10% 95Ron in your tank now, so you should be fine. What car and mods are you running? its a 99 classic turbo 2000 with a tec 3 remap to 260 bhp thats it afaik !! Link to comment
warby Posted March 8, 2006 Share Posted March 8, 2006 Its not just up there guys, the fuel down here in Cheshire is poo as well. Link to comment
imprezapete Posted March 8, 2006 Share Posted March 8, 2006 New tanker of Optimax in at the shell garage at Musselburgh now. The part clueless attendee said that hes had a few complains about the optimax. Link to comment
frank c Posted March 8, 2006 Share Posted March 8, 2006 Shell garage at Seafield Rd is shut from Monday for 6 weeks ( new tanks) and Musselburgh will be closed after that. Frank. Link to comment
