Pixelfill Posted March 12, 2006 Share Posted March 12, 2006 I thought Optimax was supposed to be 98 RON.. Mike Quote Link to comment Share on other sites More sharing options...
RedM Posted March 12, 2006 Share Posted March 12, 2006 There are a fair few threads about this. I think the consensus is that some like it, some don't. Quote Link to comment Share on other sites More sharing options...

super_supra Posted March 14, 2006 Share Posted March 14, 2006 i was running optimax when i got my supra for the first couple of months then the shell garage was sold to BP so now use BP ultimate as the only shell garage are out of my way to get to them and i can not tell any diffrence between the to fuels.

eyefi Posted March 14, 2006 Share Posted March 14, 2006 i've got loads of knock sensor datalogs and from them my reckoning is that occasionally (seemingly random, probably linked to station delivery and age) optimax reduces knock by a small amount. i generally use sainsbury's super. have you noticed that shell don't advertise a ron rating for optimax anymore?

super_supra Posted March 14, 2006 Share Posted March 14, 2006 have you noticed that shell don't advertise a ron rating for optimax anymore? yer i have noticed that its not on any of the pumps Quote Link to comment Share on other sites More sharing options...
tbourner Posted March 14, 2006 Share Posted March 14, 2006 Optimax is the only one with agents in it to clean the valves though isn't it? Which apparently is pretty good and not harmful. I heard that stations can have up to 10% of ANYTHING in the pumps before having to empty them and refill - so if the tanker driver is an idiot and starts putting diesel in the Optimax barrel, it could be a LOT lower RON!!!!

Tourniquet Posted March 14, 2006 Share Posted March 14, 2006 I go to Tesco in Thurock, Lakeside and they have Super something or other at 99ron which I'm led to believe is the highest rating in the UK bar race fuel and/or additives. Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted March 14, 2006 Share Posted March 14, 2006 Unfortunately Ooop North where n00b and myself are, we aren't blessed with Tesco 99 yet so the choices here are Optimax, BP Ultimate or super unleaded. Though I have to say reading the reports on Tesco 99 - I'm not convinced it's any better than the others - the Bio ethanol content is commendable though Mike Quote Link to comment Share on other sites More sharing options...
Scoboblio Posted March 14, 2006 Share Posted March 14, 2006 Yup, the tesco 99ron is popular with quite a few people on here because unlike optimax it clearly states the rating.... but I think that a couple of magazine tests have given it a slating. Personally I stick to optimax or bp ultimate, for some reason the car seems to start cleaner and run slightly smoother on ultimate than it does on optimax Quote Link to comment Share on other sites More sharing options...
jason m Posted March 15, 2006 Share Posted March 15, 2006 I use Ultimate as I have a BP near by and have to say I found it better than the Tesco 99 and as good as optimax - which I used for about a year before moving. The optimax does seem to be less consistant in its quality Quote Link to comment Share on other sites More sharing options...

Blimey! I find that very interesting seeing as you have an uber-single fitted. During the great petrol rip-off of 2005 I used Sainsbury SUL for about three weeks. I found the car slightly smoother sounding with no 'pinking' or owt. I only switched back to Optimax because everyone says to use it.
