allan_thorne Posted April 2, 2005 Posted April 2, 2005 damm, the shell station just off the roundabout @ Perth before you head up the A9 to wards Inverness is closed changing over to BP no more Optimax for me then. the next one is @ Inverness just about got caught short tomight never put ultimate in the scooby yet is it really worse than optimax read a few threads on here that makes me think it is. See the thing is I work for BP and look after the retails site (filling stations) north scotland and the islands and BP claim that their additive is far superior to optimax Mr Graham Simms the head retail man got quite upset with me when I said rubbish optimax is much better thought my P45 was in the post this is a real problem for me as I want to use my company discount with BP but don't want to bugger my car up or loose performance.
wrxmania Posted April 2, 2005 Posted April 2, 2005 That's the difference - BP Ultimate is unleaded with an additive - Shell Optimax is a differently developed fuel. Shell every time I think most users have found, until another proper new fuel is developed to compete. Brian
Gumball Posted April 2, 2005 Posted April 2, 2005 can you use both of them without any real problems? theyr both 97 ronalds!

Brian >> h'mmmmmmmmmmmm well I'm not technical minded me but I work @ the BP Terminal Inverness and BP Shell Esso Tesco Texaco Safeway(morrisons) not for much longer. National All pick up and its all unleaded that they load and for Ultimate and Optimax it is really just what we once new as SUPRE GRENN there is a additive that is added at the gantry so how can shell claim it is refined differently.
the squiggle Posted April 2, 2005 Posted April 2, 2005 Ultimate is 97 RON Optimax is 98.6 RON Buckfast and Cognac would be a good comparison. Does this mean there is no Shell in Perth Grant
scoobymadburd Posted April 2, 2005 Posted April 2, 2005 ohh wee shame no optimax need to go a longer run to get some will you do it Scottie Scoob??
gordon_kerr Posted April 2, 2005 Posted April 2, 2005 << Ultimate is 97 RON Optimax is 98.6 RON Buckfast and Cognac would be a good comparison. Does this mean there is no Shell in Perth Grant >> pmsl Grant
p1ggm Posted April 2, 2005 Posted April 2, 2005 ALL the fuel in scotland comes via grangemouth refinery.....BP its all the same stuff ask any tanker driver
Gumball Posted April 2, 2005 Posted April 2, 2005 Grant......are you saying there nae mare buckfast in glasgow either????????????????????????????? Sorry i see what you mean. use optimax failing that use ultimate if theres none then use buckfast? or was it cognac?
allan_thorne Posted April 2, 2005 Author Posted April 2, 2005 << ALL the fuel in scotland comes via grangemouth refinery.....BP its all the same stuff ask any tanker driver >> most of what you say is spot on but you do have the likes of Mabanaft and Conoco who import fuel and some of the third parties like Tesco etc will pick up product from Leith etc. However how can they state the shell is 98 ron BP 97 ron if the fuel is refined at "Inovenne" Gramgemouth (formerly BP) is'nt it the refining process that dictates the ron is'nt the addivtive just cleaning the valves and all that stuff.
imprezapete Posted April 2, 2005 Posted April 2, 2005 From what I have seen about and hear Optimax is 97 Ron with added chemicals for cleaning. The Ron rating also changes with the time the fuel is in the storage tanks at the garage as well as your car. i'm by no means 100% on the above, but a lot of people have told me the above.
scooby222 Posted April 2, 2005 Posted April 2, 2005 Hi there, no need to panic,you can still get optimax in perth its just not as handy. theres a shell opposite perth prison, next to the mitsubishi garage,but it aint 24 hours. dont know why thevye changed from shell, the prices they charged it should have been a gold mine!
robinh20mrv Posted April 2, 2005 Posted April 2, 2005 well................ i use either optimax or bp ulitimate, and with the gems mapped by stevesimpson it seems to make no diffirence, no flashes on the k/link at all, and yes i have had the k/link checked and its working fine! cheers robin.
Guest Posted April 2, 2005 Posted April 2, 2005 as a few have said ........ it all comes out of the same tanks .... all we see are bp, shell wagons on the road. my dads work used to clean the boilers at grangemouth ..... and he told me this years ago. so unless there are two pipelines, holding tanks, etc ............. its the same stuff ............. different labels ..... same contents ................... just like supermarkets own stuff and kelloggs, etc ......... made in the same place.
dad Posted April 2, 2005 Posted April 2, 2005 dont know about all this fuel stuff but supermarket cornflakes are nothing like the real think! neither are beans ,cola ,tomato sauce................
ANDYJDMSTI Posted April 2, 2005 Posted April 2, 2005 if you are unsure then get some booster in and get on with driving!!!!!!
p3dro Posted April 2, 2005 Posted April 2, 2005 << dont know about all this fuel stuff but supermarket cornflakes are nothing like the real think! neither are beans ,cola ,tomato sauce................ >> LOL keith, very good point I used to work with all the petrol retailers and conversations with them lead me to believe that supermarket fuel is the lowest grade possible with nothing added in but Shell, BP and Esso put additives in hence the reason it is dearer. Dunno if its gospel tho?
the squiggle Posted April 2, 2005 Posted April 2, 2005 << well................ i use either optimax or bp ulitimate, and with the gems mapped by stevesimpson it seems to make no diffirence, no flashes on the k/link at all, and yes i have had the k/link checked and its working fine! cheers robin. >> Robin with you running GEMS, Esp Gems mapped by Steve, then you could run it on cow juice and you wont see Det. As for the rest of use running JDM cars with std ecu's, try filling your tank with Ultimate Esso SUL or Morrisons cr*p and just watch the Knocklink light up for Christmas when you give the car some stick. When i put Ultimate in the my car, for testing purposes, it would not idle smoothly and the det in the 5-6k rpm range was horrendous. So if it is the exact same, due to coming from the same galleries and tankers then my car is Psycho-scematic and should be booked into the nearsest shrink for some councilling. Technical bit on fuel All Petroleum fuel's, Derv, Gasoil, Unleaded. Parafiin, Kerosene, Optimax, Ultimate and Racing fuel, start off as the same thing called Crude Oil. When Crude oil is heated and put under extreme pressure, in a massive tower, the properties of the Crude Oil change to a more refined product. The higher up the tower the processed Crude Oil leaves the tower, the higher the quality of fuel. E.G Gasoil and Diesel are removed at the bottom of the tower and Racing fuel and Aviation Fuel are removed from the top of the tower. This process is called Refractional Distilisation and is used to create all Hydro carbon based fuel. In the section of the tower with gives out Petroleum, the Normal unleaded [95 Ron] will leave the tower at a point just below Super Unleaded [97 Ron], which in turn will leave the tower just below Optimax [98.6 Ron} which in turn will leave the tower just below std Jap fuel [100 Ron], which in turn will leave the tower just below Jap Super Unleaded [102 Ron]......etc. Bottom of the tower would be Heating Oil and it woulfd increase in quality all the way up the tower, improving in quality at each point it leaves the tower until you get to Av-Gas at the very top with a Ron of 118.

Our depots re brand Kero to Jet i.e. they have kero in the storage tank and they put kero into the aviation tank and add dye or vice versa.

Heating oil being produced from Heavy Crude oil and Av-Gas being produced from Light Crude oil. Are Kerosene and Aviation fuel not one and the same. I remember the old piston prop planes used Kerosene. All the above info is based on the Discovery channel and Mrs Graham from 4th year Chemistry ans as i say i am not a petro-chemist Grant

wilky Posted April 3, 2005 Posted April 3, 2005 Piston props use 5 star aviation gas anything from 100- 115 ron, come on a diesel powering a plane, think squirrel meister, think! Suck squeeze bang blow, the basic description of an internal combustion engine. kero and its close cousin desiel need to be under pressure to ignite, hence a diesels lower revs, less power but good torque. Not good for a plane engine which needs high revs and expolosive power. Turbine engines use kero because its under pressure from the turbine effect hence not affecting the engines preformance. Kero is refined slightly finer than desiel hence a slightly better flash point making it better as an AVGAS. You can run a diesel on Kero, ask any gypsy or farmer we ran a Landrover on US AVkero for 6 months in Iraq not advisable we burnt out turbos like it was xmas, but u cannot use deisel on a kero power unit. Here endeth the lesson. Prof. Albert Hoffman, Pertochemical Pioneer and discoverer of synthetic LSD
Gumball Posted April 3, 2005 Posted April 3, 2005 grant I was very impressed with you continual technical ability in such matters! Your talents really are wasted. no joking. Wilky a couple of times now i have heard you mention tabbing and mentions of iraq....................... what were you in?
