BP Ultimate problems

[rsx84]

i went to my machanic the other day as i've been noticing a strong fuel smell from my car, he noticed it as well and before asking me what petrol i use he says you use BP ultimate don't you, he then told me that theres been a few problems with the fuel and the seals on fuel pumps, a few people using the fuel have had this problem and have had to replace fuel pumps but it not being covered by insurance due to "contaminated fuel" just seeing if anyone has heard of this latley??

[rb25]

haven't heard of it before, but i'd be interested to hear any other stories. Could be coincidental.

havent heard of it before,

try to use shell,i use sheel and have no problem abt it,

[LOW25T]

dunno about queensland, but down here shell seems to be pretty crap, put it in last week and car was pinging badly, gone back to bp and she's as good as gold

Been using BP Ultimate for a couple of years now and no problems.

even if the fuel pump seals were gone you still wouldn't get any fuel smell, the pump is sealed in the tank! Look elsewhere for your problem

my mechanic told me bp fuel in adelaide is really crap. Still i use it, only 98 RON here.

[fatz]

stop sniffing it!

Check that the fuel cap is secure, and that there are no leaks near or around. Also jack up the car and check underneath where the tank is for any leaks, could just be a small leak that can easily be plugged up...

you wouldnt want that to catch alight from the exhaust.....big dramas....

Let us know what you find out..

problem was fixed on the spot (loose hose) but it just got me thinking if what he said about the fuel and the problems other people may have had???

Hi guys,

See this thread - it should add to the level of discussion.

Here's the thread:

I work at Bp shepparton here in VIC and our BP ultimate is far better than those that are in the city, the reason you get bad fuel is that if you live in urban areas , the simple answer is more people use fuel and with a 5000 litre fuel tank the last 1000 is basically dregs take my advice fill up in the early hours of the morning when they've just filled the tanks or fill up in stations not used as much, those out of the way bastard truck stops

[MLCrisis]

Patchy, I am sure there is some truth in what you say, but I would be surprised if 20% of a tanks contents could be considered to be "dregs". If station tanks, pumps and filters are properly maintained, this should not be an issue. Clearly it is with some, though.

Cheers.

[Patchy]

it would not be 20% of tanks if you considered that premium, unleaded and diesel all house about 35,000 litres. Bp ultimate is the smallest tank and about those filters i have been working at bp for over 12 months and have never seen any cleaning done to the tanks or the filters so unless there self cleaning... How clean is your petrol?

[lwells]

Patchy: of course the problem if you go for a station that's not used very often is that the fuel (the aromatics, if I understand correctly) start to go "off" and it looses some of its octane levels.

Its my understanding that BP Ultimate is "brewed" to be a 98 RON fuel, while Shells version is lower grade and has aromatics and additives put in to make it "close to 98RON

i have managed a servo, and let me ask you, have you ever seen any big pumping trucks flushing the tanks out to clean them, i have never heard of it being done at quix(mobil) EVER. never personally seen or heard of them being cleaned and at quix as long as the water is below 1000L it is deemed clean, reassuring huh?

no.

from what we were told, all fuel comes from shell, there are 4 pipes coming out of the massive tank, all going to mixing stations, that is where all of the additives go in, apparently they are all the same fuel(s) just different mixtures of different shi*

[MLCrisis]

Hi guys. I have a little knowledge of refineries and the chemistry involved. My understanding is that the BP Ultimate is refined as a 98 octane fuel, which means that the crude cut used as the base fuel is at or near 98 octane. Whereas the Shell Optimax is a base 95 octane fuel (or maybe 96), which then has various additives mixed in to boost the octane level. This way, Shell save on refining costs, but have more additive costs - the refining costs will be the bigger of the two!

Any gasoline fuel, if left for a long period in an atmospheric tank (which all station tanks are), will "weather" - i.e. they will gradually lose the more volatile components (it's all a matter of vapour pressure and the tank "breathing"through the vent). This will generally cause the octane of the weathered fuel to be reduced.

Hope this helps.

Cheers.

Some early R32 and R33 Skylines arn't preimum fuel cars and therefore you shouldn't be using preuim fuel anyway, if your Skyline is after 1995 then they will all be preimum only cars, where as before that it's a mix so you should look up your manual that check that out.

Some unleaded cars will have problems with preimum fuels as they will burn out filters etc quicker than normal.

Also about the fuel:

BP Utimate and mobil Vortex, are 98% ron fuel they don't have any cleaners in them.

Shell optimax is 98% ron fuel but with a cleaner in it, so it will help to clean out your fuel system.

I've run Shell optimax in my own unleaded car it ran much better but Shell state that you shouldn't use premium fuels in unleads more more than once or twice in a month as it can cause problems for the engine.

Also had a WRX and ran all 3 types of fuel through it and the Shell fuel ended being the best out of the three providing much more power and resposne.
