Best Diesel: Shell? Caltex? BP? Mobil?

[gavs]

The best diesel I ever used, which resulted in a 40km gain out of the tank of fuel, was from a BP servo which sold the proper BP Ultimate diesel.

The original BP Ultimate diesel was actually a blend, although I could never find out the exact ratios, or the exact ingredients. What I was able to find out though is that it was a blend of regular refinery grade diesel, animal fat-derived bio-diesel and a new thing called GTL diesel. It produced less smoke, better fuel economy and more power, unfortunately it was only on a trial basis here in Australia as we dodn't have the sheer volumes of diesel vehicles to justify the price of the GTL diesel.

GTL is short for Gas To Liquid technology. It is done in few places around the world, generally in the horribly poorer nations in Africa due to the expense involved in it. To put it in laymans terms, it means turning LNG, or Liquid Natural Gas into a very, very pure form of diesel, much better than that which is derived from crude oil. It has a higher cetane rating and combusts much cleaner without all the other nasties generally associated with crude derived diesel.

Unfortunately there are 3 limiting factors to it's introduction:
1) It doesn't have high lubricity properties
2) The plants to manufactue it are VERY expensive to set up
3) The only cost effective places to set up the operations, are generally in poor, civil-war ravaged countries with access to natural gas reserves.

To give you all an idea, Shell ran it in it's Le Mans racing program in the R10 TDi as a blend, i think at 20% ratio.

This stuff can also be produced from Bio-Gas, so diesels really are the most environmentally friendly ignition engines

Just put the SpeedTec Diesel from LiquiMoly in my tank. Should improve acceleration and visible smoke. I can see less smoke in the mirror, will comment on acceleration and fuel economy in 1 week time.

hi I just bought a new golf 6 tdi and wanted to know about this BP Ultimate diesel. Is it a higher price than normal diesel and is it worth getting it if I see it around ?

I think I will use BP for all my diesel since it seems to be the most popular one here. I see diesel is a good price at the moment hope it stays low...

Interesting info....

one thing that is particularly interesting - the fact that the GTL diesel is made from LNG, but is expensive in capital costs and manufacture - here's a solution - run you're diesel engine on LNG - can and IS done, and produces very good results. you can run a diesel engine on up to 90% LNG, and get good improvements in power and longevity.

(plase everyone note that we are talking about LNG, liquefied natural gas, and NOT LPG - liquefied petroleum gas)

Yes, we don't want people trying to fill their tanks with bbq gas

This is the specs on the BP Ultimate diesel
BP Ultimate Diesel is a refined premium diesel fuel with higher cetane and lower sulphur than specified in the Australian Standard. It is formulated to burn better than ordinary diesel fuel and remove deposits from vital engine components such as injectors, enabling engines to run more smoothly and efficiently. BP Ultimate Diesel is formulated to help protect the engine against the harmful effects of corrosion and wear. BP Ultimate Diesel’s foaming characteristics have been modified to reduce the likelihood of spills and splash back. Compared with ordinary diesel, using BP Ultimate Diesel will provide;
• • •
Protection against rust and wear Reduced foaming, leading to quicker, cleaner and safer refuelling Minimal rough idiling
BP Ultimate Diesel is designed for use in normally aspirated and turbocharged high speed diesel engines.
PROPERTIES
BP Ultimate Diesel exceeds the requirements of AS 3570, the Australian Standard for Automotive Diesel Fuel, and the requirements of the National Fuel Quality Standards 2000 diesel determination of 2001. BP Ultimate Diesel is comparable to EURO 5 diesel fuel.

Cetane rating 50 min typically 55 to 60
Sulphur 10 mg/kg max

Release date: 02 December 2009

BP Australia advised its customers today that ongoing issues at its supply terminals have delayed the company’s ability to restock a number of its service stations in the Perth, Adelaide and Brisbane areas with BP Ultimate diesel.

Supplies of regular diesel are not affected.

BP is putting a number of measures in place to ease the supply situation. One immediate action is to replace BP Ultimate diesel with regular diesel at all affected sites.

Accompanying this change will be point of sale information to ensure customers are made aware that only regular diesel is being supplied.

BP regrets any inconvenience caused and will update customers as and when BP Ultimate diesel sales recommence.

Doesn't affect Sydney - only because it's not available here

Perhaps this might have something to do with it - BP Says Australian Oil Refinery Unaffected as Workers Strike

For the last 10,000kms I've been using BP in every tank usually from the Albion Park BP.

I did find though that the car ran a bit better when I filled up at Picton BP of all places. Didn't froth as much and didn't smell as much either. I've never put a tank of Premium Diesel in, wouldn't hesitate if it was available close by though.
