Question DIESEL GRADES

G'day Fellas,

What is the take on these so called "ULTRA GRADE" Diesel fuels as to the "STANDARD GRADE" diesel fuels. (eg: BP Ultima Diesel to name but one).

You hear wild claims of better MPG, cleaner burning, longer life on injectors Blah..blah..blah.

Off course the only obvious downside is the price, but is there any upside at all to these fuels in way of performance and better MPG?

Has anyone done any tests on these diesel fuels on our trucks?
Are they even suited to our 7.3ltr truck diesels or more suited to the higher tech modern diesels??

Cheers,
Reg

We've just got D1 & D2 here, but it doesn't sound like the same thing. Have you looked into the cetane rating of each fuel? Also check for the BTU content per gallon.

Kind of sounds like they just dumped some additive in regular diesel, but I don't know what your regular diesel is like. Have you tried a tank to see if the mileage improved any?
