Thread: Best fuel for Puma 2.2

My bum dyno tells me my puma makes 11.71 jigga-pascalls of awesomeness on the hokey-pokey scale.

See... the 'bum dyno' makes no sense. That's the whole idea. Use a real dyno if you want to quote real figures

Any data you collect (power economy or otherwise) is subject to variance and error. This is made more accurate through having a good sample size. Measure accurately over a large sample size, or else whatever we quote is just rubbish.

Not 10-15 percent though and not in Innisfail mid day and same time of the year.

I was referring to you fuel usage quotes as in the op not your power quotes
Maybe you like bum in mouth not that i ever want to try

I think Toxic avenger sumed it up pretty well, economy will always come down to a whole host of variables. Everybody will be subject to different situations with different circumstances as a result fuel economy will always be relative to ones daily usage. Id say 50% of my kms are done on the motorway hence helping my weekly fuel economy, but in reference to the op's post i think BP is much better than any other diesel out there as they use a better additive/additives in their fuel.

Economy is only one aspect. Driveability, smoothness, more power, are also markedly better with BP IMO. Is that additives or a different grade of fuel? And what are the others doing to the engine? It's like it's always slightly starved of fuel to varying degrees with diesel from all majors other than BP.

We're very careful to use the right oils. Should we be more careful to use the right fuel too?

I have a friend who has been, prior to his retirement, been involved with the fuel industry for his whole life, dealt with oil companies, transported & delivered fuel, operated his own servo etc, and was heavily involved with the 15C Temperature Correction issue.
He told me that there was very little difference in our "base" fuel. He delivered to various sites. He said that there would be minor differences created by additives, but basically, all of the majors were pretty similar.

Yes I've heard the same from a somekne in the know, but I'm not so sure. Can it really just be additives? What about higher octane diesel? Like there are different grades of unleaded. Maybe the BP fuel formula itself is different?

You don't want high octane diesel. Octane rating is about fuel ability to be compressed without detonating. Diesel engines are compression ignition. Lower octane but higher cetane ratings are more relevant. (Cetane rating being being a measure of how little delay there is to burn starting after injection)
