Hiall i worked at a uni in the mechanical engineering dep't and there was a guy there testing fuel addetives on a caterpiler eng', not sure size, but it was BIG. Anyway iasked him what the best add' he had tested and he said something with teflon in it. Maybe nulon. Teflons got the lowest co-efficiant of friction, that means it's as slippery as a butchers *****. Is pretty much inert that means it's inactive on seals and the like.$8aus a bottle

 

i dont understand how that would help fuel efficiency at all; i didn't know there was so much drag in the fuel lines... fuel is already an extremely low viscosity liquid with a low flash point, you shouldn't need to lubricate it. You said you work in the mechanical engineering dept., are you an engineer? It certainly doesn't sound like it...

 

So it's a "BIG" Caterpillar engine - Was it a diesel? That makes a huge difference in what sort of additives or techniques are effective.

Fuel injection pumps for those operate at such high pressures, their problems are pretty much unrelated to anything you'll see in a normal S-I engine.

 

The benefits are at every wear point that the oil lubricates.

 

Additives are not recommended in any owners manual that I have examined. If addditives are as slippery as you think would this not cause engine sludge buildup because it will not drain with the oil change??

Just kiddding.

 

Hey finch, sorry about the mix up. The teflon stuff goes in the oil not fuel.

 

Okay. The teflon makes way more sense now. Sorry to flame you.
