All too often there are guys running 50/50 WMO and diesel. How thick is that? As for generations of trucks, if I had a stroker, you couldn't pay me to do this. One quart of ATF in 18 gallons of diesel won't change anything as far as thickness though, maybe half a percent but ATF is thin overall.

 

What does thickness of the fuel have to do with the conversation? Today's ATF has additive packages which do no burn cleanly Therefore, they leave an unburned residue which the close tolerances of today's pumps do not tolerate very well. Again, thickness of the fuel has nothing to do with the problem.

 

honestly that reply made no friggin sense. ash and smoke and everything else you said does not happen inside the "tight tolerances" of the new pumps of today. unburned fuel residue would be inside the combustion chamber right? again it would have nothing to do with these tight tolerances. if you pump water through a pump like i have, it will do it easily. Thin diesel works well too. If you thicken the fuel with something like wmo it will thicken the fuels mix and potentially have problems but these would be more seen in the fuel pumps rather than the injection pump. In my siggy you can see the truck i refer to and its fuel system is nothing modern......and i mean nothing. It has a remanufactured pump that is the same as it was 20+ years ago. like i said earlier, new trucks yeah i wouldnt do it but mine can burn anything and some ash from atf or the two stroke oil i use doesnt scare me as it burns in the combustion chamber and leaves those nasty residues there, not in the fuel system but hey i could be wrong.

 

I run gas in my trucks...

 

good on you bro!! haha

 

The burning example is just to show that modern ATF has additive packages that contain particulates which are larger than the Cp3 tolerances is designed to handle.......the burning of the ATF just will show you what is contained in the ATF.

 

What ATF are you referring to? There is a specific type to use, not modern ATF like the type IV or newer. The merc 3 is the stuff everyone uses. I used to hate on it but not any more.

 

Thats correct - the additives and friction modifiers in modern ATF are abrasive and thats what wears the pump. It will also leave deposits in the combustion chambers.

 

Thank you!

Thats right, ATF has the abrasives in it to help the clutch packs with grip.

And as they said, it's not ashless because it wasn't intended to be burned in an engine.

 

No offense to the initial thread starter. But this thread and any similar ones are stupid and worthless. People can tell stories an argue on this topic for hours. And no progress with ever be made. People believe what they want to believe. In the end they are going to do what they want. Reguardless of what anybody says. Its your truck do as you wish
