Where's the boneheads that say don't run fuel adds? Shouldn't they be posting away their ignorant rants in here by now? Oh, nevermind. They are probably busy re-installing or running injection pumps and injectors back and forth from where-ever, or arguing with their dealers about warranty issues for hoofed injectors and pumps.

 

I dont run any fuel additive

 

The spool valves that stick... those are on the oil side of the injector, not the fuel side.

 

lets just say diesel fuel sucks now with very little lubercation in it now no lube on injectors is just going to give you problems in the future. ultra low sulfer = ultra low lube only way to get it back is a good additive.

 

That is true, for our older trucks. DPF trucks that's not so true, you will have more problems running a higher sulfur content, since the sulfur increases emissions and will plug the DPF faster.

 

Not if it's missing

 

Yup!

 

i also use the Ford fuel additive
