the pennzoil brand no longer makes a diesel oil and has not made one in years, but they do bottle a diesel oil under the pennzoil brand. it is mostly sold down south and up north to canada.

 

Guys knock it off or this one is closed...

 

Pennzoil meets CI-4 which is what the PSD requires!

 

yes i understand that, but you are forgeting what oil is bottled in the yellow bottle. Pennzoil brand no longer has its own diesel oil it shares a formulation with another popular brand. this has been ever since it became part of SOPUS.

 

I use Valvoline True Blue. Seems to work great. Just to add to the thread.

 

In 2003, the manual stated to use CI and if not available to use CH. The the rating system for the industry went to CI4, then to CI4+.

The oil and truck industry moved the rating up to CI4+ in order to meet the needs and demands for a better oil that offered better viscosity protection and soot control... namely for EGR valved motors. Most, if not all oils are CI4 rated now... and I like CI4+ due to the extra "science" that went into them to meet the tighter industry standards.

Go ahead and use your oil and rating of choice. Your right, it is stated in your manual, but things change since the manuals were written. Your not voiding you warrenty and no one has ever "hinted" that one would... I am just a proponent of using the industries latest oil rated oil for MAX PROTECTION (SYNTHETIC OR DINO OIL OF ANY BRAND).

 

Just a bit of info I've seen with my own eyes on this.

(Keep in mind im extremely unbiased on this one, because I could run sandy water in my engine and it really wouldnt make any difference because the bottom end gets wiped out every 20k, so I use whatever oil I can get my hands on)

In the past 6 months or so, I've seen a total of 7 trucks come in, requiring replacement of all 8 injectors simultaneously due to the spool valves sticking. All 7 of these trucks had 15W-40 Rotella NON-SYNTHETIC oil in them, and all were work trucks. I have not seen such an incident with any other oil (or the synthetic Rotella, for that matter), and IMO, 7 trucks is too many to chalk up to coincidence. I used to use non-syn Rotella in my own truck until I experienced this, and have switched to Valvoline Premium Blue 15w-40. I've only lost one injector to date, and while I was using non-syn Rotella at the time, it may or may not have had anything to do with it.

No opinions, no BS. Just 7 trucks, 56 dead injectors, and no explainable reasons or matching circumstances other than oil brand, weight, and type. Thats enough evidence for me not to run it, but lots of others are having fine luck with it, and I myself really didn't have any concrete problems with it when I used it. If there is a real problem with it, I don't have the slightest clue what it might be...but I myself won't be using it in a 6.0 anytime soon.

 

I have just decided to never change my oil...........

 

That should be the end of it, right there.

Use what you want to and be happy. Whether you go off price, performance, or bottle design, to each his own.

 

I read somewhere and makes sense to me that RaCor designed the oil and fuel filtration systems for Navistar and that's why the filters are identical and Ford is more expensive. They have to tack on their cut.

 

OK guys we said play nice or the thread would be locked.

Now it's locked.
