Found someone that is making an API registered CJ4 spec'd oil in the 5W-40 synthetic weight that some of us have been looking for. As of today, CJ4 spec'd oil is only available in 15W-40 weight!!

Citgo makes an oil called Citgo - Citgaurd "syndurance" Synthetic 5W-40. Be careful becuase there is a synthetic blend 5W-40 available too... so make sure you get the 100% synthetic version!!!

The PDF file/link below has the info about the oil and there is a toll-free number to call to find dealers in your area. I was given two names and only one can order it for me in gallon jugs.

The price I was quoted was $21.00/gallon and they have to get back to me on Monday about ordering it. This formulation is a PAO "true synthetic" like Mobil 1 oils are... which is slightly different than the Group III synthetics that Rotella markets. Both meet API certifications for CJ4... but this is the first oil I have seen in synthetic 5W-40 weight that is also CJ4 spec'd!!!!! I already use Rotella-Syn and buy it at Walmart for roughly $18.00/gallon.. the the few extra dollars is no big deal to me and I get CJ4 spec'd oil!!!

Before anyone adds tho this thread about Chavez and his comments at the UN about President Bush (which I find horrible)... I have no problem buying the weight and type of oil from Citgo since I have no other choice at this time... if Mobil, Chevron or Rotella would launch their synthetic version of CJ4 oil.... then I would buy it first... but until then... I will place my order for 5 gallons next week

 

Beachbumcook, I'm glad you found your synthetic CJ4 oil. But you're incorrect with the 15W-40 being the only oil currently available. I just put Rotella 10w-30 CJ4 rated in mine about an hour ago.

 

Oops... you are correct.

I forgot about the 10W-30 oil.

Have not seen any out at retail yet... therefore it slipped my mind.

However... are you going to run it year-round... or just for the winter. I will not personally use 10W-30 due to the shearing effects that the 6.0L does to oil and Ford does not want people to use 10W-30 when towing... this is why I have sort of mentally passed over it... but you are 100% right that it is CJ4 spec'd.

I stand corrected.

 

I am only going to run the 10w-30 until the next oil change, which should get me through the winter. I won't be towing very much over the next two or three months. Even when I do tow, the temperature should be well below 50*. According to my PSD supplement, 15w-40 must be used if doing heavy trailer towing with temperatures above 50*. I'll be using either Delo or Rotella 15w-40 at the next oil change. If Delo isn't CJ4 by then, I guess it'll be Rotella.

 

Your plan and understanding is 100% right on....

 

Amsoil makes a CJ4 5W40

http://www.amsoil.com/StoreFront/deo.aspx

 

It is not registered with API, nor does it carry the API starburst mark for being API registered. They say it meets the CJ4 spec... but who knows???

All I know, and many others, is that if I ever have a problem and Ford thinks it is oil related... I have no proof that I used an approved API spec'd oil... only Amsoil'd word... and for me, that is not good enough!!! On the same note to make my point... NAPA/WIX states that the filter they sell for the 6.0L motor is OEM spec'd, but it has been pretty well documented that they are not in other threads... there again... just because someone states that it is OEM spec'd or meets a certain specification is not good enough for me... I want to see the industry approved/accepted API service mark stating CJ4.

 

I can't find where Citgo's 5w40 is registered either. It is not listed on the API webiste as CJ4 registered. I have not persoannly seen a bottle of this stuff but no where in the two documents you provided does it say it is API registred...only that it meets or exceeds API CJ4 standards.

 

Fair enough... and when my local distributor calls back... I will double check to make sure it has the API service mark on the jugs. Quite possible that the newer CJ4 oils from many oil companies may not have been updated on the API website (just a hunch... no proof)?
