Some good reading re: Ford's diesel oils and the low(er) phosphor content on some diesel/gas oils. The ones Ford recommends are not limited to 800ppm phosphorous .

What's wrong with 10w30?  I accidentally picked some up they other day?

Best regards,

Valve tappet follower and cam lobe "slow death in a bottle" ......

Take it back and swap it for the right weight stuff and then bump that with one (1) ounce of Redline ZDDP Booster in each gallon of Rotella 5w40 T-6 full synthetic or Rotella 15w40 T-4 dino oil.    Shake the Redline concentrate very very well before pouring it and shake the treated gallon before pouring from that.

(ZDDP likes to settle out of oil until it heat bonds to all the metal in the engine, it does)

I'd delete it as mis-information at this point .....

Hearing car guys blither on to each other about using Rotella 10w30 dino and Rotella 5w30 synthetic oils in their cars only serves to confuse the heck out of the people here on the Savage site, us Savagers that uses Rotella HDEO 5w40 Full Synthetic T-6 or Rotella HDEO 15w40 dino T-4 in our Savage engines.    

We don't use the lighter weight car stuff, ever.  We use a HDEO diesel type oil that carries multi-engine ratings.    Personally, I wish they had left the Rotella name alone, only applying it to the original class of HDEO oils, as spreading the Rotella brand name out over multiple engine classes and uses including small diesel cars is going to allow casual purchasers shopping at Walmart to damage some of their stuff accidentally, I do believe.

Start out with the right weight oil, as the discussions all vary past that point .... and some of us are old enough to confuse easier than we use to.

               me too to issues both up and down

... and yeah, guys everywhere are getting real frustrated with all this CK secrecy BS, aren't they ??

Both.    Start out by finding the right weight of Rotella then make sure the jug looks like this:

 

or this:





Each has a wrong weight twin out there on the shelf to fool you .... so don't get fooled.    And yes, you should bump both of them lightly according to the bump table in the Tech Section.  

Your Eastwood ZDDP is more concentrated than Redline and it bumps differently (and it is pure hell to get stirred up properly too as it is almost solid ZDDP with just a little carrier oil mixed in)

Hey, toss some 600-800 ZDDP PPM dino 10w30 into a Savage and take it on up to the mountains, let it get toasty hot and see the thinned 10w30 jest fly out the exhaust pipe, right on past those generous piston fitting tolerances.   ticky ticky ticky sez the increasing tappet clearances due to rapid tappet/cam lobe wear

We can try that as an experiment next mountain trip, or mebbe Versy can just share his experiences using thinner/different oils during that one hot summer like when we did the last big oil war.

I think our goal should be to be pointing out the BEST Savage Choices and sticking with it -- otherwise we are just chatting along offering no clear direction to the BEST Choices.


=======================================


With Ford cranking down on the CK rating by refusing it, the flow of  volunteer aftermarket VOA testing will choke down to zero until that controversy gets all settled out.

Or until Shell notices their sales dropping off to those brands who do offer up full VOA data about their new marketing packages.

Dave,

When did American Refining Group in Bradford, PA stop marketing
"Brad Pen" and D-A Lubrication Company of Lebanon, IN take it over?

Thanks for your insight Oldfeller & Dave.  

Best regards,
