Rotella T6 Synthetic CK-4 Rating
Posted by: Ratt643 ()

I did a search and didnt find anything but this may have already been covered. I havebeen running Rogal Purple HPS 10W30 since mybengine was rebuilt. Its getting harder to get the Rogal Purple. I looked at the Shell Rotella T6 Synthetic. It has a CK-4 rating, not tbe CI or CJ-4 thats recommended for ojt engines. Im wondering if it has enough zinc for out cam and lifters to survive?

Why not become an Amsoil dealer and you can have all the good oil right at your shop when you want it? They have the Z-Rod oil made just for the older cars and then there is also a 10W-40 diesel oil that I use in the race car. They also have the GL-4 transmission fluid.

If interested contact me.

The Tractor Supply diesel oil is also a great option for our Corvair engines with flat tappet cam and lifters.
At a more reasonable cost than the name brands like Rotella or Amsoil.
Walmart also has a store brand Diesel engine oil that i have used with good success in street Corvair engines.
Your experience may vary , of course.

If this is about the oil spec / rating it includes CJ-4

Yes, and it comes in bigger containers, such as 2 1/2 and 5 gallon ones
I use it my 2005 Dodge SLT 4 door with 5.9 Cummins Diesel that I tow with and change it every 5000 miles of less.
Or late Spring and late Fall, since the truck does little duty over the Winter.

I do know that Ford kicked a few of the new "CK" oils off their list of approved oils for Ford Diesel engine trucks.

Richard commented about the new CK oils and you can search for it. I recall he recommended not using the newer CK oils until a few "concerns" are addressed.

Ever since Shell oil technology group answered my question about the new T4 having over 1000PPM zinc with other advanced anti-wear additives and cost me a complete engine rebuild. I wouldn't touch any of the Shell products out of principal only. They may have some good oil but I'm not going to test their oils for them.

I've still been using T4 Rotella CK-4 10/30 and would like to hear if the CK is still good for our purposes. My main objective is something easy to find when folks are adding oil or changing it themselves later. I usually buy a few when on sale at O'Reillys or NAPA. Harder to find than 15/40.

Jim, think of the 15-40 type as having a constant viscosity over a certain temperature range. The 40 just maans it will have more viscosity to a higher temperature range/ limit.
Than a 30 would.
I would not use a CK rated oil in any of my engines, with the exception of the wife's 2016 Subaru Forester.
Which happens to take a 0W30 or 5W30 oil
For that I use Mobil 1

Driving less than 5,000 miles a year, the longer oil change intervals of synthetic oils are of less value to me, IMO, as I still use non-syn oil in a CI or CJ and "approved by richard1. I change my oil once each year just before storing for winter.

If your having trouble acquiring Royal Purple, try Autozone as they were still selling Rotella T4, non synthetic, in 10/30 CI/CJ and also carrying Motorcraft Diesel, 10/30 in CJ. These were still on richard's OK list, though some of the diesel oils have less zinc levels than in past.

I might consider a heavier oil except for our wide range of temps in Missouri.

As always I will be interested in richard1's updates.
