New Oil Coming

[Dick W.]

According to Chevron, there will be a couple of new oils coming down the pike in a year or so, one being CK-4 to replace the current CJ-4 oils

During an in-house meeting with CCJ and Overdrive editors in December, James McGeehan, global manager of diesel engine oil technology for Chevron Lubricants said that Product Category 11 (PC-11) will likely present the trucking and construction industries with their first-ever split oil category in order to assure backwards compatibility for pre-2017 diesel engines as well as optimal emissions and fuel economy for 2017 engines. A key factor in this decision are off-highway engine manufacturers such as Deere and Caterpillar, which point out the fuel economy is not a factor in their typical applications and worry that lower-viscosity oils designed to reduce internal friction in an engine and therefore boost fuel economy will not be durable enough in certain harsh working conditions.
As a result, McGeehan said, the first new oil, likely to be designated API CK-4 will be blended to be fully compatible with older oil categories back to CH-4, thereby preserving lubricity performance for older vehicles while providing new protection for new emissions and GHG technologies that will begin appearing on engines as 2017 draws near.

Re: New Oil Coming

January 2016 is three years away, and I doubt if the new standard(s) has been finalized at this point in time. Given that CJ-4 has been around since 2007, it's probably overdue for an update.

Don't go out and buy a lifetime supply of CJ-4. Wait to see what the new standard really changes. My bet is that it will still be okay for vintage engines with sliding surface valve trains, but we'll have to wait until all the technical details are finalized and released.

You noticed the article said the oil would be backwards compatible with CH-4

Re: New Oil Coming

Yeah, but I'm not sure what that really means. I'll wait until I see what the new specs are and the limits on P or other components.

Oil companies and engine manufacturers are busy working together through the auspices of the American Petroleum Institute to define, create and validate the industry’s next-generation diesel motor, which is slated to appear in January, 2016 – one year in advance of federally-mandated Greenhouse Gas emission compliant engines.

A separate oil category, currently being referred to as “API XX,” will be blended specifically for 2017 and later engines with an emphasis on fuel economy and meeting Greenhouse Gas emission standards. It will be up to each engine manufacturer to specify which oil will be spec’d for their engines.
An interesting tangent to all of this oil talk is the glimpse at the likely changes fleets will see as 2017 engine technology takes shape – including several possible pleasant surprises. According to McGeehan, the fuel economy push will allow engine manufacturers to dramatically reduce, or even eliminate, in-cylinder EGR levels. This, combined with the new oils, will minimize soot in the exhaust stream, thereby reducing the load on diesel particulate filters and the number of regenerations required. The upshot is that some 2017 engines could be completely EGR-free with resulting air management enhancements, feature reduced radiator sizes, reduced parasitic power loss and internal friction as well as extended drain intervals while running efficiently at lower RPMs.

There already are new standards for oil, at least for GM vehicles------Dexos 1 for gasoline engines and Dexos 2 for diesels (except Duramax). All or at least most 2013 model year GM vehicles require it. Mainly, the attributes this oil standard provides are most critical for very modern engines with features like cylinder deactivation, direct injection, etc. However, after having done a little research on it, I like it. As soon as my small remaining stock of oil is depleted, I'm going to start using Dexos-compliant oil in all of my cars. There are many brands/formulations which are Dexos-compliant.

Re: New Oil Coming

Remember that modern S-category oils are designed for modern gasoline engines that have "roller everything" valve trains, so they need less antiwear additive.

That's primary reason why CJ-4 is a better choice for vintage engines. It has about the same concentration of anti-wear additive as dual rated oils of the past before any P limitations were adopted, which is about 50 percent more than is allowable in current S-category oils.

All of my engines are roller lifter. One is also roller trunnion rocker.

i have been running mobil 1 in my 1988 silverado since new and it has flat tappet camshaft. this engine is quieter than the engine in my former 08 corvette. the only noise you hear is the squeaking of the fan belt. i think once you run in the valve train on regular oil you can use mobil 1. i ran the original factory fill in the truck till 4000 miles changing the filter at 2000 then i changed to mobil 1 200,000 miles ago. if mobil 1 prevented rust on the body it would go another 200,000

Yup and iffen they had not improved engine sealing, it probably would have prevented a lot of rust. Remember the old adage, "the only Chevrolet engine that does not leak oil is one that has no oil in it".

Hummmmm.... maybe I should not worry about my L71's rear main bearing seal leak after all....

My old Chevys are like my old Harleys...they're not leaking oil, they're just marking their turf.

Re: New Oil Coming

mines leaks but not enough to prevent the body from rusting.

I assume your truck uses a serpentine belt. Clean any of the pullies which show even the slightest sign of rust. Install a Goodyear Gator Back belt. Done.
