Oil & Fuel Type of oil to use

[Jerry/MT]

New Holland recommends it's new CJ oil only be used in Tier IV engines.
The cost of many CJ oils make the backwards compatible question moot. I won't be buying any until I have an engine that requires it. And that won't be any time soon.

API Category Status
CJ-4 CurrentIntroduced in 2006. For high-speed, four-stroke engines designed to meet 2007 model year on-highway
exhaust emission standards. CJ-4 oils are compounded for use in all applications with diesel fuels ranging
in sulfur content up to 500 ppm (0.05% by weight). However, use of these oils with greater than 15 ppm
(0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain
interval. CJ-4 oils are effective at sustaining emission control system durability where particulate filters
and other advanced aftertreatment systems are used. Optimum protection is provided for control of catalyst
poisoning, particulate filter blocking, engine wear, piston deposits, low- and high-temperature stability, soot
handling properties, oxidative thickening, foaming, and viscosity loss due to shear. API CJ-4 oils exceed the
performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricateengines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel,
consult the engine manufacturer for service interval.

CI-4 Current

Introduced in 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards
implemented in 2002. CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation
(EGR) is used and are intended for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can
be used in place of CD, CE, CF-4, CG-4, and CH-4 oils. Some CI-4 oils may also qualify for the CI-4 PLUS
designation.

CH-4 Current

Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards.
CH-4 oils are specifically compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight.
Can be used in place of CD, CE, CF-4, and CG-4 oils.

Rick,
I agree with your statement. NH recomends Ambra Super Gold 15W40 oil for my Tier II TD95D (it is a API CH-4 oil meeting NH 330G) BUTthe API statement for CJ-4 oils says they are backward compatible with API CH-4 oils with the restriction that ULSD fuel is used . If high sulphur diesel is used, then the drain entervals might require adjustment. (That's the only fuel availabel for off road use where I live.) So it appears to be an economic issue rather than a technical issue.

I have been using Delo 400 LE which is a CJ-4 Plus rated oil for the last 70 odd hours in our NH and have not priced out a CH-4 rated oil. Delo 400LE is a bit under $3.00 a quart from Costco at present. Do you have any idea of the cost difference between CJ-4 and CH-4 oils? If it's significant then I'll look into finding out where I can get a CH-4 oil.
