BEST 15W-40 DIESEL OIL Amsoil Synthetic Diesel oil

AMSOIL Synthetic Diesel oil’s API CK-4 5w-30 0w-40 5w-40 15w-40

Amsoil signature series diesel oils have changed in 2017 and AMSOIL synthetic diesel oil’s 5w-30, 0w-40, 5w-40, 15w-40 that exceed API CK-4 and API FA-4 specs have been developed and extensively tested under extreme conditions. With the API introducing two new diesel oil specifications API CK-4 and API FA-4 oil needed to be changed. These 5w-30 0w-40 5w-40 15w-40 CK-4 oil’s will be replacing the CJ-4 specification and this has led to some confusion. In most cases, you will require an oil that meets the new API CK-4 specification. CK-4 is backward compatible with the previous diesel specifications. That means if you are using an oil recommended for API CJ-4, you can simply transition to the corresponding upgraded AMSOIL synthetic diesel oil, which will be available Feb 6 2017.

Here is Information about the two new AMSOIL diesel oil lines CK-4.

We’ve made the transition as simple as possible: New AMSOIL Signature Series Max-Duty Synthetic Diesel

Amsoil CK 4 Diesel oils 5w-30 0w-40 5w-40 15w-40

Oil replaces AMSOIL Premium Synthetic Diesel Oil 5w-40 and 15w-40 [DEO,DME]. And the new AMSOIL Heavy-Duty Synthetic Diesel Oil replaces AMSOIL OE Synthetic Diesel Oil 10w-30 and 15w-40 [OED,OEC] with the addition of a 5w-40 weight.

What benefits do the new formulations provide?

The new diesel oils deliver better wear protection and phenomenal durability compared to industry requirements. Not only are you getting an oil that performs better, pricing remains unchanged.

What should you know about the API FA-4 specification?

API FA-4 was introduced to further improve fuel economy and reduce emissions. As such, oils recommended or the FA-4 specification must meet more strict fuel-economy requirements than oils recommended for CK-4.
There won’t be high demand for FA-4 oils since they’re not backward compatible with API CJ-4 and may only be used in certain 2017 and newer over the- road trucks, when approved by the original equipment manufacturer (OEM).
Initially there will be very few applications in which FA-4 oils may be used. It’s also important to know that using FA-4 oils is optional. Each model-year 2017 and newer application will be different. Some OEMs may require using an oil recommended for either API CK-4 or FA-4 – it is up to the customer to decide which to use. If they desire maximum fuel economy, then they might favor FA-4. But, like I said, demand is expected to be low.

Heavy-Duty Synthetic Diesel Oil API CK-4

Ford* recently announced that it will not recommend API CK-4 or FA-4 oils in its applications, saying it will only recommend diesel oils that meet the Ford WSS-M2C171-F1 specification or oils formulated specifically for the previous API CJ-4 specification. Why?
We’re unsure which CK-4 or FA-4 diesel oils Ford tested, but a company representative said the products led to increased wear in its 6.7L Power Stroke* engine. The new AMSOIL Signature Series Max- Duty Synthetic Diesel Oil and Heavy- Duty Synthetic Diesel Oil formulations contain boosted levels of wear protection beyond Ford’s requirements. With the exception of Signature Series 5W-30, the new diesel oils will carry the Ford WSSM2C171- F1 specification. Signature Series 5W-30 will also be tested and evaluated for the specification once Ford finalizes its 6.7L Power Stroke engine test. We are certain it will pass the test, and the Ford WSS-M2C171-F1 specification will be added to Signature Series 5W-30 in early 2017. You and your customers can be well-assured that all Ford Power Stroke engines, no matter the model year, are well-protected when using AMSOIL synthetic diesel oils.
