Why do so many Americans hate European trucks?

Do some more digging @Caesar and see what Volvo/Mack recommendation on FA-4 is. Also, what special spec does Paccar have?

 

Exactly, for some reason the MX engineers designed their engines in such a way, that they use little bit of oil. No problem what so ever.

 

LOL, you thinking a bullet point @ engineer design meeting was this engine must consume noticeable oil for the customer/reputation on the line!

 

The API released two new oil standards at almost the same time, the FA-4 and the CK-4 standard. The CK-4 standard is suppose to be the replacement for the CJ-4 standard, in such a way that any existing engine that uses CJ-4 oil should be able to use CK-4 oil. That at least is the idea.

FA-4 oil is for newly designed engines, not for (most) existing engines.

It's just like with the VAG oil specifications I mentioned. Almost, all VAG engines can use 504.00/507.00 oil, but that doesn't mean oils confirming to that standard don't change/improve over time. Originally these were 5W-30 oils, but the latest are 0W-30 oils.

In contrast, the new 508.00 oil standard is for 0W-20 oils that can only be used in the newest VAG engines.

 

Thanks for not answering question as usual.

 

I'm sure that during the development of the MX engines it was noticed that the engines use a bit of oil. I'm also sure the developers could have made them not to use that little bit of oil. For some reason they choose to let the engines not to do that.

 

You mean this:

Volvo - APPROVED
API CK-4: Volvo VDS 4.5

API CK-4: Mack EOS 4.5

API CK-4: Renault VI RLD 4

API FA-4: No specification and not allowed for use in EITHER new or older Volvo or Mack diesel engines

• Volvo & Mack (Volvo owned) have new specifications for API CK-4, but do not allow use of API FA-4 oils in their engines
• Volvo & Mack specifications are built around tighter requirements for improved oil oxidation performance as measured by the new Volvo T13 engine test versus the typical API CK-4 or API FA-4 Volvo T13 requirements
• Volvo announcing a 10,000-mile oil drain extension (45,000 to 55,000) for engines using the new VDS 4.5 or Mack EOS 4.5 oils

​

No surprise there, in essence exactly what I wrote.

But there's also this:

Bengt says that the need to gain fuel economy improvements while extending oil drain intervals will be key drivers for the next Volvo specifications. “The current Volvo VDS-4.5 specification, which was introduced in September 2016, ahead of API CK-4 first licensing date and with more severe limits, is likely to be replaced in the first quarter of 2019. To meet our requirements we will use the base level of API FA-4 or ACEA F11 and increase the severity of the Volvo T13 test.”

Looking ahead, Bengt can see the need for another decrease in viscosity by 2025. “Yes, in the future I think we will need to lower viscosity even further to gain additional fuel economy benefits. But,” he concludes, “Volvo will not accept any compromise on reliability, durability or oil drain interval.”
​

With regard to Paccar, all engines can use any CK-4 oil so it seems. FA-4 oil is not yeat approved.

 

You know what you do when you assume, you make an ### out of u and me. Or maybe they are as HARD-HEADED as you!

 

Exactly. So when I stated that FA-4 was targeted to big fleets with early trade-in cycles you now see what I was getting at. FA-4 is not about durability, but fuel mileage. How long or how you operate the truck would influence what oil one should choose.

 

I'm sorry, but your conclusion is flawed.

Engines have to be designed for FA-4 oils, and present engines have not been designed to use them. Volvo specifically states that it expects to use oils based on FA-4 in their VDS 4-5 specification.

In future they expect using oils in excess of FA-4 in a couple of years, but only if they are save to use.
