Why do so many Americans hate European trucks?

I don't mix synthetic with dyno oil. That would defeat the whole purpose of buying the cheapest oil.

No, Wal Mart Supertech is not synthetic oil. Yes, it is specified for my engine and most others too. It's on the label what engines it is OK for.

Synthetic oil is not required for my engine. I wouldn't own an engine that required it. I view it as an unnecessary expense.

Changing oil at 90,000 kilometers might be ok for some fleet purchasing new trucks then later getting rid of them when they start having higher maintenance costs.

That's why fleets usually buy or lease new then get rid of them after 3 years. Changing the oil every 90,000 kilometers is the minimum maintenance you can safely get away with. I certainly wouldn't want to buy such a truck that had been minimally maintained.

It's all about a fleet keeping their costs down. Now the next poor sap who buys that used unit after the fleet trades it in at 3 years is going to pay the heavy price for their minimal standards.

I stand by my statement oil is oil. My engine does not require synthetic oil. And my 10 years of oil samples using many different brands of 15w40 show there isn't any real difference between the oils.

That's what I thought about DPF/EGR emission regulated trucks. They require more expensive synthetic oils. They require many things that are more expensive. And associated extra downtime. That's why I will always run older engines. Cheaper to run and maintain keeping more money in my pocket.

Someone once said that if an engine uses some oil, then at least you know the oil is getting at the places it's needed.
For European cars, an oil consumption of 1 litre per 1000 km is still acceptable. That doesn't mean it's the normal consumption mind you. So 1 litre per 9000 or 6000 km for a truck engine is fine.

That's an Acea 6 oil, and DAF is specifically mentioned in the product specification.

I also locked for Shell oils for the MX engines, and this is what I found.

For the US MX engines: Rimula R5 LE 10W-30 with the following conditions:

• normal use, idle time < 20% -> change interval 120,000 km, or 12 months, or 2250 hours.
• normal use, idle time > 20% -> change interval 80,000 km, or 12 months, or 1500 hours.
• Severe duty -> change interval 48,000 km, or 12 months, or 800 hours.

For the DAF MX-11 engine: Rimula Ultra 5W-30 (premium), or Rimula R6 LME 5W-30 (standard).

• change interval between 30,000 and 75,000 km
• for engines with Extended OCI Service Pack -> change interval between 60,000 and 125,000 km.

For the DAF MX-13 engine: Rimula Ultra 5W-30 (premium), or Rimula R6 LME 5W-30 (standard).

• change interval between 30,000 and 90,000 km
• for engines with Extended OCI Service Pack -> change interval between 60,000 and 150,000 km.

For both engines Rimula R6 LM 10W-40 is an alternative.

By the look of it, the European oils seem to be slightly more advanced (newer generation, R5 > R6).

 

Here They recommend Oils Change at 50 Thousand K's for synthetic & 40 thousand for Mineral Oil..

Interesting. I have seen more than one engine over the years that doesn't like running at the FULL mark on the dipstick, but once they get closer to the ADD mark they quit consuming.

Because we put so few miles on our trucks annually we stick to 12,000 mile intervals on the trucks, and 500 hours on the equipment.

 

Awesome. Doesnt apply to me at all.

 

Seen it many times too. Cat always you to calibrate the dipstick to the chasis on the first oil change.

 

So this is a CJ-4 oil, not a more modern CK-4 oil.

API Service Category CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines. These oils are formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, the 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. These oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API CK-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase. API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations.​

There's also an even more advanced FA-4 oil specification:

API Service Category FA-4 describes certain XW-30 oils specifically formulated for use in select high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway greenhouse gas (GHG) emission standards. These oils are formulated for use in on-highway applications with diesel fuel sulfur content up to 15 ppm (0.0015% by weight). Refer to individual engine manufacturer recommendations regarding compatibility with API FA-4 oils. These oils are blended to a high temperature high shear (HTHS) viscosity range of 2.9cP–3.2cP to assist in reducing GHG emissions. These oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase. API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use. API FA-4 oils are not recommended for use with fuels having greater than 15 ppm sulfur. For fuels with sulfur content greater than 15 ppm, refer to engine manufacturer recommendations.

Ok, but what does his MBN call for?

 

Synthetic oil has a longer life time, often twice as long as with mineral oil. So you do two oil changes with mineral oil versus one with synthetic oil.
