Why do so many Americans hate European trucks?

@Caesar favorite type of axle configuration too!

 

Every single weekend I think about America.

 

btw. I just reminded a nice Polish quote.

Try to explain to foregin guy, why in Poland 1 bottle of alcohol is just perfect, 2 is to much, and 3 is not enough.

 

guess his future profession?

 

We need to say a prayer for @Cat sdp .
He is sick.
Lost his mind.
In another thread he advised someone to get a ............MX13.

I fear for his sanity.

 

No, I advised to stay with 13L for city work......

I didn’t use the MX name he did. I avoided that discussion.........

I’d get the Cummings 13L if I had to be weight sensitive....

 

I advised a 11L.
Truck is for city work so emissions play a big part.

 

Was playing around with the new Daf truck configurator and we can now get a filter on the cooling circuit.
Combine that with what i have learned about other bits off the engines (like the crankcase vent module) and it is fair to say they are making the EU and USA versions as similiar as possible.

 

No, the clinging to metal comes from specific properties of synthetic motor oils.

This is a quote from Exon Mobil:
"One key to film strength is the polar molecules of the Synnestic diester base stock. These molecules line up on metallic surfaces like the nap of a carpet, creating a strong lubricant film that helps prevent metal-to-metal contact."

You're absolutely right that the smoothness of the surfaces also plays a role. In the good old days engine parts like crankshafts and cylinder walls were quite rough when they were new. Breaking in the engine meant making those surfaces smoother by wear. It also meant that the space between shaft and bearing became bigger after breaking in the engine. To fill up that space, a thicker oil was needed.

These days production of these parts have much improved, the metal surface is much smoother. Breaking in a new engine is hardly necessary, and the space between shaft and bearing is smaller, so that you can you use oil with a lower viscosity.

Thinner oil penetrates better, if you have a rusty bolt, you put WD40 on it, it is a very thin oil that penetrates very good. Putting a few drops of 15W40 on it won't help.

The tendency in the engine and oil industry is clear. Low viscosity high quality synthetic oils for reduced fuel consumption. For new car engines 0W20 is normal, for truck engines 10W30 and 5W30. Perhaps in five years or so we will see 0W20 oils in trucks as well.
