A couple of us once rode up to Montreal for the day, and then back down to Rutland, VT. for a rest. My buddy was on a '78 BMW R100 RT, and I was on my 'Wing. He was beat up, and ready to get off the bike...
I was ready to ride the rest of the way home. (Another 250 miles.)

Lap shear comes into play under extreme stress. Diesel engines have much more mechanical stresses than gas engines due to the torque generated by them. So I do not use synthetic oil in diesel engines.
.
RV dealer used 10w30 on Mercedes sprinter for my leisure travel van 25’MH
This time I used 5w40 manual said both are ok my mechanic said it’s okay in Ohio , i was in Florida’s mechanics used mobile 1 10 w 30 they say all ok according to the Mercedes 2013 blue tech turbo, so what’s the best

Shear generates heat. The more shear the more heat. So unless you have a 22 qt oil pan and a huge oil cooler, you are going to coke the conventional oil (oil temp above 270 F degrees). Synthetics do not begin to degrade until over 320 F degrees and some group 5 oil is stable to 525 F degrees (Mil Spec 7808G).
I have a Jetta 2L TDI. The only approved US oils are Mobile 1 ESP 5W30 (available at Ram dealers) and Castrol SLX gold 5W30 (available at VW dealers). Its little 118 cuin engine produces 236 ftlbs of torque @ 1,500 rpm under 26 lbs of boost, so I would say it is stressed. Oil changes (4.3 quarts) are recommended at 10,000 miles or 1 year which ever comes first.

I agree, just like Cummins generators say synthetic oil isn't necessary, it depends on how long you want it to last. They don't say not to use it. I keep things forever except for my class c motorhome. It's up to the person are you going to sell it in a few years or keep it a long time

Instead of 9 mpg I get a little over 10 MPG with Either Valvaoline or Mobil 1. I drive at 2,ooo rpm or 65 mph.
I’d take 9 mpg any day. Averaging 63 mph I only get 7.5 at best. What does yours weigh?

Isn't that a bit of a personal question?
