Oil check

In a car it gets churned into foam and destroys the engine. My experience in motorcycles is it pushes out into the Airbox making a mess and potentially ends up on the ground. Not sure on the rocket

Sure. In a wet sump engine all that is correct. But the Rocket is dry sump. Any excess oil remains in the tank (within reason). I'm not suggesting anyone massively overfills it. Just saying that half a litre too much oil is better than half a litre too little.

The issue with putting in way too much oil is that as it heats up, it expands a little and as Turbo put it, you don't want hot oil overflowing all over the place onto the rear tyre or on your legs.
 
Yes It’s too bad you would think dealers should be the best and know the bike the best.
I tell you when I lived in Seattle cycle barn Triumph was great never had a problem. And never felt like I was over charged
For any work they did.
Well one Daughter is in Seattle and the other in New York so see where they both settle down hopefully close or the same place and perhaps we will move back to the States.
 

Yep that's true, that's why I said as long as it's on the dipstick I don't care. Have you measured the difference in ml between the high and low mark? It would be interesting to know. I haven't because it goes from the low mark to overfull with a small pour. If you're working your engine that hard that an extra 1/2 litre? of oil in a dry sump system holding 5-6L is going to make any significant difference you should probably be considering an oil cooler.
 
Just changed my oil last weekend. Bike up on the Becker stand, 3 bungs out, oil filter off, smear new oil on rubber gasket on new 'Amsoil" filter and install. Pour in 5.3 litres of 'Amsoil" 10w/40 synthetic oil...start and idle letting filter fill up, turn motor off, check level with plastic tie and compare level against dipstick. Sits between the two lines..perfect!!
Will do me now at 10,000kms until 16,000km service. Then i'll do it all again. Too easy!
 

6. Warm or cold maybe?
 

You forgot to soak the bread and hang it on the trees.
 

I know some MB vans run Renault engines, and service intervals on those are 20/25 thousand miles, or two years.
I know that, cos I have one in my van.
No idea about car service schedule.
