I don't have a problem with that, and I suspect it was purely for my benefit. Before you go away though, here is what we've been trying to tell the OP.


Now, by all means, feel free to go argue every little detail with him.

 

 

Thats fine, stay off my threads.
My question was never answered
It was a question regarding a spec sheet, specifically oil being tested at 100c that I read about. I'm not an oil expert so I asked for advice. If thats to much for you to handle then back off and let someone with that knowledge answer .

I also asked for any oil tech savoy people that may be able to help which obviously isn't you with your cut and paste graph

 

Some are trying to be helpful here. Best advice I saw was use the oil that you got in a good deal in your car. I did find that on my old Harley Road King that Mobile 1 did tend to allow a little more noticeable valve rattle at stops.

 

The ASTM D445 test determines the SAE J300 oil viscosity at 100C (212 F) to determine the viscosity grade of the oil. No other testing at that temp is done.

HD recommends a 20w-50 grade oil for your engine. a 40 grade oil is thinner than recommended.
(Harley stopped selling their HD 360 10w-40 oil, but used to recommend it only when used in temperatures under 40 F.)

 

My bad. I assumed the bolded text above was the primary concern. How the hell did I ever make a mistake like that?

 

By reading half of the original post and commenting on it....glad we got that figured out

 

You bought the wrong viscosity oil.
You got a great deal on 10w40 because not many modern engines use that grade.

 

 

Guys...That's not what he asked...
