I recently learned that the Dyna oil capacity is 3 quarts, and all the Touring models take 4 quarts. I always thought that the 96 ci twin cam in my Superglide was the same motor used in the Touring bikes, but I guess that is not the case. I have to wonder, is a Dyna more likely to overheat than a bike with the extra quart of oil? Will my engine last as long, everything else being equal? Any other differences in the motors?

Comments?

 

Touring models weigh more and often are loaded with supplies for touring, you're ok.

 

Some pretty experienced engineers designed these bikes and tested them extensively at the HD testing facilities. I don't know why you're worrying.

 

They either compress 4 qts of oil into 3-1 qt containers before they pour it into the touring models OR they reduce it's mass by 25%. You can do a search to find out which one MoCo uses.

 

Wait. I have that backwards. They increase it's mass thereby reducing it's volume by 25%.

 

Are you sure you? I think you have add water to that kind of oil?

 

You might consider an oil cooler.It won't add much more oil capacity. It did seem to help when I'm stuck in traffic on a hot sticky day in the south,

 

You're right. It will work with distilled water but only if you keep the evaporation/condensation ratios equal.

 

The TC96 may say 3 qts. in the manual, but if you add that, it will be overfilled! Oil change with filter is really 2 1/2 qts. I know of no one who gets the extra 1/2 qt. out.

 

HotBike from a few months back had an article about adding an even bigger pan to a bagger so an additional quart could be added.
Not sure if there were details on what the temp change was -I'll see if I can find it.
