Oil question

[Switch]

According to my manual on the '97 RSTD it shows oil quantity as follows:

 

Total amount: 4.6 US qt.

 

Periodic oil change:

3.7 US Qt

 

With Oil filter replacement:

3.9 US qt.

 

Now, If the manual shows 3.9 quarts required if the filter is changed how does that add up to 4.6 qts total?

 

But what I really need to know is, if I change the filter, how many quarts should I put in? Secondly, if I don't change the filter this time, how many quarts should I put in?

Its more like 3.5 qts. My 07 Venture takes 3 qts. to center of site glass. Don't go higher than the center of the sight glass!!! dIf you do it will be blown into the air box and it will run down the left side of the engine.

You can never get 100% of the used oil out of a motorcycle motor as the oil is shared with the transmission and there is a lot of surface area in the gears also in the oil passages.

 

I assume the 4.6 Qt is for the initial fill, or after rebuilding.

 

Like tew47 said above, fill to the center of the sight glass NO HIGHER!!!!!!
