Default 2015 FLHTCUL fluids

I just purchased a 2015 FLHTCUL. The guy didnt have a manual for it and I'm wanting to do a 3 hole oil change asap. Does anyone know the exact capacities for it? 2015 FLHTCUL

This is from the owners manual of my 2016 RGS. Same power plant. FYI, you can go onto the HD site and download a free manual for your bike. Be sure to read the asterisks!

I am an AMSOIL dealer and was using it long before I was a dealer. Of course I will say use AMSOIL SYNTHETIC, but use synthetic. your bike will be happy you did.

Be careful when following oil capacities shown in owners manual, don`t just dump that amount in or you will have an overfilled oil reservoir...

Start with 3 quarts, run for a few minutes and see where the level is at.

I was sure to underline that in my post hoping he’d see it. The asterisks are in the manual for a reason. Usually just the 3qts is enough to get me back to about 2/3 on the dipstick which is where I leave it. Only get a little bit of blow by on the bottom part of the filter and it never drips.

Agree entirely. Each reservoir has a level to fill to, specified in the manual. If the manual says 3 quarts, you need that amount to hand before you start, but may find there is a little left over afterwards! Be especially cautious when filling the primary.
