I'm gonna have alot of these posts guys, so please bare with me. My dads 49 Panhead. What oil do I use for changes? Is there anything better then others? What is my fill level in the tank? This thing has no fill line markers that I can find.

TIA! Sean-

 

20-50 will work just fine.
As for brand you pick it.
If you are fussy do a 20 min search on the net, you will readily find out who makes the best oil.
Someone will point you to the Fsm and it will say 50 or 60 weight, -but that is all they had back then.
The oil tank is full when hot and 3/4 to the top, I thought they had a dip stick?

 

I think the majority of panhead owners will strongly disagree with you on that.

50 or 60 wt Valvoline VR1 is fairly easy to find at parts stores.

 

Straight 50.

 

I run straight 50 in the winter and straight 60 in the summer

 

My dads has no dip stick, its just a cap. 20-50 oil, synthetic, 50/50, regular? Just checking to see what my options are.

 

OK, - I was referring not stock parts and for sure that tank is not stock.
Dont top it off as you have a dry sump sytem !

 

Lol, ok so no topping off. How do I monitor the level then? Where should it be cold? still 3/4? Seeing a lot of different responses on the oil type. 20/50, straight 50, then 60, then VR1? lol!

 

VR1 is a brand of 50 or 60 wt

Post another pic of that oil tank from the other side...I bet it is a softail tank...which means you could put a softail dip stick in it to monitor the level

 

.Oil is a religion. No reason or logic required for most people
IDC what you( use .(as i already explained)
I was using 20-50 oil B4 HD ever said it was OK and that was back in the 1970s when Penz oil first came out with it,
Nothing has blown up yet.
It just a better oil..(not necessarily Penx oil)
If you want to discuss it, I think there is a page on this forum just for oil and oil wars.
You ck the oil hot .
Engine off so you don't get tattooed.
