Re: Oil change

Not sure about previous oil used or existing type in it but it is dirty and needs to be changed.
Up until now it wasn’t driven much.
I’ve put about 400 miles on it this summer and had to add about a quart of 30 weight low detergent oil about every 100 miles or so. Don’t know about the sludge situation but as mentioned it runs great with good oil pressure on the original gauge. I’ve got the original owners manual and a 1937 shop manual and neither one mentioned an oil filter. Penngrade 1 sae 30 seems to have what needs.
Any thoughts?
Thanks
