Picked up a 51 2 door with minimal body rust, floors shot, but otherwise in good condition. car has been off the road for 30 yrs, last ran about 5 or 6 yrs ago.
We got the engine running and the car rolling. I rebuilt the fuel pump and carb, and she purs like a kitten running off a remote tank. Right now I am running it off a remote tank filled w/ 89 gas and a little 2cyc oil. I put that in there on the first start running when bottlefed, poured that along with a gallon of 89 into a 1 gallon tank to run from. Fuel pump pulls good and the engine idles and revs great.
Need to next tackle tank and brakes. I checked compression when the engine was cold and I had round 90# on all but one, no 3 cylinder was 70# I figure it may come around if it runs a little more. I read somewhere to check compression when warm, will do another compression test to see where we are at. Engine runs around 175 degrees idling, and the radiator hold water with a very slow leak, that will need to be addressed. all gauges and lights work, except radio.
My question is I want to change the oil, this 6cyl has no filter so its just drop oil and refill. What oil do I use can I use a detergent oil in it to try and clean it up and then change right away, of just keep pouring in non detergent? My guess is I also will need to add in a lead additive to the fuel as well as zinc in the oil? please advise.
