So the truck has been modded by my bro with a turbo that was 1k. Its had its gaskets changed, oil pan gasket included and it still somehow seems to loose a quart of oil..... now it may be due to bad oil connections but we put cheap 10w40 orielly stuff in it. Could our turbo be burning up to a quart of oil or is it something else?
Oil for my 1965 F100 240 with Turbo

Back then they just used whatever. Here I’d run 10W-40 in the winter and 20W-50 in the summer.
try mobile juan 15w50
may point to rings or if you forgot about them, valve guides

A straight 6 with a turbo is not something that you run across everyday. I didn’t notice that you are in California. So, 20W50 is another option. You could also run a SAE 40 HD or SAE 50 HD.
Yea its something that happened before they blew up on youtube with power nation lol
its def a tire burner now. We will definitely consider a 20w50.... it did use to leak a lot of oil from gaskets but thats eliminated now for the most part.I like cheap.... especially on this truck hahaha
Please post further developments. I don't see a turbo as a good thing for a 240.
Probably isnt but my brother doesnt care.... I wouldnt have done it since its the og engine for the chassis so when it blows he may rebuild or drop something else inside.
Some kind of 15w40 HDEO. SuperTech, Rotella or whatever.
Does that truck have a three on the tree?
"...lose a quart of oil....". Any time frame here?
and pics and video or it didn't happen.Yep.
It does haha, we fixed the rubber bushings that wouldnt allow for it to have smoother shifting.
Its very short probably after 3 to 4 drives. Either its not showing up on the dipstick or something else.
Are you sure you didn't crack a piston or something doing burn outs on it's maiden voyage? 
Make sure the oil return from the turbo has a straight downward slopped path with no kinks. Also, what is the oil pressure like? I remember reading that you need a restrictor orifice on the oil inlet to the turbo if it's much over 40psi. Another thing it could be is excessive crank case pressure. Is the PCV working?

There'd be smoke or drips (lots of either), no?
