Putting my engine back together this week. What oil do you feel is best for a V-12 running in a warm climate -- Central Texas? I have gotten answers all over the board on this one. My mechanic feels that a 30W would be best to start with in the fresh engine.

Given your warm/hot climate I don't think the viscosity is as important as being sure to prime the oil system before starting and running at sufficient rpm so rings will seat properly. Also be sure not to let choke close during break in. I would make multiple oil/filter changes during this period as well.

30W for the break in period (500 miles) and 40W after that. I have put 150 miles a week on my 48 Lincoln since the rebuild and getting it running 6 months ago and it hasnt leaked or used any oil yet. make sure you follow the break in procedure recommended in the Lincoln manuel. mine heats up and vapor locks after 40-50 miles of bumper to bumper rush hour traffic but the engine stays around 200. Im going to add an oil cooler when it gets back from the top shop.

Dear Pandamarie,Oil cooler?What kind of shape is the radiator in?Why not try to get the water temp. down with a wetting agent or pumps with the re-designed impellers.I Do not know where you would begin to plumb an oil cooler on one of these cars,did you ever see how much oil flows through the oil filter ?How much oil do you think is going to flow through a cooler?Seems to me that it would make more sense to try and reduce the water temp thereby reducing the temp. of the WHOLE powerplant.Just my 2-cents.diz <img src="http://www.aaca.org/ubbthreads/images/graemlins/laugh.gif" alt="" />

Thanks for the input. I am going to use 30 for the first round anyway. We didn't have to do anything to rings and valves, just the crank and new gaskets, plus rebuilding the water pumps, new plugs, wires, coil, etc. Had the crank machined to add a real seal, carb rebuilt and new points. As it was running pretty well going into the shop, and had not had a tune up or really been on the road in at least twenty years, we got lucky. It appears that it was rebuilt once, I am guessing by the Ford Red engine paint, that would have been in the 1950s. Hope to listen to it running by the end of the week. Thanks again,

Ace
