New Years Oil Thread 2011

Hey, what's the New Years with out an oil thread. Yeah, the first oil thread for 2011. Here it goes, and Happy New Years:
I've been have a hard time starting the 240D. Its been a combination of problems. I though it might be the battery. I bought the car a few years ago, and I think the battery was replaced by the PO around that time. The battery was draining down to 12.5V. The Glow Plug light would work sometimes. So, I replaced the battery. They ain't cheap. I got an Interstate. Anyways, still had that problem, so I unhook the battery for any amount of time. I need to replace or repair the Glow Plug relay. Anyways, the car started better and I was happy.
I know its suppose to be an oil thread. I'm getting to that. The car started OK, till the cold weather set in. I did put it on the block heater and that helped. Then the snow came with the salt. So, I took the 240D off the road for a few weeks. Plus, Christmas vaction I take my Ford Contour on long trips. It did OK. I am also working on a Jeep Cherokee to get it back on the road. Some body work and mechnical as a tree fell on it.
OK, OK, now for the oil part. Yesterday, sine it rained over the weekend and washed the salt off the roads, I decided to drive the 240D to work. I put it on the block heater. The GP light worked. It didn't want to start. I cranked and cranked. Then cranked and cranked again and again. It finally started. That was on 15W-50 oil. I think Rotella. I was a bit low on oil, so I decided to replace it with 10W-40 Rotella. I bought two 1 gal jugs. I changed the oil last night. I didn't have a new oil filter, so the old one was kept in there.
This morning it was still cold. I did put the block heater on. The GP light didn't come on. Still, the engine turned over and it fired right up. The manual deos state that you can use the lower viscosity 10W-40 in lower temps. I think below 40F. Its suppose to snow Thursday, so the 240D will be off the road again.
I do know many are using synthetics with good success. Also, I do run synthetics in other vehilces. Its just that the 240D uses ot looses to much oil at the moment. There are other problems to attend to before I can pull the engine and reseal it.
I hope to get the windshield and rear quater window in the Cherokee this week or weekend. Hope to run it over the next few months, then probably sell it. Its a long story, in itsself.

if the oil has a C rating, it should be OK in your 240. you could also try a single quart of synthetic in the mix if it gets too cold for dino. even a little synthetic will help some.
but get the glows fixed for the best starting.

My starting was completely effortless once I changed to 5w (50, 40? I can't remember) oil in the wintertime. Rotella makes it. When I was using 15w, it would really fight to even crank.

Matt,
That should be a synthetic oil. The GPs worked over lunch. Yes, I will need to get them working right. I did replace them with new ones. I am fairly sure it is the GP relay box. I have opened it and looked at it. I think I saw a website with diagrams or such to repair them.

I don't actually have the car anymore. What I meant was: it would always start (all my GP's always worked), but when using the heavier-weight oil, it seemed the the starter was working really hard just to turn the motor. I'm sure the 20-something year old starter played into that, but once I switched to the lighter oil, it had no problem getting the engine spinning. Not nessesarily what you're getting at, but it does make starting much easier (when you don't have electrical access for a block heater).
