    15W40 Shell Rotella diesel oil. That's been recommended both here and in the Turning Wheels advisory column.

      OK...nothing personal, and TW's is always up for challenge.....I've been told, and believe that 15W-40 oil starves the engine on startup ! I believe 5W-30 does not. I use 5W-30 in winter, 10W-30 in summer. My engine is a 18K rebuilt Stude V8. I believe if your engine is an older, used mill, you'll have a tougher decision. Do you accentuate the starvation at startup (clogged passages, low oil pressure, etc) with the thicker oil to get decreased oil consumption and leakage....? You decide. I change my oil every 3K miles....I believe at that rate I'm "wasting" oil and the planet, but I'm making up for it in other ways...

        If your oil pressure is in spec hot with a xW30 motor oil there is no problem with that plan. However the Rotella has a lot more detergents and anti-wear additives than your average, everyday motor oil. So you pays your money and you makes your choice. I like the Rotella as it seems to do a great job cleaning up sludgy old engines.

        If your engine is leak free, and has good oil pressure with xW30, a synthetic might be the best choice.

          Also keep in mind that a 15W40 still flows better than a straight 30 weight when cold, which is likely what these engines were designed around...

            I use the Rotella Synthetic, which is a 5W-40, in everything. You can use the Dexron-3 in the P/S without worry.

                5W-40 Rotella is not in our Wall Mart store. My choice would be a 10W40 for weigth however I recall in the 1980's that the 10W40 and the new high(190) temperature thremostats had varnish build up that caused ring problems. The reason given was 10W40 has twice the viscosity index improvers as does the 10W30. I was not aware of 10W40 being a problem in the 1950's and 180 was the typical high degree thermostat of that day. Anyone have any insight into this?

                  Its not the same oil. "Recipes" have change over the years.
                  Shell Rotella 15w40 is the way to go. Like N8 said, it has additives that extend the life of and cleans crap out of old engines.

                    I use Shell Rotella 15-40 in my 72 year old unrebuilt Rockne and have used it in my rebuilt 289 since day one. The Rockne uses oil but the 289 hasn't burned or leaked any in 18,000 miles.

                      Okay, I understand the Rotella 15W40 is great for cleaning out old engines. What do you guys suggest for a newly, and completely rebuilt Studebaker six? Mine is in a machine shop now, about to undergo a complete overhaul.

                        I'd use it in a new engine too. But thats just me.

                          I would probably break a "new" engine in on Rotella and then switch to Mobil 1 Truck & SUV formula 5W40 or Rotella syn. 5w40

                            Just to add my 2 cents, I switched to Castroll 20W-50 in my '59 Lark VI and noticed an improvement in my engine's running. Maybe it's my imagination but the car runs better and maintains oil pressure well.

                              I dunno if 20W50 will really help the engine run better... you will get more power with a xW40 or xW30 so long as the engine maintains sufficient oil pressure, which really isn't all that much. As long as it's measurable at idle, and 50-60 lbs on the highway, you don't need thicker oil.

                              Of course, you are in the best position to determine what's best for your car, so you'll just have to find what it likes.
