    If it has CJ is it ok oil? IF it has SJ is it ok oil? At the Branson meet the fellows said CJ oil was ok But if it has SJ on the packaqge it is bad oil for Studes. What is the story on these designations????[?]

      CJ is the new low-emissions diesel & does NOT have zinc in it - I wouldn't run it in any of my older cars.

        Ernie how about SJ. Can this oil be used when no CJ is on the container???[?]

          SL & SJ are current ratings for gasoline engines. This means they're designed for modern production engines with low emissions - you can read that as "no zinc" for emissions. So again, I wouldn't run them in old flat-tappet engines.

          Coming due on an oil change in the Stude - will have to see what's available locally now as my last bit of CI oil is now gone.

            Found some Castrol Diesel 15w-40 CI-4 oil at O'Reilly's auto parts so went ahead and cleaned out 3 of their stores to the tune of 56 quarts total. They did not have any cases of it so it too must be going away. This should hold me for a couple of years for 3 cars. Maybe by that time something else will come along like the Castrol Classic I'm hearing about.The Castrol facts sheet behind the counter in the store did not mention it.

              I went to a Tractor Supply i bought two 2 1/2 gal cans and 3
              quarts besides the 8 one gal cans i have already old shell rotella.
              What is the shell life of motor oil?does it need to be kept
              in a climate controled area?

                For any fellow Canucks out there I just found a shelf full of Rotella-T 15w40 in CI version at my local Canadian Tire (London). I had the fellow check and they still had cases of it in the back.

                  Just a side note to this thread; I have been running the 5W40 Rotella synthetic (old stuff) in my 944 and it's great in the winter but on a 90 degree day with the A/C on I'm noticing that it thins out more than I'd like. Porsche specs a 40 or 50 weight oil for that engine and I think next summer I'll be running something else as pressure drops as low as 3 bar (45 PSI) at highway speed. I mentioned this on a Porsche-specific forum and got a couple replies from guys with 951s (the Turbo version of my car) saying that they can't run it for the same reason but that other oils (e.g. Mobil 1 5W40 or 15W50 syn.) didn't seem to cause the same issues.

                  I don't know if this is a real concern in a cooler running Stude engine or not, but I'll be looking for a thicker alternative. In normal driving in my Studes I have not seen any oil pressure issues with the regular dino 15W40.

                    The oil itself might remain usable for decades, however the plastic containers that most oil now comes in will likely get brittle and split open with age long before the contents significantly degrade. Much better to just use it up with regular oil changes, than to have to clean up an oily mess all over your shelves, workbenches and floors.

                      I was looking at all the different 15-40 oils in the local Autozone today. Most were CJ-rated, but Autozone's private brand is CI-rated- ~ $8.00 a gallon (FWIW).

                        I'll have to take another look, but I think Tractor Supply's private brand CI-rated 15-40 is available in five-gallon steel cans.

                          I have an e-mail from STP.....they claim one bottle has more zddp than one gallon of oil.

                          quote:Originally posted by Flat Ernie

                          STP oil treatment says it contains ZDDP on the bottle - how much is anybody's guess. I don't know anyone who has done any testing on it.

                              Still driving my 86 grand marquis daily.....love those big azz fords!

                              this whole situation frosts my cookies. Yes six bucks a quart is acceptable for a classic car, but what about my 20 year old daily driver?

                              I realize that "most people" don't drive 20 year old cars on a daily basis, but up until about two years ago I was actually driving it to work every day, and I know I'm not completely alone. (would still be doing it if I didn't have a company car.) ISTM that we're reaching the point of diminishing returns with all these new enviromental laws, and it's putting the squeeze mostly on those who choose not to or CAN'T AFFORD TO buy new cars, that is, those who can't afford to be squeezed.

                              OK, rant off. back to your regularly scheduled programming.

                                Here's some more fuel for the fire.... I had a short session with someone on a newsgroup about the oil thing and he replied...
                                ----
                                A CJ/SM oil that also carries ACEA A3/B3 or A3/B4 approval will
                                work perfectly well in a "vintage" engine.

                                Since API dropped the flat tappet wear tests from their test
                                sequences and ACEA did NOT drop the flat tappet wear tests from
                                -their- test sequences, it's simply a matter of understanding
                                which oil testing sequences are worth paying attention to and
                                which aren't. API aren't.
