  • You read it first in Turning Wheels

    From the News Group:


    The June 2006 Hot Rod magazine has an excellent technical article on
    why flat-top lifters and their attendant camshafts are failing at a
    dramatically-increasing rate of late. It's worth a read if you have the
    time.

    One (but not the only) reason cited was people using current S-rated
    motor oil designed for new-car engines, none of which (they say) have
    the flat-top lifters and camshafts that were the industry standard for
    a hundred years, and are in our Studebakers.

    Hot Rod's research points out that current S-rated oils do not have
    enough zinc and phosphorus compounds to properly lubricate flat-top
    lifters and cams. They recommend diesel-rated oils, using Shell
    Rotella-T as an example.

    Chemical analysis is given for the requirements of current S-rated oil
    versus C-rated oil (C = Compression Ignition, i.e; Diesels). The
    analysis indicates C-rated oils have between 50 and 60 percent more
    zinc/phosphorus compounds than do new-car S-rated oils.

    Shell Rotella-T, of course, isn't the only appropriate oil meeting
    those standards. Chevron Delo-400 is another such oil, as is Castrol
    Tection Extra. Incidentally, Castrol Tection Extra is on sale at Auto
    Zone for $2 off a gallon jug through May. It's regularly $8.79 a gallon
    here in Central Indiana, but the register rings you up at $6.79 through
    May: Limit two gallons per customer per day.

    Remember, we discussed this oil situation in The Co-Operator some time
    ago...so get your news first in Turning Wheels <G>! (I'd appreciate it
    if any of you computer techies would patch this thread over to the SDC
    Technical Forum as well. Thanks. BP)

    Thanks for this information! It is only the second time I've heard this, but I don't doubt it at all. Allowing reformulated motor oils to be marketed, yet not making it widely known to the general public, could almost be considered to be another tactic "they" are using to get old cars off the road.

      Thanks for pulling this over here, JP. One of these days, I'll figure out how to do it myself. [:0] BP

          In the last 3 weeks I've changed the oil in my 1962 hawk and 1966 cruiser and put in the 15-40 Shell Rotella - T. I got the oil in gallon containers at Menard's for under $8.00 each.


          I've read that some Studebaker owners recommend it for newly rebuilt engines as well as older, less fresh, engines. I think I did the right thing!

            Even better, if you have a fresh rebuilt engine, you can get a synthetic version of either Delo or Rotella in 5W40 in gallon jugs at Wal-Mart. I've been running this in my Porsche and will probably run it in the '55 as well after it's been broken in.

              I'm curious. Does this information apply only to the V-8 Stude engines or does it apply to the six cylinder engines as well?
              I do remember reading about this in the "Cooperator" section of Turning Wheels, but don't remember is they spoke about the sixes.
              Up to now, I've been using Castroll in my '59 Lark VI.

                Personally, I would run a "fleet," "Heavy Duty," "dual-rated" whatever you want to call it in ANY car for which a 15W40 is an acceptable viscosity. I'd use the synthetic version in any engine that didn't leak or burn oil. Oil is cheap, engine rebuilds are not. As an added bonus, the HDEOs aren't any more expensive than the regular oils, sometimes even cheaper. Besides the anti-wear additives already mentioned, they also have high detergent content which means that they will keep an engine cleaner, even if it is driven in conditions that promote sludge (short trips, etc.) or has a lot of blowby and therefore particulate contamination of the engine oil (Diesels tend to put a lot of soot in the crankcase after the yget a few miles on them.)

                  ANY engine with flat-top lifters, which is just about anything before roller lifters got phased in during the 1980s and 1990s!

                    For those who prefer Valvoline, the Valvoline product with the appropriate specifications is "Valvoline All-Fleet Plus Motor Oil." [8D] BP

                      One of my little peeves (easy Gary...easy)
                      Shouldn't they be called 'flat bottom' lifters
