Old Jeep drivers beware!
 

The story has been going around in Studebaker circles for quite a while
that modern oils wern't good for old engines with flat top lifters, and
now Hot Rod magazine has a story about it.

Bob Palma with the SDC put it like this...

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.

A friend's Lexus developed engine sludge, that blocked the oil pickup. He
had followed all the recommended maintenance intervals. His favorite
mechanic found an article, that described this as some sort of compatibility
problem, between the new motor oil and the "old" Lexus engine design. The
car is in Albuquerque now, getting the repairs at Lexus' expense. The
repair bill is $10,000. Supposedly there are thousands of cases like this.

I don't have more data, because the friend is more of a chef than a
mechanic. But he was pretty clear about the engine seizing up, the car
being towed to Albuquerque, and numerous calls to manufacturer reps.

Re: Old Jeep drivers beware!
 

Thanks. I know Gary will get a kick out of these.

"It can cost as much as $12,000 to replace an engine"! Heh, it cost me
$5,000 to replace a Chevy 350 with a new factory engine, at the dealer in
Fort Collins, CO. I told them to go to town buying spark plugs, water pump,
oil cooler, anything they wanted. That was in 2001. How does one spend
$12,000 on a V6 or an I4 engine?

I remember one of my first cars, a 1964 Plymouth Valiant, which appeared to
have a three quart oil pan for a while. After a rod let go I found out the
reason.
