It's Rotella T I use in my Studes. The fact it's diesel rated means it
has additives that protect the allows used in old engines. Modern oils
don't have them (or have different ones), and things like cam shafts and
lifters tend to wear out much faster than they should.

My Jeeps are still at the stage of when they are down a liter, it is
time for a change.

I have always been partial to Shell products on the grounds that if it
was good enough for Enzo Ferrari it was good enough for me. Rotella is
a "goes both ways" oil, meaning it is okay for both gas and diesel
engines. Shell has other products for diesels exclusively (Rimula)
which I think are better diesel oils. They are high ash content which
doesn't bother diesels but is not acceptable for spark ignition
engines.

I prefer ashless dispersant oils for spark ignition engines where oil
changes are done regularly and which burn any substantial amount of
oil. If regular change isn't guaranteed or the engine is tight and
burns very little oil I think Rotella is in fact a good choice.

Synthetic oils are good and necessary in extreme environments or in
fleet conditions where engine oil is monitored and not changed,
especially where bypass fine filtering is used. For "consumer" use in
normal conditions I think they have drawbacks.

Your mileage may vary.
