Synthetic vs. Dino

[Jeff Miller]

If your engine rebuilder gave you special break-in oil change
requirements (shorter interval), use the cheap oil to the first
change. if not, you can change at any time, breaking in an engine
with syn oil in it is fine and recommended by Mobil.

Dino is fine, synthetic is better. Holland Motor Express used to run
Mobil Delvac 1 in their 6V92 fleet, changed it at 250,000 miles
during a major maintenance, filters in-between. I don't know if it
has changed, but last I knew the Delvac 1 has no viscosity modifiers.

Synthetic trans fluid I highly recommend as it has a higher thermal
transmissivity and will run cooler, one reason it is popular with the
towable-RV crowd, it made a noticeable improvement in trans temps
during retarder use in my '88. ZF allows triple the maintenance
interval with synthetic trans fluid over conventional/dino fluid.

Lots of money, and as many will argue the coach will run fine without
it.
