Synthetic Engine Oil

[Tom Warner]

I believe that Royal Purple is NOT recommended by Detroit Diesel as
see in their publication Detroit Diesel Lubricating oil, fuel and
filters http://tinyurl.com/32txa4

What is interesting is that both Mobil Delvac 1 and Mobil Super 1300
is also recommended. I have used Mobil Super 1300 for some time in
my old Cat 3208, my diesel tractor, and all my vehicles. It is a very
special oil and very heavily used by truckers as it can now be found
in almost any truck stop I have been in while travelling and in
Walmarts at less then $7/gallon and auto parts stores.

In my opinion for the few miles that we travel in a year I think
synthetic oils are a waste since the drain intervals are not
increased with them. Average coach owner travels 5000 miles a year
and then changes the oil.
