I went to SAE 40 Royal Purple because I think it is an oil consumption issue
related to engine speed and going to a single viscosity oil might help. This
may be wishful thinking but I had a chat with the manager of the NAPA store
where I bought the oil and the Royal Purple customer service engineer and
the consensus that it would be worth a try to see what happens. If it didn't
help it was an engine / ring / valve guide issue.
The engine in Double Trouble was rebuilt by Ken Frey about 50,000 miles ago,
had no sludge in the valve covers when I replaced the gaskets, no sludge in
lifter valley just the "normal" burnt on crud when I swapped over to the
aluminum manifold, and virtually none in the crankcase when I replaced the
single drain oil pan with the dual drain.

you are aware that it takes some time for all the oil to run back to the pan
so when you stop for gas your oil will always read low for about 20 minutes.

i've had consumption problems since buying my coach in '06. i first went to Mobil 1 oil with no change. since then i've changed the intake valve seals to the "positive seal" type, changed to the proper PCV valve, changed to the correct valve covers, calibrated the dip stick, all with no change in oil consumption. my engine was rebuilt 20K miles ago by the PO. i suspect a bad rebuild, probably rings or loose fitting pistons. i gave up and am looking for an engine to build and have ready when needed.
