Subject: Burning a few quarts of oil per 1500 miles

I've just seen a beautiful 35 ft. 1981 Blue Bird Wanderlodge FC and I'm thinking about buying it. It looks like it's in great shape (although I haven't seen it in person) but my only concern is that it burns a few quarts of oil every 1500 miles. According to the owner, it doesn't leak any oil though. Is this something common or something to be concerned with? It has about 160k miles without a rebuild on a 208 CAT Diesel FC (forward control) engine, 210 HP.

Any advice would be great!

According to Caterpiller, 2000 miles to a gallon of oil is verging on excessive oil useage.

It is not uncommon to consume oil in a CAT 3208 NA or Turbo. Recently I switched from Shell Rotella to Mobil Delvac 1300 Super. In this process I noticed that the engine smokes considerable less and I am consuming far less oil. I own a 1982 FC with a CAT 3208 210HP NA (Naturally Aspirated) engine. I think that keeping the oil real fresh is vital... How many miles are on the engine? and has it ever had a the rings serviced? what oil is being used?... Back in the early 80's diesel had far more sulfur in the fuel and that pitted and ate rings and sleeves, this is why when you notice much smoke, a loss in power as well as large oil consumption -- it's usually ring and/or sleeve time...

I remanufacture lots of these engines. They are parent bore engines (no clyinder liners). Your piston to wall clearance is excessive. Block must be bored for over size pistons. While you sre at is install a roller cam and roller lifters
reduces friction and increases power.
