How are you measuring the oil used?� 
Are you measuring oil added and removed during an oil change? Or� checking the stick?
I ask because I have a Ford with a z-tech family motor.� I have found that the dip-stick is the only undependable thing on it.� Example: I am showing my 10 year old how to check oil, "Son, this is how you check the oil on a car". I pull the dip-stick and the�pull bar�breaks off of the stick.� I have to remove the old one that has now slid down into that little pipe. I buy a new one for $22 and 6 months later I check the oil and the tip--right where it says "full" has broken off,� is now useless and the tip is laying in the oil pan (�I hope). I bought a generic dip-stick�at a FLAPS. I rarely check the oil. At 14 years and�123,000� miles it doesn't really use any. I find it to be a really good engine that needs almost zero maintenance except for the timing belt and that was only $124 installed.� The only way I'd ever own a Vanagon is with a z-tech. Not because they are a good, cheap engine, but all the stuff around the water boxer is getting
 older and some of those parts are no longer available from the dealer.�You can't run a daily driver and wait 10 days for a special part from goWesty.
Sorry if this sounds like a Ford Z-tech Forum.

Zetec Using oil

Bostig records show the engine they installed in my 85 Vanagon had 24K
miles on it.

It's using oil. After about 2500 miles I've put in 1 quart. The engine
is not leaking oil, no smoke is coming out the exhaust, and the coolant
does not have oil in it.

Is there a way to determine how the engine is using oil? And id so, what
is the fix?
