93 SW2 consuming oil

I know early Saturns use oil. Mine goes through a quart every 500 miles. But it happens strangely. I check it every few days, and it drops slowly for 3 or 400 miles, then suddenly goes to below a quart low. There is no visible smoke out the exhaust, and I put dye in the oil and there were no major leaks anywhere. My mechanic suggested I switch from Mobile 1 synthetic to a 10-40 regular oil (he said synthetics get consumed faster).

Any ideas why I am losing oil, and what to do (by the way, my 1999 SW2 doesn't use ANY oil).

Thanks for any help you can give me

By the way, I recently put in a new PCV valve, then replace it with an original equipment Saturn valve.

Are your oil pan bolts tight? I ask because sometimes they loosen up with age, and can lead to oil loss that might not be readily apparent (at least not in your driveway).

IIRC about the oil level not appearing to be evenly representational of the actual levels, it was something to do with the area the dipstick reads being funnel shaped. I think Kirk used to be up on this topic - maybe he will chime in. For example if you see the stick at about half-way, it seemed to take more than a half-quart to return it to full.

My 97 was much better at using less oil after the rebuild (new rings, cyls honed and new valve stem seals) and I could still cause the level to drop depending on how 'Spirited' I drove it. My usage also went up when I switched to synth and I went back to dino oil but changed it like every 2000 miles.
