I installed a Provent 200 at 8,000 mi (all miles rounded to nearest '000) and recently changed the oil and emptied the Provent drain line at 52,000 mi. To date I have collected 18 oz in a 3 cup sealable clear plastic container. I estimate that less than 5% of the fluid collected represented moisture. The volumes drained ranged from 2-3 oz except for one of 4 oz.

Since installing the Provent, the oil has been changed 7 times at intervals ranging from 5,000 mi to 7,000 mi. The oil weights ranged from the 1st two 5W30's from GM "freebies", one prior to Provent install, to experiments with one 0W40 and two 5W40 oil changes. The last three, and expected all in the future, were and will be Castrol Edge Euro Car Dexos2 5W30.

I, and I trust others on this forum, would be interested in collection results from other oil/air separator installations regardless of brand and mileage.

You "trusted" correctly... Thanks for posting the results.
