Revised Maintenance Schedule

Dear Porsche Owner:

The high performance capabilities of the turbo-charged engine in your Porsche automobile places extra demands upon the lubricants used in the engine. Because of these demands, Porsche has, as a precautionary measure, modified the intervals at which the oil should be changed.

Porsche recommends that in the future you arrange to have the oil in your engine changed at intervals of not more than 5000 miles or 6 months, whichever occurs first. You should disregard the recommendations contained in the maintenance schedule delivered with your Porsche 924 Turbo at the time of purchase.





The accompanying illustration contains the new maintenance schedule for your vehicle. We ask that you retain the Warranty & Maintenance booklet originally delivered with your vehicle as a record of your warranty rights and previous maintenance.
