If you are near the Caterpillar dealer Toromont in NS Cat dealers have an excellent fluid analysis service with world class ISO 9001 certification. I've used the oil analysis services of Finning the BC Cat dealer many times. The cost of the sample container the service and report was about $38 last time I purchased one. You purchase the sample container over the counter in the parts department and drop the container off there when finished. You can have your analysis reports sent to you via a mailed hard copy or by email with a provision for a telephone call in the event that something is found requiring immediate attention.
You don't need to wait for an oil change since most oil analysis services also sell sample kits that consist of a vacuum pump, plastic tubing and an adapter that the sample containers thread onto. You can slide their tubing down your dipstick tube and take a sample that way.
