check the oil level on the dipstick and record the reading. change oil and filter under the normal maintenance procedure. note the condition of the oil. does it look like the oil has been changed at the proper intervals? arrange visit with the dealership every time the engine needs oil for the duration of the test. at every visit, the oil consumption sheet must be filled out including mileage, date, amount of oil added and the technicianis initials. for a proper diagnosis, the amount of oil consumed over a known mileage should be checked three times and then averaged.the accumulated mileage divided by the total amount of oil added will give the consumption rate in miles per quart . if the oil consumption rate is greater than 1000 miles per quart, further diagnosis may be required.
