ENGINE OIL AND OIL FILTER REPLACEMENT INTERVAL

Due to heat generated by the turbocharger and carbon deposits contained in exhaust gas, the oil in a turbocharged engine will deteriorate faster than the oil in a naturally aspirated engine. Therefore, special care should be taken to use the proper grade oil and to monitor oil deterioration.

Under normal driving conditions, the recommended oil and oil filter change interval for turbo vehicles is every 3,750 miles or four months, whichever comes first.

However, for vehicles driven in conditions beyond normal, such as racing conditions, the oil and oil filter may require more frequent changes.

RACING-TYPE DRIVING
Racing-type engine stress doesn’t only occur on the track. Racing-type driving takes place when the drivetrain, suspension, and other vehicle components are used at near peak capacity. Any driving where the engine speed is kept high – either by using lower gears at higher speeds or by employing engine braking – is considered racing-type driving.

Important: A “track day” or autocross event requires an oil and oil filter change immediately before and immediately after the event. Make sure to check other engine fluid levels as well.

ENGINE OIL LEVEL
Check the oil dipstick periodically to make sure the oil level is within proper range, which keeps the turbocharger properly lubricated and cooled. More frequent level checks are necessary especially when utilizing engine braking, because this increases the engine’s demand for lubrication.
