IF I NEED TO TOP OFF MY OIL BETWEEN SERVICES, IS THERE A SPECIFIC OIL I SHOULD USE?
The MINI Service Information dated December 2015 recommends the following:
• BMW Longlife-01 5W-30 Full Synthetic for all MINIs produced up to and including Model Year 2015
• BMW Longlife-01 FE 0W-30 Full Synthetic for 2nd generation Model Year 2016
• BMW Longlife-14 FE+ 0W-20 Full Synthetic for 3rd generation Model Year 2016 and later.
A wise question, my MINI-minded friend. For starters, let us remind you that required maintenance work and service should be performed by your MINI dealership. That said, we suggest you check you engine oil level whenever you fuel up your MINI. If you're low, top off with MINI High Performance Full Synthetic Oil - the very oil we use for scheduled engine oil changes. If MINI Hight Performance Synthetic Oil is unavailable, we recommend using only the following approved synthetic oils. (For information on checking your engine oil level refer to your vehicle's Owner's Manual.)
If MINI High Performance Synthetic Oil is not available, you can add small quantities of another synthetic oil in between oil changes.
