Since a lot of us bought some great deals on synthetic motor oils, what are your oci going to be? 1. Earlier 2. More or less your normal 3. Extended Mine is #2 since I have a lot $.50 MC and free Durablend to use up before I get to the $1.00 GC. Once I get to GC, then #3.
With Esso XD-3 0W30, 25,000 miles/40,000 km's or 5 years, whichever comes first, in my 1992 GM 3.1L V6 engine. A typical year is around 8000km of driving for me, so the mileage and time work out relatively well. With the high TBN of the XD-3, I have no qualms about neither the mileage nor the length of time.
