"Maxlife" oils are designed for cars which have experienced significant
engine wear or have other related problems that can cause oil consumption
in-between changes. Obviously, this event does not magically occur exactly
at 75,000 miles, and on some cars that have been always used a quality full
synthetic, it may never occur.

There is no danger of using conventional oil on an older car, so long as the
viscosity is appropriate, your oil level is full (or nearly full), and your
oil pressure is normal. On cars with high mileage, it is sometimes
appropriate to use a slightly higher viscosity, to allow for excessive
engine wear.
