Not to be too much of an alarmist, but...

This particular motor (and some say 99's in particular), tends to use oil.
The oil level should be checked at every fill up & the PCV valve ($3-5.00), should be changed every other oil change.
The result of not staying on top of your oil level, is motor replacement, no if's, and's or but's...

Use the handy search function using "oil consumption" for more...
