GMC recommends having your 1984 GMC S15’s motor oil changed at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your S15 may need its oil changed ASAP if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or notice excess vehicle exhaust.

More frequent oil changes generally won't harm your GMC S15. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.
