Keep a quart of your chosen 0w40 full synthetic oil on hand, especially if your vehicle is known to consume oil. This prevents you from needing to mix different brands or types in an emergency.
If oil consumption becomes excessive or you see smoke from the exhaust, consult a professional mechanic. This could indicate a more serious issue requiring diagnosis.
Common Problems with 0w40 Full Synthetic Oil NAPA Users Might Encounter
While generally reliable, there are a few things to keep in mind:
- Higher Cost: Full synthetic oil is more expensive than conventional or synthetic blends. However, its extended life and superior protection often justify the investment.
- Seal Compatibility Myths: Older myths suggested synthetics could cause leaks in older engines. Modern synthetics are formulated to be compatible with all seal types, so this is rarely an issue.
