Oil Maintenance & Service Tips
Check engine oil level every 1,000 miles or monthly. Park on level ground and wait five minutes after turning off the engine for accurate readings. Add oil if the level falls below the minimum mark on the dipstick.
Always use manufacturer-approved oil filters during oil changes. Replace the oil filter with every oil change to prevent contamination. Use a torque wrench when tightening the drain plug to avoid overtightening. Inspect the drain plug gasket for damage and replace if necessary.
Synthetic oil provides better protection in extreme temperatures and extended change intervals.
| Driving Condition | Oil Change Frequency |
|---|---|
| Normal Driving | Every 7,500 miles or 12 months |
| Severe Driving | Every 5,000 miles or 6 months |
Severe driving includes towing, extensive idling, dusty conditions, or frequent short trips under 10 miles.
