Common Weaknesses & Maintenance Notes

The MR20DE is widely praised for its longevity and low failure rate. However, typical issues may include carbon buildup, oil consumption at high mileage, or timing chain noise due to wear.

These are easily prevented with regular oil changes (5W-30 or 5W-40 synthetic), quality fuel, and timely filter replacements. Keeping the EGR system and throttle body clean ensures consistent performance and fuel economy.
