Underrated Tips to Maintain Your Engine
1. Use High-Quality Synthetic Oil.
This reduces wear and keeps internal parts cleaner.
2. Replace the Oil Filter Regularly.
Dirty filters reduce flow and protection—always opt for OEM oil filters.
3. Keep Up With Spark Plug Intervals.
Worn plugs lead to misfires and poor fuel economy.
4. Keep The Engine Bay Clean
A clean engine bay makes it easier to spot issues early.
