Air Filters & Oil Repair & Maintenance

Air cleaner/filter

• How often should I replace the air filter?

Lubrication system/oil

• My engine uses about a quart of oil every 1,000 miles. Should I be concerned?
• My engine is leaking oil past the valve cover gaskets. What should I do?
• Is it better to maintain my engine's oil level at the full mark or wait until reaches add mark to add oil?
• My mechanic says I should change my oil and filter every 3,000 miles. My owner's manual says I can go 7,500 miles or 12 months and replace the filter at every other oil change. What gives?
• What type of motor oil is best for my engine?
• I am always adding oil as my engine uses it. Why should I ever change it?
