How often should I change the oil in my used car?
Oil should be changed every 3,000–5,000 miles for conventional oil or 5,000–7,500 miles for synthetic oil. In South Florida, oil breaks down faster due to heat. According to Omari Grant, ASE-certified mechanic at Fort Lauderdale Auto Sales, this is the most important maintenance item for engine longevity.
When should I replace my tires?
Tires should be replaced when tread depth reaches 2/32 of an inch. Use the penny test: insert a penny head-first into the tread groove — if you can see all of Lincoln's head, the tires need replacing. Rotate tires every 5,000–7,500 miles to extend their life by 20–30%.
How do I know when to trade in my used car?
Consider trading when annual repair costs exceed 50% of the vehicle's market value. Check your car's value using Kelley Blue Book (KBB), Edmunds, or NADA Guides.
What maintenance does a used car need?
Essential used car maintenance includes oil changes every 3,000–5,000 miles, brake inspections every 15,000–30,000 miles, tire rotations every 5,000–7,500 miles, air filter replacement every 15,000–30,000 miles, transmission fluid changes every 30,000–60,000 miles, and timing belt replacement every 60,000–100,000 miles if applicable.
