You don't need to be a mechanic. A few five-minute checks keep your car reliable and save you money.
Check Your Oil
Once a month: park on flat ground, pull the dipstick, wipe it, dip it again. The level should sit between the two marks. Most cars need fresh oil every 5,000 to 7,500 miles — your owner's manual says exactly.
Check Tire Pressure
Low tires wear out fast and waste gas. Check monthly with a cheap gauge, before you drive. The right number is on the sticker inside your driver's door — not on the tire itself.
Quick tread test: stick a penny in the tread, Lincoln's head down. See the top of his head? Time for new tires.
Lights and Wipers
Once a month, walk around and check every light: headlights, taillights, brake lights, signals. Burned-out bulbs are cheap and take minutes to swap. Wipers streaking? Replace them. Five minutes, no tools.
Peek at the Fluids
Pop the hood now and then. The reservoirs are see-through with min/max lines. Low coolant or brake fluid? See a mechanic. Washer fluid? Just top it up. See a puddle? Note the color — green is coolant, dark brown is oil, red is transmission fluid. Tell your mechanic.
Listen Up
New squeal, knocking, or whine? Get it checked early. Small problems are cheap. Ignored problems aren't.
