Check Your Oil Level
Engine oil is the lifeblood that keeps metal parts from grinding themselves apart. Reading the dipstick takes two minutes and can catch a slow leak or burn long before it wrecks the engine.
Oil lubricates, cools, and cleans the moving heart of your engine. Run low enough and those parts starve, overheat, and can seize — turning a cheap top-up into one of the most expensive repairs a car can have.
Cars use and lose oil quietly. A small leak or a bit of burning between changes is normal on many engines, which is exactly why an occasional look at the level matters more than waiting for a warning light.
The dipstick is your window in. It has two marks — a low and a full — and the oil should sit between them. Where the stick lives and how your engine wants to be checked are in the owner's manual; some newer cars use an electronic gauge instead.
Read the dipstick
Check on level ground, engine off
Park on the flat with the engine off and cool, following your manual — a few minutes after shutting off lets the oil settle so the reading is true.
- Level ground, engine off and cooled
- Some cars want it warm — your manual decides
Pull, wipe, dip, read
Pull the dipstick out, wipe it clean, push it fully back in, then pull it again and look at the film of oil. It should sit between the low and full marks.
Top up a little at a time
If it reads low, add the oil type your manual specifies in small amounts, rechecking as you go — overfilling is its own problem. If it drops fast or looks milky, see a mechanic.
An engine can't tell you it's thirsty until it's too late. The dipstick can, any time you ask.
