How to Check Oil Level in 6 Steps
Written by Muneeb Rana · Last updated 21 October 2026
Quick answer: To check oil level, park on level ground with the engine off for a few minutes, pull the dipstick, wipe it, reinsert it fully, then pull it out again. The oil should sit between the MIN and MAX marks. If it's near or below MIN, top up a little at a time with the grade in your manual.
TL;DR
- Level ground, engine off, wait a few minutes.
- Wipe, reinsert, read between MIN and MAX.
- Top up in small amounts with the right grade.
Knowing how to check oil level takes two minutes and is one of the best habits for engine life. Here's how to read the dipstick, what the colour means and what to do if it's low.
Six steps
- Park on level ground and switch off the engine. Wait a few minutes (or follow your manual; some say check warm).
- Open the hood and find the dipstick, usually with a yellow or orange handle.
- Pull it out and wipe it clean.
- Push it fully back in.
- Pull it out again and read where the oil film ends, between the two marks.
- Push it back in fully.
Some newer cars have no dipstick and show oil level on the dashboard; see your manual.
What the marks and colour mean
Between the marks is fine; the gap between MIN and MAX is often about one quart or litre. Amber to brown and translucent is normal. Very dark, gritty or sludgy oil suggests it's due (signs you need an oil change). Milky or foamy oil can mean coolant contamination; get it checked. AAA's fluids guide covers other fluids too.
If the level is low
Add a small amount of the grade in your manual through the filler cap (not the dipstick tube unless specified), wait a minute and recheck. Don't overfill. If you're adding oil often, look for leaks or oil burning. A red oil pressure light means stop driving.
How often to check
Every few fill-ups or at least monthly, and before long trips. Add it to your car maintenance checklist and your car maintenance for beginners routine, and log changes so you know how often to change oil. CarO can remind you when the next change is due.

FAQ
Should I check oil hot or cold?
Most manuals say check with the engine off after a few minutes on level ground. Some specify warm. Follow your manual.
How do I read an oil dipstick?
The oil film should end between the MIN and MAX marks. Wipe and reinsert the dipstick once before reading.
What colour should engine oil be?
Amber to brown and translucent when fresh-ish. Very dark and gritty oil is due for a change; milky oil needs inspection.
How much oil should I add if it's low?
Add a little at a time, perhaps a quarter of the gap, recheck, and stop at the MAX mark.
Is it bad to overfill oil?
Yes. Too much oil can foam and damage seals. If overfilled, have some drained.
