Typical capacities by engine
Engine Typical Capacity
Always use the exact capacity from your owner’s manual, since published figures usually already include the amount held by a new oil filter. Add oil gradually and confirm the level on the dipstick after the engine has run and settled; it is easier to add more than to remove an overfill. One US quart is about 0.95 liters.

How Much Oil to Buy

The real question at an oil change is not just the capacity, it is how many bottles to grab off the shelf. This tool takes your engine capacity, converts between quarts and liters, and tells you how many containers to buy and how much you will have left over for top-offs between changes.

Does the Filter Change the Number?

A new oil filter holds a few tenths of a quart of extra oil. Most manufacturers publish their capacity for a change that includes a new filter, so the figure in your manual already accounts for it. If you are only draining without changing the filter, you may need slightly less.

Topping Off Between Changes

If your level has dropped, you rarely need a full change worth of oil. The distance between the low and full dipstick marks is roughly one quart on most engines, so a reading at the low mark means about a quart will bring it back up. Add in small amounts and recheck.

Frequently Asked Questions

Where do I find my exact capacity?

Your owner’s manual lists it, usually in the maintenance or capacities section. The reference table here gives only rough ranges by engine type.

Is it bad to overfill?

Yes. Overfilling can aerate the oil and stress seals. Add gradually and stop at the full mark rather than dumping in a full jug.

Quarts or liters?

One US quart is about 0.95 liters. Buy whichever your local shops stock; the tool shows both so you can match bottle labels.
