Dipstick, dipstick...who's got the dipstick?
Dipsticks are used to check the levels in various underhood components. Fluid levels transmissions generally are checked with the engine at normal operating temperature, and running, BUT, some vehicles such as Honda, are checked with the engine off...consult your owner's manual or ask your service technician. Manual transmission and differential levels should be left up to the service technician to check. They are checked with a fill plug on their sides, and need to be up in the air to do it.

What do the marks mean?
Ok, you now look at the dipstick and see some marks on it. There is usually an F (full) and an L (low) on the engine's dipstick. The amount of fluid needed to raise the oil from the L to the F marks is generally 1 quart. Add 1/2 quart to the engine and recheck it to be sure. If it's now halfway between, then you know it still needs an additional 1/2 quart. It's always better to be safe than to overfill it.
