Default Dipstick Question

Alright, I noticed when i check the oil dipstick that on the side that has the two letters for full (F) and low (or whatever the other letter is), it reads below the F, but on the other side of the dipstick it reads up to the circle cutout above the F. Why would that be, and where should the oil level be?

Read your Manuel. Below full and above low. Just concentrate on the F & L

mine does the same thing I fugred well as long as one is above and one is below I will say the middle is where its at. Has to be something with the way the dipstick slides into the oil pan is all I can think of.

always measure the oil level by the lowest one, good rule of thumb is start ur car, then let it sit for 5 min and check again, the lowest mark on teh dipstick is the one you should be worried about.

It's the angle the dipstick slides into the oil. You can see this angle if you look at where the dipstick enters the side of the pan.

Just dont overfill as that risks putting oil into the inlet which will coat your IC (wont cool well), poss damage some sensors(at your expense), and can cause det which will make you lose boost/power.

Even tho it makes you/me feel better to see the oil at the full mark, I like to run it closer to the 50%-75% zone. Less chance of windage/blow-by during aggressive driving and you still have 90% of the required oil in the motor.

Note, 1/2 mark on the dipstick doesnt mean you are half empty. It just means that you are about 1/2 qt below full. You will still have almost 4 1/2 qts in there.
