and what happends if the oil's over filled? &lt;---From what I read in one of the tech note somewhere, it may cause the oil pump to fail prematurely. Keep in mind though, this is if you drive your car this way for a long perious of time.

So it was a smidge down and you added 2 quarts? Why? Anyways, that's water under the bridge I suppose...

What would happen? You'd get a synthetic blend...makes sense right? I hope you at least used the same manufacterers.

Too much oil can blow seals and or cause foaming of the oil= not good. Drain a little out, takes all of 5 minutes

While your question was answered, here's how to avoid this problem next time.

As you know, there are two dots (holes, actually) on the dipstick. (Some brands of cars use notches instead of holes.) The distance between those two holes is exactly one quart. Therefore, the next time, if you see that the oil level is halfway between the two holes, that means you can add HALF a quart and it should be at the level of the top hole, not overfilled.

Many brands of oil these days come in plastic bottles which have a thin stripe down the side, and the stripe is slightly translucent, so you can see the level of the oil inside the container. This will help you know when you have poured half a quart out of the bottle.

How long did you wait after shutting the engine down and before you check the oil?

I think that's what the owner's manual tells you to do, too...

Just an FYI, all Hondas are not this way. I found out the hard way on a D16a6. Had to end up draining some back out.

I thought all Hondas (heck, all cars) are this way. How does it work on a D16A6? Heck, what is a D16A6?

Yea I am 95% sure that all honda's are this way.

Hey looking at the picture above, my oil exceeds the top circle by about a half of a quart. Does this mean I am a halfway over? IF so, is this that bad?

A D16a6 is a Civic Ex engine I believe... SOHC VTEC... and i do believe that on my buddies D16a6, his dipstick reads a quart between the two dots also. Not 100% sure, but when its low he puts in about the same 1/2 a quart to get it between the two dots.

Reason why I ask is because I am not sure if it is supposed to be in between the dots or if its alright beeing over the two dots a half or full qt. over?

D16a6 = oem Honda motor in a 88-91 CRX Si/Civic Si.

The oil level was just below the first dot. I threw a quart in the motor and it ended up well above the top dot. Well above.

Can anyone verify this to be accurate, b/c my car is too low to change the oil and since I am at college I dont have a nice garge to do it in. So I let the shop I go to do the oil change. I do it right before 2,000 miles and supply them with a new honda filter w/washer every time. I am always about a half to whole qt. above the second dot and never had issues with my car.

Anyone?

mixing the two oils is not bad it just causes the synth. oil to lose all / most of its properties
ie you just waisted your money on buying expensive oil and having the caricteristics of cheap oil........... good job
