Overfilled Oil

Best advice right here. Can't hurt to to have the correct amount of oil, and it's not too tough to let a bit out.

Doc's right, as long as it's no more than 1/2" over full your OK. My 1994 Z34 has the 3.4 liter motor that takes a small oil filter and the manual states 5-1/2 qts. with a filter change. I've put 6 qts. in it ever time I've changed the oil. The motor has 126,000 fairly hard miles on it and runs like new still.

I originally asked the question because I did not want to waste fresh oil for no good reason....and in my case, it looks like there isn't one. I looked under the hood and DID notice some oil dripping down the skid plate....like you said, it must have gotten spilt when they changed the filter. I wiped up the excess and hopefully that will be the end of the little oil drips! Thanks....very good and sensible post (just what I was looking for)!

It's fine. Your truck takes about 4.75 qts and they likely just added 5 qts. 1/2" over "full" ain't going to hurt anything.

Doc =3D=3D=3D=3D =3D=3D=3D=3D "Lawrence Glickman" suggested in message:

Dump the extra, do it now. And don't go back to the jerk you paid to screw up your ride.

Lg =3D=3D=3D=3D=3D =3D=3D=3D=3D=3D snipped-for-privacy@spiderman.com (Spiderman) scratched his head and asked:

Hmmm....I wonder who's right? The Doc (leave it alone) or Lg (dump the oil)?

I am going to side with Doc on this, 1/2" over the full mark wont hurt a thing, =3D=3D=3D=3D=3D =3D=3D=3D=3D=3D snipped-for-privacy@business.net (Bret=A0Chase) cast his ballot with:

leave it alone.... a 1/2" high on the dipstick is negligible.... don't worry about it unless you're a couple of inches above the full mark.

GUESTIMATE how

diagnosis, Doc?

1/2" won't hurt you at all. That equates to about 1/2 quart. I always put in 5 quarts with filter change in the wifes 4.3. Look at it this way. The sump holds 3 quarts without touching the crank (the crank is actually 1" or so in the oil before the pump starts working). Now when you actually start the engine the oil pump does it's job. On the 4X4 with the small filter the filter holds 1/2 quart, the lines and cooler hold another 1/2 quart. Now add the oil passages in the engine up and that takes another 1.5 quarts. What does that leave in the sump? Correct , 2 quarts. If it takes 3 quarts to get to the crank you still have 1 quart to play with.

Now if you go nuts and dump 6-7 quarts in you will have problems.

Doc is right. The idea that your crank will have to spin through the extra 1/2 quart is just wrong. Same for any idea about it causing foaming and thus bearing failure.

When we used to rebuild engines we put an extra quart in to be sure the new motor had plenty. A half quart overfill won't hurt anything.

Related funny story... I asked my 16 YO son to go check the oil in his mother's car, before we went on a driving lesson. He went out and came back in about 15 minutes later, saying that it was low and he added oil to it. He said it was 3 quarts low. I asked him how he knew that. His response sent chills down my spine. "Well there were 3 holes showing on the dipstick, so I added 3 quarts. I also started it so it would be reeady to drive, lets go". Well it was running, but it sure sounded funny. I shut it down, and checked the oil, it was, as I expected, about

I drained seven quarts from one once and it had not been causing any problems. The person had it changed at one of the quick change places. I just noticed it was way up the stick and started looking for any problems and so measured the drainage. It had been in there for some time too.

If it shows up in the oil pressure it is too late....

Well to the unknowing that was a good guess on his part. Three holes should mean three quarts. At lest he thinks for him self.

Exactly! And think about this guys, the accuracy that the dip stick tube is press into the block is probably +/- 0.035" and the tolerance on the dip stick pressed into the handle is probably about the same. So right off the bat a Friday or Monday car is 0.070" off location to begin with. Grant it that's not that much but it just shows that this method of fluid checking isn't that accurate or does it need to be. After all if you drive up hill, down hill, or around corners the level changes all the time anyway.

Plus, some 'flat' surfaces where people check the dipstick are not entirely flat so the reading can be slightly off.

I've also intentionally overfilled (slightly) cars that use/burn/leak oil in the past. It reduces the much greater risk of damage from having too little oil, and I never saw any problems from it.

Personally, I'd just climb underneath and let some of the extra oil out. But, if you have an aversion to getting under there and making a mess, there may be a simpler solution....

To change the oil in my inboard-outboard boat, I pump it out through the dipstick. That's the way it's done in boats. So, you could drop by your local boating store and pick up a pump for $20 or less. Pump the extra half-quart out and save it for later. No mess, and you'll have a handly little pump left over that you can use for something else in the future. Personally, I've never done this on an automobile, so take this advice with a grain of salt.... Just make sure the tubing used on the pump will fit into your dipstick tube.
