Oil light came on today.
Wife took car took a shop to add some oil.

he added 4 qts.

We called Nissan...Car only takes 3.6 qts

Having 2 or so too many qts in the motor is how bad?

car is scheduled for an oil and filter change first thing in the morning, anyway.

you didnt check the oil trekk?

the guy assumed it was empty when you brought it to him??? and added 4 qts?

I wouldn't think it would be that big of a deal.

.4 quarts overfill

Oh, I re-read the post. So why not drain some out.

Overfilling a modern engine can, and will, eat up the converter, the MAF, the O2 sensor, and various and sundry other bits. I wouldn't drive it around the block if it had more than .25 qt. over the mark. The Cap'n

Overfill is not reccomended, as Krusty points out. However, prudent engineering allows a 25% ( 100% in mission critical, 200 % in life critical applications ) redundancy. So, a quart I would remove as soon as possible but not sweat too much. Anything more than that I would not run the engine.

Thanks for the tips...I went out and hammered the thing on the back roads and it through a rod.

I drained off about 2 quarts...all's well.

When my wife called me earlier with the oil light, I met her and checked the oil.

My friend with the auto shop was just around the corner so I sent her there alone.
Apparently, reading a dipstick is one of the more challenging procedures.

When she got home after about five miles of driving she told me about the four quarts.

I have lost all confidence in my mechanic of 15 years.


Hopefully no harm done.

Yikes, through what means does this happen? I ask because I recently fixed a leaking valve cover gasket on my bro in-law's 99 buick century (3.1 V6.. terrible engine to work on, avoid it like the plague). Because of the bad gasket, it had about 8 quarts of oil/coolant sludge in it, and he had been driving it for a few days. I changed the gasket and drained it and put in new oil and filter, and new plugs while I was in there. Should I have replaced more things? (it seems to run fine now, with no check engine light)

My new Nissan Frontier V-6 calls for 5.5 quarts, so I carefully poured in a half of the sixth quart. I wondered if I should have just dumped in the whole quart.

I had bought a case of 12 quarts, now I'm left with 6.5 quarts.


With the 914, I always use 4 quarts although the manual says 3.5 quarts.
