Is 7 quarts of Mobil1 too much for Q45?

[moshmoshi]

I put in 6 and seem a bit on the low side,and I don't want to put 1/2 moreand have the rest hanging around.

What year is your car?

Yes, please complete your profile so we can help you.

7 qts. is too vany for any VK or VH seres engine. Is your drain plug installed and filter on tight?

7 quarts is perfect for the 90-96 Q45...... 6 go in the engine and 1 goes in the trunk to be used throughout the oil change interval for top offs.

6 quarts on the nose should bring level perfectly up to proper level on the dipstick WHEN PARKED ON PERFECTLY LEVEL GROUND and after allowing at least 1/2 hour after shutdown before checking.

My dipstick level continues to climb and takes over 1 hour after shutdown to reach its maximum level=that ester based redline likes to cling to the metal engine internals and takes its time returning to pan

Sorry, 95 Q45, 122xxx, 5.9 quarts of Mobil 1 put in last Saturday. Oil leveljust a little on the low side ( if being right in the middle fo dip stick is ideal)And I checked the dip stick from this morning, car has not been started since last night.

Highly unusual for the Q to need more than 6.000000000 quarts to bring it up to top of hash marks on dipstick.....if you are checking on perfectly level ground after plenty of time after shutdown to allow oil to drain back into pan, then add a little at a time to bring level up to the top hash mark on stick-try adding about 1/4 qt and see where you are.

With drain and new filter, 6 qts exactly. When I do the envirolution crackcase flush, it will take 6.25 qts.

Yesss...but Q45s don't burn any oil. Make sure you are on perfectly level ground. If that doesn't work try starting the car up for about 15 seconds and then check. Mine said it was low then somehow after a quick on and off it was at the proper full level.

Including filter fill, just a tad under 7.

Maybe for that little metrosexual convertible, but too much for a G50

Same here.

***Correction: I use 6 liters not quarts.

No, its a bit under 7 quarts. You pour a little into the filter prior to installation, then the rest into the crankcase.

Oh snap! Sick burn.

Unfortunatly, manual stating 6&3/8 quarts was wrong, as has been discussed and proven here on this site over and over. 6.0000000000 quarts with new filter is the correct amount for the 90-96Q.

3 years ownership makes you a Q toddler in my book, as I have been an infiniti owner since 1994 having personally driven and maintained over 350,000 miles in my G and Q, and a Nissan product only owner since 1979!

Might want to update that site of yours, you listing of API SG & SH oil specs are embarassingly outdated, as the API current spec is SM.

And previous threads also point to -just under seven quarts-. I've owned a Sentra, Maxima, two G50 Qs, and in addition took care of a G20 and 240. We both know plenty.

7 is slightly on the high side but not enough to cause any adverse effects. Filter size when using non-oem can also contribute to oil capacity variance.

[Q45denver]

Depends on how long you let if drain. I've added 6 quarts and I've added 7 . Check your dipstick. I've owned Nissans since 1972.

I would have to say that Drew is correct!! i put oil in my 93 Q for the first time after installing rebuilt transmission and motor and mine took exactly 7 quarts. I couldnt get ahold of a OEM when i needed it so i bought one from NAPPA, NOT BY CHOICE! The nappa filter was twice the size of oemoil filter. Another thing that could affect oil level is the metal tube that oil dipstick goes in, if its bent or out of whack or turned a little it will effectthe oil level, or if you install dipstick pointing wrong direction!

When one buys an old q that has had 3,4,5++???? owners over the last 10-15 years....one has to wonder if they even have the correct dipstick for the engine? If it takes more than 6 quarts to fill, sure would look to be absolutly positive you have the proper dipstick, as there are many slightly different lengths that all appear similar
