Post subject:  Which level on the dipstick looks correct?

I just recently changed my oil and switched over to Mobil 1 5w-40 TDT oil and I put 6.4 (slightly off...I put in 6qts plus 12oz) quarts in. I let it set over night to observe the fill level on the dipstick. This is where it was at:

The level was high enough to just cover the "M" on "Min". That was on Wednesday. I re-checked the level this past Saturday and this was where it was at:
Image
The level had come down a tad so the the "M" in "Min" was visible. This was once, once again, after sitting over night in the same spot. I know the dipsticks are incorrect but I would have thought the first reading would have been correct after putting in a meaured 6.4 qts. Which level looks more accurate? I am trying to get the correct fill level down so if I have to add any oil between changes I get it to the optimum fill level without over filling.

Also.....how much, if any, should I expect to have to add between changes on a 6,000 miles change interval?

Thanks, Jim

I use the WIX 51515 filter which is oversized. 7 qts puts me in the middle of the range on the dipstick. I end up just above the minimum after 6250 miles without adding any oil.

After the initial oil change did you run the engine to fill the filter? The filter will hold quite a bit of oil which may explain your readings. Always run the engine for 30 seconds or so after the fill then let it sit overnight on a level surface.

The filter I use is the Purolater Pure One filter that I believe is a standard size. After filling the oil, I backed the jeep out of the driveway of the garage and over to another spot that is more level as the driveway is sloped a bit. I wuld think starting the engine and driving it 20-30 yards would have filled the filter. I'll keep and eye on the level.

Yes it only takes a few seconds to fill the filter so you should be fine. I usually twist the dip stick around 360* before pulling it to ensure full coverage for the reading. I put in around 6.5 Liters in mine with the larger WIX filter.

For those US folks who are conversion challenged - 6.5 liters is a hair shy of 6.9qts which is close enough to the recommended 7qts for the oversize filter.

For me consumption is seasonal. I need to add about a quart midway in the winter. In the other 3 seasons it goes the full 6K without a topup but it will be on the min mark at that point.
