TundraGeneral discussion forum for the 2007 and later Toyota Tundra.
This is a discussion thread titled "Somebody PLEASE explain.........", within the Tundra forum, part of the Truck Forums category.
Checked the owner's manual called the dealerships etc.... the 5.7 holds 7.4 quarts of oil. I'm cool with that but why does it read over the full mark after it sets for 10 or more minutes? I could understand if it was the 4.0 Tacoma that had the oil filter on top of the motor but everything is down low on the 5.7's. I'm hoping anybody hopefully everybody can give a answer that makes sense........ Please explain......

Maybe it's really over-filled? I've had 4 dealer oil changes and 2 independent shop oil changes, have yet to use any oil between 5K interval changes, and have never experienced the symptom you describe.

Rear Susp: ProComp ES3000 #326510 (2.25" taller than stock), 1.25" blocks plus PRG mini-pack (http://www.tundrasolutions.com/forum...and-new-truck/) gives 2.25" total lift, parking brake cable bracket spacers, wheel well height 43."
Front diff and rear ds drop; trailer hitch electrical harness tucked up above bumper.
After 20K miles swapped 305/65/18 BFG AT for 285/75/18 Toyo AT, still on stock 18x8x60 offset TRD wheels, about 1/8" clearance to sway bar. Like the extra height but miss the width. Next time either 305/70/18 or 35x12.50/18.
Added 5th 285/75/18 Toyo AT as spare. Foam pad above spare to help with bed bounce.
Bed Bounce: Stiffer E-tires are worse than stock P-metric; biggest improvement from PRG mini-pack, slight improvement from shocks and foam pad above spare. Still a stiff ride but tolerable now.
Best things about this truck: 5.7 and transmission, interior size and comfort, very quiet at high speed.
Worst things about this truck: bed bounce, no VSC in 4wd, mileage sucks above 70.
Did you run the engine, it takes almost a quart to fill the filter, but the engine needs to run to pump the oil into the filter first.
I did my own oil, toped up the oil to the middle of the operating range on the dip stick, started the truck let in trun for a 20 seconds. Checked the dip stick, could barely see the oil level. That filter holds a lot of oil.
I only did this becuase I was using 4 liter M1 jugs and didnt want to over fill it my first time. It does take the perscribed amount.
I put seven liters in, leaves it just over the full mark. I found the rate at which the dipstick level rises is not very linear as you add oil. I wanted to get the level between the empty and full marks, so I added 6 liters and most of the seventh. It was in the middle of the range but towards the low side. Then I added the little left in the seventh liter and it shot just above the full mark.

It's a big engine and the top end has a lot of parts to lubricate, so there is a lot of oil there....mine has always done the same thing. Didn't have that happen with my 4 banger Honda.

That's about right. 7 liters = 7.4 quarts.

OOPS.. I did an oil change today and put 7.4L (7.8qts).. it read a little over full.. is this a problem? Secondly (not intending to go off subject) but i use Kofran Racing Synthetic oil if anyone's heard of it.. anyways its SJ-10W60! Comments??

No, no problem at all. I put in 8 qts every OCI and it's just above the full mark.
After the truck has been sitting for 10 minutes like you say, you must pull the dipstick, wipe it off, reinsert and then get an accurate reading. You should do this when checking the level while the engine is cold as well.

Right, this has come up a few times. The 5.7's retain excess oil in the dipstick tube, even overnite. Like "Only" says, pull the stick, the oil in the tube drains down, wipe the stick, recheck and you'll get an accurate reading.
You never get all of the oil out of the engine. There is always some hung up in the rocker valley of the heads. I would just put seven quarts of oil in after the change, run the engine to fill the oil filter and check it later and add what is necessary.

It has nothing to do with oil being retained in the dip stick tube. It has everything to do with surface tension of the oil. With the dip stick in the tube, there is a pile of surface area for the oil to come into contact. The synthetic and synthetic oil blends have a significantly higher surface tension than the older dino oils. The dip stick tube arrangement creates the perfect environment for capillary creap, a biproduct of surface tension and surface area. You can read all about this on BITOG.
I have the same "problem" in my 'vette, my wife's Maxima, and my older 4Runner after I switched to a synthetic blend. It's totally expected.
Somebody PLEASE explain.........
