Well my 6 months rolled around so figured it was time to finally change my oil. Damn it was so nice to be able to remove the drain plug without having to jack up the vehicle. The filter was a little stubborn but I used the old type of filter wrench and removed it with hardly any effort. Drained everything and re-torqued the drain plug after installing a new plug gasket to 28 ft lbs, yeah I know it recommends 30 but I'm using a cheaper torque wrench and always worry about overtightening stuff. I ended up putting in 5 quarts even though it doesn't come all the way up to the upper dot on the dipstick it looks as though 5.5 quarts would be way to much. Just curious but how much oil did everyone else on here end up using for the 4.0?

Do you have a Prerunner or a 4x4?
It's a common misconception that both take the same amount of oil. The 4x4 takes 5.5 quarts, the Prerunner takes 4.8.
The dipstick is useless. Your better off having a little more than a little less. The best thing to do is figure out how much oil came out. Make sure your truck is level when you drain the oil. And make sure the oil is warm to hot. You might have 0.2 or 0.3 quarts of old oil still in the pan.
Still, I'd add closer to 5.5 than 5 if your engine calls for that. A few extra tenths of oil won't do any harm. A few tenths to half a quart low on oil is comparably worse. Not detrimental but not positive just the same.

Well I have the Prerunner so I guess I'm good to go since I added 5 quarts. The truck was level and the oil was warm so I did that right.

I have to disagree on two points-
The dipstick is not useless, it is the only means that you should use to determine if you have proper oil fill. The volume calculation for the sump is an approximation, provided so that you know how much oil you've got to have on hand. The dipstick determines the oil level. The high polish of our Taco dipsticks can benefit from running some sandpaper across the stick in the gaging area to give the oil something to "grip" and give you a clearer reading than the spotty one you get on a new stick.
Always fill to a level between the lines or "dots". More is NOT better. Lower than "perfectly full" only causes a problem if it is so low that you decrease the volume of oil that can provide cooling by dumping heat to the sidewalls of the sump, or that you drop so low that the oil pickup sucks air. Overfilling can lead to foaming and other issues. Never overfill. I always target the "full line", but not over. If you're gonna be a 1/2 qt off, be lower than absolutely full by 1/2 qt, not over.

I was talking about a few tenths. You're talking about a quart... or more. There is nothing wrong with being at the suggested amount of oil. Put in 5.5 quarts every oil change in the 4x4.
An engine will not foam from 0.2 quarts of oil. I don't even know what "other issues" is supposed to mean. Maybe blowing out the seals from too much pressure? Again, I never said to overfill by anything more than a few tenths to maybe half a quart.
And I greatly disagree that you can run your oil half a quart low. Why bother buying that extra bottle of oil if I can run 5 quarts in my 5.5 quart sump? Low oil will give you low oil pressure. Not to mention sharp turning causing oil starvation.
I know about the dipstick. I'm one of the first people to have sanded it. Thanks for regurgitating my advice for me.
I know you think you're an expert in this field but I'll take advice from founding members of BITOG over you. Thanks again.

Are you saying that running 1/2 quart low or 1/2 quart high will change your oil pressure?
I think the extra oil for the 4x4 is to protect it while you are actually off road. For steep angles, etc. to make sure that the motor isn't starved of oil. I know in the Z06 they recommend an extra quart when road racing because of the oil that is sloshed around in the pan and windage tray area.

Boone- I don't know what it was that I typed that particularly irritated you, unless it was that I just didn't agree with you. I apologize for anything offensive that I wrote, but not for disagreeing. The point of my post, as should be the case in all of them, was to provide the other point of view -particularly for the person who originally posted.
I shouldn't think that would offend you, so if I somehow wrote my point of view in an inflamatory way, my apologies. As for the sandpaper, feel free to claim credit for it, but you will have to excuse me if I don't search to see if what I'm about suggest in a post might have been suggested before by someone (including myself). [fwiw, I sanded my own in Feb 2005, and mentioned it on Edmunds before I came to TN.]
I am not an "expert" in lubrication. Tribology is not my area of specialty. Yes, I do have a great deal more experience and academic background in lubrication, filtration, and mechanical component design and failure analysis than the average vehicle owner, but as an engineer, I am not an expert. I offer my comments based on my own "backyard experience" for 35 yrs and 26 yrs as a mechanical engineer engaged in design and analysis. But, in the engineering profession, I probably have only slightly better than average knowledge of the subject.
As for BITOG, it's certainly a great source of info. I haven't read every page of the site, but haven't come across anything to date that I question.
I do feel strongly that one shouldn't ignore the recommendations of the manufacturer, just because "somebody's buddy said", or the "service writer at the dealership said", or whatever, without some pretty significant added support for that alleged expertise. Some guy whose 15yrs experience consists of writing "oil and filter change" on a clipboard, then handing it to the technician who actually does it, is not in the same league as the guys who design, build, and run 1000s of hrs of tests on the equipment.
Again, if anything I wrote indicated an intent to belittle you, I apologize.
I would appreciate it if you would extend the same courtesy.
