Oil Capacity 4.0 4wd?

What are you talking about !
Don't tell people that ...

Any engine's oil level is NOT read while it is still all up in the galleys (unless it is a very large stationary engine meant to be read through a site slass while running)...

Sure, if the engine is hot, the oil won't take long to run back down to the pan but many new owners don't realize that if they just ran the engine for a few minutes in the middle of a cold winter that checking it right after shutting it off will give an inaccurate reading resulting in them overfilling the engine.

I check my oil after the vehicle sits overnight, before ever starting it. After changing the oil and filter, I start it and wait at least 10 minutes for the cold oil to drain back into the pan.

1 - There is a reason the owners manual says to wait a few minutes after shutting off the engine before checking the oil ...
2 - The 1GR's dipstick has a difference of 1.5 liters between the add and the full marks. Just add 5 liters with a filter change then adjust after reading the dipstick properly.

You have your opinion, I have mine.. I'll stick with mine..

 

Not to chastise but let me reiterate what Toyota says in the manual.

 

Race cars with external oil coolers would obviously be somewhat different from a run-of-the-mill production vehicle.

 

i fill mine with 6 quarts of oil. i off road a bit and my junk is always at odd/extreme angles. i figure half a quart more will help to keep the oil pickup from starvation. just shy of 60k and no signs of leaks anywhere on the motor from having an extra half quart of oil.




same applies for the MonkeyCrawler...

 

Just remember. it's called an owners manual for a reason.

The procedures are to allow someone without the proper training or knowledge to perform certain tasks. The procedures are generic.
We can debate till the cows come home on how long to wait and how much to fill. If done by the owners manual it will give you an acceptable result.
Will it be perfect. In some peoples eye's yes. In some no.

Waiting 10 min or 30 min or 30 seconds is up to you.
Draining oil for 12 hours , 30 min, or 2 min is up to you.

Being an inch over is stupid and disrespectful and with either procedure the person uses, has way to much in it. Fired a guy 2 months ago because of this.

What it comes down to is everyone had there own way of doing their "OIL CHANGE"

Stopping at gas stations and checking oil is NOT Very Inaccurate.
Waiting OVERNIGHT is VERY INACCURATE according to the procedure.

Saying VERY INACCURATE puts up red lights and makes people panic.

If your full overnight your fine. If your full at a station your fine. It's going to be between the dots.

 

I changed my oil and used 5.5 qts. It was the perfect amount. I check my oil level exactly like the owners manual instructs, a few minutes after shuttiing off engine. I dont check it without running it because i follow the manual. I think checking the oil while fillig the gas tank at the station is a perfect and correct time to do it.

 

This is what I was shooting for...but being that I took it upon myself to have another dealer take care of the issue, I didn't have the pudding to prove my point. We'll see if any damage comes as a result from this bs

 

I really wouldn't be overly concerned about damage. You just got the truck and found it. No mention of anything funny going on. no smoke or running rough. I've seen trucks come in from a quick lube smoking like a freight train with over double the right amount. I guess it was fill it till you see it in the filler neck. The truck left with no smoke and running correctly and no lights on. I still see it once in a while and he said he would be back for us to check it if something he thought was related to the event. This happened few years ago.
By all means make sure the original dealer knows what happened and that it's documented along with the other dealer invoice and paperwork. Save all your paperwork too.

Enjoy your new toy. Nothing like getting a new set of wheels.

 

Hi all.

Hi Mike.

I agree that people will check their oil level however they want.
I don't agree that checking the oil level first thing in the AM, before starting the engine is inaccurate.

Here is an excerpt from my owners manual.

With the engine at operating temperature and turned off, check the oil
level on the dipstick.​

Checking the engine oil

​

​

Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain​

back into the bottom of the engine.

"With the engine at operating temperature" and "After warming up the engine" means the engine is hot. They still want you to wait "more than 5 minutes".

The reason for this is because the oil is to be checked after it has drained down into the oil pan. With the engine hot it still takes some time for it to drain back into the pan so it can be checked properly. Checking after it sits o/n will give you the same reading on the stick as the owners manual procedure because the oil is still drained into the pan. The reading will be the same - try it.



On another note - checking the oil level improperly or filling it overfull is almost as harmful as running the engine low. It results in foamy oil reaching the plain bearings because of the crankshaft running through the oil in the pan ( the outer parts of the crank are moving at well over 100 mph when the engine is revving high). Although this is not as bad as no oil, it still results in journal to bearing contact under load and therefore takes some life out of them. I understand that if the truck is run at extreme angles there is the possibility of the pickup sucking air but surely there is a better option - (a dry sump setup ?)

Mike, it would be an interesting exercise to tear down an engine that had its oil checked right after shutting it off for its whole life compared to one that was checked properly. I would bet there would be some big differences in the bearing material. Do I think your way will blow up an engine - no, but I don't agree it is the proper way to check an engine oil level.



On yet another note - I don't agree the owners manual procedures are "generic".
1 - Toyota wants things done a certain way and they outline it so people that aren't as savvy as you (and I, and many on this forum) will do things properly.
2 - The repair manual reinforces the same procedures
3 - When it comes to oil level checks, all of the makes and models have the same procedure that is outlined in our Tacoma manuals. For good reason - an engines oil level is checked after it has finished draining into the oil pan.

Mike, I have also raced for many years (not any more unfortunately). I wonder if some plumbing changes to your oil coolers or even just a check valve would allow you to let the oil drain into the pan in your race engine so it can be checked properly. I question whether you are running it overfull that is taking life out of your bearings and possibly just as importantly, is robbing you of horsepower (for the reasons I stated above).

As I stated above, people have their own way of doing things, but there is only one proper way. I'm not trying to tell you what to do, as a long time mechanic you must know your shit. I'm just trying to state the proper way for any owners that aren't as interested in the mechanics of engines as we (and many here) are.

Peace.

Cheers
Ray.

More likely it was drain the ATF and install 5 quarts of oil.

Happened on this forum more than once.

 

I don't see any budging here.

 

The important part you aren’t paying attention to in the owners manual is that the engine should be warmed up before you wait a few minutes to check the oil. Checking it first thing in the morning means checking a cold engine.

It’s not just about letting the oil drain to the pan. It’s also about the oil temp. Cold oil will read lower on the dip stick.

Is it a huge difference? Not at all. Plus/minus 1/2” from the full mark won’t make or break the engine. Am I a Toyota technician? Not at all. I’m jut a guy that’s been changing his own oil for a long time.

 

5 quarts in my 4.0 been doing it since the first change since 5.5 puts it way over full.

 

If Toyota says 5.5 quarts with a filter change, why would you deviate? Do you have your own million dollar testing facility and data to argue otherwise?

 

5.5 quarts synthetic & fresh filter.........

good for 6K miles

 

Granted this thread was started 6 years ago, ha! I do 5qts every change. Brings me to full on the stick.

 

5.5 qts of full synthetic. 7k on the oil, still honey color and clean. I'll change at 10k and check if it could go longer.

 

What is this magical oil you speak of? How is it still honey colored after 7k? That alone would make me nervous as its not possible.

 

Mobil 1 Extended Performance. Rated for 15k miles.


They also make some rated for 20k or 1 year.
