Hi Guys,

I changed engine oil at the dealer on Nov 28. (It is about 13 days ago)
After the oil change, I feel some burn smell around the hood side.

This happen quite often after I come back home from the work. (About 25 mile driving, mostly freeway).

Today I felt again, so I checked engine oil level. What the $%$%.
The oil level was very high. It almost looks like they forgot to drain the old oil.

Look this pic I just took. You can see how much dealer over fill the oil.



I also took the paper towel to wipe out the oil from dip stick.
It look kind of dirty considering oil change was done only 13 days ago.
Can you guys can tell if this is dirty or not?


I will go back to dealer to drain out the oil.
I just worry about my car engine. What if engine got damaged? Should I ask dealer to check the engine for me?

What should I do? Any opinion?

It seems strange to me that a dealership would overfill a crankcase, but mistakes happen everywhere. Check your oil first thing in the morning when the engine is cold. If the level is still that high, then things are definitely not right.

I doubt that the old oil is still in the engine - even though your oil has started to change colour, it doesn't look dark enough to me to suggest it wasn't changed. I'm sure other members will offer more opinions. Engine oils contain detergents that will clean gunk and deposits from inside your engine. So changing colour is a sign that the new oil is doing a good job of cleaning.

You should have any excess oil drained as soon as possible. It's not as though your engine will implode tomorrow with the extra oil, but it's not something you should let slide.

That will not hurt anything,. That is most likely 6 quarts instead of the 5.5 it needs for a fill. I do the same thing with ours for almost 4 years now will no issues. My guess is the burning smell was them dripping the oil on the exhaust manifold. The oil looks new

ditto flyin's comments. Plus I trust you used the proper procedures to check the oil: Rav parked on a level surface and cold engine. Just checking.

If its a quart from the low mark to the high mark for filling, how can an assumption be made that its only .5 quarts overfilled?

Not knowing the exact design of the dipstick tube, I would say by simple measurement from "low dot to high dot" and the extrapoloation from the high dot to the edge of the liquid line are the same.

However if it wasnt cold and on a level surface, all bets are off.

Nope - you are assuming that the shape of the bottom of the engine block and the shape of the oil pan is constant as it goes up. The only way to know this _for sure_ is to fill to the Full mark, then add another quart and see where the level is on the stick. You can't extrapolate by the existing marks.

OP: I suspect the oil level is slightly high - just get the dealer to lower it to the Full mark. You are right to be concerned, but it isn't a big deal. Your motor is fine, but it appears that the tech screwed up.

Should he also check the filter? Sometimes the oil level appears high because they put on the wrong sized filter i.e. too small. That would leave more oil than normal in the engine itself. Just a thought.

That does look like new oil to me.

Thank you guys for posting.

Just for the verification, I did check the oil level when engine is cool and the car is parked on level surface.


It seems that my car will be fine. (I am still very concerned about this)
It is really surprise for me that only 0.5 quart can make this much high level on dipstick. (The dipstick did show oil level about more than half inch above the full level as you can see from the pic). It is written in invoice (work order ?) that they put 4 quart of oil though.

Anyway, I will contact dealer today and bring back the car tomorrow. I just wish my engine is fine. (Probably I will make big deal out of this to dealer. I am about to write to Toyota cooperation about this overfill issue. )

I will see what dealer will say. I will post again after the dealer visit. (Is it OK to post dealer name?)

Thanks guys.

Scoobs, it is very unlikely that the incorrect sized filter was used given the design of the V6 filter canister. I know what you mean as I use different sized filters on my Chevys. There are at least four different capacity filters out there for them.

It is important that the OP gets that oil level down sooner rather than later - it does matter.

Too much oil in the crankcase can result in bearing damage (if the crankshaft dips into the oil and froths it) and it can fool with the PCV valve. Those maximum levels on a dipstick aren't just to keep you from spending too much on oil or making a mess on your driveway - they are there to protect the engine.

That being said, this particular case doesn't look too serious, and the OP is handling the problem appropriately. But we shouldn't be giving people the impression that overfilling the crankcase is no big deal.

Update 1.

OK guys.

I just got off from the phone with dealer service writer.
He basically is saying bring the car down to him so that he can take a look.
He keep telling me JUST over half of inch over the full oil level will not hurt the engine at all.

So Toyota put oil stick and mark as full is for decoration??? Just over half inch is fine??? Toyota manual clearly say don't over fill the oil. It can cause engine damage.

I don't understand how he can work at Toyota dealer even don't know the basic.

Yeah right!. If your blood pressure is just high over the dangerous limit, it will not hurt your health at all. :evil:

Anyway, he gave me tomorrow 10:00AM appointment.
I will see what will happen. I will keep update. They can be dealership or stealership. Their choice!!

Some vehicles can handle overfilling with no problems. As a matter of fact, it is standard operating procedure for BMWs where you overfill the crankcase by one full quart if you are taking it to the racetrack. The sump is deep enough that the crankshaft won't froth the oil even overfilled by that much.

As to why the manufacturer would allow usable capacity over the "full" mark, it is usually to accommodate inaccurate filling, or because the size/shape of the sump benefits cooling or pooling of oil in some way. In any event, I wouldn't worry about it unless you pull the dipstick out and you see the oil is milky looking. That is a sign that air has been whipped into the oil and that you'll need to drain some out.

Thank you for your information.

I wonder if there is anything written/confirmed that RAV4 has such a usable capacity over the full mark. If you have such a source can you share with me?

There is another concern that I can smell burn from the car. It seems oil burn smell which I never had before.

If this is just your own opinion or just heard from somewhere, I am still worrying about my car engine.

Thanks.

overfilling the crankcase by 1/2 quart is no big deal. Which is what was shown on the dipstick. Don't overanaylze its not big deal..

All vehicles will have some excess capacity over the full mark. It's just a matter of how much.

The burned smell is unlikely to be from an oil overfill condition. You'd see bluish smoke from your tailpipe for one, and would probably throw a code for another. There also has to be some way for the oil to get into your cylinders to burn, and that won't have happened just because the oil got overfilled. More likely, some oil got on your exhaust manifold, downpipe, or catalytic converter, and that just takes a couple of weeks to burn off.

Again, if you see that your oil has a milky look (pull your dipstick right after driving it), you can assume that some rotating engine component is whipping the oil into a froth, and are then definitely overfilled. Otherwise, I personally wouldn't worry about it with the amount of overfilling that you showed on the dipstick.

If you did want to lower the oil level (I don't know if this would work - I'm just thinking out loud), I believe you could buy an oil filter and use the canister drain plug to let some oil out without removing the drain plug.

Hello Guys,

I just came back from the dealer.
They double checked oil level again over there with me.

They told me the oil is about half quart over filled which will not hurt engine at all.
And it is not even worth to drain out.
Yes, as some of forum member posted.

Anyway, they put this into my service record. (Something like "Customer state oil level is too high but checked it normal."). Fortunately it didn't affect my engine but half quart or whatever amount of overfill is overfill.

So I decided to bring my own oil according to owner manual. (5.4 quart with filter is in the manual - I will bring 6 quart and check the remain). I asked them if I can bring my own oil and they say "Yes".

I will bring Mobil 1 5W30 from Costco (6 bottle of 1 quart oil) from now on.

Anyway, thank you for guys posting opinions. I learned my lesson.
Great forum.

Thanks.

Ditto. I would be concerned if you went 5000 miles with it overfilled but, you didn't. If you can't let go you can send an oil sample off to get analyzed for around $30. Excess metal contamination will show up if it's there. Maybe you can convince the dealer to do it.

Maybe the idiot forgot to change the filter. Replacing with the "correct" amount of oil would explain the overfill and the color of the oil.
