Engine Oil Overfilled?

Register to hide this ad
Opinions may differ, but me personally I wouldn't be too worried about that little bit over...you have to factor in if you're checking it completely leveled, right after shutting off a running engine, etc.
 
I would rather it be that low than that high. Don't fret about it but drain some soon. Double check it cold and level.

Ditto. It's not going to hurt being a bit over. It just sitting in the bottom of a pan waiting to be pumped up and circulated through the engine. It won't leak out.
 
If it was mine.....I would drain out a quart ASAP. Rumored that overfill could cause tiny air bubbles. Air can't lubricate where oil is needed. Just saying.

That amout of overfilling won't cause foaming. Much more could when crank smashes into the oil though
 
Is it just me, or does the Oil Dipstick always seem to have excess oil on it (above the actual fill level) making the actual level hard to read? Seems like the long tube might be screwing with it? It's probably best to check it cold before any engine activity can stir up the oil...

:cool:

The manual says don't exceed the (2) fill line; is this in excess to the extent that it should be adjusted?

Step one, make sure of your measurement.

After that, you should at least be aware that the low-to-high span on the dipstick represents 1.8 quarts.

Probably won't hurt anything but if it were me, I'd drain some out.
 
Is a jack/jackstands necessary for changing the oil? I tried rolling myself underneath the vehicle but there wasn't enough room for moving about; I couldn't have undone a bolt or the like - there wasn't enough space.

Seems to me you've already answered your question. You could also try ramps. a pit, or some type of lifting arrangement.

If you are unnexperienced, I would highly suggest using ramps. They are pretty affordable at your auto store, you can probably get a set for 50-80$.

Using a jack and stands is a very risky way to get underneath your truck if you don't take the necessary precautions.

This is one of the benefits of having a lift - not having to use a jack or stands to change the oil and other basic stuff.
 
Take back to dealer and tell them it appears to be overfilled by 1 quart and let them document and deal with it. Oil looks dirty to me.

Would love to have this, but as far as I know, the rails of my garage doors would interfere with a lift pillars. So its ramps when I can, and jack when I have to remove the wheels. Still way better than when I had to do my maintenance in my dirt driveway at -20 deg.
 
Oil Over fill

Since Toyota and Lexus never require oil to the even quart level, they always put the last full quart in. Most Toyota's take around 6.6 quarts. They typically put in seven. My LS460AWD requires 9.5 quarts of oil. They always round it up to 10 quarts. I have had numerous models of both vehicles and I never concern myself about it. They are the ones who did it and it even states it on the invoice they give you. I figure with the length of time of the powertrain warranty if anything were to happen it would do it by then. I check my oil after each service to be sure they did not underfill. This happened to me once with a 98 4Runner. It was 2 quarts short. I reported this immediately to the service manager, who topped it off and fired the guy who did the work.

I wasn't clear - when I said "lift" I meant having a suspension lift - not a hydraulic lift. I haven't used a jack or jackstand since I put the lift on my truck unless I needed to remove a tire. :) Sorry for the confusion
 
WAY overfilled

So I have the extreme case in a 2011 with 36,000 miles. Turns out the dealer tech either didn't drain original oil or he double filled with new....noticed a slight flutter at idle some time later but didn't tag that to the oil change - thinking it must be some sensor or whatnot so...drove around for a couple of weeks. Stopped in my neighborhood shop and asked for diagnostic, of course they found nothing, mechanic pulled dipstick and made the discovery...drained all out, estimated it was double, refilled with correct amount...flutter went away....I've asked dealer for diagnostic and inspection and of course will be following up with letter to them and Toyota USA in case something shows up later. What type of diagnostics should I ask for? Had someone mention catalytic converter.
 
Oil Overfill

Indeed it is possible it is overfilled. However, going back to the 80's every Toyota product and Lexus product I have owned that states the engine takes 4.5 Qts, 6.6 Qts, and the Lexus AWD takes 9.5 Qts the dealers always fill them up to the next full quart, i.e. 5, 7, 10. I have asked about it in the past and they say no big deal. There have been about 4 different dealers involved in this. Besides, if something happens because of this they are liable and they do not seem to care. Now one time they left it 1 Quart short and I complained and they fired the guy on the spot. I have been driving Toyota products all these years and never had any problems. I am a little old and have been driving for 55 years and never had an engine problem. When I used to do my own changes I was very specific about the amount of oil I put in.
