Dealer Wanted to Add 5 Qts on Oil Change
The A1 service came due at 5,700 miles so I decided to give the Acura dealership's service department a try. I wanted to use my own oil and filter and the service writer said no problem. An appointmet was made and the dealer got my TL in to the shop as soon as I arrived.
According to the owner's manual, the TL requires 4.5 qts with an oil and filter change. So, I provided them with 4 qts of my own oil and stated that I would take care of topping it off.
When they finished with the TL and I was checking out, the service writer stated that the technician said that the TL really takes just over 5 qts. This meant my TL was down over 1 qt on the dipstick and I should add an additional qt as soon as possible. They also indicated that on the receipt. If I had had an extra qt with me, I would have added it on the spot but I didn't so I proceeded to go the 7 miles back home. At home, I let the TL sit for 10 minutes in my level garage. Then, I checked the dipstick and discovered that instead of reading below the 1 qt low line, in fact it was down less than 1/3 qt. So, I did not add any oil at all.
Questions:
1. How much oil have others actually been adding with an oil and filter change?
2. If had proceeded with adding the 5th qt and essentially overfilled my TL by at least 2/3 qt, how much actual damage would have been done?
3. How big of a issue should I make with the dealership on the fact that they apparently don't know the true capacities of the vehicles they service?
Thanks for all inputs and recommendations!

I added 4.5 quarts. Not sure if an extra .5 quarts (5 total) would raise the level enough to cause a churning issue, but probably not. It would just be a waste. I haven't had to add oil between changes. I'll save the 1/2 quart for the next change.

Synthetic oil is a pure waste of money unless living in a Nordic climate. Engines on regular oil routinely gets 250 000+ miles. You really need more than that?

Haven't changed the oil on my 04 yet but my 00 was the same engine. I always changed it myself and always used 4.5 quarts. Never had a problem and it always read full. Stick to the manual.

I use Mobil 1 and supply my own oil for the same reason listed above. Price of oil at the dealer is a rip.
For the original question. The mechanic may have spilled some oil and required more to replace it, but of course they would not admit that.
Is the 4.5 qts the capacity with or without the oil filter? The filter generally adds capacity.

Don't you realize that for some, the use of synthetic oil is like a religion? A believe or die thing. To the point it is ridiculous. Don't you have anything else really important to care about?

I used synthetics in my old cars becuase I was not religious about oil changes. I would go as soon as it was convenient after I passed the 12K mark. Fewer oil changes was always a plus for me.
I'll use the Honda standard now since synthetic will not buy me anything with the oil life indicator in the TL.

Not a Blowhole
Several issues at play here:
1) I doubt 5.0 qts will cause an overfill. Most cars can be "overfilled", because the mfr's allow for it, as some nimrod will always overfill by a quart. Plus, mfrs often under-rate the capacity of the oil sump, so they can reduce the TCO $'s. On the S2000 Forum, some guys went on and on for pages about the little "X's" on the dipstick, and whether 1 x over would cause engine failure, whether to read the front X or the other side X, and so on - it was nuts!
All quality oils have silicone in them, to reduce foaming (like DiGel for your tummy). One can easily check for an overfill by running the car up to redline (under load - don't do that when at idle in neutral!!!!), then shutting down, and immediately checking the dipstick - you should not see foam, or even lots of bubbles. If you do, you ARE overfilled, and should slightly loosen the plug or pump it out through the dipstick.
2) Regarding synthetic oil being a rip. There is partial truth in this, but like anything, one liners are usually only half truths. Beware the one-liner bearing a grudge.
I have posted before that 20 years ago, synoils were unquestionably the way to go for high performance cars and high perf owners. Today, modern oil refining (hydro-cracking and hydroisomerization) has resulted in Group III oils, which are partially saturated, and near synthetic performance (synoils are fully saturated, being mono-molecular). But GIII's are not as goofd at low temps, as they still have wax crystals, and as they heat cycle, they start to "un-refine" - the heat acts liek the heat of refining, only in reverse. And the importance of the add pack cannot be ignored, either. Most minoils from the best companies (Chevron(Havoline), Motocraft (Conoco)) use similar anti-wear (AW) and anti-friction (AF) compounds.
Point is, the gap has closed -minoils are an order of magnitude better, and synoils have not become 10x better than they were.
But, generally, a quality synoil will outperform a mineral oil in:
1) detergency
2) lowering friction
3) cooling the bottom 2/3 of the engine
4) lower volatility (meaning less thickening and less boil-off requiring makeup
5) Service life
6) Generates less self-induced crud since it is not refined, it is created, molecule by molecule. Soemtimes it comes from petroleum, or natural gases, or from the synthesis of acids and alcohols, such as from corn (esters)
7) Reduced wear at frequency extremes
8) Higher flash point (see #4)
9) etc. etc.
It certainly is true that today's best minoils, used within their service limits, are all the lubrication most people need.
It is certainly true that quality synblends like Motocraft 5w20 can offer performance at or beytter than some other full synoils. It is a question of good lube engineering.
It is certainly true that a synblend like LE 8130 can arguably be the best oil on the planet, as it uses the best qualities of both mid-continent paraffins (GII), and GIV PAO's. Its add pack allows extende drains, and paraffins seem to work better with thr add pack than some straight synoils. I will post a link to something you all should read, to see in one post where all of what I have said can be verified by standard ASTM tests.

Plus, all racing teams use synoils, and often not the ones emblazoned on their cars and race suits.
I do not mind your quoting one line to support your position, as much of what I posted does support your overall contention, just not the flippant one liner. The choice of engine oil is imprtant, and people should make an informed choice. Between the 2 of us, much info to that end has been shared. It's all good, bro.

Well, I know you seem to like snap answers, but quoting out of context here is a bit disingenuous, don't you think?
Fact is that oil industry has never been able to prove any longer durability of engines with synth oil. It was all their interest to try and try... Again, it is a believe it or die thing. Pure waste of money.
Personally, I have seen cars with once a year dino-oil change to last 17 and 19 years with original powertrain. One was crashed and the other resold.
I think that this synth oil phenomena comes under the chapter of "people who are scared to be scared".

Well, Saintor, you seem to know what you know. But what are racers afraid of, I wonder? They are looking for any edge - what "religion" - are they too ignorant of the facts? And did you read the ASTM test results I posted?
Mobil and others have submitted papers showing wear reduction in controlled tests to the SAE, and those go through peer review - I guess the test procedures where they show virtually no wear after 300k miles, or reduced wear scars for the same loads, have no real-world applicability? And the engineers that per-reviewed them lack analytical faculties to "see-through" the hype.
Again, you and I agree on much, but I think you see things as black and white, but in this context, grey is real, and for many owners, grey works. Anecdotes about cars lasting 20 years are fine, but science deals with N. I know a guy who claims he never changed the oil in his car, and it lasted for 200k miles. Does that prove synoils are not necessary? Or that not changing the oil is worthwhile? Does it prove anything at all? Not to me.
Let's leave it at that, and let those who have followed this thread infer what they will, and make their own decisions based on whatever they will - but most of the engineers I know who have expensive sedans, let alone sports cars, and certainly all that race, use synoils in the engine, tranny, and diff. I use them in my S2000 except the diff, where i found LE-607 to have the highest load carrying capacity of any diff oil I have ever tested. It was relatively unknown in the passenger car world, and now it seems to be the diff oil of choice for many (point is, I am not a blind zealot - I am a scientist who uses the discipline of science to make informed choices).

NYC taxis do 300000 miles routinely on the same powertrain on dino oil. Same goes for the 1 080 000 miles Accord 1994. Asking for more is overkill for 99% of the people.
I disagree about the gray zone. A determination has to be made if there are obvious benefits of using synth oil (not in racing, neither in polar temperatures), enough to recommend it.
None so far.

I've used Redline engine/tranny oil (RR, I noticed that the min-syn oil comparo didn't include Redline; any reason why?) in all my cars. I don't use it because I want the car to last 800,000 miles instead of 400,000. I've seen tests that show reduced friction with Redline, thereby, theoretically, freeing up some power. Now I know it isn't a lot, but hey, every little bit counts, eh?

Road Rage: I see above you say you wouldnt run 8K on Honda's stock oil, but I thought I also remember reading somewhere in here that you shouldnt switch to Syn for the first couple hundred/thousand miles as it helps to properly break in the engine.
If both facts are true, what would you reccomend for a MinOil to use in place of the honda stuff? Or would you just stick it out until the first oil change at a few thousand miles and then switch to Syn?
EDIT: Re-Reading my own post and suddenly feel stupid. 8K = miles or RPM?

I would argue that Syn Oil *IS* a waste after spending $807 on a head gasket job for my Audi before I sold it (I used Mobil 1 for all but 3000 of the 81,000 miles). Who honestly pushes a car far enough (or lets a car sit long enough) to justify $5-6/quart ?

RE: Red Line. I do not know why they were not in the test - probably because they are relatively small player compared to the others. I have used Red Line in various applications for many years, but I think several others have caught up or surpassed them, and those are in my recommendations. Esters are fine, but base stocks are only part of the making of a great oil - add packs make or break it. On BITOG, there have been some posts on Hondas showing elevated copper in the used oil with Red Line- some say it is because the RL leeches wear metals out with its high detergency, others say it is something to be concerned over, since other synoils do not seem to do it. Esters can cause hydrolysis, and whenb watre gets in with the oil, bad things happen - so do a routine UOA now and then to check for coolant leakage. Esters also have to use some PAO to offset each other;s tendency to swell/shrink seals. Thrust bearing and crank brearings use copper in the Hondas I recall, so this mystery is quite important. I do not plan to do the guinea pig.
But RL is a fine company, and I like their MTL and MT-90 in my S2000's tranny - I have not liked their ATF's though, and they do not make one for the TL - Amsoil does.
The one real benefit of esters is that their intrinsic magnetic polarity charge makes them stick to metal - gravity never pulls all the oil off the cam lobes, the highest stress opints durintg start-up. So if you run your cars rarely, that may be a real plus.
It allk comes down to choices, and for mem based on many hours of thought and countless analyses and measurements, that I am going with LE 8130. I have asked LE to consider making a 5w20 synblend, and they are considering it. That would make the warranty fraidy-cats happy.

Usually a head gasket failing results from overheating, not from the use of a type of oil. Your cooling system probably had something to do with your head gasket failure.

"Synthetic Oil" is a sham from a marketing stand point, not necessarily from its effective use.
What do you suppose they make "synthetic" oil from??? The same crude oil all lubricants are made from. The expense is from the extra refining and detergents.
Laugh if you want, but I Z-Max my cars. I put it in my Celica the day I bought it and the oil was the same carmel brown coming out as it was put in 6000 miles earlier. So I stuck with that until my car was killed by an SUV last April. Same story everytime. The lube tech onced asked me if I was changing it more frequently, cause it was never dirty.
So on July 3rd, with only 2 miles on the odometer, I Z-Maxed my TL before it rolled off the dealer's lot.
