#10498 of 10987 Mystery oil consumption - 2002 Highlander V6
Apr 15, 2006 (2:58 pm)
I have a 2002 Toyota Highlander V6 with 130,000 miles which had exhibited negligible oil consumption between oil changes -- that is, until about a month ago.
Just as I was arriving home from work, I saw the low oil pressure light blip on for a moment. When I checked the oil level, I found almost nothing was showing on the dipstick!
I refilled it to the full line and have been monitoring it every few days, checking it first thing in the morning before starting to make it easy to see the oil on the dipstick.
It is using about 1 quart of oil (Mobil 1 synthetic - I've used synthetic oil since the 10,000 mile mark) every 5,000 miles now after using nothing during the first 120,000 miles. There are no visible leaks, and I don't see anything unusual with the exhaust to show oil consumption.
Any idea where the 1 quart of oil every 5,000 miles is going?

No idea but no one will tell you that 1 qt per 5000 miles is excessive. I certainly wouldn't worry about it.

I would imagine there is some oil blowing by the rings which are bound to have some wear after 100K plus miles. One quart in 5K is excellent and perfectly normal.

I think the catalytic converter can take care of that little amount of oil and you won't see it smoke.

A sudden increase in oil consumption sounds unlikely to be rings. More likely a crankcase breather pipe disconnected or a valve blocked resulting in pressurisation of the crankcase blowing oil mist into the inlet manifold
Get a Toyota dealer to check it out. Might be much cheaper than you think
#10503 of 10987 Weird Noise 2004 V4 Highlander

#10504 of 10987 Canadian Centre Console
Apr 20, 2006 (5:30 pm)
Do any of our Canadian members know when the centre console became standard on all Canadian HLs? My understanding is it was introduced in 2002 on the more expensive option, and became standard on all Canadian HLs sometime after this. Does anyone know what year it became standard on all Canadian HLs?
Also, does anyone know when the HL (Kluger) was introduced in Japan? Was it in mid-2002 as a 2001 model like the U.S. version?

If memory serves me, the HL was released late in 2000 / early 2001 as a 2001 model in North America. The centre console was made standard in 2003 (Canada). The Kluger was released approx. 6 months earlier than the HL in Japan. This information is based on an aging mind.
#10506 of 10987 Wikipedia Entry for Highlander
Apr 23, 2006 (9:36 pm)
I just discovered Wikipedia from an individual contributor standpoint, i.e., I made some minor corrections and additions to the entry for Toyota Highlander. Please review for accuracy and either let me know if you see any inaccuracies or feel free to make the changes yourself!
(The entry originally stated the center console was introduced in 2004 whereas it was introduced in 2002; it incorrectly implied the HL went on sale in the U.S. in 2000 whereas it actually went on sale in early 2001; it didn't mention the new Sport model; it implied 4cyl models are only available in FWD for all model years whereas to my knowledge this is only the case for '06s. Somewhat minor stuff but I cleaned it up.
There is a sentence in there that states "Base models are equipped with a limited slip differential, with stability control providing slip control for more expensive derivatives." I'm not sure if this is indeed technically accurate or whether it's true for all model years, so if not it should probably be changed.)
Wikipedia can become a time sink if you're not careful!
(For those who aren't familar with it Wikipedia is an online encyclopedia that is entirely maintained by anyone on the web who wants to make changes to it, unlike traditional encyclopedias like Britanica and Encarta that are written by paid professionals. You don't even have to set-up a user account or log-in if you don't want to! I read an article or heard on the radio recently that it was found to have error rates similar to those of traditional encyclopedias.)
#10507 of 10987 Inferior Nav System on 2006 Highlanders
Apr 27, 2006 (12:21 pm)
Due to my dissatisfaction with the screen resolution on the Navigation System in my new '06 Highlander Limited, I was invited to bring it into the dealership where it had been purchased in late 2005 (Hayward Toyota in Hayward, CA). This followed an exchange of emails with the Toyota website (http://www.toyota.com/), resulting in Toyota contacting the Customer Relations Manager at the dealership, who asked me to bring in the vehicle to have it checked out. I did so in April 2006 and learned something very interesting:
It turns out the Nav System in the 2006 Highlander is an older generation, unlike that which is placed into the Prius. It has lower screen resolution (and presumably other older generation features) by design. The lower screen resolution results in jagged lines for roads and difficult to read street names on the maps. Interestingly enough, during my purchase process when I mentioned the "dot-matrix like" fonts on the Nav maps, the salesman at Hayward Toyota made 2 comments:
(1) "Oh, the Nav in my Prius looks just the same."
(2) "You just need to increase the brightness of the screen."
Both of these statements, made by the salesman (at the time, Fleet Service Manager) in November 2005, turned out to be false.
Flash forward to April 2006 and I am sitting in the Service Manager's office at Hayward Toyota (Hayward, CA), expressing my disappointment with this situation. The Service Manager was polite and offered to phone a Toyota "engineer" to air my complaint. I was amazed to hear the engineer state that the Nav units going into 2006 Highlanders (presumably even the hybrids) are "Gen 4" (short for Generation 4), while those going into the 2006 Prius are "Gen 5." He went on to say that Gen 5 Nav units were much better than Gen 4 but Toyota elected not to install the better units in 2006 Highlanders.
Now when one spends an extra $2000 for an electronic accessory (e.g., the Nav System), it would be reasonable to assume that the "latest and greatest" version would be installed. In fact, when one buys a new vehicle from an authorized dealer, it sure seems reasonable to me to expect that it comes with current technology. This would seem to especially true if one purchases a more expensive trim line (we bought a V6, Limited [leather seats, moon roof, aluminum wheels, etc.]). This obviously was not the case with the Nav System Toyota selected to go into the '06 Highlander. I wonder what other inferior systems, my Highlander contains ...
Since 1999, between my wife and I, our family has purchased 4 new vehicles from Toyota dealerships. Our purchase considerations were based on the excellent track record which Toyota has established and the trust which we had placed in the firm's integrity. The only other manufacturer we considered was Honda, from which I had purchased several cars in the late 1980's. I will tell you that Toyota will not be our first choice for future vehicle purchases and we will certainly share this experience with our friends and family. I guess the old saying, "Buyer beware ..." holds true when purchasing a new Toyota.
