I would strongly recommend seeking out another lab at the time of your next sample as there are a few things on your sample that do not wash. Your TBN was at 0.5 and your Oxidation/Nitration 0%? Also, Fuel Dilution was reported to be 0% - ask the lab if they actually checked for fuel dilution and how, you might find their answer interesting. I spoke with a lab technician who told me that they only check this for diesels. Do not be surprised if you hear "it is really difficult to check for fuel dilution with gasoline" as another lab explained to me when asked. They never did come right out and say that they did not test for fuel dilution, but that was the answer they gave me! I personally do not look at price anymore when choosing a lab as I have found that you get what you pay for. I do not know if anyone has covered this already but....I would recommend using bypass filtration on these engines in addition to a good quality oil. There are many good bypass filters on the market that employ compressed cellulose as the main filter media, and they have been proven to be extremely beneficial in removing water from oil before it can react with acids/contaminants. Anything that can help your oil out here should not be considered overkill.
#870 of 877 Sorry by jj35 May 05, 2002 (7:30 am)
I am really sorry to see this forum close. I am surprised, as well, because I thought that Toyota was using this Town Hall board to better respond to customer complaints and issues. There are many people who are more comfortable with the feeling of anonymity of the internet than they are with a phone call to a customer service rep. I am sure that Toyota will be missing out on a great opportunity to continue dialogue with a segment of their customer-base that would otherwise be overlooked. I wish that Toyota had formulated a response to the concerns conveyed in regards to pdalpshers post of engine oil analysis. It fits right in with what bobistheoilguy has been saying happens to engine oil with the meshed gears in Toyota's. Thank you, bob, for providing a forum where we can continue this discussion.
#871 of 877 Oil wearing out by barbz May 05, 2002 (8:45 am)
I would like to know more about the oil wearing out so soon. I was hoping I could buy the new part Toyota has but it sounds like there is more to the problem.
#872 of 877 Oil wearing out... by webguyster May 05, 2002 (8:58 am)
As we (at least me) have learned, we have "High Performance engines!" LOL! I now feel better knowing my maintenance schedule in my Solara should be comparable to a Ferrari! Makes me feel like I have a true sport coupe! 8^)

jj35 -- I think Toyota already did respond to the oil breakdown theory. Also as far as I can see, they did respond to any Toyota owner's legitimate complaint, at least to any who showed up here and wanted to get to some resolution of their problem. I'm sure there will be other discussion about Toyotas in other boards and forums in case more owners show up in the future. Also, this forum will be permanently archived and we can refer people to it. The archive will have both the permanent "hot line numbers" and e-mail addresses posted in #742 for those more comfortable with that.
#874 of 877 Question by jj35 May 06, 2002 (3:29 pm)
Since this site is not closed out yet, thought I would try one more question. Can anyone explain what was changed in the design of the 1997 V-6 and 4 cyl. engines as described here on Edmunds? http://www.edmunds.com/reviews/generations/articles/46002/article.html
#875 of 877 Change In 1997 V6 And 4 Cyl. Engines by pilot13 May 07, 2002 (3:59 am)
As stated in the article, there were minor (in the range of 3-4%) horsepower increases in both engines. I believe the subject of "design changes" in these engines has been discussed many, many times already. There were no fundamental "design changes" in that year. The relatively small horsepower increases mentioned in the article could easily be accomplished in other ways. As I said, this is not a new question. It has already been addressed in previous discussions. If the question is being asked in an attempt to connect to the sludge issue, it's already been shown there's no connection whatsoever.
#877 of 877 all quiet on the Western Front by Mr_Shiftright HOST May 09, 2002 (5:24 am)
Okay, this forum seems to have gone quiet, so I'm going to put it on "Read only" for a few days and then ARCHIVE it permanently, where it will be accessible to anyone who logs on to this board. Thank you all for your participation. MrShiftright Host
