We also own a 2000 Avalon...about 80,000 miles. The dealer said that they typically do not replace spark plugs untill around 100,000 miles. They did say that the plugs are hard to get at....which means that "they" should do them. Sorry about the "on-line" service link....I am searching for same.

Hello guys.. a question for you.. This is my first Toyota.. having said that let me say that I bought the car new just 2 months ago.. when I hit 1500 miles I took it in to have the oil changed.. some say its not necessary, but I'm old school and every new engine I've had, I just change the oil at around 1500 to 2000 miles, then again at 5K. Anyway when I changed oil this past weekend I went ahead and used the "toyota" 5w-30 oil and toyota filter. I mentioned to the service writer that my next oil change I would be switching over to Mobil 1 synthetic. He advised me that I shouldn't go to synthetic in toyota until at least 10 to 15 thousand miles. LIke I said, never owned a japaneese engine before, but I know for a fact that Mobil 1 is a factory fill for porches, corvettes and other high performance power plants, so I find it hard to believe that it would damage seals or anything else for that matter on my avy's power plant. any thoughts? thanks

Good morning,
I work in Northern Canada, for one of Canada's largest producers of Synthetic Crude Oil. (450,000BPD) Synthetic oil will not hurt your car from new.
As you mentioned it is a factory fill for many cars.
Where I live we see -45C temps and regular regular oil just won't stay fluid. Synthetic oil is out of the ground just like what you'll here people call Dino oil.
The difference is how it is hydrotreated (removal of sulfur and nitrogen as Hydrogen sulphide gas and ammonia respectively and turning Hydrogen double bonds, into single bonds removing diolefins & olefins which are the waxes in your oil]. The process of upgrading the synthetic oil, also equals a very consistant molecular weight. Which is why it flows well in cold and doesn't break down in heat. They do not need to add as many additives to the oil to make it perform in minus degrees or plus degrees.
Non-synthetic oil may have some molecules that are a weight of 1 and some that are a weight of 100, but the average comes to 5 (this differece increases the need for additives to make the oil exibit the desired weight properties, pour point, flash point, froc point etc...). Where in synt the weight comes very close to 5 across the different cut points of the oil > less need for additives
I know that is alot of detail, but in short Synthetic oil and "regular oil" can come from the same base stock, the difference is in the upgrading. Where I work we extract the oil from sand (oil sand). The difference is how it is treated before it gets to you.
Hope that helps,
Netwon

oiLcan... how long have you used amsoil? In all of my other vehicles I've used Mobil 1 synthetic.. I've heard alot about amsoil, mostly very good reports.. I've also heard alot of people sing the praises of "royal purple".. actually saw that on the shelf at a local gm quick lube place not too long ago, but don't know anything about "purple". I was curious as to how long you go in between oil changes with amsoil? also is it available in most national chain auto stores and why do you prefer it over Mobil 1. Like I said, i've used Mobil 1 for years but that's because it's easy to find and i believe it's a good product.. but that wouldn't prevent me from switching if i thought I could provide better engine protection for my car.

All Toyota's in Alberta, Canada carry Mobil 1 at the dealer level and advertise it as an option (top of the page) Toyota Service Menu. Also I wouldn't recommend changing your oil's grade within the warranty period. 5w30 is what is called for by Toyota. 0w30 and 0w20 are making in roads in the new Rav 4, and next generation engines. But aren't here yet mainstream. As the HP output of the engine is high for its size (268hp vs 3.5L) I would think the higher weight would offer greater protection for your engine. The weight of the oil is its ability to support load, too light not enough protection.

I dont want to be labeled a "amsoil zealot" whatever that is
but I have been using it over 25 years in all my vehicles,
they have a broader range of oils,they make their own oil
and air filters.I am a dealer but mainly to get the oil easier,will get to anyone who wants it for my cost.they do not have a filter for the av yet so I have been using the
toyota one.I will probably change the filter at around the
4 or 5k life of the oil and go from there.(will check color
and maybe take a oil sample).

Personally I use Mobil One (Syncrude Canada where I work is partly owned by them) however I do not have the easy availability of Amsoil to test (400km from Arctic border). I think the Ams is as good (if not better) then any other fully synthetic oil. Understand however that when we ship our synthetic crude it goes to a variety of buyers. Amsoil does not have a crude oil refinery they simply purchase synthetic basestock, and add additives to it and further separate out the differing weights we purchase as consumers.
Bottom line: Use Amsoil or Mobil 1, you are 450% better off then conventional oil if you drive with heavy loads, extream heat conditions or cold conditions. (Or just like me, like to have the peace of mind knowing that your 25k+ baby is looked after to the best of your ability.
Would you agree?

Unless they show you a bulletin from toyota themselves and you should even get a copy of the special bulletin, the owner's manual "ALWAYS" prevails. If he didn't produce an bulletin, he can not force you to do all those things unless they actually need them. Did he threaten your warranty with Toyota? I'd call Toyota cust service and file a complaint. A dealer has no right to threaten to void your warranty by refusing optional service not in the manual.

a quick question for you guys... I have an 07 Avalon xls...when the car hit 1000 miles, i went ahead and had the dealership change the oil and filter using toyotal conventional oil and filter... I told the service writer that I would be switching over to sytnthetic oil probably at around 5K... he told me I shouldnt do it, that I should wait until the car has at least 10 to 15 thousand miles on it...he said i could hurt the seals by going to synthetic. Personally, I have to wonder about that... after all, corvetts, porches, and a number of other high end vehicles come from the factory with synthetic oil in them... why dosn't it hurt thier seals? and is there any reason I should wait for 10 or 15K to switch over?
