My cousin is a chemical engineer for one of the big 3 auto makers and when I called him about the synthetic getting better with age, he stated that they performed many tests on cars using all types of oils and NO WAY do oils get better as they age. They found synthetic protects better from day one and continue to protect and lubricate best between recommended changes.I guess this explains why the vehicles I've owned over the years have gone at least 100k and some over 200k w/no significant oil consumption between changes.

I guess what it boils down to, is change your oil regularly, no matter what you use for oil, and you'll get plenty of miles from your vehicle.
I used regular oil in my Park AVenues and got 331,000 on one of them, AND it didn't burn any oil still.
My other Park avenue's both had high miles (but I got rid of them for the Avalon:)

A Toyota dealership mechanic told me and he said that one can get away with every 10K when using synthetic. I was wondering if the Avalon warrantee stipulated the frequency of synthetic oil changes.

Clicking / Grinding noise in front end?

Or so it seems.
When my 2008 Avalon is cold, and I first drive off, there is a clicking / grinding sound that seems to come from the left front corner. Much like if the CV joint was bad?
The car has 3,500 miles on it.
The noise is MUCH worst when taking off and turning left right from the start. So I start the car up, and turn hard left under acceleration and it makes the noise.
The noise or frequency is less after about 10 - 20 minutes. If I park the car long enough for the parts / car to cool down, it happens each time.
The car also seems to be shifting or not, much more during this time. I have on occasion been going down a very slight incline and had the car almost stop when I let up off of the gas pedal. It's like the car is in low gear when I do this, even if I'm going 25 - 35 MPH.
The car was in last week for this, and at that time they said they has to re-set the VCS sensor?
All pretty weird, and folks had this happen to them?
Is there something I should tell me dealer?
I'm guessing the worst that can happen is it gets worst, and the dealer can then figure out what's wrong?
I say this, because they didn't hear anything yesterday when I dropped the car off, for them to check out.
I'm thinking I'll need to leave it there over night for them to hear and maybe figure out what's wrong.

I also have an 08 but have not experienced this issue.
Definitely leave it over night at the dealer.

The noise that I get (it seems when it is cold) is a popping sound that seems to come from where the windshield meets the dashboard on the drivers side.

I don't know about the grinding noise, but on the transmission issue, the Avalon does have some issues. My cousin has a 2005 Avalon Limited, and the transmission does occasionally has to be 're-flashed' they call it. Sometimes the transmission will do a weird shift, or seems to get stuck, only for a couple of seconds. I personally think Toyota should have addressed this problem before they keep sticking this flawed transmission into their cars.

Not defending Toyota but the transmission in the 2008 is a new 6speed and is completely different than the 2005. I owned both and the difference in driveability is amazing. However, Toyota apparently not properly address an issue around the junction of the steering box and column. There were "bad welds" but this is more likely a design issues. They had to replace the steering box in my 2005 due to the very same clicking/grinding sound described here. There was even a TSB. You might want to ask them to check this.
