I have about 37 K miles on my 04 and no oil leaks. I do have a 6-speed, but then you said that the auto-trannie was not leaking.
I swithced from Castrol dino oil to Mobil 1 at 7,500 miles. The synthetic motor oil is supposed to increase the probability of oil leaks.

Myth #1: Synthetic motor oils damage seals.
Untrue. It would be foolhardy for lubricant manufacturers to build a product that is incompatible with seals. The composition of seals presents problems that both petroleum oils and synthetics must overcome. Made from elastomers, seals are inherently difficult to standardize.
Ultimately it is the additive mix in the oil that counts. Additives to control seal swell, shrinkage and hardening are required, whether it be a synthetic or petroleum product that is being produced.

the guy said that it was a tranny seal but did not specify
because he didnt know, (he was not the tech.) we'll see what happens

in older motors with unconditioned seals which are caked to prevent leaking.... Syn will clean them and expose the always present leak.

It is true BUT it only defects the seals from an OLD engine with high millage.
I.e = 100k engines to 75k engines. In the long run it would cause the seal to be eaten up by the Syn oil because of the detergent that it has in it.

read my post. why in the world would any company add something to eat up your seals?
what's the company care if it destroys the seals after driving the car for 100k.. be hard to link to the oil and really, its not their problem...
Don't give companies too much credit when it comes to "not wanting to hurt the customer".. so long as it doesnt affect their bottom line, what's it matter.
Not saying that this is the case here... but just to counter your argument
