Pete: Drive the vehicle normally. Change the oil and filter at three
thousand miles. I would not begin to use a synthetic lubricant until ten
thousand miles. You definitely want the components of the motor (piston
rings, pistons, ect.) to seat in. Synthetic oil will increase the amount
of time and even may not allow parts the required break in. Synthetic
lubricants are very good, but it's the frequency of change of the engine
lubricant that will extend engine life no matter what type lubricant.
Always change the filter as well. Check the Toyota manual for any
special procedures during break in and you should enjoy the vehicle for
many, many miles. IMHO. Good luck.

The Corvette and a number of other cars come with Mobil 1. What you are
saying is nonsense. There is no need to wait until you start using a good
synthetic.

But there is no advantage to changing your oil more often than recommended.
Mobil 1 makes a lubricant that you only need to change every 15,000 mi. More
often than that, and you are wasting your money.

The link below is the used oil analysis for our 2004 Lexus RX330 with
Mobil 1 5W30 extended performance (EP) and a Mobil 1 EP oil filter.
The oil had 6,600 miles on it and the TBN was shot. There is no way
the oil would have made 15,000 miles. I had a previous interval of
8,600 miles (all highway on a cross-country trip) and it was even
worse, which is why I went back 6,600 miles this run.

Also, since Mobil 1 has reportedly moved from a Group IV to a Group
III oil (but still charging the same amount -- ala Castrol Syntec back
in the 1990s), it is time to move on to another product.
So, the next change is Pennzoil Platinum, 5W30. We will see how it
does in our RX.

If you notice, according the people who made the report, the Toyota engine
tends to deplete the TBN. That's not Mobil's fault.
I also like the comment about ExxonMobil's huge profits. I doubt they came
mostly from Mobil1.

I'd rather waste a couple hundred bucks over the life of a car, than waste
a $4,000 engine...
