A guy I work with just bought an '08 Toyota Tacoma, extended cab, 4x4,
auto, etc. He said that the "dealership" told him that if he switches to
Mobil 1 or any synthetic oil, that it will void his warranty. Sounds like
total BS to me but thought I would toss this out to the experts before I
begin surfing for other answers. Thanks and I appreciate your feedback.

It is total BS. It will not void the warranty.

However, most knowledgeable people would recommend that you wait about 5k -
10K miles before switching to synthetic on a new car. This is because you
want to some engine wear to occur so the piston rings will "seat" properly
before you start using synthetic (which in some cases is so slippery that
you don't get engine wear for the seating to take place).

I've heard this mentioned before but then it makes me wonder why Corvette's,
BMW's, etc. come stock with synthetic. Anyway, thanks for the response!

The fact is that when they first made synthetic factory fill in the Corvette
they did had problems with piston ring seating. I am not sure what they did
to fix it, but obviously if synthetic is factory fill then it is OK.

I can tell you from my own experience that I switched to Mobil 1 synthetic
on my 1998 Camry V6 at 5K miles and now I have a problem. The engine is so
smooth after more than 10 years that I can't find any justification to buy a
new car.

Since Toyota actually sells Full Synthetic Oil, I think I'd go back to the
dealer and tell them to go to H*&l. The Toyota 0W-20 full synthetic oil part
number is 00920-1QT0W-01 ($5.96 a quart from on-line Toyota parts stores).

The following web page is from a Toyota of Canada Web Site:

http://www.toyota.ca/cgi-bin/WebObjects/WWW.woa/29/wo/lCkqPpSPXu0Ep4Qc2kTni0/5.7?o400140e%2ehtml

This Toyota web site has lots of wonderful things to say about Full
Synthetic Oil and I quote:

---Begin Quote---

WHAT IS IT?
.. Conventional oils are refined from base stocks, whereas synthetic oil is
man made by combining specific chemicals to produce a synthetic base stock

WHY DOES IT DO?
.. Synthetic oil protects your engine and performs better in both cold and
hot temperatures
.. Reduces engine friction more effectively, especially at low temperatures,
thereby increasing horsepower and decreasing fuel consumption
.. Synthetic oil minimizes on-going wear and deterioration and extends engine
life

WHEN TO REPLACE?
.. The oil and filter should be changed according to the Toyota Maintenance
Menu

FEATURES
.. Pour point of -51�C means it keeps flowing even at very low temperatures
.. Withstands the extremes of very high engine temperatures without thermal
breakdown and maintains viscosity control
.. Excellent low and high temperature performance combine to produce a single
all-season lubricant suitable for the extremes of the Canadian climate

---End Quote---

I guess only Canadians actually need synthetic oil.
