I read that long thread about which oil grade is best for the new
Acuras (which Acura specifies to use 5W-20) and I decided to use
Mobil1 0W-30 for my 2003 TL. I agree with the reasoning that
metallurgy hasn't changed and fuel economy seems to be the reason for
recommending the thin oil. Also they recommend 5W-30 for the same
engine in different countries. Anoither thing I think about is how
some European manufacturers are recommending 5W-40 for their new cars.

BTW, my father has a big Mercury sedan, about a 2000 or 2001 model,
and the oil fill cap on it says 5W-20. So I guess Honda/Acura isn't
the only manufacturer recomending the thin oil.

Honda and Ford are the only two I am aware right now.

Here's some more information: My parent's cars, a 2002 Acura TL and a
2002 Mecury Grand Marquis LS, both are supposed to get 5W-20 oil, both
have had their oil changes at the dealer at the recommended intervals,
both have less than 18 thousand miles, and both blow blue smoke when
first started in the morning (the cars, not my parents!).

5W-anything provides superior protection for cold weather starts and
easier starting (less starter wear). 5W-30, for example, will let you start
in Wisconsin's winters without an oil or engine heater. 10w- .. . no way.
Today's closer engine tolerances (for emissions, power and economy) require
better "start" lubrication. On the other hand, my inherited '85 Buick
LeSabre runs best on 5w-30 synthetic, which wasn't around when the car was
built. As long as you have an API & Milspec approved oil, just follow the
manufacturer's temperature recommendation for your area of the world.
