Amsoil Synthetic. 5W-30 or 10W-30
I live in Southern California. Temperatures range from 40F at night to 98F during the day. What synthetic should I use.. 5W or 10W.
Also, for an auto transmission what transmission fluid should I use (Redline?).

Actually, 5W-30 has the wider range of use because its thinner in the cold... However, reading the lovely book that Nissan provides with each Maxima, shows that 5W-30 is "preferred" for all temperature ranges. It then states that if the ambient temperature is above 0 degrees F all the time, then 10W-30 is good.. Personally, in CA I'd use the 10W-30 because it will be thicker on cold start ups (or when car hasn't been used for a while) and protect better until the oil reaches operating temperature. However, with synthetics like Amsoil and Mobil 1 that don't use thinners in the 5W oil, the protection is about the same at cold start up so that you are still protected.

I wonder where Bill is....I want to prove I actually read these oil threads almost like religious text!

What you're missing is the California part. It just doesn't get cold there. With a low temp of 40 degrees, I would definitely use 10W/30. 10W flows fine at 40 degrees and you will have a slightly thicker oil when cold than a 5W/30, which will actually reduce wear at startup since a heavier oil at cold temps is being used. The example of not running a car for a few days is a good example. As long as it doesn't get below freezing, using 5W/30 doesn't offer any advantages over a 10W/30.

1BADMAX... I didn't say 10W-30 was a type of transmission fluid!
The term "ALSO" was used...
Very funny... since on my other post you also said "By the UDP has nothing to do with the y-pipe"...
You need to read my posts better, your making me sound like an idiot. I didn't think a UDP had anything to do with a Y-Pipe and I didn't say tranny fluid comes in 10W... Are you doing this on purpose

or a catback (isnt it pointless without a y-pipe?)
so 10W-30 is perfectly fine even if sometimes it reaches 37F?
And is redline tranny fluid good for auto?
and where the hell do i buy Amzoil.. is that what you people recommend?
