5w 30 or 10w 30 Oil?
The oil has a green tint to it. If you read the reports it has the consistency of a 40W which is great for our engines.

I stay away from Pennzoil, Quaker State and other "paraffinic"
oils because I found a thick layer of waxy stuff in one of my
motors on teardown, when I was much younger. I used to use
Pennzoil exclusively up to that point.
I use the "German Castrol" now, mainly liking the full synthetic
in case I forget to change it for a bit. The price (on sale) was
near regular oils.

Everyone has their own opinions about oil. I've owned 6 Z28's, all used Mobil 1 and the internals looked amazing after 90k miles.
Let's address the clueless comment tho just for the hell of it. Show me proof that Amsoil, RP, and Redline are better.
PS: I think that desert heat might be getting to you

5w 30 5w 30 is the preferred oil the moter turns over easier compared to the 10w30
because the first # is liter. reguardless of outside temps.
look at the oils that porshe, viper, vette come with moblie 1.
I have tryed the castrol syn. (only because moblie one was sold out) I noticed an obvious smelly smell I did'nt like.
main thing is change it (whatever oil) before it turns funky

Been using M1 for years in all of my vehicles and not ever a problem. All this "M1 is junk" stuff is bull. It is still the factory fill in more high performance cars than any other, and you can find it easily. I'm sure the GC is a fine oil, but I'm not changing to it. In reference to your question, I use the 10W30 in my southern climate.

ok heres a question for all the GC 0w-30 users. what is your oil pressure at 60 mph in OD gear? im at around 45-50 psi at 2000 RPM(stock 3.23's). i use 10-40 Mobil 1 synthetic high mileage. i need some evidence of something better than a review if im gonna change to German Castrol sorry!!!
