Re: Oil question
Its depends on your Oil Clearences like already stated as to what weight you want to run. Living in a warmer climate will allow a little thicker with stock clearence. My motor is loose i run 20w50 Joe Gibbs XP6 synthetic motor oil. Its not cheap but When your dealing with a motor you drop thousands of dollars into why cheap out on oil. The Joe gibbs has lots and lot of what matters most in an engine, particularly in the vtec engines.
You'll see cam journal wear on todays standard oils as the zinc and phosphorous addatives are drastically decrease in todays oils and there just isnt enough protection.

Re: Oil question
Well, my clearances are stock. Probably worn a little too. So that was my question. The warmer climate is also a big thing. I guess I will call them up and see what they would suggest. Usually companies like this are all about suggesting the proper product for a specific set up.

Re: Oil question
I run 20-50W Kendall GT1, or VR1 in the summer , Delvac 15-40 in the cooler weather.
Directly from the Hot Rod article, June 2006, When Good Cams Go Bad:
SH API oil rating 1996
zinc = 0.130%, 1130ppm (parts per million)
phosphorous = 0.120%, 1120ppm
SJ API oil rating 2001
and
SL API oil rating 2004
zinc = 0.110%, 1100ppm
phosphorous = 0.100%, 1000ppm
SM API oil rating 2005
zinc = 0.087%, 870ppm
phosphorous = 0.080%, 800ppm
SM API oil rating 2007
zinc = 0.060%, 600ppm
phosphorous = 0.080%, 800ppm
Cosworth Racing Oil
zinc = 0.125%, 1250ppm
phosphorous = 0.115%, 1150ppm
Shell Rotella T CI-4
zinc = 0.140%, 1400ppm
phosphorous = 0.130%, 1300ppm
Pennzoil 25W-50 Racing Oil
zinc = 0.196%, 1960ppm
phosphorous = 0.180%, 1800ppm
Quaker State Q Racing Synthetic
zinc = 0.200%, 2000ppm
phosphorous = 0.180%, 1800ppm
Obviously, the 4 oils above do not have an API rating for newer engines. Their rating would be SH or SG. Pennzoil Racing is SG. Rotella is SH/SJ.
From the Kendall website for GT-1, which I've used since 1964 and now can no longer use for fear of cam and lifter damage:
additional spec. for oils of interest:

zinc = 0.200%, 2000ppm

Kendall GT-1 amber 40W. Older green GT-1 used in Thunder and still have 5 quarts of the green oil left. New GT-1 color is amber. Green GT-1 has high zinc and phosphorous content. Amber GT-1 has low content.
zinc = 0.104%, 1040ppm

Re: Oil question
do you have aftermarket higher lift camshafts.
i ran eneos 5w30, untill i put gsc n1's in. now its evident that, that oil is not efficient. the higher oil temps are makin it hard to keep the ect's down. ect's have been higher ever since i swapped the cams. thus inadequate oil properties, weight, and zinc.

Re: Oil question
TheShodan link is kind of old. New oil classification is SN, better for turbo and E85.

Re: Dumb question
Depends upon how you have the bearings set, (loose or tight), what turbo you're using, and what the use of the car is. Also, the use of E85 has its own properties, so depending upon the use, you may need to avoid a few types of oil.
I typically do not recommend mobile 1 synthetic. For the journal bearing versions, something with good zinc content for the thrust bearings of the turbo..
So, Brad Penn, Valvoline VR1 "blue" oil, are good places to start, as well Shell Rotella oil is good for E85 as well.
This chart gives the better recommendations for oil. although the weights of the oil are a little more tailored for loose-bearing-fit DSMs, the companies and uses are solid.

Read this. Its a long article but very informative on what oil really is the best. Actually, most high zinc content oils didn't perform well at all.
