Oil Comparisons
MOBIL 1 http://neptune.spacebears.com/cars/s.../oil-life.html
the basic stuff here is:
Anti-wear: molybdenum, phosphorus, zinc
Antifreeze inhibitor: potassium, boron, silicon, sodium
Detergent additive: boron, calcium, magnesium, and barium
AMSOIL http://neptune.spacebears.com/cars/stories/amsoil.html
Anti-wear: NO molybdenum, MORE Zince
Antifreeze inhibitor: less than half as much boron,
Detergent additive: 1/3 less calcium, thirty times more magnesium
that is some info from the text(s)
the comparisons don't say whose better than who....it just states how the oils work and whats different about them...you then can make your decision from that

I bet there is a comparison somewhere with it or at least a writeup about Royal purple. People have made dyno gains with it and the only problem is that you must change it so often
Please share some info with me...whats Patmans comments on this? I want to know b/c I hate debates....people bullshit too much in debates

Royal Purple (5w30) is too thin, and oil analysis has shown it a poor choice for the LS1. The Racing Royal Purple oil is a good choice however.
Mobil 1 5w30 also too thin, I believe in the range of kinematic viscosity 9.5-12 that defines a 30wt oil, its close to 9.5, meaning its viscosity is to thin.
Mobil1 5w40 T&SUV is an awesome choice, showing excellent oil analysis. RP and M1 are thin oils, and stepping to the 40wt (which is thin for a 40wt but falls in our requirement category perfectly) proves well.
Redline 5w30, Certain Amsoil products (can't remember which ones), and of course, german castrol 0w30 are excellent choices as well. Don't use Mobil1 5w30 or RP 5w30, analysis results from blackstone labs has proven them as a bad choice for our engines.

0w30 German Castrol Syntec
Mobil 1 Truck & SUV 5w40
Redline 5w30
Can't go wrong with these. I know Patman would agree (though I don't want to put words in his mouth), and he'd also suggest certain Amsoil products that kick *** as well as he did for me, but I don't know which ones, though one of the good ones is the 5w40 European formula.
please look here....people are getting misinformed about things up on this thread...http://www.mobiloil.com/USA-English/...bil1_5W-30.asp that is the 5w30 mobil1 oil.
now here is the main site for mobil 1 facts http://www.mobiloil.com/USA-English/...l_1_5W-30.aspx
click on each link for your desired oil specs and see for yourselves
CASTROL Vis @100C is 12.2
MOBIL1 Vis @ 100C is 11.3
are they that different?? I mean really(yes i realize that is a difference, even though it is only 1.1)
Also attached are the specs of multiple mobil1 oils and the castrol 0w30 specs
Another good choice is the Amsoil Series 2000 oil, in 0w30. That one is an extended drain interval for severe use, and can go on a 1 year interval.
And for a more cost effective choice, you could go with Amsoil's XL 5w30. I use that oil, and change it every 6 months (once before race season, once after).
If any of you have any questions about Amsoil oil or their new "Absolute Efficiency" oil and air filters, feel free to shoot me a PM.
