Dyno Test German castrol 0-30 VS. Mobile 1 5-30
I was curious about the performance gains that were possible from simply changing motor oil.
My set up
05 C6
Trickflow 22512:1, Comp Cam 236/242 600/610 114, harland sharp roller rockers, Port matched F.A.S.T. Intake, ported TB ,ASP Underdrive, Callaway Honker, LG Long Tube W/highflow cats, ghl stinger
All runs are on the same DynoJet where I have over 80pulls on my car and is is very consistant
The test consisted of 6 pulls with mobile 1 5-30 (had 200 miles on it) all of which were at 507-508rwp there was no variation greater than the 1 hp
I then switched to the German castrol 0-30 (0 miles) and all 7 pulls were 503-504 rwp no change in tuning or anything else.
To make sure that the Fresh oil was not the cause of the HP loss I then put New mobile 1 5-30 in and Made 2 pulls at 507 rwp.
The dynographs were not worth printing as they are so close that they overlap eachother. I know how these tests go without proper proof(dynocharts) so all I have to say to that is that I am not posting this for debate or for the credibility of my test to be questioned. I did this test for my own knowledge and to help me decide which oil I would run, once I found what I did I decided to share my findings and let you take it as you may. I was hoping for the thinner German to make more power and was dissapointed, but that is why I did this test.
I am sticking with the 5-30 for added protection and a few more hp.

Good data thanks for the test. I am with vettennuts. GC is thicker. So more hp loss. It has been said many times Mobil-1 is thin. U showed this very well. I will stick with GC for more protection. If u want a few more ponys go with Mabil-1.

cool Thanks for the Info on that

My dad switched to 15W-40 in his 89 Chevy 350 truck, and the motor blew one day while he was backing a trailer up the driveway. It was fine all the other times he towed, when it was running regular 10W-30. I cant help but think that had something to do with it.
If you look in the owners manual of your car, 20W-50 is even a consideration. I run Mobil 1 5W-30, which is reccommended, and I've been very happy with it. Full synthetic, like Mobil 1 or RP, offers much more protection than conventional oil, even though it may be much thinner. It clings to surfaces better, reduces friction between parts, keeps the inside of the motor cleaner, doesn't break down under high temps like regular oil, and also lasts much longer than conventional.

I've been running an MS3 or MS4 on my extreme H/C/Complete bolt-ons set-up for ~50,000 miles on a stock bottom-end LS1; I only installed the rod-bolts a few months ago.
I drive "quite spiritedly" everywhere I go at all times
EDIT: forgot to mention I've run Mobil 1 5W-30 since the Firehawk had ~500 miles on the odometer

That doesn't mean it's not wearing more by running Mobil 1. It just means it hasn't worn to the point of failure thus far. GC protects better by a long shot which has been proven time over. No one here is saying M1 is crap, it's just not as good as GC, point blank.

I honestly can't see how it can be any better in terms of wear. It may last longer due to more additives and such, but I find it hrd to believe that there would be a measureable difference in wear of a motor that runs RP and one that runs M1.
