Brad Penn review
I thought it might be useful to some to get a "real world" update on using Brad Penn which I put in my car a couple months ago (mixed 10w30 and 20w50 to get 15w40).
We all can debate it's chemical contents versus other oils on the market until our fingers fall off (you all know the post I'm referring to!) so I won't get into that. However, I am confident that it is a solid choice if one is uncertain about the Mobile 1 currently on the market and doesn't want to sink almost $10/quart into Redline, a full synthetic, like myself. Remember, BP is a partial synthetic with only about 10% synthetic.
The difference I have noticed between BP and Mobile 1 is that the BP has run a bit hotter when the engine is pushed. During normal driving or slightly spirited jaunts, there is no difference. However, when running at fast speeds with most shifts close to redline for extended periods, it definitely runs hotter. When I say hotter, I mean 9 o'clock or a touch above. The only time the Mobile 1 reached this temp was on very hot days and sitting in a traffic jam. I am interested to see what happens in the dead of the summer.
Hope this helps and please feel free to share your experiences.
Best,
Adam

But remember, you're making extra horsepower with Brad Penn due to the whole heavier oil = less friction thing, so that might account for the higher temps.

I followed the same formula that flatsixforme used and havn't noticed a difference in temps, we have had extremely warm (95-98) weather here in the mid atlantic area and put it to the test this past weekend on a very spirited run , oil tempetures ran about the same maybe a little lower than what I have encountered in similar air temps in the past .So far I'm comfortable with the change.

Did you record ambient temps with either oil? Driving differences could aslo account for any increase in temps.
I'm not sure how a heavier oil creates less friction; I thought it was the other way around.

More heat is more friction, so less HP. The lower the oil viscosity, the more HP you get from less friction.
I just put some Amsoil Euro 5-40 in my C4, I'm getting another 3mpg, on the freeway, & it feels a lot more peppy. It has ZDDP, or what that stuff is in it.

Much like Chuck Norris, Brad Penn pays no attention to nature's troublesome laws.

I trust engineers! 
Where are they?
There are people who are fluid engineers with 4 years of undergraduate work and 3 years of PhD work, and then go on to understand fluidity in application.
Those guys and gals aren't going to work for Brad Penn. They're going to work for Exxon Mobile. For much more money. Brad Penn can't afford them, and Exxon Mobile can.
Ask any engineer. I'm all for giving the small guy some help. I love the underdog. But you simply can't out-engineer Exxon Mobile in the oil department. You might have to carefully shift through their offerings to find the equivalent of an old favorite, but you can't beat them in their pure research.

Come clean Adam.
You forgot to mention when your temp gauge hit 9 o'clock you had been running ***** to wall with a bunch of Lambos & Ferrari's.
FWIW-I am running the same BP blend as Adam and no temp differences yet. I'll do some more research
this weekend.

Mix 10 30 with 20 50 and you get 15 40?? Since when did oil go to math class? I'd like to see a sample of that sent to Blackstone Labs to see what the weight really is.
