i have heard of people switching from brad penn to vr1 20w50 valvoline.
FWIW the engine gunk thread is almost 10 years old now and Brad Penn has changed their stance from what is noted in this thread. I was looking around at different oils and came across this bulletin from Brad Penn's parent company D-A Lube and they basically say that the oil is fine for e85 as long as proper long-term (winter) storage procedures are done. And this should be true of any oil anyways. The PDF is on the D-A Live site here:

Or this is a direct link to the PDF:

I know there are many threads on this. I am replying to this one pretty much just because it's the newest and I think the info can be useful to people that are questioning their oil like I was. It also contradicts points that some have been pushing on this forum for years with the 'gunk' issue and BP's recommendation at the time (2011) with revised info straight from BP that, at this time, is only 1 year old.

fp's list for oils is pretty broad i live in northern california and decided to go with the vr1 10w30. it is still on there recommended oils and is still pretty affordable. doing fp red upgrade in a few months so i started it early 
I would listen to fp. If the turbo fails for whatever reason and they do an oil analysis and determine you are running something not recommended (they have a list) they will not warranty your turbo. Consensus I've heard is that the thicker weight keeps your bearings happy especially if you run the car hard. FYI I just switched to 20w50 myself having run 10w40 mobile with 113k on the clock.
I'd rather kill a turbo.
To run 20-50 in a stock block is plane dumb in my opinion. Have I done it, yes. Was it worth it, who knows. All I can say is that the bearings in stock engines are tighter. We all know this. Looser engines are set to be looser so the crank can bend due to the high loads of the engine. 20-50 is there for that extra cushion. Stock block, stock clearance, the oil is going to have one hell of a time flowing. Meaning higher oil pressure, so on and so forth.
If I do any track days this summer, I may run it.. but definitely not in the winter and I'm on the fence for daily driving.
