I noticed today that my Wal-Mart has Castrol Edge Full Synthetic in 5W-20, and it also meets the MS-6395 Chrysler spec. So I was thinking of switching to it. Are any of you guys running this stuff? And what do you think of it
When I did my last OC on my super Hi Po Ford 2 liter, I had the same issue with my current oil choice being out of stock I was running the, then excellent, Valvoline Advanced and WM was out of the stuff. There was a load of Edge Black bottle. I had used that ages ago in a DOHC Suzuki Aerio 2.3 litre stick car - an affordable hot wagon back in the mid nineties. Worse stuff I ever ran, harsh, noisy, no power - like I put used parts washer fluid into the crankcase.
I said to myself, "this has been reformulated probably 5 times since then so give the sloppy Brits a shot again.
Installed it in the Ford . Same thing Terrible, noisy engine at RPM, harsh. nasty. I did a UOA on that sump also and posted it, but the engine was wearing in and was coming off a bad tank of gasoline a a few week prior to that oil install.
I say give it a shot to and tell us if you think its
the worst stuff ever. Though I guess you are discussing Edge gold Bottle.

post script:
I Have Quaker State Full Synthetic 10w30 in there now, and it is phenomenal. Highly recommend. It must be the Shell GTL synthetic alkane - or something - as its advertised pour point is well below negative 50 Celsius.
I have never like the lighter Pennzoil Platinum at all when I ran that in 20 grade a few times on various engines
My car calls for a 20 but runs much better on THIS QS 30.
