I'd stick with 0W30 at least unless I see something miraculous of UOAs after people give it a try here, but I don't expect anything given the tech specs.
Here are the tech specs

I like the viscosity numbers for 0W30. In addition, I usually look to see if the oil is BMW LL-01 approved, which I don't see for Edge. I think it may just be some marketing with the name (it's used overseas) (though the oil is likely quite sound and still good).

I just don`t understand why my 1mz-fe uses oil on the GC,and not on the Mobil-1 0W-30,and PP.Is my RX just dopey or what? Same thing with my transaxle/transmission,it doesn`t like its own Toyota fluid or amsoil....... I don`t get it!! I will mention that it runs nicely on the GC. I don`t know what this car would do if it had a driver that was not in tune (so to speak) with it.

lexus114 I am using the GC and have no signs of useage, 3 to 4 k changes and the level stays at full. I do have seeping valve cover gaskets, but not enough to affect the level. I have a 2005 Ford F150 that never stays the same between changes, but I assume it is the crappy engine.....or poorer specs on rings, valve stem seals, etc....

I have been running GC in my girlfriend's 99 5.4 L Expedition, those things love to suck oil. Though I have used some additives (Liqui Moly Motor Oil Saver and Restore), because I suspect there is a leak in one of the cylinders, but the problem appears to have been solved.

Yea the engine runs great, but I have already lost an injector, I changed the plugs because of breakage at 28 k and put in one piece champion plugs...so far so good. I like the truck, have put in a Lincoln Mark VIII cooling fan, and a bunch of backup devices....

I used to have an issue in her truck with a misfire, but it appears to have cleared itself up after I did the oil and additives. I am sure some oil was sneaking in there.
