I think everyone is getting too caught up in the base stocks. Yes base stocks are important, but it's the combination of the base stocks with the add pack and overall performance of the oil that matters.
OP is asking about extended intervals. I'm going to add that the during the warranty period, stick to manufacturer OCI. After that, then you can look to longer OCI. ClaySlayer hit the nail on the head with UOA. It doesn't matter what oil you run, UOA has to be done to see how it is holding up. When it all comes down to it TBN is going to dictate the OCI. After warranty is up, pick the oil of your choice, do UOA, and keep driving. Until you reach the end of warranty just keep using an approved oil and keep records of it just in case.

Just had mine changed today and put in Penzoil Platinum 5w-20 with a FRAM Tough Guard filter #10575. I have no fears that my eco will blow up because I put synthetic in it, the factory stuff was jet black and nasty, glad I changed it out at 4400 miles and NOT the 7500 the dealer said I should.

Hopefully you put 5W/30 in which is what's called for, not the 5W/20 you stated.

My twin turbo direct injection BMW came from the factory with full synthetic. I feel if BMW and all the homework they do uses it in that application we should be fine on the EB.

my first oil change will be due here in about 2500 miles. i was thinking of putting royal purple in her. any suggestions?

Dump that 5w-20 and replace it with 5w-30. Also FRAM is the worst filter out there.

Is it API certified and the correct GF standard? If it meets the ratings you can go for it, but IMO it's overpriced for the Group blend and the additive package.

i dont know, im using this site for a learning tool. i guess i will have to do some outside research. yes it is pricey but this is my first brand new truck and wanted to get the most out of it.

IM sure there is nothing wrong with Amsoil I have used there gear lube with great success but to the best of my knowledge Amsoil moter oil is not API certified for gasoline engines and therefor could void your warrenty even if changed at the recomended intervals. As per Ford owners manual. Just a thought
