That is a good choice. You can also run Rotella 15w40. You want some really good stuff, Get some Joe Gibbs oil.

I have 225 hours running Valvoline Racing straight 40W in a 500EFI. This is absolutely the cleanest oil I've ever seen come out of a container.

I use Mobil 1 15W-50. Having a problem now finding it in the 5qt containers. Hear Mobil is not packaging it that way anymore. Anyone know of another synthetic that you can buy in 5qt? Walmart used to be reasonable when they had it. To pay $8/qt from an auto parts store does not make sense to me.
