2004 Discovery oil

[2004disco]

Any unfavorable reviews of Royal Purple synthetic oil? The previous owner of this 82,000 mile Discovery used only Mobil 1. When I went to purchase more now that it is due for a change, the fellow waiting on me said Mobil 1 is the worst on the market. So, I bought Royal Purple instead and will use a Wix filter.
Haven't done the oil change yet and had to get 10W30. I am in the Florida panhandle.
Any concerns?

I didn't use royal purple in my Rover, but I do use it in my Cobra replica with a SVO460 in it with zero issues.

Thanks for that! I think I will go ahead with it.
