Mobile1 is better than RP? All the comparisons I've seen show Royal Purple have about a 4 degree drop in temp compared to Mobile1. I emailed RP about when I should change it, and how often I should change my oil filter, here's what they said
We recommend following Toyota’s recommended oil change intervals until you are out of warranty. If you were to extend the drains beyond the factory’s recommendations, they can void your warranty. Once you are out of warranty, we recommend 12,000 – 15,000 miles with a filter change at 3,000 - 5,000 miles.
The K&N filter is a great choice for your FJ.

I guess I just can't see the point of RUNNING the risk of using any type of oil out there for 10k, to 15k, even that "weird" Mobile1 oil that says 20k+ miles (Extended Performance). To me it's just not worth the risk of having oil that could not be lubricating properly in there for THAT long of an extended time.... I mean who knows the quality of the oil at 10k? Each to their own I guess. I think the max I'd go is 8k.
