I don't know if I can "mentally" go 15K between changes, but if the oil analysis at 11K in the OP was good, I think I'll try the 10K interval with M1 EP and a M1 filter. (BTW, AutoZone's got a promotion going on in August: 5 qt. M1 + M1 filter for $29.99....slightly more for EP, but I can't remember exact price)
Anyone know the results in the original post? Thanks.

Welcome and look at used oil analysis, they have several with the 4.7 Toyota engine, it will go 10K+ miles with the regular Mobil 1 synthetic. The 4.7 engine is very easy on oil. Don't worry.
