Royal Purple after 100k?

I used to work at a research facility in the chemical engineering dept, specifically fuels and lubricants. We used to test lubricity and longevity of oils and the deposits they leave behind. No synthetic oil did really any better than any other in any of the tests. They all created the same wear over the test time, left the same amount of deposits etc.
We didnt test any specialty oils, just off the shelf oils like mobil 1, RP, Castrol and so on. So hopefully some of you can see how I formed my opinion.

i run royal purple in my 08 from the first oil change..now has 52000 miles..have ran it 15000 miles before... and it still looked good(that doesnt mean anything tho)...with K&N filter
in my 02 its had scheffers syn... from about 60000 miles its got like 145 now...my dad runs it between 12 and 15k usually... with a motocraft filter or K&N filter
i think a good choice to use is what has always been ran in it... after running 90k on 1 oil...i would not change it up...

Me too! I just got my oil report back from Blackstone and will get it posted up here soon. They said everything looked good except for a larger amount of iron and aluminium, which I think was caused by excessive cold starts in below freezing weather.

But, Synthetics DO act the same as blends and regular dino oil, they just last longer.

I've heard its not great to jump between brands, but I ran RP for the first 70 000kms and when it was getting scarce up here in the frozen north I switched to Mobil 1 Full Syn. Seems to be good so far. Personally I wouldn't run anything but full syn in my truck.
