Like PR said switch away, but get some information there are options,including High milage oils for motors with high mile wear, I don't know your vehicle but 95,000 is not what I would call high miles for a FJ.
Good info,but, it does sound painful....reading wise that is.I've read so many oil debates on motorcycle forums it's crazy. I presume by, "reading up",your referring to somewhere on this forum?. In my motorcycles,I prefer Amsoil.
BOING! then just order Amsoil for your FJ. I personally use the XL series with OEM filters, but if you do extended OCI`s then use the Signature series.
I`m also using the Interceptor in the 2 smokes! have been for years...:rocker:
use the latest grade oil "s n" and you'll be good. from the info and classes on oils, synthetic oil is still oil that they have modified in too a molecule that in non syn. oil that does not hold up is taken out, that is why oil last longer these days but I would not go much longer than 4000 miles with synthetic either it is still "s n " grade oil and with all the valves , oil solenoids, cam adjusters and places for old oil to hide and cause problems when it gets crusty. why would you test it . also the reason for longer oil change is suppose to keep the factory from having to change cat converters under warranty..ex. chevy and dexos oil every 5000 mi. stuff I have got some inside info on.. save a cat or your engine.. what would you do?

the problem I see is when people going manufacture recommended oil change intervals is they don't check the oil and top off, and they don't realize the engine will use oil even when in perfect working order. pistons are lubricated by oil!! some is going to burn away.
m1 and Castrol bs also, today if it is s/n grade oil it is synthetic.. the whole titanium additive and others I'm not sold on yet..
