The Endurance is rated for 25,000 miles ... no need to change it out at 5,000 miles if you're doing 10K OCIs.
I wasn’t sure if I should dump the filter early using the Amsoil for the first time - keep hearing how the first use can possibly catch some carbon in the filter. I’m planning on a 15,000 interval overall...figured I’d change the filter out at 7,500 miles, but maybe I’ll leave it in the whole way.
How dirty do you think your engine is? Is it visibly dirty when looking down the oil fill cap hole at the top of the head? If you are really afraid it's going to over-load even an Endurance. then guess it's better to be safe.
Tough to tell, the engine has a PCV baffle system right at the fill hole, but that baffle is spotless (and I’ve seen others that’s aren’t). I’ve run three 10,000 mile intervals previously, and one 8,000 mile interval. Prior to that all 5,000 mile intervals. Just recently cut open my oil filter (from my recent 10,000 mile interval), that thing looked spotless. I’ll keep an eye on things this interval, if the oil starts getting dark very quickly I may consider changing it out, usually the color change is pretty linear throughout my intervals, all the way to 10,000...with zero consumption.
Curious minds would like to know what did that great little Toyota OIC cost?
the oil change with suspiciously high waste disposal fee was ~$86
If they did a brake inspection and the rest, that ain't bad.
Finish your Mobil-1.... then finish your existing Amsoil.I'm on the fence about what to do for next change. Continue with Mobil 1 EP 5w30 (will be 3rd consecutive run), or use the existing Amsoil SS 5w30 I have on hand or try HPL.
