My first UOA on this vehicle since we've owned if over the past two years. We purchased it with 110k miles and it's been on a diet of Valvoline MaxLife Blend with 5k OCIs up until this fill. I took over the maintenance and have an interest in hitting 10k OCIs due to the driving style. It's a 95/5 highway trucklet so minus the harsh Ohio winters I think it should be up to the task.
Here are the results of Mobil 1 AFE 0w20 with a M1 EP filter after an unseasonably warm winter. Blackstone picked out the high sodium content but I don't believe it's a coolant leak since it's been on Valvoline Maxlife up until this fill which contains well over 400ppm in the VOA, coupled with the fact that it's not using any coolant. There are 138k miles on the engine at the time of this drain.
Overall I'm happy with the numbers here. I've got it on PPPP + Puralator BOSS now and I'll compare results at 8500k OCI. It won't be apples to apples but if things still look good I'm shooting for 10k.
