about once a year i do a used oil analysis for kicks and to see how the engine is doing, and just got this recent one back. with the fairly aggressive driving and severe heat the car gets put through down here in GA, i opt for the heavier side of oils with a good High Temp High Shear rating which also seem to help with the mild oil comsumption that this older engine shows. so, i did this run of Mobil1 0W-40 that i got on sale thanks to DJ's head's-up on a Mobil promotion at Wally World last year, and it seemed like a fair chance to drive this oil change interval out past my usual 6k mile comfort zone and see what it had to offer.



very pleased overall. an easy 10k mile oil change next time. really stout TBN which means the additive pack has tons of life left, and the cSt Viscosity is also bein a boss so its holding the 40W grade very well. this is considered one of Mobil's best widely available oils and i can see why. also cool to see silicon so low, which means the air filter is doing its job despite the dust and pollen down here.
