Here is the only other oil that I've sent to blackstone and another lab at the same time recently, it was a UOA though. It was from an airplane engine with the drain samples taken within a few second of each other from the same stream out of a warm engine. The other lab only tests for wear...

I was wondering what BobIsTheOilGuy members thought about this UOA methodology from Lake Speed Jr's live stream yesterday. Does this seem like a sound method? I think it does. Does anyone know how to calculate a total wear metals per 1000 miles statistic from a blackstone UOA? Do you just add...

Thank you, that is very interesting!

Thanks for taking a look: Just so I know what to watch for, which part of this VOA would be failing to meet spec? I couldn't really figure out from a few minutes of casual searching what the requirements (if any) for Zinc and Phosphorus were other than Phosphorus being capped at 800 ppm by API...

I may consider a similar pivot in the future given that M1 AFE 0W-30 in my 2500 mi analysis was down to a XXw-20 viscosity, but I have a 6000 mile analysis at Speed Diagnostix as well as another VOA from them that I will look at before deciding, and even then have a few more jugs of the AFE that...

I purchased this oil from Amazon in mid-2024 for $24 per 5 quarts. Here is a 3 year old (2021) VOA of this oil: https://bobistheoilguy.com/forums/threads/m1-0w30-advanced-fuel-economy-api-sp-voa.343621/ Starting TBN and viscosity are a little bit higher 3 years ago, maybe it's all within the...

Cryptic, care to expound? I guess I should've just not posted this analysis and waited for the results from the other lab.

Yes and I’ve switched to speed diagnostix for subsequent analyses of this oil and will post the results here when I receive them. I’m simply looking for advice based on the results here if I should switch to a different oil or not, and if so which one? Maybe I can’t know until I get the GC...

Do you know the date of this VOA? I have been reading that the formulation of the M1 AFE 0w30 has changed several times over the last ~ 5 years.

Mobil 1 Advanced Fuel Economy 0W-30 (owners manual/Ford WSS-M2C963-A1 spec compliant): (yes, flame suit on for using blackstone....I'm new here) Obviously it's blackstone analysis of M1 AFE 0W-30 at 2578 miles on a 2.7L ecoboost in a Ford Bronco, 3000 miles total on the engine (did a 500...

I've been using the mobil 1 Advanced fuel economy 0w-30 in my 2.7L ford ecoboost turbo and am kind of bummed to find out this oil doesn't seem to be well regarded since it is apparently a group III GTL base mostly. I live in a cold climate (Alaska) and during winter end up doing quite a few...
