Blackstone Used Oil Analysis (UOA) Mobil 1 Extended Performance 0W-20
 

At the time of the test, car had 34500 miles overall, the oil had about 3400 miles. Engine is stock. Just throwing it out there for anyone interested in info on Mobil 1 EP.
I'll probably have UOA done every 30k miles or so, just to track the general health of the engine.

By the way, is there a compilation of all UOAs on these forums?

I also use 0-20W Mobil 1 (Advanced Fuel Economy)

Just sent Blackstone my sample at 23k miles. I am also concerned about oil consumption -- we'll see what they have to say.

With regards to oil consumption, last I checked my oil it had been over 8,000 miles since my last oil change and it was still just shy of the full mark, with ZERO oil added since that oil change. And my BRZ has 63,000 miles on it. #winning

I posted my UOA after 10k miles of Mobil1 (did not add any oil) and the results were fantastic, TBN was great as well.

I actually just switched back to this oil after running Motul 5w30 for a year or so. Wanted to go back to 0w20 and was due for a change so I just went to Walmart for supplies this time. Might shop around with Amsoil or Schaeffer's next time, but I'm glad to see this oil still suits the engine fine. I have noticed the consumption myself as well though.

I do plan on switching to 5W-20 (wife's car calls for 5W-20, so I figured it's easier to buy the same stuff for both cars).
When I used 0W-20 for both cars, her car used up more oil than usual.

Makes sense, thinner, less viscous oil burns faster.

I barely burn any oil at change time which is usually around 7k with 105k on it now. #alsowinning

Same boat as you guys, no oil burning here either. Running e85 by the way so my change intervals are 4500-5500 miles and they haven't dropped past the full mark. I've been using Eneos 0w20 off amazon.
