Nice additive package. May run that in my drag and drive 565 when I'm not on the track using Dominator

Wait...you change Amsoil every 3,000 miles???
Dang.
Hopefully just using their cheapest OE oil and not Signature Series.

I've changed at 3k since 1970. First and last owner of all my vehicles.

Have this in my 18 Outback right now. Just passed 8000 miles on this oci. Oil consumption is down, engine is quite and smooth, hoping some piston cleaning is going on. Thinking about sampling at 10k. Also looking forward to cutting open the OG Titanium.

Hey! Did you ever do a uoa?

I did not. Switched gears and I’m currently halfway through a 4 oci test with R&P.

TBN is lower than advertised than Amsoil, just an observation.

TBN is lower than advertised than Amsoil, just an observation.

Blackstone uses D4739 method for TBN which gives a lower result due to the use of a weaker acid and less polar solvent. This is fine for used oil, but Blackstone uses it for both new and used oil. Amsoil's report is with D2896 method which uses a stronger acid and more polar solvent which gives a higher result as it's able to see more of the base present. D2896 (perchloric acid) will titrate both strong and weak base where as D4739 (hydrochloric acid) will only titrate strong base.

Methodology difference. I don't remember all the ASTM methods. There were 3.

Amsoil uses D2896.

RDY4 - like a bullet. Thanks @RDY4WAR

sure, that is why i called it out as an observation.....of the results.......not the a actual characteristic of the oil
