And it looks like they have all returned more or less the same results barring a few outlier elements per change in fluidThose, and:
- Pennzoil 10w30 conventional I had laying around in the garage that somebody gave me years ago.
- Mobil 1 5w30 that I drained out of my new LS3 crate engine.
- Valvoline 5w30 high mileage
- I think I also had mix of Amsoil 5w30 and leftover quart of Valvoline 5w30 at one point too.
