Apart from the EP oils, how do we know that any other 0w20 would not be in the same position after 5k miles of short trips with the fuel dilution?
This is where I stand on this oil and I knew we all had to get a UOA snapshot of it.
Background is, I went in for a brake fluid flush and a tire rotation to my indy mechanic. I came out with with the flush and an oil change. I went right back in, told them of the mistake, and got a very quick and free tire rotation. I actually made out better in the deal than if the proper services were done. The one downside is that M1 0w20 was dumped out after 2k and I degraded to a Valvoline filter from a Fram Ultra.
If I had a proper garage and all the tools/knowledge AND the time, I would be my own mechanic.
