2019 Subaru Crosstrek Limited
Okay, just letting you know, I don’t know anything will change. But let us know!That is what I tried later on the usual spots it was present. Not easy to reproduce. I am going to test LSPI theory, as my oil change is only 200 miles away. Will use SN Plus certified oil (Valvoline 0w20) to see it makes any difference.
