This stuff is dark and watery. I keep forgetting its ws2 so it's gonna look dark. Reminds me of LM Mos2 but without the euro cool metal can. Added yesterday again to the Redline 0w20. It was record cold here yesterday for this time of year. Managed to save just enough 9200 to mix in some 9100 that I will use on her Toyota Tacoma. Results for winter startup aren't conclusive yet. It ran awesome this summer so I will see what all it will do this winter. Sure it will be fine.
