Went to the shop today to buy a Baldwin filter (B329) for my 392. While I was there I asked if they had any 0W-40 in stock. The owner called Schaeffer's directly to ask about it and he said it was just newly introduced into their line. Apparently the owner had recently purchased a Challenger and didn't have an oil which met it's spec, so............now there is!lol! It's my preferred oil and the only oil my engine builder fills his engines with(along with the Baldwin filters) regardless of make/model/displacement. I've always had good results with it as well...
