Elimination of stock that is.
I have run M1 5w20 and 5w30 in my Mustang GT with little difference. It has 76000 miles. I went to Walmart this morning to buy either M1 0w30 or 5w20, I hadn't made up my mind. There was 2 qts of 0w30, plenty of 5w30,no 5w20 and a full shelf of 0w20 AFE which I ended up buying.
Did the change and can't notice any difference. I ran the GT hard and all is fine there too. Seems like a great selection so far.
