I agree with TNS. Great oil placed just below the YB in the SOPUS lineup. Buy all you can while its still cheap. Once Walmart detects a run on it they will raise the price.
I'm using it ( 5w30 )in my 01 Durango V-8 and so far have seen good results. I'm no scientist at all but it does appear my truck likes it. The price is lower than Mobil 1 and comparable oils on the market so the "Q" may be a sleeper but it's appears to be a fine oil.
