Was in the local Wal-Mart last night and as usual I took a walk through automotive to see if there was anything I couldn't live without. The Rotella synthetic was 12.98 a gallon. IIRC, when it came out a few months ago it was around 18.00 a gallon. Have they dropped the price or am I mistaken about the original price? Just curious, but I wonder if they realized at 18-19 bucks a gallon they could not compete with Mobil delvac 1?
