yeah only 10W30 conventional here in Eastern Iowa... I was intrigued by the 5W30 synthetic blend, but to be honest the Full Synthetic 5W30 Super Tech HM I put in the Jeep last time is hard to beat. ~$15 for a 5 quart jug...My Sam’s doesn’t carry that oil that I am aware of they have Pennzoil and Mobil 1 and some diesel oils.
Just my $0.02
