Drained factory fill around 3,000 miles. Went to Valvoline synthetic 5w20. I havr 2,000 miles on the oil so far. I am leaving monday on a 4,000 mile round trip from northern Michigan to souther Florida. Do you all think the valvoline synthetic will do well or should I change it out before i leave? Thanks for the help,it seems valvoline synthetic is not popular around here. Thanks everyone
