brought my snowbird 2014 yaris for its usual 3500 mile, $20 oil change to my favorite superior tire franchise, expecting kendall gt1 semisynthetic again. price is up to $22, but includes free tire rotation, battery test and brake check. all ok except that valvoline replaced kendall on the menu. i'm not really worried except that $20 kendall was a great deal imho. what is bitgoers' consensus on $22 valvoline? thanks.
