i am mid oil change on my 08 taco 4.0L.
i got some Valvoline full synthetic 5w-30 in a 5 qt jug and its not quite enough. they only had 5w-20 in the same oil in quarts. is it ok to put that in with the 5w30 i already put in or should i go try to find some more 5w30 somewhere else? i am leaving for a 1000 mile round trip vaca in a few hours.
