have a 1999 caravan 4 cylinder-always used the lowest price gas -think it
is 89 octane--been running a little rough-friend-who is a knowledgeable car
guy said move up in octane to 91 and use the middle grade-will cost a $3
extra per fill up but will add many miles to you van...I don't know if it
will add miles but my van runs GREAT now... van has 107,000
