My 89 2.9 4x4 with 31x10.50 tires is a pig! I can go 180 miles driving real nice and no wheeling on 14.3 ish gallons! I took a ride in my buddy's Subaru loyal with a 1.8 opposed 4 motor and it throws you into the seat compared to my 2.9 ranger.... I was getting 120 miles to 14.5 gallons before I removed the cats. I drive nice too but I kinda have to drive hard to get up to speed or people tail gate me and I don't blame them. So far my truck has has new plugs, wires, cap & rotor, fuel filter, air filter, delo 15w40 oil & wix filter. My exhaust system is just a glass pack and a tip out the side so no restrictions or anything and I'm running a 2.5 inch system. I also installed a electric fan but have yet to see what it helps as I haven't had to fill up yet since the install. Another thing is at like 3500 rpm I feel what I like to call the "boost" kick in and it goes better I'm assuming that's the timing advance kicking in and it is more noticeable when its still not up to temp but warmed up enough to get on it (I'm nice to my truck when she's cold). Can I advance the timing to 12 degrees and have that help? Is it just my tires sucking my gas? I also do allot of short trips I rarely go on long rides in my truck. My average trip is probably like 3-5 miles if that don't help
