Bad fuel economy on 86 Toyota any ideas

[toyotasrule]

Hello I have a 86 4x4 on 32 1250 15 -- body lift. I have owned this truck for about 3 years. And I has never gotten good gas millage. I just did a minor tune up plugs wires cap rotor coil. I am getting about 150-170 per tank. I have been reading that It should be around 270. Is there something else I should be looking into ? Or is this normal. I drive to and from work about 6 miles a day normal driving and have been running chevron plus. Thank you for any input. And please if I am leaving info out let me know. Truck 86 4 cyl 22 re
