i usually take my all original 89 vert. out 1 to two times a week. i average 15 to 30 miles a trip, average speed 30 to 90 miles an hour. average gas mileage shows 20.5 to 21 mpg. yours seems extremly low. start with gas filter, then plugs, perhaps air filter,lagasvd said:1986 convertible, stock with exception of exhuast, I get consistent 29 mpg on the highway and 19 mpg city if I take it easy.
