What is the size of the gas tank in my 90 awd(16 gallons???)I dont have the owners manul and the haynes manual does not have this listed! Please help im trying to do the ratio for some octane booster and im getting pissed that this information is hard for me to find!!!
ALL DSMs have the same 16-gallon capacity. Different sources will fudge .1 gallon or so, and it's yet to be determined what the useable capacity is.

Now I just fill up at half a tank, which helps keep water vapor out.
