How many gallons are in my 99 SVT Cobra tank...? Also should I be puttin in 91 ? or 87...what type of a difference does it make...I just got the car and I put in 91 but I forgot to ask the previous owner what he was using (the car has some engine mod's as well...exhaust, intake, headers...etc...more details in my perious post if you really care) Thanks

 

All SVT's take premium fuel.

 

My gas tank is 15.7 gallons I am almost positive a cobra has the same tank as a gt.
