Having problems with your 1987 Volvo 740 ?
What is the unleaded fuel button on the volvo 740 turbo? I just got a 91 Volvo 740 turbo, and it has a button on the dash that says unleaded fuel. If i push it, it makes a weird buzzing sound. SHould I be using unleaded fuel in this car, or premium?
85 octane is all you need unless you are at sea level then use 87 octane...
