Fuel additives in low milage car ?

[Bill Balkie 24172]

Hello
    Recently I purchased a Cadillac with 37000 miles .i am sure the engine has never been tampered with . Should I be adding a fuel supplement to composite for the today’s  non leaded fuel ?
   
    Thank you ,
           Bill

Nope, waste of money, in my opinion. Try and buy fuel without ethanol if you can. If not use a fuel stabilizer and don't leave the fuel in the tank very long. Cars need to run and ethanol separates pretty fast. A website called "Pure Gas" has an app to find stations that sell it, as well as  some airports and marinas.  I assume you are writing about a pre-1974 car, otherwise you can't buy fuel with lead in it as some airports sell.

Hello Jim
     Thank you for the information . Not to many places around me that has that fuel . I will continue to use Sunoco 93 octane.

I use Stabil 360. One ounce for every 5 gallons at fill up.  No pure gas in my area.  My gas doesn't sit long enough to separate, but I use the additive anyway.

Even though I go through a tank of gas at least every couple of months, I use Stabil 360 as well as protection against ethanol since pure gas is not an option for me.
