is it so?
tnx.
No reason to use premium in a car that doesn't need it, in most cases it only contains a marginal amount more detergent than regular gas. With premium being as much as $1 more per gallon than regular, I'd skip putting premium in the tank, for as much extra as you pay for a tank of premium you could run buy a second bottle of fuel system cleaner.
I wouldn't pay $1.00 more for 93 octane Shell, but I would pay 65 cents more, as I just did buy 13 gallons one hour ago. My vehicles run better on it, versus 87 octane.
My lawnmowers and gas blower and snow blower too.
I use a 20oz bottle of Techron Concentrate every 4K, two fill-ups prior to oil change.
