Not a problem as long as you don't hammer it, but your mpg's will be worse as it will try to make up for the lower octane by reducing efficiency. Why would anyone who's driving a V not feed it what it deserves?
You're right. Nothing wrong with being frugal. Being frugal is what helped many of us to acquire our V's.it seems to me to be a total waste of money to use premium gas when you're on cruise control at 75 mph. THere's a difference between scrimping and being frugal. I've never put anything in it but premium, but it's never been on a long trip like this either.
You and your logic and your math and your common sense!You're right. Nothing wrong with being frugal. Being frugal is what helped many of us to acquire our V's.
Having said that, I doubt it will cause any damage to your V. It will at least rob power though.
Figuring the round trip from Tampa to Knoxville is about 1,500 miles, at 20 mpg it should take about 75 gallons of gas. With a savings of fifty cents per gallon you keep about $37.50 in your pocket.
For that amount of savings I'd go with premium and keep all 556 horses kicking.
Yes, at the expense of power and mileage. If you have a high compression engine and are experiencing detonation, you need higher octane (and that's the only time)The computer will retard the timing if it hears detonation. No harm done. You can even alternate from regular to premium fuel. I do this with my Hemi. Never heard detonation. You can be sure the engineers planned for this, as they don't want to be replacing motors every time someone can't find premium fuel.
I do not believe MPG will drop with lower octane. In fact, MPG drops 25% with Ethanol, which is much higher octane.Yes, at the expense of power and mileage. If you have a high compression engine and are experiencing detonation, you need higher octane (and that's the only time)
And some of it you'll never hear. Gotta love knock sensors!the blur said:Never heard detonation.
Mpg drops with ethanol for a whole different reason. Ethanol does not hold the same amount of hydrocarbons for a given volume. Thus you need more of it to burn for a given fuel/air combustion cycle. This is true of regular vs premium also. Thus the confusion of why premium results in a bit better mpg over regular and even more so over E85. Bringing Octane into the discussion to compare mpg just confuses the matter. Octane can be better discussed as the higher the octane the higher the stability the fuel has and therefore the more pressure the fuel can take before detonation prior to the addition of spark. Thus some tend to say high test or when speeking of race fuel burning colder.I do not believe MPG will drop with lower octane. In fact, MPG drops 25% with Ethanol, which is much higher octane.
