I obviously have waaaaay too much time on my hands.
Is my math correct?
You can have an increase of 3mpg in one month -
all you have to do is find cheaper gas than you bought last month..
If the cost of gas increases from $1.60/gal to $2.20/gal
what is the equivalent loss in MPG? Is almost 3mpg correct?
[as the price of gas increases it's the same as if you get lower mpg]
---------------------------------------------------------------------------------
If you use premium @ $2.30/gal vs regular @ $2.00/gal
the cost difference per yr is $300 (assuming 12,000 mi per year)
The cost of replacing turbo is ????
It looks like premium gas at a premium price is cheap insurance.
-----IS this correct?-------or should I get back to drinkin beer ---------
-------------and watching 'gilligans island' reruns ----------
assuming your mileage is 20MPG and only the cost of gas changes:
at $1.60 per gal @20mpg = 12.00mpg
at $ 1.70 per gal @ 20mpg = 11.76mpg (a loss of .24mpg)
at $ 1.90 per gal @ 20mpg= 10.53mpg (a loss of 1.47mpg)
at $ 2.00 per gal @20mpg= 10 mpg (a loss of 2 mpg)
at $ 2.10 per gal@ 20mpg= 9.54 mpg ( a loss of 2.46 mpg)
at $ 2.20 per gal@ 20mpg= 9.09 mpg ( loss of 2.91mpg)
==================================================
if you travel 12,000 mi per yr, gas is $2.00 per gall = $2,000 yr
if you travel 12,000 mi per yr, gas is $2.30 per gall = $2,300 yr
________________________________________________
difference between using regular and premium is = $300 /year
