My latest mod,CNG Fuel system,with gas going crazy i bite the bullet an had a CNG [compressed natural gas] system installed.
In utah cng is widely available,an at 1.04 a gallon locked in for the next 4 years, through Questar [our gas co.] i will save about $2500 year based on 15000 miles a year, at $3.50 a gallon.
every dollar over 3.50 is another $1000 a year saved
yes, it is very expensive to install ,about 2 years to recover cost at $3.50 a gallon,if it hits $5.00 [an it will]little over a year to recover cost.
as i only have 18000 miles on my truck, i see a huge saveing in the future
i have a 11.4 gallon tank in back ,so depending on driving conditions i have around a 180 mile range on cng ,plus the regular tank [if i want to run it]
