I've been wondering about my car. It seems that no matter how it's driven, it gets right at 30mpg. Volvo 850 5speed
I can drive it really easy on a road trip, or I can drive it around town like I stole it, and I still get the same results.
Premium fuel or regular fuel doesn't change anything either.
This is not an effort to disprove anything else on this forum -
In my other car it makes a difference by several mpg depending on how it is driven. That takes the driver out of the equation
It has always passed emmisions testing (pre- obd2 sniff test)
way under the limits.
Any ideas why it doesn't get better mileage when driven easy or on road trips?
