The 4 cyl,s of today are geared to run higher rpm at cruise speed simply because of stiffer emissions standards. They aren't clean enough when they are "lugging" at 1500 rpm at 55 mph like the older ones and like the 3.8 v-6. Any engine that is turning 2200 rpm at 55 is not gonna get 30 mpg! The 3.8 in the said Buick etc is between 1700 and 1800 rpm at 55 and not even working the injectors at that. Sometimes high mpg doesn't equal clean air (according to epa.s formula anyway)In my book if ya burn less gas then the air is cleaner,period! And to top it all off , the 3.8 was an OLD tech pushrod cast iron block that wasn't supposed to out perform the 22 overhead cam 50 valve high rpm all alum. buzz engines that they WANTED us to buy. Guess the joke was on them,eh?
