V6 Fuel Pig
By Buick Man on
2007 Buick Lucerne CXL V6 4dr Sedan (3.8L 6cyl 4A)
Sometimes it feels like the only way I could get the gas mileage to be better is if I pushed it with the engine off! I cannot get this over 21mpg I am not an aggressive driver. I set the cruise between 65 and 70 yet still the avg MPG never goes above 21 on the highway, Sometimes I feel that I should have bought the V8, at least I would have had some power with my cruddy gas mileage (or I may have even gotten better mileage with the V8). Why did GM kill the 3.8? 2000 LeSabre had 15 more hp, better torque and 33mpg on the highway. What/why did they change it?
