I have had three (3) GM 3.8 liter engines and they all vary in gas mileage, why? First off, I drive 120 miles/day - same stretch of road AND I know how to check mileage - over thousands of miles driven. FIrst car was a 1992 Pontiac Bonneville with with 3.8 engine at 190,000 miles - got 27-28 mpg on highway at 70 mph. (car totalled in accident) 2nd car was a 1999 Pontiac Bonneville with 3.8 engine at 110,000 miles, got 27-29 mpg on highway at 70 mph. (engine and transmission went out, sold car) 3rd car IS a 1992 Buick Lesabre with 3.8 liter engine at 110,000 miles, I am currently getting 23 - 24 mpg on the highway at 70 mph. I have tested this over 6,000 miles and I can only get 23 - 24 mpg???? Why dones the 3rd car get the same mile per gallon? Well maintained, using the same engine oil and driving on the same road? Thanks!
