Hi everyone. New to the forum. Land yacht lover. I typically drive Cadillacs and Lincolns. With fuel prices increasing I am looking at getting a comfy cruiser that is a bit more efficient on the highway than my 2004 Town Car. I am doing a lot of highway driving and at 6'2" do not want to cram into a foreign compact. That being said, I have been considering a Century. A friend I work for while in college had a 96 Century Wagon with the 3.1. Remember it being a great ride and she used to brag about getting up to 31 or 32mpg going to dog shows out of state. I am currently looking at a 1993 Century that is for sale in Jersey. It has the 3.3. Did the 3.3 come standard with the 4 speed transmission or could it be a 3 speed. I am thinking the four speed would have best fuel economy. If it could be either, is there any way to tell? Car is about 3 hours away so I was hoping to figure this out before the trip. Also, is it reasonable to expect 30 mpg on highway with this motor? Car has been garaged for life, 20k original miles. Of course I will have it gone through and tuned up. Thanks for any insight.

Look at the shift indicator if it's PRD21 it's a three speed.
If it's PPRD21 where the first P has a circle around it indicating Overdrive it is a 4 speed,
The EPA rating with the 4 speed on the highway was 26.

Maybe wishful thinking, but I felt the epa ratings for some of the Buicks I have been looking at seem low. My wife had an 88 LeSabre Coupe when we got married. It had the 3800 and we regularly got between 28 and 29 mpg with that on the highway.
