I just clocked a 2,123 mile trip over the last week with my 97' SC300 with 170,000+ miles on it..all stock engine. Dash reads 26.2mpg average, with average speed of 58.2mph. This was with A/C blowing and running 70-80mph on the highway which covered 1,700 miles of my trip. Now around town here at home I get 18mpg combined city/highway. But that just driving back and forth to work during the week.

ive had roughly 24mpg on my 93 sc300.... i thought i was getting around 14mpg but then i began to do the math when i would fill up instead of assuming i was empty around 18.5gal... apparently i can drive alot more before my gas light turns on

I get about 19.19 mpg with City / Highway 25 / 75. So that would be about 395 Miles Per Tank. I am using a W58 with the (Automatic) 4:27 Final Drive . Gas miles could be better. If I used the W58 with the (Manual) 4.08 Final Drive. All in all gas miles are about the same as before the engine swap because I had the same transmission Combo

OK guys i just got back from a 1000 mile trip (500 each way) and i averaged over 28.5 MPG both ways driving thru mountains in VA and NC with the A/C blasting the whole time and averaging 70 mph (usually between 70-80) the whole way using cruise control, i have no doubt if the A/C was off and i slowed down a little on flat land i could break 30MPG (indicated). My car has 165K on it and going up it was N/A and coming back its now boosted and it made NO DIFFERENCE in milage since i stayed in vacuum the whole time. I took some pics on the way back, I filled her up to the rim before i left with 93 octane and when i stopped for food etc... she said 424mi on the trip meter and i still had gas left, i have no doubt i could have gotten 500mi out of the tank if i wanted to run it down to fumes.

According to my dash I average about 21mpg, but according to my calculations (Miles driven divided by how many gallons to top off the tank) I get about 16.5-17.7 mpg on average with me driving. I've gotten a full tank of gas every time I've had to pump since I got this car. I do 75% highway and 25% city driving. If its not me driving the car averages about 20mpg mixed. The most I've ever gotten is 25 mpg all highway at 70mph with the air conditioner blasting.
This is on a 98 bone stock SC300 that has all new maintenance items already replaced. (spark plugs, fluids, filters, and the occasional seafoam treatment.)
