TWINTURBO619 Posted May 5, 2004 Share Posted May 5, 2004 what is it if the engine is bone stock? lets see, i fill my tank about what... 14- 16 gallons... and i've gotten around 330 miles out of my car on a full tank. so that's about 20 miles per gallon. not too bad for a supra engine and a car that weight over two tons Quote Link to comment Share on other sites More sharing options...

Magata Posted May 6, 2004 Share Posted May 6, 2004 I get 23 to 24 mpg driving on country roads, not freeways. My daily driving is in the Sierra Nevada foothills so I can gain or decrease in elevation about 1,500 feet. I get about 19 mpg up hill and 26 downhill.

doublesharp Posted May 10, 2004 Share Posted May 10, 2004 GS 400. On 100% interstate driving I got 27.4 mpg using 93 octane on a flat stretch thru Georgia running 75-80 mph. Get 22mpg on mixed city/hwy. Just did 1000 mile trip from S Fl to S Indiana and got 26mpg for trip. Quote Link to comment Share on other sites More sharing options...
denvergs300 Posted November 21, 2004 Share Posted November 21, 2004 On my 93' GS 300, I get about 20 MPG city/hwy. It's mostly city bumper-to-bumper driving. I've been spoiled w/t 24 MPG city/hwy on my G20, but for this kind of car seems reasonable. Quote Link to comment Share on other sites More sharing options...

RomyCHA Posted April 6, 2006 Share Posted April 6, 2006 I'm getting between 21, if I have been mashing on the throttle, and 24, if I am being a little conservative. This is on 93 octane. For some reason, I seem to get a little better mileage with the a/c on... or it could just be my imagination. Quote Link to comment Share on other sites More sharing options...
Fidel Castrol Posted April 6, 2006 Share Posted April 6, 2006 '94 GS 300: I average about 17 mpg around town, stop-and-go which is 90% of my driving. The A/C is on, and I'm usually making short, less than 5 mile trips. But with pure highway driving, I've achieved about 26-29 mpg. The best is I've averaged is high as 31-32 mpg on a tank: Almost no A/C; cool 65-degree day, back roads in which you couldn't go much above 75 mph, averaging 55 or so.

Wicked_Lex Posted April 9, 2006 Share Posted April 9, 2006 When you say 20 MPG are you talking city driving, highway, or combined? I have a GS400 and I get about 25 on the highway and 16-17 around town, unless I'm puting my foot into it, which happens quite often :) the 300 should get better mileage but not a lot more, maybe 2-3 MPG better. Unless the car hasn't been tuned lately, the most critical factor determining MPG is the way someone drives. Fast starts/stops and driving in power mode burns more gas. If you use a synthetic oil, keep pressure in tires around 35 LB, and coast more you should get better mileage. Quote Link to comment Share on other sites More sharing options...
