one30boy 0 Posted December 22, 2003 Report Share Posted December 22, 2003 I was wondering those with gs 400 how many miles per gallon do you guys get? Quote Link to post Share on other sites
bennynjets 0 Posted December 22, 2003 Report Share Posted December 22, 2003 I just got 30 mpg on a mixed city /hwy roadtrip. Quote Link to post Share on other sites
mejaz 0 Posted December 22, 2003 Report Share Posted December 22, 2003 30mpg!!! I would love to get anywhere close to that just on HWY! I am getting anywhere from 15.5 - 17.5mpg in city; 24 mpg on HWY on my 99 GS400 using Mobil 93 gas Quote Link to post Share on other sites
JPI 1 Posted December 22, 2003 Report Share Posted December 22, 2003 There is no way you are getting 30 mpg. 15 mpg does seem about right. www.jpimportz.org Quote Link to post Share on other sites
PLinventor 0 Posted July 13, 2004 Report Share Posted July 13, 2004 I have a 98 GS400, 90M plus miles, just took a trip, 2,600 miles and recorded an average of 25.6 mpg combined. Air running the whole way, through north eastern cities and mountains. The last 969.4 miles, all hwy, I averaged 29.0 mpgs. But on an average, I keep all gas receipts and record miles driven, it looks to be in the range of 26 - 29 mpgs, seen nothing less than 25 mpgs range yet, usually when I am getting into it a lot. Of course this all depends upon filling tank exactly or close too each time. Quote Link to post Share on other sites
S2KDDS 0 Posted July 13, 2004 Report Share Posted July 13, 2004 Alot of hwy driving, maybe 25. Normally around 20 combined city and hwy. Never got close to 30 mpg. Quote Link to post Share on other sites
JellyBean 0 Posted July 14, 2004 Report Share Posted July 14, 2004 Around 20 in the city with a light foot, and around 23-25 on the highway with cruise at 75-80. 30MPG is an exaggeration. Quote Link to post Share on other sites
