VBdenny Posted August 7, 2003 Share Posted August 7, 2003 Just wondering what kind of gas milage people get with their LS 400's. It would be nice if you list the year so we can compare that factor as well. On my 1990, I checked in at 24.3 mpg on a 350 mile trip. I was running between 75 and 85 most of the way. I did have several stoplights on the Eastern Shore. Around town I average about 19 mpg, and I rarely "get on it." Premium Fuel is running at around $1.49 a gallon in NJ and $1.55 in VB.

thewzdoc Posted August 7, 2003 Share Posted August 7, 2003 My 1990 LS400 gets 24 MPG hwy and about 18 city (I like to accelerate!) San Diego Premium gas ranges from $1.74 to $1.90 I drive 50 miles one way to work at about 85mph on the freeway. Quote Link to comment Share on other sites More sharing options...
spiller91ls Posted August 7, 2003 Share Posted August 7, 2003 wow, some you guys need to change your driving habbits. the gas we get here in NM is unoxygenated gas and I regularly get 27.5-28 mpg city and/or highway, it doesn't seam to make a difference. the gas here is 1.78 gallon right now here. If I put gas in at Phoenix AZ, then my milage goes down to about 24.5 mpg, this is with a 91 ls with 161000 miles on it. Quote Link to comment Share on other sites More sharing options...
brentg Posted August 7, 2003 Share Posted August 7, 2003 I am in central California, we do have a additive in most fuel MTBE which is known to be cancer causing agent. I drive a 1995 LS400 and get 26.5 on the freeway and 19-20 in the city. I agree, some of you guys must have a very heavy foot. Brent Quote Link to comment Share on other sites More sharing options...
kinhoang Posted August 7, 2003 Share Posted August 7, 2003 Still lucky for you all. I live in Hawaii, my 90 LS400 get full tank for average 300 mile. It means about 13 - 14 miles per galon either on free way or city because roads here are so short in crowed. We pay $2.15/galon. Just wonder after the Iraq war, why oil company still have reason to keep jacking up the price instead of dropping it? Happy day you all.

Lexusing Posted August 7, 2003 Share Posted August 7, 2003 Currently I am getting about 18 or 19 mpg, mostly city driving (Cols. OH) on my 96 LS400. I am pretty easy on the gas when I am driving......not sure about highway tho....will get an average when I head to Toronto sometime this month... It may help if you have the correct tire pressure...I am sure you all know that.... Quote Link to comment Share on other sites More sharing options...
VMF Posted August 7, 2003 Share Posted August 7, 2003 i think i'm gettin such low mileage in the city because driving in brooklyn is a truly unique experience. so many doubple parked cars and other kinds of obstacles that it requires a lot of pushing the gas and braking. i hate drivin in brooklyn. i really rest and relax when i drive in jersey or even upstate NY. every1 is so polite and will yeld and do all other kinds of nice things. you will never get it in brooklyn. all you can get is F..k you! or smth "better":) Quote Link to comment Share on other sites More sharing options...
vyhanh Posted August 7, 2003 Share Posted August 7, 2003 $1.60 per 91 gallon here in Twin Cities. Without aircond and light footed, I get 20mpg for 91 LS400 127K Quote Link to comment Share on other sites More sharing options...
spiller91ls Posted August 7, 2003 Share Posted August 7, 2003 I actually am a very heavy footed driver, the trick is to be smooth on the gas and breaking. the only gas that I put in my ls is texaco/shell, since gas quality makes a big differance. try and avoid gas that have alcohal methanol, and ethol. one trick to find out if the gas has any of these is to put some in a bottle or glass jar, add water and shake it, if the water is absorbed and you can't tell the difference from gas to water, then you need to find a different gas supply. it also gives off reall bad vapors when you are putting gas in your tank, makes you kind of nousios.

chromiez Posted August 7, 2003 Share Posted August 7, 2003 on my 1991 ls400 i get about 250miles on a full tank. about the same with everyone else 15mpg in the city, but for me i cant really tell a difference on the highway, i think i kill more fuel on the highway.

Psst....you site driving habit sand then tell us that gas from AZ nets you mileage that is about what we get. I think it's the gas and not the style! I want to know what the hell they put in the gas in NM to net you 28 MPG on hwy or city....sounds mighty fishy to me. Quote Link to comment Share on other sites More sharing options...
LS400Convert Posted August 8, 2003 Share Posted August 8, 2003 Sounds like my experience is about the same as everyone elses. I get 19 around town and about 25 on the hwy. I always run Shell or Texaco premium fuel. Premium in Houston is running about $1.55 right now. Quote Link to comment Share on other sites More sharing options...
VMF Posted August 8, 2003 Share Posted August 8, 2003 i use mobil or BP all the time, no difference in them. should i try sunoco or smth like this? Quote Link to comment Share on other sites More sharing options...
VBdenny Posted August 8, 2003 Author Share Posted August 8, 2003 I buy my Premium at Costco when I'm in Norfolk, and at the Caldwell Gass Stop when I'm in NJ. I think gas is gas. I have read that the oxygenated gas really drops your gas milage significantly. Perhaps a 400 could get 28 MPG if you were on a long straight highway and you kept your speed below 75 but neither is gonna happen much for me. Having driven around Brooklyn many, many times, I know what VMF if talking about. Let's just say that it's much different from anywhere else. Cars are double parked, triple parked, and sometimes just left where they stop. Quote Link to comment Share on other sites More sharing options...

ToddLS400 Posted August 11, 2003 Share Posted August 11, 2003 No way he got 28mpg with this Toyota V8, 4.3. Especially if he's adding in city driving. Too much displacement. Maybe 25mpg with cruise control on, flat, no A/C, 70mph without stopping, 70 - 80 degrees outside, etc... I'm happy to get 20mpg. I usually get 15mpg. I stomp on it a lot though...hehehe Quote Link to comment Share on other sites More sharing options...
ccf913 Posted August 12, 2003 Share Posted August 12, 2003 I average about 14 mpg as well. About 240 per tank. Long trips (about 4.5 hours driving, 300 miles each way) gets me almost 400 miles per tank at about 21 mpg. Premium here in the Kansas City metro area today was $1.93. I like to floor it a lot. Most of my driving is stop and go with a 10 mile per way trek to work each day. Very little highway driving. A/C always on. I also have remote start, so the car idles a bit (to cool it down in the summer and heat it up in the winter) before I get into it. Quote Link to comment Share on other sites More sharing options...
spiller91ls Posted August 13, 2003 Share Posted August 13, 2003 I just got back from shooting a pistol match at mesa AZ. when I found some gas by my buddys house for 1.71/gallon. my trip od was as 450.8 miles and I took 17.232gallons to fill on a 22.5 gallon tank. this works out to 26.16 mpg. when I was filling the tank I noticed that it was labeled as 02 gas, had 15% methonal. I'm in the process of using up this crap gas. normally I hit 300 miles at the half empty mark. right now i'm at 330 miles and at the 3/4 empty mark. as far as driving straight roads here in NM, yes we do have very long straight road, and our speed limits are 75 mph, and i usually run 100-110 mph on them, thats why i have BFGoodrich Comp T/A ZR rated tires and us a escort solo s2 radar detector. the best part is i shoot with a lot of the NM state police. so that pretty go ticket repellant also.

jbrooksbreeden Posted August 13, 2003 Share Posted August 13, 2003 Curious. I remember the enormous flap over requiring Formula 1 cars and Indy Cars to run gas instead of methanol back in the late 50s and early 60s. The argument was that the perfoamance would suffer greatly. It didn't take long to regain the performance of 2.5 liter methanol engines on 1.5 liter gas engines, though. ;) Quote Link to comment Share on other sites More sharing options...
spiller91ls Posted September 8, 2003 Share Posted September 8, 2003 Just got in from a trip to Pheonix yesterday 9/7. Here is the milage I got. filled up the tank in Deming NM ($1.67/gal) drove to pheonix, on the way back stopped in Safford AZ($1.98) put 5 gallon exactly in tank. drove back to Deming and filled up tank $18.5 gallons, that comes out to 22.5 gallons used for trip, and the trip was 623.6 milesloneg, that works out to 27.7 MPG, most of the trip was done doing 85 mph exept for the mountains between Globe to Phoenix which I was doing about 60-70 mph.

99lsguy Posted September 8, 2003 Share Posted September 8, 2003 I have a 99 LS (55K) and drive it easy on acceleration. Live in the Kansas City Area so my city driving includes some highway - certainly a different environment than Brooklyn! Everyday driving I get 22 mpg. Only one highway trip but I did get about 27 / 28 mpg. Needless to say, I'm happy with the mileage. I'm looking to see if these numbers improve because I've: put on K&N (E2606) AIR FILTER USE 5-30 SYNTHETIC OIL USE 75-90W SYNTHETIC DIFF. OIL Was going to use synthetic tranny fluid but I change it every 10K (I'm obsessive!) and our friends at JP Imports told me at that interval the toyota T-IV is just a good. On the subject of mileage... I've noticed that the computer always gives a higher reading on the MPG than I really get. I filled up just today and the computer said "23.1 mpg" but my actual calculations of miles/gallons came up with 21.9. Do you guys have the same discrepancies? KC premium gas is at $1.65 THANKS FOR THE CLUB! Quote Link to comment Share on other sites More sharing options...
spiller91ls Posted September 8, 2003 Share Posted September 8, 2003 I also have a k&n filter and use mobil1 5w-30, and mobil1 85w90 in the rear. I purchased the car in april of this year and it had 150000 miles on it and it has 165000 miles on it right now ( I paid $6700 for it, the guy I baught it from needed a down payment for a BMW touring car, boy did he lose out, he had to pay $5500 for new transmission when it went out on his beemer in June, at which time he offered to buy the car back from me. He also told me that his wife could get no better that 18 mpg) the car is kind of a oddball but real nice in that it has cloth seats.

kbconv Posted September 9, 2003 Share Posted September 9, 2003 93 LS here in Nashville, TN. Average 19 mpg on 93 octane around town, haven't done a hwy. only trip yet. I got 22 once but maybe I calculated wrong. I leave trans. switch in power mode or whatever it says. Don't know if they screw with our gas or not. I use BP and Exxon mainly. Need to find a Chevron station, I hear there Techron additive is a very good cleaning agent. I'm getting ready to switch to Mobile 1 and other synthetics for properties and to see if it makes a mileage difference. Quote Link to comment Share on other sites More sharing options...
