hey guys. i'm just wondering what type of MPG you guys have on your ES.. i tested mine.. i only have 22 Mile per gallon on Highway. wow. that really sucks. any ideas on impoving my MPG on a 93 es300??..

Im getting around 19.5 in the city. I havent taken it out on the highway yet. Its still a project car.
I think its gonna improve to over 20 since I changed plugs, put fuel injector cleaner in and Im gonna experiment with better gas.

13.5 mpg city. its horrble. i get around 180 miles to almost 16 gallons of gas.

i get about 23mpg or so
thats about 70% highway
with gas prices the way they are i wish it was better
haha

Lexus should reli start thinking about creating a hybrid ES. Although the new ES' have pretty good milarge anyways, but it could always be better. How much do most of you put into a full tank of gas?

I checked a few weeks ago and found that I get 25 mpg on nearly 100% highway driving. This is on a "new" engine with under 20K miles in my 130K+ 1994 ES300. I drive a little quick, but at a steady 75 mph, don't think I'd do a lot better with the mileage at a slower speed so that's that.

thats my problem, these cars need 5 speed autos. at 70mph, im cruising at 3150 RPM. thats crazy. kick it up to 80, and im doing about 3500. my concorde cruises at freaking 1800 at 70...IIRC

I just checked and I get about 22-24mpg and I spend about $37 for a full tank of gas and I almost always use Premium.

does the different type of gas really matter?? i mean i see there's 87 89 90 and they are a few cent different with eachother.. would better gas give better millage?? i am not so sure.. but if it does give getter millage i'll go for it , hearing that better gas also better on your engine..

the manual says premium, use it as much as possible even if it is 2.50 a gallon.

18.9 mpg all highway driving

There has been HEAVY discussion with regard to the use of regular vs. premium fuel, but I'll give you my 2 cents: It makes no difference with the fuel economy of your car if you fill up with regular or premium fuel. I tried that long time ago, and I get the same mileage out of both types. To me, it's all part of a marketing scheme to get customers to fork over a few extra bucks for the same kind of fuel

You really only need to use premium unleaded fuel for high compression engines. General rule of thumb is 10:1 or greater. Higher compression motors benefit from the extra octane.

For a 93 ES300, it used a cast iron block 3VZ-FE 3.0L V6 that only had a 9.5:1 c/r. Unless you're pinging (which you shouldn't with a properly maintained engine), 87 octane is perfectly fine. If you have a 1MZ-FE V6 aluminum block 3.0L the c/r is 10.5:1 with a 2 bank knock sensor system. It's imperative to use premium in that motor (although you can get away using 87 octane with no problem since the knock sensors will advance/retard timing when knock is sensed) since there is more chances of knock/ping.

I get 20-21 city, 25-26 hwy runnung 89 octane in my 98 ES300

Lexusk8 is right about mileage figures using premium or regular, there wont be a difference. You actually get better mileage with lower octane fuels, especially in higher elevations.
