Drove out to Arizona today...365 miles..

Cruise control the whole way with 3 stops.

28.6 MPG averaging 74 miles per hour.

At one point before the stops I was averaging over 30.5 MPG.

If you don't own a GS 430 the MPG probably sounds terrible...

However,

For us proud few, this is unfortunatley gives us a little hope...

I have always thought of myself as a pretty smooth driver but the Cruise Control on this car really made a huge difference in MPG.

 

WOw, thats very good for the 430 engine.

 

then, the gs350 mileage will be much better. 30+
not bad, considering that some people say the mileage is poor

 

wow! congrats!

 

On my GS350, we went to visit my friends in Oklahoma City, which is about 200 miles away.

From Dallas to Oklahoma City, I was crusing around 80 MPH, got average around 28 MPG.

One the way back, I was crusing around 130 MPH, got average around 25 MPG.

Not bad averages for a toy only had about 800 miles on it, when we took the road trip.

 

My gs300 with avg.speed 80mph did an avg.of 29mpg from phoenix to burbank.The 6 speed keeps rpm's down even at 100mph

 

That is great mileage for a V8... impressive.

 

Impressive MPG!

130 MPH on a car with 800 miles?!

 

This is by far the best MPG I have got. Usually on this trip I will average 25 ish so 28 is a nice jump..

For the record:

I made this my test run to see how good the MPG could get so at all stops I was basically coasting, running stopsigns (in the middle of nowhere) or using minimal gas to get to a restaurant, station, etc...

I am determined to average 30 MPG for a whole trip but unless I go 60 the whole way I do not see it happening...I usuall drive 80 on the highways so I am assuming that hurts a bit...

The other problem is much of the Phoenix drive is somewhat downhill

 

Good show
