I first want to start off and say if this is posted somewhere, I am sorry for reposting this question. The site would not let me search.
This said,
I recently purchased a used 2003 GS300 with 42,000 miles on it. I have been averaging 14.9 mpg - 16.9mpg. This is with 60% driving city and 40% highway. The EPA suggests 18mpg city and 25 highway. I should be averaging around 20mpg. I took my car into the Lexus Dealership where I purchased it, and they kept it for 2 days, testing it on the machines, and supposedly filled it up, drove 41 miles, and put 2 gallons back in it. Therefore getting 20.5 mpg.
During this time they loaned me a ES350 (EPA 21 city 30 highway) which I have been driving twice as aggresive as I do my own. I have been driving it 75% non aggresive but 25% aggresively flooring it, and accelerating harder than in my own and I am averaging 21.5 mpg. HOW the hell does this happen?
I traded in a 2006 350Z which has 19city and 26 highway. I drover car the same 60% city 40% highway and averaged 21-24 mpg when driving non aggressive, and 18-20mpg when driving more aggresively. When I drove it completely messing around, power sliding, racing, highway speeds at 90+ I would STILL GET 17mpg, Which is MUCH better than the GS300 getting 14.9mpg when I am driving barely aggresive. (before anyone says anything about my racing, power sliding, and 90+ highway speeds, understand this is this reason I got rid of the 350Z and got the GS300)
Has anyone else had this same issue? or Should i just accept getting crap for gas milage?
