Hi,
I bought my ls 2 weeks ago and I notice I have huge fuel consumption. I do mostly city driving 7 miles one way and back. When I drive normal under speed limits and without crazy accelerations I get only 12mpg. I try for last 2 days drive extremely smooth and slow with minimal gas usage and everywhere I can with cruise control ON and I only get 15-16mpg but is nearly impossible and unsafe to driving like that all the time. I read a forum members mpg reports for ls460 and average for normal city driving is 18-20mpg. I check my air filters and they are clean , also I do not have any fault codes on the dash. Can anyone let me know if my mpg is normal or if not point me where I should to look for problems to sort it out fuel economy. Regards Lucas
