Car not getting gas when stopped at light.When I go its fine

hello! that happen to my car and after a couple of visits to the my mechanic we find out that it was the kind of gas, so now i just use the one after the regular gas or premium. after a couple day it was perfect!!! my mechanic told me that since my engine is high endurance i couldn't use regular gas. i hope this help you.

I think you misunderstood Hanna09, not "High Endurance" but rather "High Compression" and indeed it is and the owners manual does say Premium Fuel 91 Octane required for the 3.0L V6

Also, don't buy gas from convenience stores or independent retailers. Very important, the cheap gas is, well cheap gas. It does not have the detergents the Lexus needs. For a list of approved Lexus fuel see http://www.toptiergas.com/retailers.html

Ok I notice the link does not work. But you can go to http://www.toptiergas.com/

Then at the bottom click 'retailers'
