Yes, you can use 89 octane gas in your 2004 Lexus GX470, as it is designed to run on regular unleaded fuel with an octane rating of 87. However, using higher octane fuel may provide slight improvements in performance and efficiency, particularly under heavy loads or in high temperatures. It's always best to consult your owner's manual for specific fuel recommendations. Regularly using higher octane fuel than necessary is generally not required and may not offer significant benefits.
on a 2005 Lexus GX470 milages is 15MPG city and at the most 20MPG highway.
Use 91 octane or higher octane rating premium gas for the 2009 Lexus RX350
at least 91 octane
Premium, 91 or higher
no, you can not. Only gas that you should use is unleaded I think he meant 87 octane. You can absolutly use 87 octane in the tank but you may not get the same performance or gas mileage. It will not harm the engine or fuel system at all but you may get what is refered to as a "spark knock." This again will not damage the engine. I suggest you experment with the different types of octane. In mine, I found it was overall worth while to go with premium. In my geographic region, my mileage and performance do best with this type, you may find the lower octane savings is not trully that because of a more effiecent useage of premium fuel.
yes premium gas is required
