Ace Barker Posted December 15, 2006 Share Posted December 15, 2006 I recently retired my RX 300 after 200K and bought an RX 350. I know it reads premium fuel in the literature but if I useregular fuel, what sort of issues might I have? Pinging, engine damage? A friend has a new Corvette and runs regular fine and it is supposed to use premium. He said around town and normal driving hasn't caused any problems. I will put a lot of miles on the RX 350 each day driving all over the state of Georgia. (300+ Highway) It adds up paying the difference between premium and regular. Thanks! Ace...

Use premium, If you can afford a rx then you can afford to use the recomended premium gasoline. Or you can always trade it in on a chevy and burn regular. :whistles: Link to comment Share on other sites More sharing options...
Ace Barker Posted December 15, 2006 Author Share Posted December 15, 2006 Thats what I figured. Not an affordibilty issue and I don't want to damage anything. Trying to be frugal with the miles I put on it. I ran regular in the RX 300 and bought it new. I never paid attention but maybe I shold have run premium in it as well? I had 200K with no problems.

Not sure on the 300 but on the 330 they say you can use regular but the 'preferred' gas is premium. I do notice a noticeable difference in engine performance when I use premium....

SKperformance Posted December 31, 2006 Share Posted December 31, 2006 Closed as this is an ongoing debate not engine specific as most Toyota's all use similar compression and timing . There is a huge debate in the general section , please feel free to add comments there as it is the same ideas over and over again. thanks Link to comment Share on other sites More sharing options...
