Lexusfreak Posted February 5, 2004 Share Posted February 5, 2004 How often should one get their fuel injectors flushed on their ES (or is it even necessary at all)? I'm not sure exactly what gas the previous owner used before I bought it but I only use Sunoco Ultra 94 gasoline. - Also, does anybody recommend using a "synthetic" fuel system cleaner such as Valvoline Syn Power ever so often? Opinions on both issues are appreciated, thanks! Quote Link to comment Share on other sites More sharing options...
SKperformance Posted February 5, 2004 Share Posted February 5, 2004 use a good flush every 3 months or so, almost any $20 dollar one is good get a motorvac done about 130 and makes the car run like new it cleans the system out perfectly Quote Link to comment Share on other sites More sharing options...

steviej Posted February 6, 2004 Share Posted February 6, 2004 I throw a bottle of Chevron w/Techron (and yes, the synthetic formulation) in the tank with every oil change. That comes out to be about 3 per year. It costs less than $10 USD at AutoZone. steviej Quote Link to comment Share on other sites More sharing options...
monarch Posted February 6, 2004 Share Posted February 6, 2004 (or is it even necessary at all)? I doubt that any cleaners are needed, especially when using Premium gas. On my fuel injected 92 Toyota pickup I havn't used any cleaners for 436,000 miles and the engine still runs like new. I did experienced a few hesitations from time to time and these were always solved by scrubbing clean the goo that gradually developes over time on the throttle body plate and bore.
