Fuel Injectors:

[Lexusfreak]

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!

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

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.

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.
