View Full Version : SUBARU SA459 - works a treat - recommended.

I have been putting a can of this stuff through my wife's Pug 207cc Sport - turbo, direct injection, at every oil change.
Once scored a dozen for $120 from eBay.
Reason - to combat the carbon build-up on the inlet valve stems, a nasty by-product of direct injection.
Initially would throw a code and go to limp mode. But with my trusty $20 Chinese diag tool I could always erase the code.
However, for the last four oil changes, doesn't throw a code at all. Just goes to show that the gunk is being removed.


Never used it on the Red Jett - with catch can, etc.

So did it at recent oil/filter change (136,400 odo).

After start up, a reasonable amount of expected white smoke out the back, then sprayed the remaing SA459 into the intake manifold, not through the throttle body.


Excellent idling. On cold startup the Red Jett was always a bit cranky with it's Jim Wolf cams. Now, no conk out. Also a fine addition to a smoother engine acceleration.

I'll do it every oil change from now on. Sheeese.. That will be 1st june 2018 - as the Red Jett only does 2,000 klicks a year now.

If you need to know how to do, just holla'

Here are two videos of dudes doing it to their WRX.




ps: Wear gloves as I got a bit on my finger and it burned through two layers of skin!
