Im getting my s4 na streetported, was wondering how big of advantages i would get from using the premix instead of the stock mop ?

Not really sure how advantageous it is to use the premix on a street car ? My plans are to do some racing but not constant heavy racing , hard on the pedal. I just want a good street car, the main concern for me to keep it stock would be the pain in the *** factor...but if there are more good things to using the premix than keepin the stock setup ill go for it, but if its just a waste of my time then why bother ?

From what i know it burns cleaner with premix, but can cause the injectors and fuel filter to clog (what i heard) , im not sure about the fuel pump ? But im getting new fuel filter anyways for my rebuild... i just wanna know what is in my best interest to do...

edit - I really dont know what kind of oil i should use if i run premix either...for the engine or for the premix.....I really want to use the best stuff for my car that will make it last , im not into using that cheapo depo ****. Even if I dont run premix i still dont know what to run...as i heard synthetics should not be used...but I think synthetics are better than regular oil , just imho.

 

There's lots of premix info in the archives.

Personally, I don't see the point. The stock metering oil system works fine, and no one has ever proven (without a resonable doubt) that premix is better in a daily driver/street application.
