Hi,

I kind of wanted to use the STP Gas Treatment on my 3.8L to see if it works or not, but I wasn't sure which one to use. They start from 8, 12, 24 Fluid Ounce/Bottle and all them say to use a bottle every fill up(doesn't say what how much is the fill up) so does any one know which one I should use for my Genesis?

Thanks

None, just use premium gas & you will be fine. But do have your throttle body cleaned every once in a while.

So should I use the Fuel injector cleaner every once in a while?

No. From what Ive heard the injector cleaner is pretty much kerosene and doesn't really do much.
The only one Ive ever seen work good is seafoam and that's on 100k+ motors...

You can, but it will make little difference as todays fuels already have most of these chemicals built in. I personally throw some in about every 10k miles, but only because it doesn't cost me anything. My father gave me a case of BG 44k which is about the same thing.

Those are all a waste of money.
