What would benefit me the most if I decide to switch over to premium fuel only.? Already need new spark plugs.

 

Stock

 

No benefits of going to premium fuel with N/A

 

Premium fuel will help clean your engine i believe. With a tune on 93 and a few bolt ons you could gain 20-30hp

 

What should I do if I decide to get the Stage 2 Hahn turbo kit down the road?

 

Once you get that turbo on then yeah use premium

 

so right now that i have it stock i should just keep it with regular gasoline?

 

I would

 

Umm bad advice here. 2.4 is designed to run on premium and will pull timing with regular until its no longer knocking. Sure it runs on regular, but you are down on power.

 

Correct.

Stick with the stock plugs. They are good.

 

My bad then 2.4 is a totally different engine then

 

The 2.4 was considered a H.O. engine, and had the same instructions as a stock SS/SC in terms of fuel.

 

Premium doesn't clean your engine. It's all about that knock yo. As said before, if the ECU pulls timing then you're down on power.

 

Thanks everybody very useful info

 

This is news to me as well. I've always ran mine on 87octane. Guess I'll start throwing 93 in her.

 

In a way I believe it does. Part of the reason it costs more is because of the detergents and lubricants they add to it.

 

Not really, it all depends on the fuel carrier. Octane rating does not depict detergent ratings, whether or not the fuel carrier is apart of the Top Tier Program does though. The attachment is a bulletin from gm that has a list of Top Tier Stations as of July.

*edit: Kinda hard to see the list, this link will take you straight to the toptier website which has
the list also. Top Tier Gasoline

 

That's good info, thanks for the list. I'll stick to those places from now on.
