Default Fuel Injection cleaning

ISince I don't know much about all this I figured I'd throw an easy one out there for comment.

The only time I put injection cleaner in my GXP was the last oil change. I never really think about it but since I'm bored as hell at work I figured I'd ask... How often and what type?? Should I run an occasional tank of premium? That'* pricey but I'm good with it if there is a benny to it.

i believe your supposed to be running premium at all times with a northsatr motor, i know my Aurora required premium, since the aluminum engine tends to run hotter..
It took me a while to explain to wifey why she needed to use it, and finally she believes me, now that she is getting 23mpg instead of the 20.5 she was getting before, which more than makes up for the added cost, not to mention the better performance and longevity you will see with premium fuel


as for the injector cleaner.. I run Chevron techron in my car every 10k miles or so.. IMO there really is no need to do it any more frequently

You know your car requires premium fuel right?



At least what I thought and according too this article.

In regards to the fuel system cleaner, yes I have used that stuff every 3 months, however most modern fuels have enough detergents in them to keep the fuel system clean.

Default My Owners Manual

Because I have no clue I just ran out and grabbed the owners manual for the car. The reccomendation is 87 or higher for the V8. I'm glad they have a section in there for removing the gas cap... phew that had me confused

None the less I'm going to fill up with premium and see what happens to the milage.

Premium fuel has no more or less detergents in it than 87 octane. Only the OCTANE is different.

Yes, a Northstar should run premium for the OCTANE component.

Running injector cleaner in your tank is a waste any more than twice a year at the MOST considering the quality of modern fuels.
