Hello,
I have recently placed my order for a 2021 Trailblazer Active 1.3L AWD in Midnight Blue with the Driver Confidence, Convenience and Technology Packages.
I am in the Central NY area and I am looking forward to learning about New Trailblazer while I wait for delivery.

Welcome to the forum @dcbridgwater.

Were you always set on the Trailblazer or did your shopping list include other models too?
Well my 2006 Pontiac Vibe AWD was getting a little worn out with 276,000 miles on it so I was looking for a similar type of vehicle. Originally was just going to get a Trax like I lease for my wife, which she has been very happy with. But then I seen a Buick Encore GX and realized it fixed most of my complaints about the Trax, which are the gas fill on the wrong side of the car, no center console, and the huge speaker bulge on the doors making it harder to swing legs out when in a tight parking space. But even with the Buick Encore GX fixing most of my Trax issues I was never quite happy with the interior styling. Then I seen the 2021Trailblazer said this is what I want, I then looked into the Activ AWD features and realized it should meet my needs. I did however consider a Rav 4 and Rogue but never gave the serious consideration because I have always been a GM guy. The thing that made me most hesitant to get the Trailblazer was the Direct Injection Fuel system, which just seems like a bad idea in terms of reliability, I hope it proves me wrong. If one could only pick and choose the good points from many makes and combine them in to one you could come up with one awesome car.

Nothing wrong with direct injection. It is much more efficient than standard fuel injection. One of the the only known problems with DI is fouling of the injectors. DI injectors are placed in the combustion chamber vs intake manifold, so they are exposed to very high heat and pressure which allows deposits to form causing fouling. This is easily remedied by putting a bottle of injector cleaner in at least every oil change. I like to put a bottle in every couple thousand miles to prevent the deposits from ever forming. Lucas and Royal Purple are my favorites, but any name brand cleaner should work fine.

My concern is more the valves than the injectors, since there is no fuel passing over the valves to help keep them clean, that combined with the PCV gasses and oil vapor coking the valves since there is nothing to clean them and fuel injector cleaner won't help since it will go into the intake and past the valves. I know some people use a catch can to combat this problem. What I don't know is do these new 3 cylinder all ready have provisions to prevent this or if a catch can possible in this application.

Fuel injector cleaner doesn't go into the intake manifold, it's directly injected into the combustion chamber where it does help clean the injector and valves. Catch cans are good idea, but it's not clear what type of PCV system we have, so I'm not sure if it's worth it. Another thing to consider is any catch can will void your warranty and you won't pass emission testing if your state or country requires it. I've run catch cans on several vehicles and one way to bypass any problems is just to disconnect it when going in for warranty work or emission testing.
