A bottle of this every other month plus using high quality 93 octane fuel is all you’ll need to keep the fuel system clean.

Also, Chevron Techron will also work but it’s not as powerful as the product below.

SI-1® Complete Fuel System Cleaner

Cleans injectors, carburetors, valve and combustion chamber deposits with a concentrated blend of the most powerful high-temp and low-temp detergents available

I'll check it out, TY! I only run 93.

With dual injection (Gen 2 and 3 Ecoboost), the 'GDI service' is absolutely not needed until much higher mileage or if there is an actual carbon problem to address.

I run 93 with Chevron Techron every oil change (Amsoil S&S every 5k for me now). If the truck was new to me at 60k, I would consider the other suggestions in this thread to be spot on (tranny, diff, coolant, etc..); and I would certainly also run the Valvoline R&P for a few oil changes, it is pretty effective.

Gotcha, TY!

I also have the Ford Warranty through 100K and I'm also obsessive about regular maintenance. I plan on doing diffs/transfer/transmission & filter every 50K because I just want this sucker to run till it dies past 300K. May be overkill but it's gonna be hella clean. I have a 23 Tremor and when I got it didn't trust anything the previous owner did when 1. the oil filter was tighter than s*** and then 2. Engine air filter was almost clogged. Did Amsoil and Pennzoil Ultra Platinum first 2 oil changes (25K and 30K), cleaned all the air sensors, and put in new plugs at 30K. They didn't look horrible but I think the previous owner had it as a work truck and let that thing idle a ton. Also got a new battery because it was dying. Unrelated, put in a new intake.

Long story short, I plan cutting all the service intervals either in half or by a 1/3 depending on what it is. Did brake fluid drain/replace since that recommended every 3 years, little overkill to do it sooner imo.

Nice!! I agree. I did everything but the GDI.

As MOE7 said earlier- with the Gen II ecoboosts, they added a second injector to each cylinder to keep the valves and intake track clean. There still the direction injection in the cylinder, but then a second one up in the intake track to keep the valves washed in fuel.
