You may not have to do it, depending on the design of the engine and your driving habits. We haven't had to do it to our Ecoboost. But we drive the hell out of it without many cold starts.When I bought my 2.0T, I budgeted in having the carbon buildup cleaned every 65K or so. I know it’s more expensive, and I know I am taking a chance, but it is just so much more fun and capable, for my applications.
With that said, I bought my wife a 2020 Sahara with the 3.6. I love it too, but a few fractions less than my 2018 2.0T.
I also wonder if the new SN+ and SP oils take care of the buildup, too, or at least help with it. I've been running Mobil 1 EP 5w30 for 10,000 miles per oil change in the Ecoboost and it is doing very well. I obviously can't see the valves, but it runs strong as ever and sounds great. It has about 60k on the second engine. The first engine was destroyed due to an error by a kid who changed the oil at a local oil change place. Cost their insurance company about $12 grand. OUCH! But that Ecoboost had 80k and was perfect until the screw up. Same deal, 10k changes on Mobil 1 EP. Our Ecoboost(s) are gen 1, so they are supposedly vulnerable to the valve deposit build up. Time will tell.
So if you budgeted it and it doesn't need it, you've got more money for Jeep mods! Lol!
