Just bought a 2015 Renegade off Carvana. What are the first things I should do for maintenance/upkeep?

Hey all! I'm a new Jeep owner. I've just purchased a 2015 Latitude 4x4 Renegade with 63k miles on it. I was informed by Carvana that it's had an oil change within the last few months (didn't show up on the Carfax, but they said it probably got done during their reconditioning.). I am not trusting a "maybe", so I'm getting its oil changed this weekend. Other than that, what should I be doing with the Jeep to make sure it's road-ready?

On another note, what maintenance do you recommend for making this Jeep last many, many more miles? I plan on changing oil every 5k miles, but other than that I'm not sure what I should be doing besides keeping it clean and looking pretty. Do you use any special engine fluids? Should I use Premium gas? Run it for 10 minutes before I go for a drive?

I'd love to hear suggestions and feedback!

I'd say you're off to a good start with changing the oil and filter right off. Make sure the oil meets the Mopar specification for your particular engine.

The Renegade should give you a message when the oil needs to be replaced, depending on usage. Every 5K miles is on the too-frequent side.

And replace the engine air filter. Cabin air filter too.

I'd definitely replace the brake fluid. The requirement is every two years, no matter how many miles. If you don't know whether it's been replaced, replace it.

Beyond that, did you get an Owner's Manual with the Renegade? If not, manuals can be downloaded. There's an awful lot of good information in there. To include the maintenance schedule.

Replacing spark plugs may be in order, depending on your engine type. And I'd replace ignition coils at the same time.

Other than that, I'd get a good shop to do a thorough inspection of everything... Underbody, suspension, etc. They'll know what to do.

Special engine fluids? Like I said, Jeep recommends a specific oil specification, depending on engine type. Also coolant specification -- don't just blindly use generic green Prestone stuff.

What grade of gasoline to use depends on the engine. The Owner's Manual should tell you; I suspect Regular should be fine.

You mean idle for 10 minutes before driving? No.

The oil change warning is supposed to come up based on varying factors in addition to time and mileage -- like how many start/stop cycles the engine has, how it's run, etc. The current not-to-exceed intervals are one year or 10,000 miles.
i am in the process of chaging the air filter and cabin filter. the cabin filter looks tricky to do but a dealership charges an arm and a leg to replace it
I'm starting to think about the cabin filter too, since I drive some dusty offroad trails here in the Rockies.

It looks to be a bit tougher than on our VWs; but not too bad. You have to remover the glove box... Let me know how it goes.

Engine air filter is only supposed to be changed every two years or 20,000 miles. I do mine every year.
I put in SeaFoam every oil change into the gas tank.
How much of a potential issue are fuel injectors on these engines?

As far as I know, these engines (at least with the turbos) are direct-injection (yes?). For those that might not know, that means the fuel is injected directly into the cylinders, past the intake valves. As opposed to the older common-rail injection systems, where the fuel is injected prior to the valves.

And because fuel in direct-injection engines doesn't "wash" over the intake valves, those valves are particularly susceptible to getting crusted-over with carbon deposits. And nothing in the fuel (detergent additives, SeaFoam) will help with carbon build-up on the valves.

So SeaFoam might help with fuel injectors -- couldn't hurt. But not at all with intake valves.
As far as I know, the 2.4L Tigershark used Multi-point fuel injection instead of direct injection
Makes sense.

Point is, before someone invests in chemicals in the fuel tank to try to prevent or fix carboned-up intake valves, they need to know whether they're got a direct-injection or a common-rail injection engine. Direct-injection won't benefit from anything in the fuel tank, regarding the intake valves. Common-rail? Maybe...

I don't know what kind of injection my 1.3T engine has, but I'd suspect it's direct-injection...
