Petra Service Benefits covers Chrysler, Dodge, Jeep and Ram vehicles. Each one is reviewed against its own maintenance schedule and the way it is driven.

Durango, Charger and Hornet
Performance engines, including turbocharged ones, put extra heat and stress on engine oil. Your advisor can review oil service along with Petra Engine Shield and fuel system cleaning.
Wrangler, Gladiator, Grand Cherokee, Compass and Wagoneer
4x4 systems that see trails, mud and water crossings depend on clean drivetrain fluids. Differential and transfer case service get a closer look on every Jeep review.
Ram 1500, 2500, 3500 and ProMaster
Towing, hauling and long I-45 runs work the cooling system and drivetrain hard. Your advisor confirms which services fit your gas or diesel Ram.

Kramer CDJR Madisonville serves drivers throughout Madison County and along the I-45 and Highway 21 corridors. Many of our customers drive in from Huntsville, Bryan, College Station and Hearne, and long highway miles, summer heat and towing all affect how quickly fluids and filters wear.
Bring your vehicle in during your next oil change and we will walk through the mileage review points that apply to how you drive.
It is a structured maintenance review built around mileage points from 5,000 to 90,000 miles, paired with three professional-use Petra treatments: Engine Shield for engine oil, Fuel Power II for fuel system cleaning and Universal Cooling Treatment II for the cooling system. Your advisor uses it to show what your Chrysler, Dodge, Jeep or Ram may be due for and why.
Each mileage point lists the services worth checking at that stage, such as brake fluid, cooling system and fuel induction cleaning at 30,000 miles. They are review points, not automatic replacements. Your advisor confirms each one against your vehicle's maintenance schedule, inspection results and service history.
Petra Engine Shield is compatible with conventional, semi-synthetic and full-synthetic engine oils. Petra Universal Cooling Treatment II is compatible with conventional, hybrid and extended-life/OAT coolants. Your vehicle should always be serviced with the engine oil and coolant that meet the specifications in your owner's manual, including Ram heavy-duty and diesel models. Your advisor confirms those specifications and whether a Petra treatment is appropriate for your vehicle before any service.
Every recommendation comes with an advisor estimate, and nothing is performed until you authorize it. You can approve services for today, plan others for your next visit, or simply discuss them with your advisor first.
