There isn’t a single Fram oil filter number that fits every 2018 Jeep Grand Cherokee—the correct part depends on the engine in your particular Jeep. Fram offers multiple filter lines that cover the different powertrains used in that model year, so identify your engine and match it to the Fram catalog or a trusted retailer.
Understanding the 2018 Grand Cherokee's engine lineup
The 2018 Grand Cherokee was offered with several engines, and the correct Fram filter is engine-specific. Fram’s catalog (as of 2024) shows multiple part numbers that fit each engine. The primary options were:
- 3.6-liter Pentastar V6
- 5.7-liter Hemi V8
- 6.4-liter Hemi V8 (SRT models)
- 3.0-liter EcoDiesel V6 (where equipped)
Because Fram produces different filters for each engine family, the exact part number isn’t universal across all 2018 Grand Cherokees. Always verify with the filter finder on Fram’s site or cross-reference using the VIN to ensure a precise match.
How to identify the correct Fram oil filter for your Jeep
To lock in the right part, follow these steps:
- Check the engine code in your owner's manual or under the hood to confirm whether you have the 3.6L, 5.7L, 6.4L, or EcoDiesel engine.
- Inspect the current filter: the part number is often printed or stamped on the canister or indicated on your service receipt.
- Use Fram's Filter Finder: visit Fram’s official website and enter year, make, model, and engine to retrieve the exact part number.
- Consult a parts retailer with your VIN: a parts counter can cross-reference Fram numbers for your exact configuration.
- Double-check thread size and gasket diameter: while Fram filters for Jeeps commonly use standard automotive thread sizes, verify the specifications of the filter you select.
Once you have the correct Fram filter number, choose the appropriate filter grade for your driving conditions and oil type. If you are unsure, consulting a professional mechanic can help ensure you select the right option.
Summary
The short answer is: for a 2018 Jeep Grand Cherokee, there isn’t a single Fram filter number. The right part depends on the engine (3.6L, 5.7L, 6.4L, or EcoDiesel). Use Fram’s online lookup, check your VIN, and verify with a retailer to obtain the exact part number for your vehicle. This engine-specific approach helps ensure proper fitment, filtration performance, and ongoing engine protection.
