Jeep specifications at a glance
Current-generation figures for every Jeep we cover. Specifications are set by generation, so older model years may differ, each model page breaks them out generation by generation.
| Model | Years | Engine oil | Battery | Tyre size |
|---|---|---|---|---|
| Grand Cherokee | 2012–2025 | 0W-20, 5 qt | Group H6/Group 48 AGM (main, under the driver's seat) + Group 14 auxiliary ESS battery (under the passenger seat) | 265/60R18 |
| Wrangler | 2012–2025 | 0W-20, 5 qt | Group 48 (H6) with stop-start-equipped engines; 94R (H7) on engines without stop-start | 245/75R17 |
How we verify Jeep specifications
Every figure on these 2 nameplates is checked against owner’s manuals, Jeep service documentation, and NHTSA recall and complaint records, then labelled with how confident we are in it. Where a specification is safety-relevant and we could not confirm it to that standard, the page says so rather than guessing. Problems and recalls are attributed to the model years they actually affect, so a page tells you whether an issue applies to your car rather than to the generation in general.
