Every 2011 Jeep Wrangler is equipped with the same 3.8L V6 engine, making it easy to identify the oil capacity and type needed. Regardless of the trim level, you will always require 6.0 quarts of SAE 5W-20 full synthetic motor oil. If SAE 5W-20 is unavailable, you can substitute with SAE 5W-30, but it is not recommended for prolonged use. This is because SAE 5W-30 has a lower viscosity at operating temperatures, which can lead to increased friction in the engine system. While it will still lubricate the engine, it may cause premature wear and tear, potentially resulting in early engine failure. It is advisable to prioritize the use of SAE 5W-20, even if it comes at a slightly higher cost.
Am I allowed to utilize SAE 0W-20?
The 2011 Jeep Wrangler uses SAE 5W-20 oil with the API Certification Seal. It needs 6 US quarts (5.7 liters) of oil, and the engine filler cap indicates the right oil viscosity for your engine.
If I can't find 5w-20 oil, is it okay to substitute it with 5w-40 instead?
