Mobil 1 Advanced Full Synthetic 5W-30 vs Mobil 1 Extended Performance 5W-30

Both are 5W-30 full synthetics from Mobil 1 in a 5-quart jug, and the difference is the service interval. Extended Performance is the step-up line built for longer drain intervals and harder use, while Advanced is the mainstream formula that covers most cars well. Owners rate both highly, and the shared Triple Action Formula means build and cleanliness claims are close. Buy Advanced for normal driving with regular oil changes; step up to Extended Performance if you push intervals or tow and haul.

• Choose the Mobil 1 Advanced if you change oil on a normal schedule and want the mainstream Mobil 1 formula most cars are specified for.
• Choose the Mobil 1 Extended Performance if you want the longer-interval, higher-durability version of the same 5W-30 synthetic.
