What This Oil Helps Address

• Cold-start wear during low-temperature starts
• Oil breakdown from heat and extended service intervals
• Viscosity loss in turbocharged or high-output engines
• Fuel economy loss caused by heavier-than-specified oil
• Routine maintenance for vehicles calling for SAE 5W-30 synthetic oil

Installation Notes

Use only in engines that specify SAE 5W-30 and confirm the required oil specification in the owner’s manual. Verify the correct service fill capacity for your exact vehicle before draining and refilling. For fitment-based searches, this part is commonly selected for Audi RS6 Avant, BMW M3, and Ford F-150 5W-30 service applications, as well as Mercedes-Benz and Porsche models that call for the same viscosity grade.

Part number 3703-320 should be matched to the vehicle’s oil specification, not just the model year. If your application lists an alternate oil grade or a special manufacturer approval, follow that requirement first. This part number, 3703-320, is also a useful reference when searching for ENEOS 5W-30 synthetic motor oil by application.

Quality Assurance

ENEOS Fully Synthetic Motor Oil 5W-30 is formulated to meet API SP, API SN/RC, ILSAC GF-6A, and Dexos 2 standards for modern engine protection and performance consistency.
