Describe ACEA Rating Difference on Mobil 1 0W-30 and Mobil 1 5W-30
I have recently switched from Mobil 1 5W-30 to Mobil 1 0W-30, and noticed that the 0W is only rated ACEA A1 while the 5W is rated A1/A5. What is the reason, and can you put those specs into layman's terms?

The testing required to obtain ACEA A5 has not been completed and there are no plans at this time to add this approval to Mobil 1 0W-30. If your vehicle requires ACEA A5 then you should switch back to the Mobil 1 5W-30 at your next oil change. However, like all Mobil 1 products, Mobil 1 0W-30 Advanced Fuel Economy is a strong oil that will provide outstanding performance in vehicles where it is used.
