Hey all,
I picked up some Quaker State Defy 5w30 on sale, and I noticed it doesn't have the API symbol. Will it be okay to use in the Aurora, or do I need to take it back and exchange it?

I've run it in several of my cars and no issues. My old S10 had everything that was cheap - both oil and filters and it's still running at 299,975 miles. WFIW, Quaker State is part of SOPUS - Shell Oil Products USA, so Pennzoil, Quaker State, Shell are all the same company. Pull the TDS from the below site. Defy has 25-50% more zinc additive in it - just what you want for reduced wear. www.epc.shell.com/ |

Yes I read on Bob is the Oil Guy that the reason there was no API starburst/donut was due to the increased ZDDP (likely not enough to harm the cat converter). Thought I would take a chance...

Rocinate - that makes a lot of sense. The EPA holds sway over the oil guys and if they put the sunburst on it, then the new cars could use it under warranty and claim emission defects when the cat gets fouled with the extra zinc. I think that's one of the things that happened in the new API update - lowered maximum zinc levels.
