I have become very money conscious or saving a ton. Sold most of stash and my old hi def tv. Considering going back to QSGB for 5k ocis. I know; i am nuts. Or, i can get Federated conventional oil for $1.49 quart thru work
I just recently just ran "Everest" syn blend oil. Cheapest I could find. About $8 US for 5 liters. Ran it all winter and past what the OLM on my car said to go. Sent a sample to Blackstone, results were less wear metals than the average that Blackstone tracks. I can't see how you can go wrong with an oil that meets SAE SN specs unless you have some fancy turbo gizmo. QSGB will be fine.
