When I was younger and had less money, I used thrifty oils. Never had a problem. Now that I am older and wiser

I use name brands but I don't just stick to one brand. I buy the one on sale and use synthetic oil primarily because the oil change interval is far greater than dino oils.

If you pay attention to the results of "what's the best oil", you will note that there is no definitive best oil. That's because "oil is oil" as someone noted. They all lubricate and remove heat. Now if you want to race your car, you may want to put in a 'racing' oil but they only last for a few hundred miles because that's how they are formulated. For DD like most mortals in here, any oil, dino or sythetic, will give you many, many miles of motoring as long as you change it regularly. Me? I change mine once a year regardless of mileage. Synthetic oil doesn't need to be changed every 3750 miles and/or 6 months. It will go triple the distance of dino oil without issue. And if your oil turns dark, it's most likely a result of repeated heat cycling and not a bunch of 'dirt'. We have filters to protect the engine from dirt particles that are big enough to actually do damage to the engine. So, my advice? Take oil threads with a grain of salt. Use oil and change intervals recommended in your OM for the type of driving you do. Don't overthink oil!

If you stay away from the crappy oils and change your oil/filter often, the worst-of-the-good will only knock a few thousand miles off the life of your DD engine (150K?) - if that much. As pointed out, racing/tracking is another story.

I use Amsoil Signature series in mine. Main reason, I can get it at dealer cost (brother has an Amsoil Dealer's License, and there is a distributor right here in Orlando). I do pay more for it than say Mobil 1, but I tend to do that on my cars. Merely a personal choice, I'm not going to stand on some soap box and declare that my oil is superior to others.

Check the "oil nerd" thread -- I seem to recall there being some UOA's on the Quaker State synthetic...

I will say this much: After pouring over numerous UOA's for the 370 and 350 motors, and also sending my own samples to Blackstone for analysis, across users' UOA's Redline has performed really, really well, and surprisingly, showed better wear characteristics than typical favorites like Mobil 1.

So, FWIW, I've been sticking to Redline.
