Oil for all intents and purposes...Oil is oil. Don't listen to marketing listen to engineering. Marketing is gonna throw all these different numbers on wear stats at you for the sole purpose of confusion. Then 100k miles later you realize oh my engine is still running and I've been spending 80 bucks per oil change meanwhile the guy using mobile 1 ep down the road spending 30 bucks a change. His car is still running too. Wtf.

I'd never buy "Thrifty" oil for my car. I wouldn't when I was in high school and it said 30W right on it just like Castrol. Oil may be oil but I paid 4 times more for the name brand.

Why not? Have you ever herad of a petroleum company called "Thrifty Oil"? Probably not because "Thrifty" oil is bottled by Mobil or Shell or other ?????? and just put Thrifty's name on the bottle.

Mobil Oil refinery order desk:

"Hey, Jack! That batch of 500,000 quarts of oil, run 400,000 into our bottles and 100,000 into the Thifty's."

I buy whatever's on sale. Never had an engine failure yet due to an "inferior" oil in 40+ years of owning/maintaining vehicles.

I just do not trust it. It is the or other ?????? that concerns me. A complete unknown. I assume then in 40 years you have used quite a bit of Thrifty oil as it is the cheapest, and no problems. Or what is cheaper than Thrifty if I might ask?

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!
