$19.96 minus 15% S&S for $16.97.

There have been better deals at low as $13 but this is not too shabby for a non-rebate price.

This is for 5w30 and 5w20. 0w20 is more expensive.

product is fine but check the prices for the single vs 3 pack... not sure why, but they are charging a lot more for the 3 pack... they tricked me on my last order (yes, that is on me) so just fyi so others don't make the same mistake

Regularly check Walmart online. I've scored Quaker State for $13 before. They also have the in store brand Super tech for $14 everyday low price if you can't find a sale

Hate to say but this is no deal at all. If you are going to drop more than 15 bucks it should be on pennzoil. Most other ones are no better than your everyday super tech which is really good oil. Also I work with a lot of engine mechanics and they say you should keep with the same oil package if possible. While I'm not as picky as they are there are a number of subtle differences to how wear and varnish affect certain engines especially turbo and gdi. So ymmv but I have always been told pick an oil and stick with it. I think for the normal driver it doesn't matter tho.

Honestly I've found on my truck it likes castro more.. just at start up.. I stick too full synthetic high mileage on mine but for example I've used Amazon's and it seemed like it clattered more from dead startup vs this where it was non existent. Of course I put enough in and all but still old engine high miles for sure so it could be picky in what it likes.

While I'd agree with you that Pennzoil is better this is actually still a pretty good oil and still better than a supertech, kirkland, or amazon basics because those are literally the cheapest possible engine oil you can buy that still just barely meets dexos1/API SP I mean those are like razor thin passes on those tests because cutting any additive and VM use in there means more profit and lower prices.

As for why a Pennzoil or Castrol EDGE is better, they have larger additive packages because they need to meet higher specs such as ACEA and European OEM specs such as VW or BMW. Those additive packages can be double the treat rate of the skinny supertech stuff.

Castrol Magnatec is in between, not a low end treat rate but not as high as an EDGE. Easiest way to tell is look at the specs they meet. API/dexos1 is basic but big companies such as Castrol, Pennzoil, Valvoline etc. will go out of their way to differentiate their products with some aspect of higher performance. You don't need that when you buy based on lowest bid.
ACEA is better
Mercedes benz, VW, BMW specs are pretty much tops

Fun side info, Magnatec has a cool solid additive that's like a wax so when the engine cools it solidifies on the metal and protects until the engine warms up. Was proven that additive could reduce Sequence IV wear tests consistently so they ran those stop/start wear protection ads.

Ignore specs for Ford, Chrysler, etc. as they are basically
API with slightly higher requirements but not by much.

So what's a decent cheap 5-30w to use in my 4-banger Camry with 270,000 miles? I usually get 5 quart Quaker State cheap at WalMart.

Is this going to be another 20 page oil discussion? At the end of the day, the differences in all these Full Synthetic oils are so miniscule (like the molecules and additives and yadayadayada), that no one will ever notice the difference, not even your engine. And if you say you can tell what full synthetic someone puts in your car simply by driving it, I have placebo to sell you.

I also know somebody that knows somebody that's a mechanic, my brother-in-law, who's been a mechanic for nearly 40 years. "Whichever name brand full-synthetic is the cheapest, just buy that one. You'll never keep your car long enough for your engine to fail because of what oil you picked. Something else will fail before the oil causes your engine to fail."
