I've used this oil for years. I drive vehicles that are usually 10+ years old. Oil is changed at or before 5k miles, or with the seasons (I drive my truck once a week). Never had a problem. I think most oil is probably fine as long as you're changing it. Change your oil people!

I use this oil to top up one of my cars: 2006 Nissan Altima 2.5s.
You can use whatever oil you would like. Just change them every 5k miles. Scotty said, "oil change is cheap but new engine isn't."

Yes. 2 pk for $30 in store thru May 3. This deal is cheaper. I always use this oil for our 5 cars. Just got 5w20 and 5w30 delivered free.

Exactly. I have run this and Supertech full syn around 3-5k depending on how dirty it is. 👍 . Project farm did a few oil testing vids, and all full synthetic's did pretty similarly. Like you said, change regularly at or before 5k and it doesn't matter what brand you use.

These are one of the reasons why I might get a Costco membership again.. I also get the Uber discount cards and just other things you can't find at other stores. I do have a BJ's and a Sam's membership at discounts and try to rotate the names and credit cards so I could always get the discount it membership price but sometimes calls go when you get the discount membership items like this will pay for itself or big ticket items that have the 5-year warranties like TVs and such

Which is a better value between this and the larger 2-pack? Or do they come out to about the same?

Virtually almost every oil that's GF-7 and API SQ nowadays will be fine for 5k OCIs.
