The best option there is
Size: 5 Quart, Style: 3-Pack, Pattern Name: Motor Oil, Configuration: 5W-20
I believe this is the best option available. I have a high-mileage truck (over 200k miles and still running great), but standard 4-6k-mile oil changes were costing me over $100 per service, so I wanted to start doing my own oil changes again. I also didn't want to be crawling under the truck every few months, either. This oil offers 15k-mile protection, which, when coupled with a quality filter, cuts my oil changes to once a year, saving me money on changes and still offering high-quality motor lubrication and protection.

This is good stuff!
Size: 5 Quart, Style: 3-Pack, Pattern Name: Motor Oil, Configuration: 5W-30
I use this oil in all my vehicles. Pennzoil just makes some of the best engine oil on the market. IMHO!

Oil jugs in a box
Size: 5 Quart, Style: 3-Pack, Pattern Name: Motor Oil, Configuration: 5W-20
yep, it's oil jugs in a box. The jugs matched the box and what I ordered so there's that. I put it in my car and the engine didn't explode so that's even better. It's oil people.

Full synthetic in new cars
Size: 5 Quart, Style: 3-Pack, Pattern Name: Motor Oil, Configuration: 5W-20
Looked on YouTube pennzoil full platinum high mileage is rated number two in oils good for your car it’s supposed to have good engine protection for 7000 miles. Good fuel efficiency, but that remains to be seen.
