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.

One of the best Oils out there
Size: 1 Quart, Style: 6-Pack, Pattern Name: Motor Oil, Configuration: 5W-30
Only Oil I will ever use in my older vehicle. Almost 200,000 miles and still runs great. The proof is right there. Change at reasonable intervals, 5000 max, don’t listen to the 10,000 mile BS. They don’t want your vehicle to last, they want to sell you a new one.

Very good option
Better than the oiled version, if you're not chasing track performance. Fit perfectly into my Accord. I still get 34MPG, so it's at least as good or better than OEM, and still better than other options you'll find. No complaints here.
