Very Good At Capturing Debris Of All Sizes
I have been using this for my 2015 Acura RDX for several years and each time I replace it, the old filter seems to do the job in capturing big and small debris.

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!
