What Our Reader Say...

We have helped many readers select oil for their cars.


I started using Mobil 1 oils while stationed in Dover Deleware approx 39 years ago. I have purchased approx 9 new vehicles over the years, and I have gotten over 300.000 miles on each of them with no major engine work on any of them. My current truck that I own now is a 2003 Chev PU with a 5.3L v8 with 360,000 miles. Runs like new. I’m thinking about changing from Extended oil to Annual oil. I am a true believer in Mobil 1, and I enjoyed reading your documents and test. Thanks. Coral
