“I am a true believer in Mobil 1, and I enjoyed reading your documents and test.”
“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”
“Curious as to what your thoughts are for the best protecting synthetic motor oil "off the shelf" selections”
“Curious as to what your thoughts are for the best protecting synthetic motor oil “off the shelf” selections. Got a 2000 GMC Sierra w/5.3L. Has 262,xxx miles on original motor,transmission,ect. Everything is stock and just want to keep it running great as long as possible. Also I don’t mind paying the premium price for synthetic motor oil as long as I know I’m getting a product with a quality BASESTOCK. Definitely do NOT want a high percentage group III hydrocracked basestock. Thank You.
