Mobil1 Extended Performance Full Synthetic Motor Oil 5W-30, 6-pack of 1 quarts

excellent oil from an excellent brand. not to awful much you can say about it. it does what it is supposed to and protects the heart of your car. This is my go to brand after working on so many engines in the machine shop.

Mobile one is great motor oil we use it all our vehicles.

Great product and price.

Value for money, quality is great, my car is working great for at least 10K miles

Mobil# 1 Tri-Synthetic is one of the top motor oils on the market. The Extended Mileage is a special oil for engines with more than 75,000 miles. Highly recommended.

This expensive stuff seems to be a must i went with the $20 cheaper Mobil kit not made for high millage cars and after 2 oil changes the motor is clacking and leaking much more oil down it's back side over the transmission of my Ford 4.6L V8 i'll be going back to this version of their product seems to do a better job less leaking and much less cold start noise my engine has 160k miles on it with and unmeasurable amount of idle time which is the culprit since i live out of it there has been a few times i have fallen asleep in the winter with it running for heat and woke up 4-6 hours later idling is the worst thing you can do to your engine, most likely need new head gaskets or valve cover gaskets in the mean time the good stuff works.

I love Mobil 1. After having a very long conversation with Mobil 1 engineers at a display booth at a NHRA National event, they accepted my challenge to explain why their product was better. I am convinced.

As an engineer, I drill down a couple of layers when evaluating certain products. All technical specifications on this product indicate that this motor oil is arguably at the top in its field. More importantly, the technical data translates into 'real world' performance. While being a bit more expensive, I believe that it provides another layer of protection for my vehicles.
