Longer Service Interval= 7500 miles.
-Mobil1 Extended Service= 15,000 miles.
It is not BS: Mobil1 ES can be utilized over the recommended 15,000 miles that they guarantee. Amsoil Ea oil filters are guaranteed 15,000 miles. If you so choose to replace an oil filter on our cars every 3,000 miles, it's no big deal. Bleed back of motor oil is minimum and you add a 1/2 quart. Done in 5 minutes.
- It's your personal choice.
- I accidentally ran the Mustang without any antifreeze on a 100 degree day without pegging the temp gauge but it got hot. Caught it just in time and I was extremely glad I had the added protection in the engine oil. I will keep using it as I approach 300K miles.
