Here we go again
For the last 7-1/2 years, I have used AMSOIL XL 5W30. My car had 24K when I switched over and currently has 166,200 miles, and I've used a 10K oil change interval (I had been driving 100 miles a day for those 7-1/2 years, 90% highway), and I've had absolutely NO oil-related issues in my LFX V6. I also have AMSOIL in my manual trans and diff - again NO issues.
My wife's 2013 Escape (2.0 turbo) is also a daily driver - short trips mainly - and has had AMSOIL in it since last year (over 12 months) and is approaching 10K miles, with NO oil issues and it's due for its first change since the switch, probably next month.
So AMSOIL has worked extremely well FOR ME, in my two cars.
That being said, almost ANY, QUALITY synthetic (AMSOIL, Mobil 1, Redline and others) SHOULD give you the performance and protection you need. Just follow the OIL MANUFACTURER'S change interval recommendations.
