If you don't have any issues, keep doing what you are doing. I'm not a fan of RP, but some here like it. You can also try some "German Castrol". Search for that or "GC" and you can find lots of threads. Otherwise, don't worry about it.

BTW, turn off the CAPS-LOCK, it means you are screaming when everything is capitalized.....

I have 161,000 + miles and have been using Mobil One high milage 10-40 for the last 30,000 miles...the car uses 1/2 quart of oil every 5,000 miles...before I started using the Mobil One high miles oil I used 0-40 Mobil One and had the same oil consumption... if you are having good results with a particular oil I would say stick with it..

Stick with mobil 1 thats all marketing.

Get mine at Wally World for 24 bucks for 5 quarts. Usually buy 2 5 quart jugs at a time, with a high grade filter. Also change it every 6,000 miles.

High Mileage oils are more than marketing, Main difference being that they are blended thicker, and they use seal softeners to condition the seals to stop and prevent leaks at the valve seals and such. And they do usually rob you of some performance and gas mileage, and use adititives that can negatively affect emissions equipment. Thats why most are not API or Ilsac certified. They are meant for older 15year+ cars that are prone to smoking and blowby. Dont use them unless you need too.
