I have many good results related to MOBIL 1 full synthetic in all of my vehicles. I use the 20,000 mile version and I swear by it. Additionally, always use the maunfactures recommended or insisted (in the case of turbo charged engines) oil filters. Some substituted off-brands are real garbage.
I will not try to sell you on any particular brand of oil, but make sure it meets the basic requirements like viscosity (i.e. 5W-30, 10W-30), DEXOS1 Gen 2, API SN Plus, SN, SL, GF5, GF4. I personally have been using Costco Kirkland brand 'Full Synthetic' and AC Delco oil filters for 3yrs now, changing every 4-5k miles. I even tow a 16ft Travel Trailer 4x a year. For vehicles that use conventional oils, then I would say to use High Mileage oils, but not with synthetics.
