Review on 🔧 Mobil 1 Advanced 15W-50 Full Synthetic Motor Oil - 5 Quart for Optimal Engine Performance by Julian Davidson

Mobil 1 Fully synthetic oil was my oil of choice for all my vehicles. I've been using this oil for 20 years and it has never let me down. Doesn't leave engine deposits like Pennzoil, Halvoline or Castrol. I typically run this oil 10,000 to 12,000 miles straight and change the oil myself. The oil will retain good viscosity and color even after a run. I have been a mechanic for over 20 years and have seen the inside of my engines on various repairs, seeing is believing. My personal vehicles have been used on a 1980 Toyota Pickup, 1983 Toyota Pickup, 1987 Ford Bronco II, 1989 Chevy Corvette, 1995. Mitsubishi 3000 GT, 2001 Subaru Forester, 2005 Subaru WRX STi, 1995 Jeep Wrangler, 1995 Ferrari F355 Berlinetta, 2001 Porsche Carrera 911 (996), 2013 Hyundai Accent.
