    • Great price and quality, you won't be disappointed!
Size: 5 Quart Style: Extended Performance High Mileage Configuration: 5W-20
What can I say? It's Mobil One. I now have 305K on my truck and used this since day one. Not one issue and I borescoped my motor and it looks brand new inside. No BS

    • Better oil.
Size: 4 Quart Style: Turbo Diesel Truck Configuration: 5W-40
The oil made my 4N15 turbo diesel much quieter than Amsoil 5w30 Max Duty. It is running much smoother than before. I have also tried Hot Shot Secret 10w-40, but Mobil 1 felt much smoother and quieter and is much cheaper. I will be ordering again.

    • Great product at a good price, highly recommended
Size: 5 Quart Style: Full Synthetic Configuration: 5W-30
I've always had great luck with Mobil 1 synthetics. Good product at a good price. I typically change oil every 5000 miles even with the synthetic and all of my cars have always reached 200k+ miles. Like they say, oil is the life blood of a car and Mobil 1 certainly proves that to me

    • Reliable Full Synthetic Oil with Proven Performance
Size: 5 Quart Style: Full Synthetic Configuration: 0W-16
Mobil 1 Advanced Fuel Economy Full Synthetic motor oil has been consistently reliable in my experience. It pours smoothly, performs well in both cold starts and normal driving conditions, and helps the engine run quietly and smoothly. Oil changes using this product show good oil condition even after extended mileage, which reflects its strong protection and high-quality formulation. One of the biggest advantages is its reputation and consistency—Mobil 1 is widely trusted, and this oil meets or exceeds manufacturer specifications for many vehicles. It’s especially well-suited for daily drivers looking for dependable protection and potential fuel economy benefits without overthinking oil choices. The main downside is the price compared to conventional or store-brand synthetic oils, especially when not purchased on sale. However, given the performance, engine protection, and peace of mind, the cost feels justified. Overall, this is a solid choice for anyone who wants a proven, high-quality full synthetic oil for regular maintenance. It delivers consistent results and long-term reliability. ... show more
