I like Mobil 1!
I've been running Mobil 1 (standard full syn) for over 25 years, in about 14 different vehicles... and I've never had a engine or component failure due to oil... including 3 trucks that went over 200K. It's good oil. I'm sure there are a few better ones out there, but Mobil 1 is consistent, available, and priced well for what it is. It is certainly better than some others...

Reliable Full Synthetic Oil with Proven Performance
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.

Better oil.
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.

The oil I trust for my Toyota 4Runner
I use Mobil 1 Advanced Fuel Economy full synthetic in my Toyota 4Runner and it’s been great. The engine runs smooth, starts up easily, and I’ve never had any issues between oil changes. It’s one of those “not exciting but important” purchases that I don’t mess around with. What I like: • Smooth, consistent performance in my 4Runner • Easy cold starts • Reliable quality and easy to find • Gives me peace of mind for regular maintenance I’ve used this for multiple oil changes and plan to keep sticking with it.

No need to say
Mobil 1 is the frontrunner in engine oil products, and I have been using this for my European cars for years. The mileage and fit for engine protection is what you would expect. The quality is high and the performance on my car is clearly obvious with a smooth operation. The mileage coverage is great and listed over 10,000 miles but I usually change it by then and within a year.

Great oil, engine runs smoother and quieter
I started using this Mobil 1 15W-50 in my scooter, and I noticed the difference right away. The engine feels smoother and quieter, especially on longer rides. It also handles heat really well, which is important for daily use. The oil still looks clean after many miles, and I feel more confident about engine protection. I’ve tried cheaper oils before, but this one definitely performs better. It’s a bit more expensive, but for me it’s worth it. I will continue using this oil and recommend it to anyone who wants good engine protection and reliability.

Its a solid choice for maintaining engine health and performance
This motor oil is a good value for the money. I’ve purchased it several times and use it every 5,000 miles when changing my oil. It functions exactly as it should, and I haven’t noticed any unusual engine noise when using it. The oil has a beautiful golden color when poured and helps extend the life of my engine. One container is sufficient to fill my car’s requirements. Pros: Good value for the money Smooth engine performance with no unusual noise Beautiful golden color Helps extend engine life Cons: None observed Conclusion: Overall, this motor oil is reliable, effective, and convenient. It’s a solid choice for maintaining engine health and performance.

Great quality and price.
This is the oil weight called for in a 2024 Kia K5 with the 1.6T. Great quality oil and value.
