What Could Be Better
Both brands perform admirably, but there are some minor drawbacks worth noting.
⚠️ Valvoline Cons
- Shorter Change Intervals: Most of Valvoline’s synthetic oils are recommended for 7,500–10,000 miles. Not ideal for those looking for extended oil change intervals.
- Availability: Some premium Valvoline products (like Advanced Full Synthetic) may not be available at all retailers.
⚠️ Mobil 1 Cons
- Price Tag: Mobil 1 products tend to be more expensive across the board.
- Overkill for Casual Drivers?: Mobil 1’s advanced additives and extended intervals may be unnecessary for vehicles that don’t see much action.
My Personal Experience
Over the past 10 years, I’ve switched between Valvoline and Mobil 1 across different cars—from a high-mileage Toyota Camry to a turbocharged Audi A4.
Here’s what I found:
- Valvoline felt great for everyday driving. The engine ran quieter, and I appreciated the clarity of product information. When I used MaxLife, my older car showed a noticeable decrease in oil seepage and smoother cold starts.
- Mobil 1, on the other hand, made a dramatic difference in performance during long trips and in harsh weather. My turbo engine felt more responsive, and the oil stayed cleaner even after 10,000 miles. I used Mobil 1 EP (Extended Performance) and didn’t see a drop in oil level after months of use.
So, which one did I stick with? I still use Valvoline in older, everyday vehicles and Mobil 1 for my performance car.
