What Makes a Great Engine Oil?
Great engine oil does four key things. It lubricates moving parts. It protects them from wear. It lasts a long time. And it helps save fuel. That’s what I look for when I choose oil for my car. If it can’t do all four, it’s not worth the price.
I’ve tried cheap oil before. Big mistake. The engine got noisy fast. It ran hot and rough. But when I switched to Mobil 1 or Liqui Moly, the car felt smooth again. The engine stayed cool and quiet. Oil color stayed clean, even after months of use.
For most U.S. drivers, synthetic oil is the best pick. It flows better in cold weather. It holds up under heat. And it lasts longer between oil changes. That’s why more brands now recommend it. If you drive a Toyota, Honda, Ford, or a newer BMW, it likely needs synthetic from the start.
So why compare Liqui Moly oil vs Mobil 1? These are two of the best. Mobil 1 is easy to find and used by brands like Porsche. Liqui Moly is made in Germany and trusted by top Euro brands like Audi and BMW. I’ve used both—and I trust them for very different reasons.

My Real-World Experience: Testing Both Oils
Engine 1: 2018 BMW 330i (5W-30)
I first tested both oils in my 2018 BMW 330i. It’s a turbo engine, so I notice small changes fast.
With Liqui Moly, the idle was quiet. Cold starts were smooth. The engine felt calm and steady.
It made my BMW feel like new again.
Mobil 1, on the other hand, felt quicker. When I pushed the car, it responded fast.
At high RPMs, Mobil 1 had the edge.
Fuel use was close. Liqui Moly gave me about 27.3 mpg. Mobil 1 gave 27.6 mpg.
Mobil 1 saved a little more gas.
After 5,000 miles, the oil color changed. Mobil 1 looked darker, likely from strong cleaners.
Liqui Moly stayed lighter, and the oil cap looked cleaner too.
Engine 2: 2016 Honda Accord (0W-20)
Next, I tried both oils in my 2016 Honda Accord. This car does it all—city, highway, short trips, and long drives.
Mobil 1 gave better gas mileage, around 32.8 mpg.
It’s great for long drives and daily use.
Liqui Moly made the engine quieter. It felt smooth, even at low speeds.
Over time, I saw less oil burn with Liqui Moly, which impressed me.
In stop-and-go traffic, Liqui Moly felt better.
But on long highway drives, Mobil 1 stayed strong and steady.
Final Take from My Tests
Both oils are great. But they shine in different ways.
- Liqui Moly is best for smooth, quiet driving. It’s perfect for Euro cars and people who want top-tier feel.

Which Performs Better by Category?
1. Protection & Wear
Both oils protect well, but Liqui Moly has a slight edge thanks to its molybdenum additive. This metal helps reduce friction and wear, especially when the engine is cold.
In my BMW, I noticed Liqui Moly made the engine feel smoother at idle and during slow traffic. That tells me it’s doing a great job keeping metal parts from rubbing.
Mobil 1 still holds its own. It’s built to take heat and pressure, especially under load. I’ve used it in summer road trips and it held up like a champ.
For high heat or hard driving, Mobil 1 works great.
2. Cold Start Performance
If you live where winters get rough, Mobil 1 is your best bet. It flows fast in cold weather, which helps protect your engine right from the first turn of the key.
In my Honda, starts were smoother and quicker with Mobil 1 on cold mornings. That quick oil flow matters when it’s freezing out.
Mobil 1 wins in cold starts.
Liqui Moly also performs well, but it felt just a hair slower to warm up. Still smooth—just not as instant as Mobil 1 in sub-freezing temps.
3. Engine Cleanliness & Deposit Control
Mobil 1 is great for keeping your engine clean. It’s loaded with detergents that help scrub away build-up. That’s why it’s a favorite for older engines or those that see lots of miles.
When I drained the oil, Mobil 1 looked darker, which shows it was catching more grime. That’s a good sign—it’s doing its job.
Liqui Moly stays clean-looking longer, and it kept my oil cap spotless. That’s likely from its high-purity base oils.
For long oil life and less sludge, Liqui Moly shines.
4. Price and Availability
This one’s easy. Mobil 1 is cheaper and easier to find. It’s at almost every big-box store, auto parts shop, and even some gas stations. I’ve grabbed a jug at Walmart more than once.
Liqui Moly costs more and isn’t sold everywhere. I usually have to order it online or visit a European car shop.
If you want convenience and value, Mobil 1 is the clear winner.
But if you’re okay paying a bit extra for that smooth Euro feel, Liqui Moly might be worth the splurge.
Best Use Cases by Vehicle Type
For Daily Drivers (Toyota, Honda, Ford, etc.)
If you drive a car to work or school every day, Mobil 1 is a smart choice. It’s cheap, easy to find, and works well.
I use it in my Honda. It keeps the engine smooth and saves gas.

I put Liqui Moly in my BMW. It made the engine quiet and smooth.
Liqui Moly is best for high-end engines that need extra care.
It costs more, and you may need to buy it online. But it feels worth it if you want top quality.
Mobil 1 still works well here. It has the right approvals. But Liqui Moly gives a better “feel” for Euro engines.

Use Mobil 1 for daily cars like Toyota, Honda, or Ford.
Use Liqui Moly for Euro cars where smoothness matters most.
