When it comes to choosing the best motor oil, the debate often boils down to AMSOIL vs. Valvoline. Both brands are well-known and trusted by car enthusiasts, mechanics, and everyday drivers. But how do they compare when it comes to performance, protection, and value for money? I’ve spent time looking at both oils, so let’s break down what I’ve found.
The Cold Flow Challenge
One of the most telling tests for motor oil is how it performs in extremely cold conditions. After all, the last thing you want is thick oil that can’t circulate when you start your engine on a chilly morning.
I recently saw a comparison of AMSOIL Signature Series and Valvoline’s High Mileage Max Life oil. The test involved freezing the oils at temperatures as low as negative 40°F. The AMSOIL Signature Series, being 100% synthetic, showed impressive performance in these freezing conditions, with minimal thickening. Valvoline, while still a good product, struggled a bit more under extreme cold. The AMSOIL oil maintained its fluidity better, proving its cold-flow superiority.
Now, some people might think that oil viscosity is only an issue in freezing temperatures. But it’s also about how the oil performs when it drains down into the oil pan after the engine has been turned off for a while. The next morning, when you start the car, the oil needs to circulate quickly and protect the engine. AMSOIL’s synthetic blend ensures that oil doesn’t thicken as much, even after a long overnight drain, while Valvoline, being a synthetic blend, faces more challenges in that area.
Film Strength and Protection
Another key area where AMSOIL shines is in its film strength. This refers to the ability of the oil to form a protective layer between moving engine parts, preventing metal-to-metal contact. AMSOIL’s Signature Series oil is designed to provide top-tier protection for up to 25,000 miles. The film strength in AMSOIL is particularly strong, offering better protection against wear and tear than some other oils.
On the other hand, Valvoline, while not necessarily inferior, offers a slightly shorter recommended oil change interval, generally around 10,000 to 15,000 miles, depending on driving conditions. This may be more than enough for most drivers, but if you want something that’ll go the distance with less frequent oil changes, AMSOIL might be the way to go.
Additives and Performance
When comparing AMSOIL vs. Valvoline, the additives make a big difference. Additives help improve oil performance. They reduce friction and keep your engine clean.
AMSOIL Signature Series uses top-quality additives. These include detergents, dispersants, and anti-wear agents. These additives help prevent sludge build-up. If you drive in tough conditions or take long trips, AMSOIL can keep your engine cleaner for longer. It’s known for cleaning power, which is great for engine health.
Valvoline also has quality additives. Its oil is made to protect against wear and clean the engine. Valvoline’s High Mileage oil has seal conditioners. These help stop leaks in older engines. If you drive a higher-mileage vehicle, this could be a good choice. But, Valvoline doesn’t have the same extreme performance as AMSOIL, especially in tough driving conditions.
Price and Value
Price is always important when choosing motor oil. AMSOIL is a premium product. It costs more upfront, but the benefits can make up for the cost. If you plan to change your oil less often or drive in harsh conditions, AMSOIL might save you money in the long run.
Valvoline is more affordable. It offers solid performance without the high price tag. For most everyday drivers, Valvoline works well. If you stick to regular oil changes, Valvoline can provide great value without the extra cost of AMSOIL.
Ease of Use and Availability
One thing you’ll notice with both AMSOIL and Valvoline is how easy it is to find them. Valvoline is everywhere. You’ll see it at most auto parts stores and even big-box retailers. It’s the oil that’s most accessible for the average person, which makes it super convenient. If you run out of oil or need it fast, Valvoline is the go-to.
AMSOIL is a little different. It’s not as easy to find in regular stores. You usually need to order it online or find a local dealer. This can be a hassle if you need oil in a hurry. However, AMSOIL’s direct-to-consumer model means you can often get a good deal on bulk purchases. If you’re willing to wait or plan ahead, it’s a solid choice.
Longevity and Oil Change Intervals
When it comes to how long these oils last before you need a change, AMSOIL generally lasts longer. It’s designed to handle up to 25,000 miles between changes, depending on driving conditions. On the other hand, Valvoline’s oils typically need to be changed every 3,000 to 7,500 miles, which is shorter. This difference is mainly due to AMSOIL’s advanced synthetic formula, which provides more protection over a longer period.
AMSOIL and Valvoline both offer excellent protection for your engine, but they stand out in different ways when it comes to how often you need to change your oil.
AMSOIL Signature Series is famous for its long oil change intervals. Depending on your driving habits, it can go up to 25,000 miles between changes. That’s a lot less hassle and fewer trips to the mechanic. If you do a lot of long highway drives, AMSOIL’s extended drain intervals could save you both time and money in the long run.
Valvoline, on the other hand, typically recommends more frequent oil changes. Their oils usually go around 3,000 to 5,000 miles before needing a change, depending on the type. For regular drivers, this isn’t a big issue. But if you drive long distances or want to stretch your oil change schedule, AMSOIL might be the better choice.
| Feature | AMSOIL | Valvoline |
| Oil Change Interval | Up to 25,000 miles | 3,000 – 7,500 miles |
| Longevity | Very long-lasting | Good for regular use |

Price and Value
Price plays a big part in your decision. Valvoline is usually more affordable, making it a great choice for people who are on a budget or don’t mind changing their oil more often. AMSOIL, however, comes with a higher price tag. But, you’re paying for longer oil change intervals and top-tier protection, which can save money in the long run by reducing maintenance frequency.
There’s a clear price difference between AMSOIL and Valvoline. Valvoline is the more affordable choice. It’s great if you want something quick and budget-friendly. You can find it at most stores without spending too much. If you don’t mind changing your oil a little more often, Valvoline gives you good value.
AMSOIL costs more. But it offers longer oil change intervals and better technology. This makes the higher price worth it for some people. If you care about performance and want fewer oil changes, AMSOIL is a solid choice.
To sum it up: Valvoline gives you value at a lower price. AMSOIL gives you long-term value with fewer oil changes and better performance.
