THE ANSWER IS NO! Even if two different brands of oil have the same viscosity, you still should not be mixing them together.
Can you change synthetic oil brands?
No, you can safely mix different synthetic brands. So, can you change synthetic oil brands? Most synthetic oil manufacturers state it is acceptable to replace synthetic oil with another brand or mix different brands. However, ensure you do not mix different synthetic brands with different oil viscosity.
Can you mix synthetic and conventional oil?
Yes, you can safely mix one brand of oil (e.g. Mobil 1) with a different brand (e.g. AMSOIL) or conventional oil with synthetic oil (in fact, that’s what a synthetic blend is). Most synthetics today are fully compatible with conventional oils and can safely be mixed. Can you mix synthetic and fully synthetic?
Can you mix motor oil?
Therefore, you can safely mix one motor oil brand (e.g. Castro) with a different brand (e.g. Valvoline). You can also mix synthetic oil with conventional oil. In fact, semi-synthetic oil is a blend of fully synthetic and conventional oil.
Is it bad to mix engine oil brands?
Mixing oil brands isn’t necessarily bad, but brand manufacturers do not recommend it. Each brand has proprietary additives to its formula and will interact with other brands differently. Mixing engine oil is always better than driving a car with depleted oil or dirty engine oil.
What are the disadvantages of synthetic oil?
A few disadvantages of synthetic oil to be aware of include: Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.
What are the disadvantages of synthetic motor oil?
Disadvantages of Synthetic Motor Oil Many of the synthetic oil blends reduce friction better than conventional motor oil. This was a problem with a new engine break in period. Synthetic oil does not hold lead in the suspension of the oil. This is a problem with older car engines that still need leaded gasoline to run in their engines.
Is synthetic oil better than conventional oil?
Likewise, synthetic oil’s longer lifecycle versus conventional oil has also attracted many, with conventional oil requiring changes every 3,000-5,000 miles and synthetic every 7,500-15,000 miles.
What is the engineering of synthetic oil?
Engineering of synthetic oil flows along the same concept. Synthetic oil manufactures draw its components from the best compounds and molecules of the crude oil. That is why synthetic oil is a better preference for most motor engines. However, it comes with a bag full of advantages and a small volume of disadvantages too.
Is synthetic oil safe for high mileage engines?
Synthetic oil actually flows easily so it is not recommended for use on those high mileage engines. It is also not recommended for use on vehicles or engines during their break-in periods due to the fact that it is highly slippery and it is limiting the wearing of those new matting parts inside the engine.
Can car oil last 2 years?
Simply put, the shelf life of conventional motor or “lube” oil is up to five years. It’s not something that goes bad in a couple of months. It’s impossible to predict exactly how long motor oil shelf life is because petroleum stability (how well it resists change in its properties) is situation-dependent.
How long does motor oil last?
The motor oil’s shelf life recommended by each manufacturer varies, though. For example, Mobil expects industrial or motor oils to last for five years if stored properly in the original container. Meanwhile, Total, another leading manufacturer, says motor oil should be disposed of after only two years if not used.
Does engine oil go bad after sitting unused?

What does W mean in lubricant?
The “w” stands for winter and indicates that the lubricant in question has a different viscosity, or different flow characteristics, based on temperature. For example, a 5w30 oil weight rating means that on cold start-up — even at subzero temperatures — the oil flows like a 5 weight oil.
What is 5W-30 motor oil?
5W-30 motor oil is a type of oil that is used in many modern vehicles. The “W” stands for winter, and the “30” stands for the oil’s viscosity, or how thick it is. Viscosity is measured at two different temperatures, cold and hot. The first number, 5 in this case, corresponds to the oil’s viscosity at cold temperatures.
What does the number in engine oil mean?
The numbers in oil signify the oil’s viscosity or thickness. The lower the number, the thinner the oil and the easier it flows. The higher the number, the thicker the oil and the slower it flows. All oils have a certain degree of viscosity, which is affected by temperature. When it’s cold outside, your motor oil thickens and doesn’t flow as easily.
What is oil weight?
Oil weight is a term used to describe the viscosity of an oil, which means how well it flows at a specific temperature. The Society of Automotive Engineers (SAE) assigns a viscosity number, or weight, to oil based on its flow at 210 degrees F, which is roughly the standard operating temperature for most motors.
Does engine oil brand matter?
The Effects of Low Quality Motor Oil Whether you choose to change your car’s oil with a bargain brand or a brand you trust, both choices will have immediate and long-term effects on your vehicle.
