Are you searching for an answer to the question: Is all oil the same? On this page, we've collected the most accurate and complete information to ensure that you have all of the answers you need. So keep reading!

When it comes to choosing engine oil for your car, you might think “it's just oil, surely they're all the same?” Not only are there different types of oil, but they also differ in viscosity and additives which can have a significant impact on the performance and life of your engine.

You may wonder, is there a difference in brands of oil? Less expensive motor oil is less expensive due to the lower quality of its chemical makeup. Off-brand oils are full of harmful fillers that will end up doing more harm than good in the long run. That's why it's important to choose a high-quality motor oil for top engine performance.

Similarly one may ask, is every car oil the same? Engine oils aren't all the same. You can't assume that the same oil you used for your last car will work for this one. So if you need to top-up, make sure you use the right grade and specification.

Besides above, do all brands have the same quality of oil? The reason is that every brand of engine oil is formulated differently, especially with regard to the additives used by its manufacturer. Nobody, possibly except for the top scientists and engineers working in these oil firms, knows the chemistry of their engine oils.

Likewise, is it ok to mix oil brands? 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 I change oil every 2 years?

Simply put, as a general rule, manufacturers recommend that you change the oil for a gasoline engine every 10,000 to 15,000 km, or about once a year for “regular” usage (frequent but not intensive) or once every 2 years if used less frequently.

What's the difference between 100% synthetic and full synthetic?

Defining “100% Synthetic” & “Full Synthetic”

Some define “100% synthetic” as motor oil made exclusively from Group IV polyalphaolefin (PAO) base oils. In contrast, they define “full synthetic” as an oil made from Group III base oils.

How often should you change your oil?

between 7,500 to 10,000 milesAnd while the old rule of thumb was to change your oil every 3,000 miles or so, modern automotive technology has stretched that figure even further. Due to better engineering and better oil formulations, now you can expect between 7,500 to 10,000 miles between oil changes!

Does it matter what oil I put in my car?

The most important thing is to use oil that's the right thickness, or viscosity, for your car's engine. Oil that's too thick or thin won't provide the necessary protection for your engine, which can result in costly damage.

What happens if I put the wrong oil in my car?

Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won't harm the engine, but there's also no benefit in doing so.

Can I use any 5W30 oil in my car?

In short: Every manufacturer has its own engines with its own specifications. As a result, every engine needs its own specific 5W30 oil. However, some 5W30 oils can be used for multiple brands.

Is some motor oil better than others?

Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can't compete with the overall engine performance and protection provided by synthetics.

Does full synthetic oil last longer?

Does synthetic oil last longer than conventional oil? In general, yes, synthetic motor oil provides longer intervals between oil changes, but it depends on the brand of oil you use. Certain brands recommend you have your oil changed every 3000 or 5000 miles. Other recommendations range from 7500 to 20,000 miles.

Can I mix 2 different synthetic oils?

In general it is never a good idea to mix two different oils in any application. If this is unavoidable, there are two major concerns, specifically incompatibility between the base oil, and incompatibility between the additives. The overwhelming majority of synthetic oils, particularly crankcase oils are PAO based.

Does it matter which oil brand you use?

As long as the oil weight and certifications match what your car needs, there is no point in paying extra for a brand name. Blackstone Laboratories has performed oil analysis on hundreds of thousands of vehicles.

Is some motor oil better than others?

Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can't compete with the overall engine performance and protection provided by synthetics.

What happens if you mix car oil brands?

As long as both oils have the same weight (or viscosity) rating as recommended in your owner's manual, you can theoretically mix engine oil brands without damaging your engine. While there may be some slight differences across motor oil brands, the base mixture of oil and additives will be more or less the same.
