Can two lubricants be mixed together in the same engine?


With the concern of mixing lubricating oils together is a thought of many. Let’s put some light on this thinking. Here, we are going to analyze concerns of mixing different lubricating oils to make them more efficient and multiply their benefits. This way, you can replenish your ride and get an optimized ride with much-needed benefits.

If you are planning to mix oils from two different brands either with same viscosity of with different viscosities, it is better you should not be mixing them together. Because this might reduce their efficiencies on a broader way but it might benefit you more with some of expert’s advice. More precisely and technically, using a grade or viscosity of oil that is recommended by your car manufacturer is the way that will keep you safe and keep your smooth running possible. To some, if you are thinking about combining two different brands of motor oil, you might put your car at risk of damage.

You might be thinking why it is not recommended to mix oils from different manufacturers. The reason might be that every manufacturer of engine oil formulate its brand and oils with different processes and different specialties. There might be a difference in formula that is used in oil manufacturing. There might be a difference with regard to the additives used by every manufacturer. Therefore, every brand oil might offer you different benefits and different offerings.

Exact formula

There is a possibility that except the top scientists and engineers working in lubricating oil manufacturing firms might not know the exact formula or chemistry of those engine oils. Therefore, being a consumers we might not be sure that the lubricating oil from one brand does not affect the oil from another brand. So, there is always a risk in mixing those oils together. You might end up ruining your engine.

To some, there might not have any problem with the idea of mixing different lubricating oils. The idea of mixing different viscosities or even different brands, or the idea of mixing synthetic oils with mineral oils. It is done all the time and with more frequent ways to boost up your benefits. Let’s view and highlight their perspectives.

There are traces of oils left in your engine, as 15 to 20% of the old oil stays in your engine with every oil change. With this fact, whenever you change your car’s oil, there might be a mixing of different brands or different viscosities, or there might happen a change to synthetic or to mineral oils. So, this mixing scenario might be happening everywhere and every now and then. But it doesn’t harm your engine at all. So, the idea of not getting it mixed is nothing but a joke.

To them or to most of advocates of mixing oils, there might be no reality or no wisdom lies in not mixing oils together. They might not get the point that why people forbade to mix two different viscosities or two different brands. This mix might end up something in between those two parent oils. With another fact, if someone is consuming too much 5W-20 viscosity range, it is better and recommend as well to use a 10W-30 for the replenishing cause. So, it might be no harm in mixing different oils together and build a new one with more benefits and more offerings.
