Mobil Synthetic Oil Filter

Mobil Synthetic Oil Filter

The first on our list of the best oil filters is this highly popular filter by Mobil. One of the key aspects that caught our attention regarding it was the incredibly high consumer ratings it boasted on Amazon. After reading through the numerous customer reviews we saw there, we thought that two things kept lingering- a majority of users praised it for its efficiency and durability. A physical assessment later showed that these approvals originated from the smart and precise design this filter by Mobil featured.

Its sieve, for example, is made using a synthetic fiber that boasts over 99.6 percent efficiency rating. This helps it stretch its holding capacity to double what most other conventional oil filters can; to be precise, a little over 28 grams of contaminants.

However, its most outstanding feature lies in its robust nature in the face of pressure. Mobil filter can weather up to nine times the normal operating pressure of the engine without letting loose a leak. How commendable is that?

Also, notably, this oil filter comes with a silicone anti-drain back valve that helps safeguard your motor’s engine from dry starts. This is key in averting common leakage that often occurs during engine shutdown.

Buyer Guide- Best Oil Filter for Synthetic Oil

Like anything else, engine oil comes in different flavors and varieties with each having its strengths and weaknesses. Some quick research around the motor industry reveals that the popularity of synthetic oil is growing at a very quick pace as more users understand the numerous benefits it boasts over its conventional counterpart. Not only does this oil type last longer but is also fully compatible with nearly all modern oil filters. What is even more impressive about it is its high capacity to capture contaminants without clogging the oil filter. Simply put, it’s truly a magical supplement.

So, have you switched to using synthetic oil and are looking for an appropriate oil filter for your engine? Here’s a comprehensive buyer guide to help you purchase only the best. Before that, though, let’s take a look at the top three most popular types of oil filters you can find today;

Types of Engine Oil Filters

The best oil filters will eliminate over 99% of impurities during the first quarter of using them. However, as they age, their sieving membranes obviously begin wearing out and thus permit waste back to the mechanical parts. All in all, the one key aspect that determines their durability is the nature of the filtering media/membrane. Here are some of the most popular ones:

  • Synthetic Oil Filter

This is definitely our favorite oil filter. What we love the most about this type is that it works comfortably with both conventional and synthetic oils. It’s resistant to higher temperatures and traps on average over 90% of oil impurities during its lifespan. The main reason behind this incredible level of efficacy is due to its restrictive membrane which filters out any particle bigger than 20 microns. Oil can thus remain in its optimal viscosity despite high mileage. Synthetic oil filters work best with oils capable of dissolving grunge.

  • Cellulose Oil Filter   

The media embedded in this filter is thicker. As such, cellulose oil filters tend to be ideal for engines running on diesel which contain waste substances of all sizes. Due to their thorough filtration, these filters often have shorter lifespans. It can cover about 3000 miles before demanding a replacement

  • MicroGlass Oil Filter

This one has compact sieves and is comparatively thinner than the two other types discussed above. It is permissive to impurities smaller than 30 microns and can go for over 10000 miles when fitted in engines using gasoline for fuel. However, the only key setback about MicroGlass filters is that they are a bit more expensive while their spares are quite rare to find.

Benefits of Using the Best Synthetic Oil Filters

  • Saves you money

No one wants an engine that stalls every few weeks. What a majority of car owners don’t know, however, is that it all begins with tiny routines such as swapping conventional oil filters with high-quality ones. And while at it, remember that even these will last even longer when combined with the use of synthetic oils.

  • Improves the performance of your engine

Want to enjoy more service from your car engine? Then do not compromise on the quality of key parts such as oil filter. Remember that moving parts will require lubrication frequently and also work best under optimal temperatures. Luckily for you, we’ve reviewed the best synthetic oil filters to help you achieve this quite seamlessly.

  • More mileage

Long distance travelers adore vehicles that travel longer with zero glitches along the way. An ordinary oil filter will hardly deliver this to you. Only the best will give you actual value for your money. Why not fit one such today?

Factors to Consider when Buying the Best Oil Filter

  • Durability

The longer your oil filter can last, the lesser the money you’ll spend on maintaining your car in the end. For this reason, it is recommended for you to avoid filters that use poor-quality materials such as paper. Instead, go for any of the five best oil filters for synthetic oil described in the earlier section.

  • Compatibility

Technology is evolving fast. To be part of the movement, it is crucial for you to always equip yourself with spare parts that are compatible with your engine. From research, engine manufacturers are now constantly advocating for use of synthetic oil which serves the mechanical parts much better. In addition, this oil types also works best with synthetic oil sieves which as we have seen come with a myriad of benefits.

  • Toleration to high temperatures

You do not want an oil filter that fails when you need it the most. Rather, you want a resilient tool that’s capable of handling the heat with the composure of a pro. Conventional oil filters will burn out during high temperatures. Avoid this kind of frustration by choosing one from our list of the best oil filter for synthetic oil.

What Affects the Life Span of Synthetic Oil Filters?

  • Nature of your engine

Engines powered by turbo have higher throughput and spin speeds. This increases chamber temperatures which in turn causes the oil to break down into its constituent elements including carbon. Eventually, this affects the quality of your oil by increasing its viscosity and reducing its lubrication capacity. Grunge which would otherwise dissolve in oil clogs your car’s oil filters thereby interfering with their ability to sieve particles.

  • Fuel type

If you use gasoline or petrol, your oil cleaner will almost always serve you dependably past the bare minimum limit of 7000 miles. However, heavy fuels such as diesel produce acidic waste products. These wastes then corrode the surface of the combustion chamber which could trigger leakages of dirt and soot to the crankcase. As a result, this damages the quality of oil which in turn ages your oil filter much faster.

  • Quality of your oil filter

Unless you’re riding your beast while fitted with the best oil filter, your servicing and maintenance costs will certainly skyrocket. Remember, this is the crucial element that sieves all those nasty stuff from reaching your engine’s lubrication segment and preventing your engine from aging or malfunctioning.

  • Season

Cold seasons such as winter reduce oil’s optimal working temperature. This, in turn, allows combustion byproducts to clog the oil holding area. When warmer seasons return, or during long trips, most of the trapped dirt and dust is pumped back to the oil filter thereby subduing its purifying capacity.

  • Age of your Engine

This is possibly a rule of thumb- the older the engine, the higher the chances of natural wear and tear. Particles from worn out parts end up flooding your oil before blocking the sieving pores and finally rendering your oil filter useless.
