🥇 5 Best Oil Filter Bob Is The Oil Guy Of 2021 – Reviewed & Tested

99.6% Multi-pass efficiency rating.

28.0 grams holding capacity.

Exceptional protection up to 615 pascals per square inch.

Silicone anti-drain back valve.

Firstly, the efficiency oil filter rating is really good in Mobil 1 auto filter. It is capable of sieving out 99.6% of the contaminants in the oil before it passes into the engine. This is particularly aided by the synthetic fiber-blend media incorporated in the filter. Synthetic media, in general, are a level above the cellulose ones in filtering out the dirt. They have far more consistent pores and are relatively more reliable when it comes to the smaller impurities.

Another advantage of this synthetic media is the extended holding capacity that this fuel filter offers. It can hold up to 28.0 grams of filtered contaminant. Just make sure that you change the oil filter when you go for your next oil refill.

It works just as well with any kind of motor oil. It is not necessary for you to stick to Mobil ones. That’s an advantage on the go when you don’t have a choice of motor oil.

Mobil 1 is the most appropriate oil filter for 100% synthetic motor oil with 615 PSI operating pressure. This is almost nine times the pressure than any other oil filter can withstand.

It even has an oil filters with anti drain back valve . This removes the probability of internal leakage. You will suffer from fewer dry starts this way.

Honestly, this is one of the few products where I can’t possibly see any flaws. It is great on all levels, and I have tried out quite a few of these.

Thicker shell.

Metal end caps.

100% screen-back synthetic media.

Heavy gauge steel backplate.

I have been through a couple of issues with road debris punctures. This oil filter solved that for me. Its thicker shell is built to provide an extra level of protection that won’t be accessed by any random dirt particles. Another advantage this provides is the higher resistance to internal pressure.

The caps are made of metal as well. This is built to ensure a positive seal for the element assembly.

Moving on, this has a pure synthetic media. This basically means near-perfect filtration of all impurities. However, it does not deter the oil flow at all. It can easily hit a 99% efficiency rate. This is almost as good as the Mobil auto filter efficiency. It halts impurities as minuscule as 25 microns, which means that there is a very low possibility of dirt seeping through.

If ever there is a case of flow restriction, there is a cop-out for that as well. The by-pass valve ensures the possibility of lower oil flow in those situations.

The steel backplate, on the other hand, enhances the burst strength further.

There is a silicone anti-drain valve here too. So you won’t have internal leakages and dry starts either. Silicone is actually better than nitrile rubber. It survives extreme temperature far better.

Functionally, it has little to no flaws. However, this is not always my first choice. You can get a product as good as this one, at a lower rate.

Exclusive FILTECH Media Technology.

Silicone anti-drain black valve.

High lubricity gasket design.

Double-locked rolled seam.

The FILTECH technology in the media of the oil filter is the most prominent feature here. It serves as advanced engine security by filtering out the impurities. However, the media here is unique. It is not pure synthetic but a better version of it. A blend of natural and synthetic components ensures a better filtration and protects the engine. The oil filter is a bigger one as well. The area is at least 42% larger than any other product. A thicker media by around 30% can filter out the more persistent impurities as well.

It is further equipped with enforced steel-based plates. These serve to prevent warpage and more importantly leakage. It has an added perk as well. It, to some extent, prevents a poor fit of the oil filter itself.

The silicone anti-drain valve again is a superior component compared to rubber ones. It serves against leakage and provides a flow of clean oil when you start the engine. It again prevents dry starts as well.

The Double-locked rolled seam again provides a leak-free canister.

However, on the downside, it has a relatively lower contaminant holding capacity. Compared to the Mobil and Royal Purple oil Filters, this is a really disappointing feature.

98% filtration efficiency.

Cellulose media.

Thermosetting Adhesive Seal.

Enhanced Durability.

While the filtering efficiency is exceptional, I would like to start with a unique feature of this filter among the others in this list: the media composition. It is not synthetic like the other three but a cellulose one. This gave me a bit of a pause when I initially looked it up, but then, I decided to give it a go. And I am glad that I did. The pores are tiny enough to block contaminants with a width that is a third of a human hair. Cellulose media are often looked down upon due to inconsistent pores and lower filtration, but this one was impressive.

And that brings us to the filtration efficiency. A 98% filtration rate is nothing to scoff at. Sure some others in this list have a higher rating, but still, this is pretty good. It has a rate of 25 to 30 microns to be exact, in its filtration capacity.

The thermosetting adhesive seal, on the other hand, is really useful here. It fixes the media in its place so that the filtration is not affected by any movement. This serves for a clean and consistent oil pumping into the engine.

The burst strength is five times what an average filter has. It can handle the oil at its operating temperature below 51 PSI. The major flaw is that Royal Purple is specifically diesel oil filter and that is kind of restrictive. Apart from that, it is a bit above my range as well. But if I have a diesel vehicle, I can definitely overlook that bit for the rest of the advantages.

5000 miles protection used with Conventional Oil

It is best synthetic oil filter with 95% Filtration capacity.

I will begin with the filtration efficiency as that is it’s the most prominent feature. It has a truly superior one too at a solid 95%. While compared to the other, it might seem low, but considering the range, it is very good.

However, that does come with a disadvantage. You might have to sacrifice on a long-lasting filter if you want the superior dirt filtering feature. It works well till 5000 miles, which is kind of low. So you might have to change your filter and your oil a bit more frequently.

This can be used with conventional oil or gasoline. The filter is capable enough to handle regular oil pressure.

For a disadvantage, I might go with the low life-span. So if you can invest time for frequent changes, this is really good at a very affordable rate.
