good possibilities for aftermarket oil filters, i've ordered a subaru impreza HKS oil filter. i'm going to verify wether or not the filter itself will fit. the lip seal is what will make or break the deal, fingers crossed. this could be seriously cool

Considering the HKS Oil Filter Id definitely be careful of the seals from what I hear

 

[oscar]

what do you mean? i've not heard anything bad about the seals, worked a treat on my old new age

the hybrid system has magnets inside, the TCE being a full flow system would mean that all the oil will be filtered in two different ways.

1 - normal 10-20 micron filtration using corrugated paper.
2 - a second magnetic filtration, picking up small particles of metal that are otherwise suspended in the oil film.

more of an experiment to see what is possible, but i'd be much happier with that than i would your usual style oil filter! you could always stick a magnet to your £4 motor factor oil filter i suppose for hybrid bragging rights, but that would defeat the purpose.

Aftermarket filters are always a bit of a difficult decision, I would say stick with the genuine OEM filter, take a look at the link, I know it's Toyota but the principal is the same https://www.mr2roc.org/phpBB3/viewtopic.php?f=46&t=21233

Probably says there prone to leaking

The thick square section seals found on most OE filters generally seal very well against moderate pressure, even on slightly uneven surfaces as theres enough rubber thickness and width to cover any irregularities.

O-ring seals tend to be thinner and will give a better seal... if the surface its sealing against is clean and flat. So, attention to detail is going to be needed to ensure all the face is cleaned properly, compared to OE where a quick wipe and throw it on is enough.

 

[oscar]

the idea will be to see if the OE seal would fit into the HKS if not, i want to see if it fits. i know that the inner dimensions will vary, seal thickness and whatnot. HKS don't actually make the filter, it's Nippon-Denso. wouldn't say they're prone to chucking out crappy air filters, and aftermarket air filters are pretty damm good rob. framm for example make all of fords filters, mazda, honda, kia and a good few others but on a renault they're considered aftermarket lol. they are also the darlings of halfords

Note: Not all of these filters are available in the UK. Some are probably sold under other names as well.


One day I was bored at work as usual and I remembered I was way past due my 3k oil change. Rather than using the search like I was supposed to, I was just too lazy (maybe its from the food coma at lunch) and started a thread that I knew probably already existed. After a few post I got an earful from Dev about Spyderchat morale standards and blah blah blah. So afterwards I started searching and searching and it was basically peoples recommendations on the big fancy oil filter names. I also a did a little research on this this website https://www.knizefamily.net/minimopar/oilfilters/toyota.html and learned something about it. Maybe the website was way too technical for me but my question was still unanswered. Whats a good oil filter for my spyder?

So I ordered this oil filter cutting tool.

Also went out and bought 9 MR2 Spyder oil filters.

1. TRD $14
2. Fram $7
3. Toyota OEM $8
4. ACDELCO $4
5. STP $5
6. Pennzoil $5
7. K&N $10
8. Mobil1 $10
9. Bosch $6

After opening these oil filters up I noticed that basically some are the same filters that are rebadged. The first 2 are identical. FRAM and Pennzoil. The dreaded cardboard that everyone talks about is holding the paper filter together. The filter material is very dark brown very rough and hard almost like cardboard itself. Yes even these cheapo filters have anti bypass valve. They ALL do.

The next 2 is STP and Acdelco. Again both are identical, but wait Adelco is made with better paper material which is softer where the STP is similar one on the Fram and Pennzoil.

Here we go with the big boys. Everyones favorite performance oil filters. K&N and Mobil1. Again the are the SAME oil filter with a nut on the K&N for easy removal with a socket. What is so special about these expensive oil filters? I really dont know. Then something caught my eye.

I went back and grabbed the STP filter and compared it to the K&N. Could you find the difference? I cant. The nitrile rubber gaskets are the same just different color. 5 dollar filter and 10 dollar filter are the same.

Here is one of the oil filters Ive always used on my car. Bosch has some what of a different design than the other filter. The anti bypass valve is a coil of metal rather than a spring. Of all the filters Ive opened up, this has the MOST paper fins. The whole material is wrapped tight. I guess Ive made the right choice the filter in my eyes looks very well designed.

Here is the Toyota OEM. The biggest filter in the pack. When set side to side with other filters its about an 1 inch to 1 1/2 taller than the other filters. This by far has the most paper filter on it. The paper is very different from the others. It soft yet dense with volume. It also has a plastic seal seal on it before us. Very fancy!

And finally the TRD. The most expensive filter money can buy on your spyder. The most noticeable element of this filter is the material. The paper material is thick and soft almost like like cotton fabric itself. The anti bypass valve is also internal. TRD advertise that the bypass system is made for high rpm engines and not just for cold starts.

So after opening up all these filters and seeing with my own eyes what did I conclude?

Dont buy fram or pennzoil.
K&N and Mobil1 is NOT worth the $10.
STP is the same thing as the high performance advertise oil fitlers, but at 5 bucks which came out to the biggest oil shocker for me.
AcDelco is average maybe less than average.
Bosch(Purolator) is a solid design and great for its price.
Toyota OEM is a great filter. I bought a case of 10 for 5 bucks each at Twos R Us. You cannot go wrong with oem.
TRD for 14 bucks and fancy paper material is unknown to me. Unless I have a crazy rev happy engine I would not spend 14 bucks on an oil filter. Maybe I'm just cheap.

If you guys have anymore questions on what else to look for on these filters before I throw them all away feel free to ask away. Hate to throw away 70 bucks in unused oil filters.

I hope this works, makes interesting reading.

Rob.

 

[oscar]

very interesting read rob i won't lie, but you just shot yourself in the foot. purflux / fram / champion make renault OEM oil filters. your post states avoid fram like the plague but your recommendation is to stay OEM with oil filters?


what's it going to be ... lol

i've always preferred nippon-denso / purolator / wix. that's the main reason why i wan't to see if the HKS subaru will work rob, knowing that it's a re-badged nippon-denso with the added function of a secondary magnetic filter to catch suspended metallic particles will make me feel a lot better knowing that my TCE engine is now getting on a bit at 60,000 miles. plus i'm a brand whore, no shame in admitting that.

50 % brand whore
50 % curiosity to see what can be done. after all, the concept behind my 'jap' theme is to take parts from other cars and see what i can make fit!


edit - the more i think about it, the actual softness / hardness of the filtration material cannot be judged by how it feels or looks. good filtration requires a large surface area combined with the correct filtration, usually measured at a micron level. logic would surely state that this chap's got his heart in the right place, but his head's a bit up his backside. would you not think that it would be a good idea to do the same experiment after 3,000 miles to see the state of each filter? seeing as though it's an oil filter, and not a paris catwalk ?

Hi Oscar.

It's not my thread, I certainly wouldn't have cut up that many filters :shock: it was completed in the US but makes more reasoning to stick with the OEM brand. Although Fram etc make for Renault it will be to their spec not Fram's own.

I couldn't really use any other but Renault as the car is still under warranty.

 

[oscar]

i know it's not your thread lol. it was still a good read, but i spotted the mistake from the off. it's a filter, not a work of art. doesn't matter too much if this company or that company adopt different materials for oil filtration, what you want to judge it on is how well it filters the oil and how long it lasts between services. a larger surface area will provide you with a longer service life in theory assuming regular service intervals are adhered to.

with my subaru, i noticed that nippon-denso made the best filters providing the largest surface area. that meant that i could extend the service period between oil changes from 6,000 to 8-10,000 miles, of which i was doing 1,500 miles per month. ever since the subaru went and i got the GT i wanted to see if i could get a nippon-denso but i never would have thought there would be a possibility that a subaru oil filter etc could possibly fit onto a renault because lets be honest, the concept of that is just mad ... yet realistically, it somehow appears perfectly possible that it may fit.

or i could end up with a facial of engine oil as i'm under it whilst my mate cranks the engine > oil filter blows off and i crawl out the engine looking as black as a shadow lol

Filters work in either of two ways:-
Sieve /strainer type, which has a mesh tight enough to prevent particles passing through if their size is greater than the filter rating. Here, the particles will be mostly trapped on the surface of the filter.

Labyrinth / depth type, which is good for filtering longer particles as they become trapped within the depths of the filter as has to take a zigzag route through.

Chances are that most of the metal particles will be relatively long thin particles, shaved from bearing surfaces or cylinder bores. If we look at a long thin particle which has a hypothetical size of 1micron diameter and 5micron in length...
A. a strainer type filter would need to have <1micron sized holes to prevent them passing through. However, that would even cover shorter lengths or longer lengths too. The drawbach is, such a tight filter will create a greater pressure differential across it so theres greater chance of the bypass opening.
B. The labyrinth element can have a more open weave which would allow the particle through if it was shorter. However, the longer partices become ensnared like a lorry trying to get through a slalom
