Flaws We Found: The biggest flaws in this filter are the lack of a bypass valve and the cheaply manufactured cartridge. Sadly, neither of these things make this the worse filter of the bunch.
The SuperTech filter does technically have a bypass valve. Sort of. If the pressure in the canister is high enough, the pressure on incoming oil will push the anti-drainback valve back, which will push the cartridge back, which will flex the spring at the end of the canister and create a bypass. The concern with this type of design is that either a it won't work very well, and the engine will be starved for oil at W.
Still, the SuperTech isn't the only filter without a "real" bypass valve. The ACDelco filter uses the same cheap setup, and in all fairness, the more expensive filters utilize a similar principle Verdict: Considering the price and the fact that it's not the worst filter we looked at, it's not terrible.
But it's definitely not the number one option here either. General Observations: The most notable difference between the OEM filter and all the others is the size - the Toyota filter has both the longest canister body and the biggest cartridge - in terms of outer diameter, length, and pleat depth.
This means the OEM filter media has the largest surface area of any filter we looked at - nearly twice as big as many competitors, in fact. Another big difference is that the OEM filter cartridge doesn't have any end caps. Unlike the competing filters all of which use either a metal or fiber endcap to hold pleats , the entire filter surface would seem to be usable. In order to keep oil from slipping past the ends of the filter cartridge, there's a metal sleeve that attaches to the anti-drainback valve on one end and the bypass valve on the other.
Additionally, each end of the pleats is glued together. When you look at the microscopic views, it's pretty clear that Toyota's filter medium is more fabric-like than the others, and this was also noticed when we cut out some filter material. The Toyota filter material is definitely the sturdiest of all the filters we took apart, but it's unknown if that's a good thing it may have no impact.
Finally, in keeping with the tenets of the Toyota production system , the specs on the OEM filters we tested matched up almost exactly. Flaws We Found: First, the cartridge has a "super pleat" on the filter medium seam - two different pleats are glued together note: superpleats are counted as one pleat rather than two. Second, the open ends mean that, if some of the glue holding the pleat ends together wasn't applied correctly, oil would be able to sneak by without filtration.
Of course, this assumes that they aren't glued properly, and that wasn't something we saw in the filter we took apart.
Verdict: There's no denying that the size of this filter results in better engine cooling ability and, in all likelihood, high filter flow rates perhaps the highest. Toyota uses a fairly inexpensive-looking bypass valve, but we think it's safe to assume this valve is adequate. Considering the low price of the OEM filter when compared to all the other filters we looked at, the OEM filter seems like a very good value.
General Observations: Wix filters generally perform well in Internet oil filter comparisons like this one see notes section for some links.
This comparison is no different - the Wix has a very solid combination of a quality anti-drainback valve red silicone rubber and a cleverly designed bypass valve.
When the external pressure on this o-ring is high enough, it compresses the spring and opens up a gap that oil can flow through right near the front of the canister. This type of bypass valve would seem to be the most expensive, mostly because it requires more assembly and greater manufacturing tolerances than the plunger-type design used on the OEM filter or at least that's our opinion. Of all the filters we looked at, the filter medium used in the Wix most closely resembles the filter medium in the OEM filter.
This would seem to be a good thing, as the OEM filter material was definitely the sturdiest of the bunch. While sturdy filter material might not matter much, it seems logical that stronger filter fibers hold up better during prolonged filter use. Combined with metal endcaps, this seems like a very sturdy filter. One other note: The metal sleeve inside the Wix has a large spiral groove that supposedly increase flow rate Fluids flow in what is called a 'no-slip' condition, which means that spiraling the inside of a filter isn't going to have nearly as much impact on flow as spiraling the inside of a gun barrel has on the speed and stability of a bullet.
According to an interview we did on TundraHeadquarters. Flaws We Found: The metal end caps on the filter cartridge present two problems. First, the pleat spacing is pretty uneven Additionally, the end caps are 7mm tall, and the filter medium that sits inside each cap probably doesn't flow a lot of oil.
The other area of concern is that the Wix filter medium is both thin second thinnest in our comparison and low density when compared to the OEM material. Again, if we assume that the OEM filter meets or exceeds all of Toyota's minimum requirements, we have to wonder about filters that would seem to do less filtration Verdict: The problems with the Wix filter are the uneven pleat spacing, the thinner and lighter filter material, and the thick end caps that decrease the effective surface area.
The strong points are that the Wix still has the second-largest surface area, a quality anti-drainback valve, and a very clever bypass valve. Despite the uneven pleats, the Wix filter's beta ratios are solid and it definitely seems like a good choice.
General Observations: Before we cracked open the canister and really started looking over the innards, the Bosch filter was off to a good start.
The cartridge end caps are metal, the anti-drainback valve seems to be of good quality, and the total surface area of the filter medium is second only to the OEM filter.
Unfortunately, we found corrosion aka rust! Flakes of rust flowing through the oil system aren't desirable - not one little bit. For these drivers, synthetic is better because it can withstand these unique environments better than regular motor oil. Cold Climates. If you live in an area where the low temperature can reach F or lower, synthetic is the way to go. These cold temperatures can cause regular oil to break down faster than synthetic. Non-normal driving: racing, towing, hauling, or off-road driving.
Pretty much, any time your vehicle is going to be used in a situation different than normal driving stop and go, highway , you should consider synthetic. These other driving situations can put a lot of strain on the engine. If though, you regularly tow a bobcat to the job site, this applies to you. Synthetic Blends, Buyer Beware There are a few different varieties of oil out there and one of them is a synthetic blend.
However, you should continue to check the oil level regularly and top off if needed. That will help your engine get the full benefit of synthetic oil. In the case of vehicles with 10,mile oil change intervals, the 5,mile service interval has not been eliminated. Replaces: SU Description: Fits 86, FR-S Fits: Toyota: GR Supra.
