With all the posts regarding ignition misfires, coil pack failures and plug problems it seems the oil companies are trying to help with a new reformulation and classification (SN plus or SN +).Our small displacement GTDI engines seem most susceptible. Haven't seen any of the 5W-40 weights reformulated yet but many already add the classification to the 5W-30 oils. I will be changing to it on my new '20 N-line @ 1000 miles.

I use OEM filter just to prevent dealer from giving me any hassles.
You mean for warranty? They can't deny for doing your own maintenance and using the appropriate filters and fluids. Hyundai doesn't make their own filters it just has their logo stamped on it.
I prefer that my engine lasts outside of warranty so im using a filter that has a decent micron rating and an oil grade designed for protection not fuel economy. I can't find the rating for the oem part number 26300-35504 but im guessing its crap considering that's what hyundai says to use after people ran non oem filters with too high of a rating and it caused a "ticking". Likely from restricted oil flow to the VVT system.

Believe me I understand what you are saying. I have no plans on keeping this TGDI motor past my 3 year lease. When it gets turned in it will have a Hyundai filter on it. The OEM filter will be fine and is inexpensive.

Also why would Hyundai make a crap filter if they provide a 100K warranty. That sounds pretty ignorant on their part if they would do that.

I know people can have 20 page discussions about oil filters but when it comes down to what dealers can point a finger at..... the OEM filter is not one of them.

To me running the new SN + oil specification is more important in combating the issues TGDI motors have than filter selection. I usually change my oil more frequently due to alot of city driving too.

I wouldn't even care that much for a lease. 100,000km warranty isn't a whole lot, its only 1/3rd or less the expected lifespan of the engine. First change was around 3600km because the oil was almost a year old since the car was built plus it looked thin and smelled like gas. Done every 5-6000km since. Use 1/4 to 1/2 a can of crc gdi cleaner before I drop the oil and fuel cleaner in the tank after. 87 octane top tier. It was idling a bit rough somethimes before I installed a catch can on the pcv to the intake. I don't have any of these TGDI issues you speak of.

Yes I mean for warranty issues. No auto maker manufactures their own oil filter. This is not significant with respect to quality. The filter is made to Hyundai specs. You certainly have an interesting perspective on what makes a filter good. Other filters with better ratings resulted in ticking yet the OEM filter is crap. Does this higher filter rating actually result in great engine longevity or is it a feel good number?

Like I said im guessing because I can not find any info on it. It appears to be a good filter and its inexpensive, that is mainly why I don't trust it. I know im buying good filtration media not just a cool looking blue filter with a hyundai logo stamped inside it. Less containment in the oil absolutely means longer engine life. I have seen heavy truck engines with 2 million or more killometers and the crank/cam bearings look brand new because it got regular changes with synthetic and good filters.
