2005 Elantra OEM oil filter

[flinter]

Today, after 39300 miles, just for the fun of it, I decided to change my oil to synthetic for the first time and I used Pennzoil
Platinum 5w30, with the blue OEM Hyundai oil filter.

My Elantra is the GLS, garage kept, and MINT condition. It may be very well the nicest 2005 Elantra on the road. I have always
be doing 5000 OCI, with Motorcraft Syn Blend 5W-20 and OEM filter. The car runs beautifully and I have been getting fine
gas mileage.
So, I thought let me see if a full synthetic will really provide any real increase in gas mileage.

I have two questions......

1. I plan to run this oil for 7000 miles, will the OEM filter
be good to 7000 miles, or will have have to do a filter
ONLY change half way??

2. Did I waste my money using the Pennzoil Platinum and see
NO difference at all in mileage and protection??


I do a lot of short trip driving and have a 9 mile commute to
work in the suburbs with a fair amount of stop and go traffic.

Thank you!

I have a 2010 Elantra and love it ! Here are my thoughts :
I too use the OEM Hyundai filter , it's built like a tank and receives high marks . The filter should do fine for a 7000 mile OCI but due to your many short trips you should establish a time limit on the OCI of 6 months OR 7000 miles - which ever comes first . I would also add that staying with the MC Syn Blend for 5000 mile OCI's would be hard to beat - the new SN rated MC Syn Blend may prove to be even better ! You can't go wrong either way ...

I dont think you can beat what your doing with the MC_SS. Plus the new SN/GF-5 should do even better as far as long drain goes. Dont be fooled by the 'full synthetic" marketing label. And I wouldnt use anything other than that hyundai filter. Most aftermarket units are a step DOWN unless you drive a toyota or honda or subaru

Here I am going to play "devils advocate". My wife has an 07 Hyundai Sonata GLS that is a nice car. If you want to take advantage of one main reason why "most" not "all" people buy a Hyundai THE WARRANTY. If you do 5000-7000 mile OCI's that goes against Hyundais recommendations. Therefore, if you were to blow a moter, (unlikely but for fun sake) and you tell Hyundai you went 7000 miles on an OCI??

Yeah, Hyundai would have to prove that the oil was the cause, but in the mean time your held up with no car.

Do yourself a favor. Change the oil every 3K miles as stated in the warranty booklet, keep your receipts off all oil and filter purchases (if you do the oil yourself).

As for Better MPG's with Synthetics will cause an arguement on this board. Since I am not sure its actually proven that synthetics actually lubricate any better than a conventional oil. The additives that are in the oil is what may contribute to better MPG's not just the fact that its synthetic.

Now I am no Guru, just your average joe car enthusiast.

But thats my 10 cents.

Toyotas use Denso Filters, as does my Mitsubishi Evo, I use the OEM Denso Filters, how are these a step down? Im curious on that.

Jeff,

With all due respect, you couldnt be MORE wrong! Hyundai clearly
states you can go as far out as 7500 miles between oil changes!

And come on, what are the changes of me "blowing an engine" with
my strict maintenance?.....less than 1%!

 

[jim302]

I would suggest a good 20 mile or more drive at highway speeds at least once a month, hopefully a little more often to get rid of any moisture buildup.

Aside from that, the OEM filter will have no problems with a 7,500 mile OCI. It is one of the best oil filters you can buy for a car for under $10. The Normal maintenance schedule for your car calls for a 7,500 mile OCI with conventional.

In fact, the only filter that might last longer would be one of the synthetic media filters such as Amsoil EaO, Royal Purple, or FRAM Extra Guard. Keep in mind that there is a TSB regarding noise on some aftermarket filters, but the higher quality ones are probably OK.

You probably won't get any meaningful better protection with synthetic and a longer OCI than you would have by sticking with Motorcraft Synthetic Blend at 5,000 miles.

1. It should be fine.

2. On that engine, you might see a slight improvement in MPGs, but the PP will offer more short trip protection.

Hyundai specifies 3750 miles/3 months OCI for severe service in the manual. You have described severe service driving. They specify 7500 miles/ 6 months for "normal" service. There is nothing in the manual about extending the OCI with synthetic oil.

Joe states 3000 mile/ 3 month OCI. Oddly, my big manual says what I stated, but a smaller leaflet included in the factory paperwork says what Joe says.

The filter that came on my toyota was a Japan made denso. The one the dealer sells is a Thailand made denso; They have completely different media. I have had continuous issues across 2 toyota cars with these thailand denso filters. These "issues" all went away with the wix # 51396. The OEM P/Ns from factory: toyota # 90915-10002; Dealer part # 90915-yzzf2. I dont know why the thai filter didnt work for me, I dont have an apparatus to test them. But they didnt - multiple times. This was noted as a very noisy engine, low power and suspect vvti not working in range. YMMV.

 

[flinter]

Again....incorrect.

Late yesterday, I spoke to the service manager at my Hyundai dealer
and he tells me I can "absolutely" extend oil changes to 7000/six month with a full synthetic without ANY risk of voiding the warranty! As long as I dont extend pass 7500 miles, I am perfectly
fine.

As he stated, most of these internet forums are doomers and gloomers and always state the worst case possible.

OK two things come to mind here:

1. The factory backs the warranty, not the dealer. We are telling you the requirements required by the factory. This is information what we have in writing, not a phone call to a service guy at a random dealership. The factory can also choose to deny a warranty claim based upon the service records. I am not saying they will. but that they can. If the service records aren't complete, they have every right to do so.

2. Since you seem to know all the "answers" anyway, why are you asking the question?

The funny thing here is the is a good board filled with lots of good people who give good information and advice. I guess that is only for those smart enough to understand that. Hint- I don't believe this applies to you.

 

[flinter]

What I do know is many folks on these forms are doom and gloom.

Not sure what to tell you. Its your car do as you wish. To me to blow a 100,000 mile warranty over going a couple thousand miles more on oil? I side on the side of caution. My wifes warranty book says 3000 miles or 3 months. When we take it to Hyundai, the sticker on the windshield says 3000 or 3 months to return.

It may be a dealer thing, or not. BUT WHILE THE CAR IS UNDER WARRANTY I do what they say. After the warranty is up, I do what I want. But thats just me.

Your right, the odds of your engine having problems is nill, I totally agree. I just do what the dealer says till the warranty is up. Thats all. I think 3000 miles on Conventional oil is all I would want to do anyway which is in my wifes car. The use of synthetics is irrelevent to Hyundai since they are not required. They still expect you to change it per their intervals to maintain your warranty.


It is what it is. Do as you wish, If I get a chance I will scan in the booklet from my wifes car, but ultimately it doesn't matter what my wifes car says if your manual says something different.

Are you using the "Denso" brand filters made in Thailand? Or the Dealer Filters that are made in Thailand that say Toyota on them?

I know the media may be different, but they are still built to the manufacter specs, so Im puzzled on this. I did see the Toyota Truck thread about that Denso filter, not sure if that was you or not, but My Mitsubishi Filter that is made by Denso is made in Thailand. That is the filter my Tuner recommends for my Evo. Odd. Not sure what to think of this. I guess I can cut one of mine open and take a look. Where can you buy a tool to cut open an oil filter anyway?

Jeff

 

[ARCOgraphite]

Cut it open and look at what? They are built well, but without a test setup You have no way of telling if the media has flow issues (or if the dealer is selling chinese knockoffs) All of the filters purchased at the dealer have the toyota HOLOGRAM anti-tamper label. I had problems on a 05 rav4 and the current car and a previous suzuki 2.3L - all with the same filter, and it was the last thing I suspected. I would get a compatible Lexus p/n of a "made in japan" Denso with the foamed core density media - not the paper media. My filters were toyota marked denso made ... and tiny little buggers at that.

 

[Jeffs2006EvoIX]

I would want to believe anyway that either Denso filter (Japan or Thailand) would still be made to the manufacturers specs? I may have to call Mitsubishi Customer Service and ask about this. I know my tuner recommends using the OEM filter, I have tried K&N (the 1004 not the 1010 that is recommended for my car) and my used oil analysis came out very good with the K&N.

When I look at the K&N vs OEM Denso (thailand) the oil holes are much larger on the OEM than the K&N and the metal perforated core on the Denso had more holes in it than the K&N.

So who knows. I have read so many articles on different oil filters, higher flow may mean dirtier oil, or who knows. I figure since I change the oil every 3K miles, even the OEM Thailand made Denso seems to be doing well. We will see when I do my next UOA to compare it to the K&N. Only problem is, I am now using Redline 5w30 not M1 anylonger, so not sure how this will affect my comparo since Redline has more "metals" so to speak in the VOA compared to the M1 VOA.

Aren't Oil Filters also rated for how much Oil Pressure they create? Maybe going with one that is "High Flow" or using one that has "less flow" than OEM may cause some issues on a cold start up? High Speed Driving? Redline shifts? Food for thought.
