VML vs PHM

[Ga129]

Which one would yield a longer OCI? And which would be better for the engine (seal conditioners/additives/etc.)? From what I understand the VML is synthetic blend/full synthetic and the PHM is Conventional, which would mean a longer OCI with the VML right? OR should I go with Full Synthetics like PU and VSP which I know yield long OCIs?
Thanks in advance.

Valvoline MaxLife is about one of the most popular HM oils around here...lol. dont think you'll get many suggestions for Pennzoil

I do like Pennzoil products, but yes, have had great luck with MaxLife....

I've used VML before in this car and it did fine I guess but just looking for different opinions and comparisons

While VML might be just fine for your application, it's better to match the oil to your driving style rather than fit your driving style into one of the four oil profiles listed above.

Does the info in your signature apply to your question?

I've been quite the fan of Maxlife and it has worked exceptionally well for several vehicles. The latest formulation of Maxlife leaves me pretty underwhelmed though. I've had really good experiences with regular PYB and at this point I'd lean towards giving it's HM cousin a shot.

 

[Ga129]

Yes, sorry didn't mean to leave that out, that is the vehicle in this application

 

[Voltmaster]

MAXLIFE line up are great stuff for older cars that need that extra seal swelling and doo dats.

PYB is about best oil out there if synthetic is not must , cant recommend or not recommend HM by Pennzoil over max life if you car actually NEEDS high mileage.

Pennzoil has become my all time favorite in past year , and I doubt they cut corners for their HM oil. Buy whatever is cheapest!

 

[Ga129]

Do y'all think my car needs HM oil? It only has 118,825 on the dash. And it's mainly hwy driving

 

[gregoron]

Is it leaking oil? If not just stick with synthetic if you want long OCI, or dino if you change more frequently. This also depends where the leak is. For valve cover leaks, just change the gasket.

 

[fdcg27]

If the engine is neither leaking nor consuming oil at any appreciable rate, it doesn't need an HM oil.
Stay with the Purp', or whatever, unless you experience a problem an HM oil might help with.
Between the two HM oils in your thread title, I'd recommend Nextgen Maxlife just based upon my experience with it in my old BMW.

What about M1 highmileage? It can do 10K easily.

My GS is at 184k miles......

I never used high mileage oils myself. At work we stock Valvoline so I have dumped lots of VML is various cars.

 

[Ga129]

No oil leaks to be seen or though of. Doesn't consume it either. Only reason I used royal purple this time was because they gave me 10 quarts for 20$. Trying to clear the shelves. I may just go with I'll synthetics then. Do y'all think I should go with 5w30 or 10w30? I want which ever is best for hwy fuel economy.

 

[Ga129]

Will also be using a good oil filter too

 

[Ga129]

Does anyone know why all the oil websites recommend 15w-50 and 20w-50 for this car?

 

[Voltmaster]

Only reason by high milage is if it leaks oil.

Im not putting high milage until its atlease 1qt / 2-2.5k.

 

[Cup of Joe]

Yes I do know why. Your Kia falls into a group of hyundai/kias that later changed the oil recommendations to 15w40 and up for certain engines. You must have the 2.4L engine if you are getting that recommendation. Living in MS and doing freeway etc I would go with a quality 10w30 myself or something heavier.

I ran 15w40 in a 2004 hyundai sonata with the 2.4L and no change in highway fuel economy FYI.

Please direct us to these oil websites.
A little humor is always welcome.
Your engine needs 15W-50 or 20W-50 like every other modern low specific output one does.
IOW, it doesn't and neither grade should be used in a country where quality oils of appropriate grades are readily available.
If you lived in a place where very thick grades were recommended merely because good quality oils are all but unobtainable, this might make sense.
You don't.

Choose a website yourself, mobil1 or amsoil or any other you like. Put in any kia/hyundai with a 2.4L or 3.5L you will get the same recommendation I have posted the tech info before.
