You don't need expensive engine oil

[MerlintheMad]

5W-30, or SW-30, what if anything is the difference? The MY18 manual says "SW-30", see @Ohiocruiser 's pic You don't need expensive engine oil . But a search turns up nothing to do with "SW", only 5W.

Gotta be a typo

Figures. We drive a "typo".

2.5 is still new. Post a picture from your manual

It's interesting , rwd and awd have different capacities.

You must be new to the automotive enthusiasts world. AMSOIL is not boutique. They were the first to develop a synthetic oil that met the API requirement. Mobil1 or Castrol can't produce propaganda?? You know what happens when you assume...

Being first to market with X has nothing to do with being a boutique. Both can be simultaneously true and are merely coincidental.



In fact, being first to market with X yet failing to be the market leader for X suggests some bad luck or poor corporate leadership.

You improperly attributed a fallacy to my statement because you didn't understand it. Your original statement: "I think what you mean to say is there may be something better than ILSAC GF-6A. OK, let's start at first base: you first need to substantiate the problem with ILSAC GF-6A that needs fixing." My response: "Lastly, you presume a label which denotes specified requirements [ILSAC] is superior to the standard [ASTM/SAE/API] used to attain the particular levels." With the bracketed details, you can now see there is no straw man.

In my statement, I asked about what is the problem with ILSAC GF-6A. I am only getting crickets. Until we can clearly substantiate how ILSAC GF-6A is inadequate, we have no problem that is solvable by some other oil.

Your statement starting with "you presume" is the strawman. You are putting words in my mouth that I did not say, then attacking that false allegation about me.



Repeating a key point: if some other oil is better, then it has to be because ILSAC GF-6A is inadequate. Without evidence to substantiate ILSAC GF-6A inadequacy, there is no problem that a different oil would solve.

The transfer case is in the way I think. I'd say the #'s are pretty close. Eye balling the 5 qt jugs, I have ~ 3 2/3's qts left from the 2nd container. What I'm confused about is why isn't 5w-30 an option for the 2.5, aside from mpg.

I'm a big fan of pennzoil ultra platinum, which is api SP ilsac gf-6a compliant.

As times getting harder we all are looking for excuse to use cheap shit

Inexpensive oil doesn't automatically mean inferior.

This is Walmart house-brand oil. It's going in my Stinger GT2 (3.3L) tomorrow (yes, I have more than 5 quarts; this is one of two bottles):


It meets the required spec. It's perfectly fine for this application:

i like how it says "for better fuel economy " how about for better engine life ...

The two goals aren't exclusive. Conceivably, an oil that flows more easily might lubricate the engine better while causing less parasitic power loss.

Now i am wondering, will it be better to use 15w40 or even 20w50 for summer time only?

It is my understanding that lighter oils are necessary due to tighter clearances in today's engines. Years ago, I ran 20W50 in my Chevrolet 350 to build hot-weather oil pressure. It helped a little per the oil-pressure gauge. I cannot fathom why you'd want to put heavy-weight oils in modern vehicles with so much more precision in them.

The manual is showing both of them as acceptable weights. So maybe they provide better protection for the price of lower mpg. Not an expert here.

Apologies, I see that photo now.

Well, that yet another good case for why "conventional wisdom" can be bogus. Like those justifying use of expensive, boutique oils, I was basing my view of heavier-weight oils on a folklore-reinforced amateur theory.

I trust Kia's engineers far more than folklore-reinforced amateur theory.

Counterpoint (?): all oil types show as being appropriate through quite high ambient temps. If true, why use a heavier-weight oil? It will just cause more parasitic power loss. (But possible counterpoint to my counterpoint: parasitic loss could be so trivial that it only makes a difference in fleet-wide calculations needed for US CAFE standards.)

I'm still trying to understand why yet ANOTHER oil argument was started. If you want to use oil from Walmart that meets recommendations based on the manual....so be it. If others want to use more expensive oil that possibly exceeds recommendations that are in the manual.....so be it. Can we move along now?

Regardless of whether or not you want to believe the "propaganda" is up to you.

Years ago we had similar discussions on the motorcycle boards too. Many of us (self included) were running shell t6 15w40 in our bikes. It's a diesel oil (not energy conserving) which met many of the requirements for the bike. No issues here with engine or clutch across multiple bikes, each in excess of 40K miles (one had 85K).

Imagine minds getting blown when using diesel oils for bikes!.

Like i sad, i am just guessing here. With heavier oil you get thicker oil film between metal parts, wich results in less wear on those parts and less chance of metal on metal contact. I doubt our engines were built to F1 standarts.But since it increases parasitic loss in engine, you get lower mpg. Probably i am totally wrong through.

I started this because I was trying to assure I was purchasing the right oil for my car. I came across a disturbing amount of propaganda and folklore.

I don't think it's OK when people are induced to waste money because they run into so much misinformation.

We're both in armchair quarterback territory on this detail.

Changing anyone's mind on engine oil is harder than changing anyone's religion. You are aiming high here, very high

 

[JSolo]

Compared to some sites (censored, censored, censored, censored, and censored), the level of propaganda and folklore here is minimal.

I applaud your choice to save money, but just because you want to do it, doesn't mean others are wrong to spend more on other oils that claim to be better. I'm not saying you're wrong to choose Walmart oil, I'm just saying that while you have the right to do that...others also have the right to choose more expensive oils.
