Castrol vs Valvoline High Mileage Motor Oil - Which One is Better?

[Supermanclark]

Has anyone used either one of these and, if so, what was your experience?

 

[MalibuRam65]

Castrol had been great there high mileage is good . With that being said cant go wrong with neither

 

[PimTac]

How would anyone determine which is the better oil?

 

[WobblyElvis]

The cheapest one.

I think a question like this goes back to when we all started driving and started to address engine maintenance.
In my case (I'm over 50), Quaker State and Valvoline were considered cheapy oils compared to Castrol and Mobil 1.

I've used Mobil 1 my entire tenure behind the wheels of whatever I was driving over the years, Castrol was my second choice if the M1 I needed wasn't available at the time. So, that being said I'm going with Castrol.

Between those two, yes. Otherwise this question and poll is about as irrelevant a determination as there could possibly be.

 

[Corollaman]

I've actually had maxlife stop an oil leak so it gets my vote.

So irrelevant you have to give your worthless two cents. He asked a legitimate question.

If you can give a cogent and technical response with a substantive determination of which is better then I’m interested. I gave more actual information in my response than you did.

It wasn’t my worthless two cents. I stated the differences are irrelevant, and it’s my opinion that they are.

No you didn’t. You’re just a cranky old man that’s always rude to new members questions

Well, if you don’t think that the two oils have irrelevant differences then what would you say?

 

[AutoMechanic]

I’ve used both. Currently have the Valvoline in my Escape. Normally it’s the one I put in here. Castrol has never failed me either it cleaned up my truck engine pretty good so I’d be happy with either one. I think both are good oils. By far my favorite two brands.

I don’t care. I don’t take things as seriously as you do. That’s why I don’t have a stroke every time a PF video is posted here and why I’m not a jerk to every new member that asks the same questions. If I had to choose between the two, I’d take the cheapest one. And at Walmart, that’s usually Valvoline.

Used the Maxlife syn-blend (red bottle 5W-30) in my 2004 Hyundai Elantra that was consuming a bit of oil and slowed the consumption. Did nothing for the valve cover gasket leak since that was so old and brittle. But no matter, replaced it and that stopped the leak. Hard to quantify any real performance differences between the 2 other than people's experiences with both. That said, it would come down to price/availability like mentioned.

 

[OVERKILL]

The cheapest one.

This. Nobody here has test data that would allow one to determine which oil is better. What you'll get is simply personal preference so the question really shouldn't be which is better but rather which you prefer. @kschachn seems to be getting flamed for basically saying the same thing a bit more bluntly, but it's accurate.
