Castrol EDGE does it all...

Castrol EDGE or EDGE EP - which has better ingredients ?

EP, but your car won't know the difference until you hit 10,000 miles.

It stands to reason that their premium product would automatically have at least what their cheaper products have.

Even if it weren’t true they can’t very well write back and say; Actually, GTX is better. We can’t figure out why.”

Now THAT IS FUNNY!!! LOL!

Or the intelligent molecules try telling the sludge buster molecules how to behave and act... And the sludge buster molecules secede to just do their job without micro management from the intelligent molecules...

The first thing that came to mind when I read it was the drug tPA. Intelligent molecules breaking up sludge clots in your engine.

This thread has got way off topic, IMO. Getting back to Castrol, I read on Castrol website that GTX is a synthetic blend and Edge is a full synthetic. Is that relevant to the OP's question?

Only your hairdresser knows for sure.

I tend to walk right past the Castrol. Sometimes I glance and shake my head.

Please stay on topic.
Stop the bickering.
Let's not get this locked.

The GTX line does have a full synthetic product, it is what replaced the "Magnatec" product if I'm not mistaken.

So, with Castrol saying 25k miles guaranteed with an asterix at the end, on the back of the bottle it states:

“if your vehicle is under warranty or if driving in severe service applications, follow the oil change interval recommended by your manufacturer. Examples of severe service applications would be racing, frequent towing or hauling, excessive idling or commercial use.”

So with that being said, 99% of average drivers should not go 25k miles with this oil. According to Castrol, the only time you can actually go 25k miles is if you’re only doing very easy driving only, and I’m assuming they mean highway driving only. The asterisk basically admits that this oil should not go 25k miles for 99% of drivers.

One of the biggest and most fraudulent marketing strategies with vehicles nowadays are “long drain intervals” and “lifetime fluids”. They make these claims so buyers think they won’t have to spend much on maintenance. But 99% of the time, the people that follow these claims using average fluids and chemicals pay a big price right out of warranty, having to spend thousands, or even tens of thousands on replacing engines and transmissions.

Has anyone actually gone 25k on this oil? How did it actually do in the real world?

OK. Well then some (or most) of the GTX oils are blend. If some GTX oils are full syn, it wasn't mentioned on the Castrol webpage that I read. I think all the Edge oils are full syn. I'm not a Castrol user so I'm less familiar with Castrol products.
