Castrol Edge Extended Performance (Gold Bottle)

[CarbonSteel]

What are the thoughts on this oil for extended OCIs? I see that someone did a VOA of Castrol Edge Extended Performance (Gold Bottle) of it in 5W-30, but the TBN was only 7.7 (which does not seem conducive to extended OCIs), yet PQIA tested Castrol Edge (Black Bottle) and it had a TBN of 11.3.

Has anyone else seen a test showing a higher TBN for Gold Bottle or ran it for 15K or so and has a UOA to share?

I would think that BP would know which of their oils is best suited for longer OCI's.
Having said that, I would still use Mobil 1 EP for extended OCI's over this Castrol product...

Check the UOA section, although it starts with a lower TBN, it might have significantly better TBN retention than the Castrol black bottle.

That's surprising, since ACEA requires TBN of at least 8.0

PQIA ran a test of 0w20 and it had TBN of 11.63. I highly doubt the voa done on here by Blackstone was quite right. In fact others though the same thing because the Blackstone test didn't jive with the known PQIA test.
I bet the 5w30 is far more similar to the PQIA results like the 0w20.

Yeah, Bbhero some days I scratch my head reading some Blackstone UOA and VOA's

Castrol is so boring. How 'bout something more exotic and hard to get like Kendall full synthetic ?

 

[bbhero]

Good point Merkava

Yeah car51 I think every now and then Blackstone has a false result that is a head scratcher. This is one of those times.

Yep, must be testing error or a different methodology.

As I mentioned in timeau's voa, Blackstone is using ASTM 4739. PQIA and engine oil blenders use ASTM 2896. That makes a difference. If you send in a sample and ask them to use the same method as PQIA, the TBN will look much more impressive. Blackstone switched sometime last year as I recall.

My experience with Castrol's HDEO's showed super TBN retention, too.

There we go, thanks for the reminder, dustyroads.

 

[dustyroads]

You're welcome! However, it still isn't a great looking TBN (for extended oci's). I'm not going to say that it's on par with Mobil 1 EP or PUP.

I just know from experience that starting TBN can fool you.

 

[53' Stude]

Yeah, people here whine about MaxLife starting TBN and say how it holds on and it's not a "extended drain oil" which is B.S. If you ask me. It has NEVER let me down. Wonder what these same people think of MaxLife full syn?

 

[bbhero]

Well done dustyroads

Very good to learn new information. I wonder if or whenever the PQIA will test Mobil one EP??

I suspect it would fare well, but we all know how long extended drain experiments can take, particularly if one doesn't have a fleet, or no longer does.

Kendall is not a long drain oil and it was "fairly" boring in my Explorer and is too hard to get in my neck of the woods.

Maxlife has been ran for 15K+?

 

[53' Stude]

I don't know about that, but how many MaxLife Full Syn UOA's will we ever see.

Me too.
