millerl · Jan 9, 2003

Castrol GTX 5W30 VOA:

Aluminum 1
Molybdenum 53
Potassium 1
Boron 2
Silicon 5
Sodium 1
Calcium 1720
Magnesium 3
Phosphorus 716
Zinc 801
(All other numbers 0)

SUS @210 =61.2
Flashpoint =440
TBN =9.5

Oil analysis performed by Blackstone Labs on 6 Jan 03.

Patman · Jan 9, 2003

61.2=10.6cst at 100c by the way.

This is the oil going in my sister's car for the next two intervals. Each interval will be 6.2k (10,000km) since she racks up highway miles fast (about 500mi per week, sometimes more)

Nice TBN and flashpoint for a low cost oil, and a nice little dose of moly too. This oil sells for 95 cents US per L up here at Walmart right now! (a 4L jug is $5.98 CDN)

Patman,

Since millerl is from Belgium, I'm wondering if the GTX he's had tested is the same GTX sold in the North American market. If he got it in Europe, it isn't.

Patman · Jan 9, 2003

Good catch G-man, I didn't notice that! Hopefully it's the same stuff we get here.

Terry · Jan 9, 2003

The GTX is shipped to Belgium and is a AFEES (US product), millerl can confirm that for us.

This is more of a continuation from my post on the SuperTech oil, but other than moly, this virgin analysis looks almost exactly like the Valvoline that was claimed to be "not worth putting on the shelves of walmart".

I don't think the Valvoline had a TBN as high as this though did it? Or a flashpoint this high.

According to the VOA ( http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=11;t=000008 ), the TBN and Flash for the Valvoline was 10.5 and 425.

Yes indeed fellas, I bought it at the Base Exchange...it's the same old US-spec Castrol GTX you get at Walmart, etc. Uhm, except that I certainly don't get it at the Walmart prices! LOL. We have to pay closer to $1.69 for it...ouch!

hooah!

The PX/BX at Ft Bragg looked and smelled JUST LIKE Wal-Mart, except there are a bunch of NCOs and enlisted walking around w/ BDUs and caps instead of soccer moms and kiddies running around.

Here in Malaysia Castrol launched a new API SL Castrol GTX last year. I just got the data sheet today. These are the numbers:

SAE Rating: 15W-40
Density @ 15°C, g/cm3: 0.884
KV @ 100°C, cSt: 14.4
KV @ 40°C, cSt: 103
Viscosity Index: 138
Flash Point (PMCC)°C: 200
TBN, mg KOH/g: 8.8
CCS, @ -15°C, cP: 3200
Pour Point °C: -32

The oil does contain moly.

Terry, JB,

Was this the same oil Castrol that Ken used that turned in such great analysis numbers?

Nope. I think this is the oil your asking about,,and FWIW it really does not have enough miles on the interval to deem it a great oil IMO

Castrol RS 10/50

Ohy-ya-ve-te-ahe.

That's Cherokee for, "Boy did I misread that."

Thanks for the clarification.

Terry · Feb 26, 2003

Mola, hla.

Terry

thats no in Cherokee.

Western tribe.

MolaKule · Feb 26, 2003

Yes, but, you Western Cherokee types have a funny accent.

Terry · Feb 26, 2003

That comes from the long walk our ancestors took to get to the promised land of Eastern Oklahoma !

'Kule & Terry, you mean you guys can add the title of "Wind Talker" to your resume?

Terry · Feb 27, 2003

Bror, I have been called a " wind breaker"

but not the kind you would want to wear !!!!

Cherokee has a written form so it would not have been a good code language.

I don't speak it but I can read some from Sequoyah's syllabary and my Cherokee English Dictionary.

My Grandmother is Cherokee, from near Mena ,Arkansas.

Oh cr@p, was I thinking of Apache?
