GC is a "green oil "pretender.

[G-MAN]

This is the true "Green Oil," the original Kendall GT-1, now marketed as Penn-Grade 1. GC is just a pretender.

Blasphemer, infidel

It isn't an Elf oil either. I believe the multi year charade is over.....

Please pour some in a glass and take a picture for us!

Funny how a little green dye can create so much excitement?

Yeah, but the fun part is in WHY Kendall (and now Brad Penn) chose GREEN for the color of their premiere oils. Do you know why?

because it is the color of mold on a month old orange?

Good guess...not.

The reason is because Pennsylvania Grade Crude is dark green when it comes out of the ground. In the early days of refining, the dark green color remained and carried over into the finished motor oil. As the refining processes became more and more severe, and more additives started being used, less and less of the green color remained in the finished motor oil. The green color was always the sine qua non of "Pennsylvania Crude quality" motor oil so Kendall started using green dye in their best blends to accentuate what little bit of the natural green remained. Brad Penn has continued this practice with their Penn-Grade 1 racing oils.

I rememeber being told by an engine builder back in the early 80's to use GT-1. They told us the engines they built wouldn't break in using the Castrol GTX we had been using. They said it was "too slick."

Schaeffers 7000 is also green. Maybe that's their secret...

Let's see schaeffers,castrol,penn
Schaeffers and castrol are of German heritage.
Penn.... , quakers?

Huh? Schaeffers is only "German" in the since that its founder was an immigrant from Germany back in the 19th century. Castrol was founded in the UK, I believe.

can we buy this green dye

Aren't Kendall SAE 50, SAE 60, and Nitro 70 still green?
Does that mean they're still made with Pennsylvania Grade Crude?
And what's the relation between Penn crude and paraffin wax?

 

[beanoil]

You want green? Get some Schaeffer's 7000. Prettiest lime green color ever. Doesn't have that gummy bear smell though. Still have GC listed in the FS section if anyone is interested.

No and no.

Because of its high natural paraffin content Penn Grade crude is a good feedstock for producing paraffin wax for food and cosmetic use.

And please don't ask if paraffin causes sludge.

I hope Brad Penn uses the same color green that was used in the old Kendall GT-1, a very deep emerald. I'll post pics when the case I ordered gets here.

 

[G-MAN]

My case of 20w50 arrived today. Looks like they are using the same emerald green color, but they have chosen to make it a lot darker than I remember the old GT-1 being. I think Brad Penn is really trying to mimic the green color of Penn Grade crude, it's that dark--almost opaque.

I'll post some pics later.

 

[G-MAN]

Hmmm...I'm beginning to wonder now if the green color is coming totally from dye after all. In the geological papers on Pennsylvania Grade Crude the most common description is "green in reflected light; red-to-amber in transmitted light." If you pour some of this 20w50 in a clear glass it looks dark green. Shine a flashlight through it and it's dark red.

But does it smell like gummibears??

No, but it does have a peculiar smell. I honestly can't say if it smells like the Kendall GT-1 I used 30 years ago because I can't remember what that smelled like.

This Penn Grade 1 has an almost "fuel oil" smell to it. Very distinctive.
