Not fuel diluted. Never seen this shear down out of grade like this. Also what do you make of the TAN. Never had that tested before.
The 103 lead is false read from race gas used in my Primer/idle system.
I'm dam please with the metals and low silicon

My 1st test with Polaris Labs. Had to call them after they failed to follow my directing as to the testing. Should have a new test back soon as well as the VOA of the same

That is a serious engine.

I'm not sure how to interpret this UOA but thanks for posting it. I love reading UOAs and this one is probably the coolest one!

I meant to say Fuel NOT deluted

I'm not sure what the virgin viscosity is...but it is still a SAE 40. Regardless, the wear metals look excellent.

What more could you ask for?

 

[quick_16]

I just posted the VOA of the same in the VOA area, but here it is togeater with the used one.

 

[Colt45ws]

Actually, it didnt shear at all, it looks like. 13.7 to 13.5? Well within tolerance.

 

[quick_16]

Any idea why the Si is 16 in the VOA and UOA was 9?

agreed but on the low end of a SAE 40W
12.5 to 16.3

 

[quick_16]

Here's a revised test. I was not happy how they ran the 1st test so they redid it. I'll place the 1st test below as I can't edit the original post.

 

[Colt45ws]

Meh, yeah, but what matters is it held. If it was 15 and dropped to a 13.5 would that be any better? Mix some 50W in with it if you want thicker.

 

[quick_16]

That's odd the Schaeffers data sheets says TBN of 8.3 but the VOA has 5.53
Any ideas?

 

[Colt45ws]

Thats the UOA that has 5.53 TBN. The VOA just had TAN.

Yep brain out of gear. Polaris still owes me the TBN on that VOA.

TAN maybe a cool deal but I'm use to seeing TBN and I should see it close to the spec sheet that says 8.3
