BlackStone VOA sample.
Oil is Pennzoil Motorcycle/Out Door 20W50. Feb 9, 2011

SUS Viscosity @ 100 C = 18.42
Flashpoint= 450

Silicon= 10
Sodium= 6

All other elements are 0 because of the VOA.

Any input?

Hi.

Looks very similar to an HDEO.

But until a virgin oil is used and then analyzed, we would not know how it performs under operating conditions.

Use it; it's fine. And please post your results after the UOA. Then we can determine if it's a good oil.
 
It is an excellent mineral based motorcycle oil, if your motorcycle requires 20W-50.

It is made with a Group II base stock, has a strong TBN, excellent levels of boron, calcium, phos, zinc, and moly.

No doubt in my mind what it will look like after a suggested oil change in a Harley.
 
Yes, exactly what Blackstone commented (The TBN is strong at 8.0 showing lots of active additives, this oil will work well in a Harley.
 
Pennzoil stoppped manufacturing it because of weak sales, the good news is that you can still get it from www.oil-store.com
the cost is just over $3. a quart with shipping, current wait time is 1-2 weeks, I just bought a case this week from them, I would have bought more but I already have 2 cases on hand. Thanks
 
Hi,

Absolutely, I will do a UOA, as soon as this darn winter breaks here in Michigan. I also plan on providing a VOA on Pennzoil's GT Race 25W50 for a quick comparison, the more robust the better for me. Stay tuned! Thanks.
