Blackstone Oil Report

[shanneba]

Anyone ever send a diff fluid sample to Blackstone?

I've sent in three samples, the results are all posted at BobIsTheOilGuy -
The first sample is the factory fill with 38,000 miles, the second was taken at the time I had the Quaife diff installed, the third is after 27,000 miles with the Quaife unit. I'll probably do another one when I reach about 110,000 miles.

Appreciate the info. Thanks.

I emailed Blackstone. They said my aluminum and lead levels, while higher than normal, were not super high, and could be a result of tracking the car and the longer oil change interval. Because higher RPMs would mean more wear per mile than low RPM driving. They were not familiar with the Total INEO Quartz MC3 oil so could not say if it has sodium additives, but said most Valvoline synthetic oils do use sodium additives (most Penzoil synthetics do not). The oil I used 2 changes ago was Valvoline SYNpower 5w-30, then Penzoil Platinum, then the Total Quartz (which got sent to Blackstone). Apparently enough sodium could have been leftover from the Valvoline to elevate the sodium level in the Total Quartz.

I'm sending them a virgin sample of the Total Quartz MC3 to see if it contains sodium, and what kinds of TBNs it has when fresh. Then change my oil at 5,000 or 6,000 miles as you suggested. If the sodium isn't coming from the Total oil or leftover from the SYNpower, that could only mean head gasket issues!

So....the miles on the oil sample was 8,473....they say that the Al and Pb (Piston and bearing wear), could be caused by extended use of oil from beyond 6k miles....yet he recommends running this sample for 9k miles?

Does.not.compute.

Bumpin the Blackstone thread. I got excellent news today.

Now that's what I'm talkin about! Nice findings there DW. Can't wait to get my kits and do see what comes back..It's like your car's report card!!

Edit: oops my bad this report is a tad bit old..but still good.

Kinda pissed it doesn't have mileage. This was done about 30k ago?

The report notes 127,000 miles...Isn't that the mileage on the car at the time of sample??

Got it. Missed it on phone. 23k miles old.

Got it. Dane, since your report yields positive results, when do you do a follow up test? Or do you?

Whenever... Really. Maybe I will do a 50K test.... At around 173k miles.

I'm still doing 7500 miles changes, so I think I'm good, and will check then.
