Okay sounds good.

Hi there dnewton3! Thanks for the insight on my report. I do remember you running the old triple protection formula for that run with your great results. I will run this out to around 12k perhaps with another sample pulled. I won’t bother this time with a filter change unless blackstone thinks I...

This rotella is CK/4 and I do not believe any rotella products carry the SN rating due to the zinc content. It had the newest labels on the jugs that read “reduced maintenance” I believe? The competitor labels of ck4 like delo and delvac I remember seeing the SN rating

2007 Duramax 8,092 miles on oil with no makeup fluid. AC Delco oil filter. 238,150 miles on motor. Nothing but a stellar report to share! Did not drain all of this batch, only used my fumoto valve for a sample. Blackstone recommended a sample at 12,000 mile mark. Happy reading all!

Thanks everybody

JavierH19 the 73k run was rotella T6 5w40 (cj4) The first one might have been Dino rotella?

Hello all! Just wanted to upload my recent UOA on my duramax truck with 8,000 miles on this sample with around 210,000 miles on the truck. As you can see from my previous reports this is the first report that showed some titanium. Blackstone never commented on this as its not alarming, but I...

I will get a receipt for sure of what was dumped in. The oil cap says 5w30 but I’m sure they could miss that as well.

Dealer said it looks like some of the factory assembly lube on the dipstick. Won’t change oil until 5000 miles. I will attach some pics some other time. Love this car by the way! Thanks all

What is FF? I can see dark metallic on my dipstick even before wiping it off. The entire dipstick. No pics yet, but will grab a pic real soon.

Hey everyone! I just acquired this vehicle in the description in post.. and this is the first time in my life I have ever pulled a oil dipstick on a vehicle and noticed what appears to be “clutch mud” on the dipstick. If you pull a dipstick to check automatic trans fluid you know what I am...

Looks good

Excellent

I greatly understand the higher particle count for wear metals was to be expected in a young engine.. but the viscosity loss was more of a concern. I have seen many times of Xw40 oils shearing to a 30 at range but not usually a Xw30 going backwards at all on these engines.

Do these year of duramax engines during regen have a tendency to dilute the oil with fuel like the older versions? Also with this motor still breaking in, I wonder if the fuel dilution is partly due to the rings not being sealed up completely? I hear different opinions from folks on how long it...
