Hi guys, Looking for some advice on high iron numbers that I'm starting to see on my 2008 Chevy Trailblazer SS with just over 57k miles on the LS2. Engine is all stock other than an IEATSRT8 CAI (uses an S&B filter). This is my Fall/Winter daily driver and it sees mostly just highway miles - no...

This is an odd sample from my 2008 Trailblazer SS LS2 at 56k miles. Its the first sample that I've taken since 2011 since it was very consistent before. The high iron has me a little concerned. This may not be relevant, but the strange thing is that I sent in a sample for my 2009 Chevy Cobalt...

I have an odd question. I'm about to replace the high pressure fuel pump for my Cobalt LNF engine and the service manual indicates that "silicon-free engine oil", GM p/n 12345610, which I believe is just regular old GM Goodwrench 5W-30, must be used to lubricate a few of the fittings...

This is the third UOA that I've done on this 2008 Chevy Trailblazer SS since I purchased it used almost two years ago. The first UOA was using Mobil1 5W30 and the most recent two were using Pennzoil Ultra 5W30. For all of the samples I have been using K&N HP-1017 filter. Only modifications to...

Here are the last two UOAs for my 2008 Chevy TBSS. The previous sample (4923 miles) was M1 5W30 and it was the first oil run after I bought the vehicle. The current sample is using PU 5W30. For both samples the oil filter used was a K&N HP-1017 and the air filter an S&B (IEATSRT8 CAI). Mileage...

Only 4277 miles on this sample from my LMM, but it represents 1 year of use (I don't drive the truck that much). Oil was Mobil 1 5W40 TDT, oil filter was Napa 7202, air filter is Banks CAI. This is without DPF and EGR and mild (PPE +90) tune. Driving is about 50/50 city/highway on this sample...

This is the most recent UOA on my 09 Cobalt LNF. This car is my daily driver with mileage about 75/25 mix of highway/city driving. My average trip is ~ 20 miles. Car is completely stock except for GMPP Stage 1 tune and K&N drop-in filter. Oil filter is NAPA FIL-7082 (I did switch to the AC...

This oil report shows my last two UOA's. Both are ~ 4.5 months of 85% highway/15% city mileage (60 mile daily round trip for work) with Napa Gold FIL-7082 oil filter. First UOA was OEM air filter and most recent is with K&N drop-in. Oil is Mobil 1 5w30 that I buy in the 5gal jugs from Walmart.

Nearing completion of solid lifter 427" LS1 with dry sump and 7300rpm redline. This is a street engine that will not get the luxury of frequent rebuilds so oil filtration is very important to me. The dry sump system utilizes a remote Fram HP4-sized spin-on filter and I am looking for...

Following is my latest oil analysis from Blackstone Labs. I have posted my previous analyses with Redline and Mobil1 so a search should turn those up... Details for this sample: 2001 Chev S-10 4WD (ZR2) pickup, 4.3L V6, 58,500 overall miles, 5000 miles on German Castrol (gold flavor) 0W30...

I switched from Mobil 1 to Redline in my 2001 S10 ZR2 this last oil change. This is my latest analysis on the Redline. This truck is my daily driver and sees a good deal of stop-and-go driving, warmups, etc. Total miles on engine (4.3L V6) = 24,950 miles on oil = 4250 Aluminum 2 Chromium 1...

Here's my last analysis from Blackstone (will be using Terry from now on). This is with 2900 miles on my Mobil 1 Tri-Syn 10W-30. Sample is from my 2001 Chevy ZR2 pick'em up with 20,800 miles on it (yeah, its **** near my only source of daily transportation right now ). Anyway, the silcon was a...

This is the Blackstone Labs report for my 92 ZR1. It has ~38,000 miles on the LT5 and I've been running Redline 10W40. The car isn't driven very much and when it is its generally on short trips (most of which involve 7000rpms ). I've been changing the oil about once a year, but since it does...
