Acronyms:

OCI = Oil Change Interval (mileage between changes)
OLM = Oil Life Monitor (in car oil change indicator)
UOA = Used Oil Analysis (analysis of used oil tested for oil performance, contaminants, wear particles etc.)
VOA = Virgin Oil Analysis (analysis of new un-used oil, gives a baseline for comparing to used samples)
BITOG = Bob Is The Oil Guy (forum for discussing lubricants of all types, lots of engine oil information there, lots of OPINIONS too, careful what you read... it's just another public forum)

Goal:

Since the Cruze 1.4T tends to be harder on oil than most, and with the confusion surrounding the OLM recalibration in '13 and newer Cruze 1.4s (reduced the OCI by ~30%) combined with the less than stellar performance of GM's Dexos1 Synthetic Blend dealership oil in the 1.4T (it's fine in the 1.8 and in most other non turbo cars), I thought it would be nice to have a thread dedicated to UOAs where Cruze 1.4 owners can see how different oils are performing.

Rules:

THIS THREAD WILL BE HEAVILY MODERATED. I do not want this to turn into a bunch of theoretical discussions about what your Pappy told you, what your neighbor does, why some oils/additives are supposed to be better than others, etc. I want this to stay focused on REAL DATA, which are the lab numbers returned for real UOAs on the 1.4T, and the 1.4T ONLY.

To make this perfectly clear, we're not going to talk about a product until there's a lab generated UOA to discuss. We're not here to discuss what people THINK, we're going to discuss what lab reports SHOW. If that leads to a boring thread, so be it. I'd rather a boring factual thread than a dynamic one full of BS and hearsay.

Method:

I will update post #2 with UOA links and information as they become available. PLEASE: If you have a link to a UOA that hasn't been posted yet, or you have your own UOA done, post a link to the information and I'll include it in the list. I will also update my Acronyms list above if there's something I've missed.

If we end up with enough consistent data I may be able to start charting performance. This is a "nice to have" for the future if we get there.

I will start by posting links to some UOAs I've found on BITOG. Let's go!

Testing note from XtremeRevolution:
If you want to get your oil analyzed in the USA, I recommend Oil Analyzers Inc (a private label for Polaris Labs), as they will accurately test fuel dilution, oxidation, and nitration, include TBN free of charge, and will also include a prepaid return shipping label with the price of the kit.

Pennzoil and Quaker State products produced prior to 2014 will be of limited relevance as they are no longer available. Just a heads up for anyone viewing those. There was a formulation change in Q1 of 2014.

AMSOIL Signature Series 0W-30. This is Terry's car.

13,000 miles on oil. 54,000 miles on car. 1.4L Turbo, Trifecta tuned. Based on this UOA, the oil could have gone the advertised and warrantied 15k miles. Boron (anti-wear/anti-friction additive) is a tad low, and Magnesium is a bit odd, but given that the Oxidation wasn't even flagged, the oil could take another 2k miles. Oil filter change at 7k. Note that the 0W-30 has a weaker additive package than the 5W-30 or 10W-30.

AMSOIL Signature Series 0W-30...

...Based on this UOA, the oil could have gone the advertised and warrantied 15k miles.
Added to the list.

Oil Analyzers seem concerned with the Base Number at 2.06 and rate the analysis a 3/4 on the severity scale.

KV100 = 11.9 cSt, up from their PDS 10.4 cSt, getting thicker. Stark contrast from the other SS 0W-30 sample which had high fuel content (reduced viscosity, 8.1 cSt), high BN (5.65), and only trace amounts of Iron (3 ppm vs. 68 ppm for this sample) at 11k miles.

Interesting.

The fuel dilution ruined the previous oil analysis. That was my biggest concern. However, it was determined that his excessive cold weather idling conditions were at fault. His conditions were 100% highway. I was very happy to see no consequential fuel dilution here. Iron is looking more normal, and all soft bearing metals are very low to nonexistent. This sample used the K&N intake filter for 3,000-4,000 miles, and the Injen EA filter for the remainder.

While Oil Analyzers notes it as significantly low, they do not note it as critical. While the acidity wasn't measured in this analysis, excessive acidity will manifest itself in elevated Lead levels. We find Lead at 0ppm. Driving was 70% city, 30% highway.

Here's a note I wrote up elsewhere, with PPM levels taken from an old BITOG white paper-looking publication:
Element accumulations are measured in PPM (parts per million)

Silicone: Dirt from intake. 10-30ppm is considered acceptable. We are at 16ppm.

Iron: Levels come from cylinder liner, valve, gear train, camshaft wear. 100-200ppm is considered acceptable. We are at 68ppm.

Copper: Bearings and bushings, oil cooler. Can include turbo bearings. 10-50ppm is considered acceptable. We are at 2ppm)

Lead: Bearing corrosion (excessive acidity from TBN depletion). 40-100ppm is considered acceptable. We are at 0ppm.

Silver: Wear in bearings. Can include turbo bearings. 2-5ppm considered acceptable. We are at 0ppm.

Tin: Wear in bearings. Can include turbo bearings. 10-30ppm is considered acceptable. We are at 0ppm.

Aluminum: Piston and piston thrush bearing wear. 10-30ppm is considered acceptable. We are at 10ppm.

Chromium: Piston ring wear. 10-30ppm is considered acceptable. We are at 1ppm. Elevated levels will be found with excessive silicone levels. This is why I make such a big deal about K&N filters passing too much dirt. Long-term piston ring wear WILL occur.

In the above analysis, we find fuel dilution at below 1%, which is exactly what I wanted to see. 100C Viscosity went up from 10.4 to 11.9. This is characteristic of AMSOIL lubricants. 30-weight viscosity range goes from 9.3 to 12.5. Below 9.3 is a 20-weight lubricant, and above 12.5 is a 40-weight lubricant.

Thanks Andrei, some great info for the thread.

I wasn't commenting so much as to suggest the levels were high, they are definitely not, just noting the drastic differences between the two samples for the same oil in the same engine used under different conditions by two different people. I also found it very interesting that the sample with so much fuel in it had such a high retained BN.

I'll edit my post to separate the first scentence WRT BN so it doesn't sound like I'm condemning the report. :)

FEEL FREE TO DELETE THIS BUT... Is there a preferred list of analysis labs to help control variables or list results?
Most labs run routine VOA/UOA in a fairly similar fashion. There's lots of talk about which labs are better than others with, as far as I know, little proof to support the "theories".

Blackstone, Oil Analyzers and Wear Check all come to mind as popular choices. I've got an oil sample kit from my local Toromont CAT heavy equipment dealer also, but I haven't used it yet. In Canada they're an affordable option compared to other labs, not sure how they come out value-wise with labs in the US.

I was helping a guy out with his WRX oil analysis. He posted his analysis for discussion on a subaru forum since it came back with high fuel dilution, and a member replied with the following:

Blackstone estimates the fuel reading by looking at your flashpoint result. In all likelihood the fuel dilution result in a BS uoa is actually higher than estimated. OAI uses a more accurate Gas Chromatography and actually tests for fuel.
Not only do they not properly test for fuel dilution, they don't test for fuel dilution AT ALL. They only estimate it, although his thought that Blackstone will estimate higher than what is present is false. Fuel dilution would have to be severe in order for Blackstone to flag it.

Yet another mark against Blackstone for oil analysis purposes.

Use Oil Analyzers Inc or find another company that actually tests your oil, not estimates it to save costs.

Here's a somewhat interesting one for you.

Mobil 1 EP 5W-20. Owner used this not paying attention the viscosity since it said "dexos1" on the label.

Boron depleted as would be expected. Everything else looked fine. Granted, only 5042 miles on the sample and the engine was well broken in by this point. Viscosity cSt at 100C started at 8.9 according to M1's data sheet, so a notable amount of shearing did occur given the mileage, and it wasn't caused by fuel dilution. No modifications on this engine. ZDDP levels were a tad higher than expected.

Side note: I will start uploading these as attachments moving forward in case any links turn up dead in the future.

Good to see wear metals low despite the lower than optimal viscosity. 30 wt oils range from 9.3-12.5, so his sample pulled at 8.2 cSt was a good chunk lower than the bottom of the range.

Here's the second UOA on my Cruze. 7050 miles on this one using Pennzoil Ultra Platinum. (the report has it wrong as PP) Not bad at all!

Sorry for the low quality image!I couldn't figure out how to convert the pdf to a jpg.

ZDDP numbers are off by a whole 10%, but that's to be expected. I've seen the same with Blacksone before as well. So far so good.

Excuse my ignorance. Whats is the ZDDP #'s and why are they off?
Zinc and Phosphorous. The two are mandated to a maximum of 800ppm and 700ppm respectively for API certified oils.
