Robert,

That doesn't look too good. Your Chromium is pretty high, which suggests piston ring wear. As a rule, I don't like to see anything over 1ppm for Chromium. Your Fe is higher than average, but Fe is always high with M1 oils, so it's hard to say if it's from lining wear. Bearings look o.k.; Copper is a hair higher than I'd like to see, but Pb is low. I imagine the fuel dilution might be increasing some of your bearing or valve guide wear, but it most certainly has lowered your flash point to an undesirable level and has contributed to your oil shearing down to a very thin 20 weight oil. This oil isn't anywhere near a 30 weight anymore. The sodium is way too high. Why is there a question mark on coolant? Did they detect some coolant or no? I would be curious if you noticed any coolant in the oil when you did the change. I think this UOA might save you some damage costs and alert you to some developing issues, such as severe blow-by and a coolant leak. If I were you, I would keep a close eye on the coolant level for any change over the next oil change interval, and use a good diesel engine lube like Rotella T-Syn 5W-40 for the next 3k miles. The Rotella T-Syn will manage your fuel dilution much better than the M1 you're using, and it costs less. Then get a UOA and see if the sodium and coolant traces are better.

Thanks for the info Will. This is the first oil change since March '07 when I had the TT kit installed. Make note the car sat from April till August. Also worked out a lot of problems that arrised from the elevation move. Had coolant issues and upgraded the injectors and fuel return system. I'll do another report at 3k miles with the M1 10W30 I'm currently running.

Question: Could these factors be abnormal due to all the new parts? EI: TT kit, Radiator, Oil Cooler, larger injectors/pump, etc.

I'll also try the Rotella T-Syn 5W-40. Do I need to order it?

THANKS!!!

 

Hi Robert,

I think this happens when a FI kit is put on a stock block, and become s just a fact of life when running boost. That being said, guys like QuadCam are boosting and their UOA's look awesome with no fuel dilution, coolant traces, or abnormal wear. Hence why I don't keep track of the FI UOA results, because the build, boost, tuning, kits, etc.. all introduce too many variables which have a dramatic affect on the UOA results.

Rotella T-Syn can be found at Wal-Mart in gallon jugs and one-quart bottles.

Will

 

Thanks! Figured so being boosted on stock block. Hopefully this time next year it will be built. Anyhow... I'll give this M1 till 50k (>2k more miles) and switch to the Rotella.

Thanks again and tell Becky Ada & I said "Hi!"

Will do, thanks! You and Ada enjoy that nice Texas weather and your 80mph speed limits!

Will (is sad that it's snowing outside and he got a ticket that wouldn't have happened should Colorado adopt 80mph interstate speed limits, instead of 55mph)

 

We do have 75 here in places.

 

Which just isn't as good as 80

It's still 65 on I-25 south of COS until you get past Fountain, CO. It's a stupid speed limit to have for such an open area, except that I'm sure it's a nice revenue generator.

After using Mobile 0W40 for about a year I finally switched to Rotella T 5W40. My Iron is much better and I think I'm going to stick with this one. I only have 2400miles on the oil because I was doing some work (tranny, Diff fluid change) on my car so I decided to change the oil as well. The 2400 miles was definitely wasnt babied, it has over 25 1/4 mile drag (14 at the track and over 10 with my Gtech). It also have countless of WOT pull all the way to redline when I was tuning and preparing my car for the Track.

 

Rotella Tsyn is looking more and more like a winner. Relatively inexpensive too.

 

Essentially identical wear results, but with less Fe wear and at a lower price. Gotta love The T-Syn, it's been a stellar performer in every VQ that's used it. Thanks for contributing, athenG!

Will

 

What mods do you have?

 

STS Single Turbo on stock block and some other bolt on...

 

im due for a second oil change now...need help what oil to use next..im using Royal Purple now 5w-30 thanks

 

Just thought I'd post up an analysis

06 revup, Castrol 0w30 German, Mobil1 filter ran for about 3100 miles. I only changed it because it was over a year...

 

No issues with the oil or your engine according to that UOA. The average copper wear result with GC is a little better than this for approx. 3k miles, but I imagine the car was sitting for some time in-between driving, or had a lot of really short trips, which doesn't make things easy on the oil. Moisture build-up and additive fall-out occurs with long periods of inactivity, and makes cold starts even harder in terms of wear.

Will

 

Thanks Will for looking at it! the car did sit mostly all winter, and your right i did take it out for a few short trips, but for the most part i try to keep those to a minimum.

 

I saw it very cheap at Walmart today.

 

15/gal today here.

 

^ That beats Nor Cal prices...wow.

 

that's insanely low!

autozone has it for $19.99. advance auto now carries it, but they are asking $23.99 for it.
