nobody eh?

 

Correct, no one has tried it. Try it and runs some UOAs.

 

getting ready to take car out of storage and do an oil change. Does the rotella t syn 5w40 work pretty well on stock blocks? I have greddy tt but haven't built the engine yet.

 

/\ Check a few pages back for my latest analysis, Quadcam also had great result and both of us are on stock block.. Go for it. One thing I notice is that my oil still look very good/clean even after 2000+ miles of driving. When I used to use Mobile1 0W40, the oil is already dark when it reaches 2000miles.

 

that oil color change could also indicate the oil works because it changes color due to it getting out that sludge stuck inside your engine maybe?

 

Or the AOs are working effectively.

 

I thought I'd add some data into this thread.

I have an 07 stock block HR-TT with about 21K miles, roughly 4K boosted. Sorry, I don't have exact mileages. The shop that did the work switched the oil out from the dyno that the dealerships use to M1.

 

Did you have the M1 in for the "roughly" 4K?

 

Yes. I was told M1 0-40 was in the crankcase when I got my car back. But I don't know how many times the oil was drained(?) while the build was happening.

 

With that kind of mileage the M! did real well, too well. From what Ive seen it shears to about 12cst and iron is a bit higher. Resample it again in another 3-4K. M1 0w40 again?

 

I put M1 0-40 back in with an M1 filter. You better believe I am watching it.

 

OK, I read the whole 39 pages of this thread and the amount of info is amazing. Thanks to Resolute for doing all this, and thanks to everyone else for positng your UOAs.
Of course, as it happens, I do have a question :-P

I think I want to go with either GC 0w-30 (if I can find it), or Mobil1 0w-40.

I see that the Mobil1 0w-40 has great results but it seems that it's mostly guys running FI use it. Would it be suitable for my stock daily driver, driven fairly conservatively, in Florida, assuming a 5,000 mile OCI?

Also, would USA-made Castrol Syntec not be good for 5K-mile OCI?

 

Will and I have both run the M1 0w40 and we are stock. His are part of the tables at the front, I dont think mine for 5K are yet. I have it in now and will run for 7500. The Syntec hasnt done awful for 5K runs Ive seen, but there are much better oils for the money including regular old GTX.

 

Sending out my most recent M1 10W30 to BlackStone tomorrow. Added Rotella and gonna give it 5k till my next change.

 

you talkin bout syntec as in the 0w30 german? or just the regular 5w30/10w30?

 

Here's my oil analysis results. I think this is the first report for Torco oil. Here are the details:

Oil: Torco SR-1 10W30
Engine: VQ35DE, rebuilt
2600 miles on engine, 930 miles on this oil change (4th oil change)
Wiseco pistons, eagle rods, Cosworth bearings

Any info appreciated, especially comments from Resolute

 

gc excluded.

 

Do you know where do they get their universal avg from? Other VQ35 engines or passanger automobiles in general?

 

I dont know how many samples you've submitted but as you can see your molyb stands out. MolyB is a type of grease used in engine components and most likely just a little excess from the regreasing of engine components.

I saw this is your 4th oil change. Have you been submitting samples for the previous 3? As your engine breaks in a lot of metal particulate will show up at first. As long as the trend is decreasing I'd say your doing fine.

 

The M1 sample looks very good. Like Nederlander75 posted, most M1 0W-40 samples are shear stable as a heavy 30 weight oil, and therefore show up in a UOA as a high 12.xx cSt viscosity. My own sample with 3200 miles (albeit with 410 track miles) being a typical example. The P amount is low for M1 0W-40 as well. What is really weird, however; is how your M1 0W-40 has very little boron in it. While the other M1 0W-40 samples all show a healthy dose of borate esters, your sample is lacking. Same for Molybdenum, where your sample shows about a third of the average amount of moly used in the M1 0W-40 formula. The calcium level is also well outside of the standard deviation for the average amount contained in M1 0W-40. Either this is some new formula of M1 0W-40, or it is not M1 0W-40.

As far as wear is concerned, the values all look very good for a TT engine with 4k miles of use.

The high Si and Sodium are a concern. Neither are used as part of the additive package in M1 0W-40, so this is not normal levels for this oil. First, and most obvious, is double check the air filters and vacuum hoses for any leaks to allow these elements to be ingested into the crankcase. There are a number of other ways these elements could become elevated in an oil sample, but check the obvious solutions first and get another UOA during your next change to check trending.
