ENEOS/ENEOS Sustina 0W-20 used oil analysis: was:ENEOS 0W-20 versus factory synthetic

Just got sample of ENEOS back. This one was 4401 miles (first change was at 1665, but factory fill was lost in shipping).

Two things: Sidenote: TBN was requested but somehow skipped. And a FilterMag was used for entire duration of oil use.

OE Subaru (black) filter was used.

Will stick to regular ENEOS for time being, as I don't see any justification for paying more for Sustina via UOA.

Next interval will be >6000 miles.

You're probably right, but it will cost you way more than one random $25 uoa on a car that is still breaking in to make that determination.

Although the regular Eneos is good stuff and has the new Molydenum trimer (although you are still seeing residual moly from the factory fill).

I suppose that BS is telling you to extend the interval based on the fact that fuel dilution doesn't look too bad (which is based on the flashpoint, not an actual fuel reading) and your oil shouldn't be too "spent". Blackstone should still have the sample, so you can email them if you really want to know the TBN.

I'm fully aware of the limitations of UOA, I ran ~100k worth of tests on my S13 240SX from 2002 to 2004 (upping interval from 3500 to almost 6000 miles) , and have a good gauge of what they tend to report.

I did ask them to rerun the test (as I had paid for TBN but it did not show up on my report).

Virgin sample was 6.2, used sample with 4400 miles was 2.8

Just got my latest sample back. This interval was 7300+ miles, with really low copper readings.

I also ran 1 track event during this particular oil change interval.

Next reading will be ENEOS Sustina 0W-20, as I got 2 cases for $100 (couldn't pass up that type of a deal!)

Looks good!

Got my UOA from ENEOS Sustina back:


A few notes:

• 8000+ miles, including a 2100 mile, 4-day road trip.
• 3 track events
• Approx. 1/2 quart of oil added
• Approx. 3000 miles on Cusco oil cooler (same as DIY Forester XT setup)
• Changed oil filter once (due to Cusco oil filter install)

The high TBN (compared against regular ENEOS previously) is pushing me towards running Sustina beyond this upcoming oil change... this sample was pushed relatively hard with all the driving and track events, and the oil still held up well.

Food for thought.

Note: I drove the car back from Colorado to Los Angeles, with a stint through Las Vegas > LA in 105+ this past week.

The virgin oil sample could not possibly be The Sustina. There are no visible gold flakes.

BTW I would like to personally thank all of you who have the courage to use The Sustina, and to also post your UOAs. You are changing the World.

The Sustina is selected by the Japanese engineers who designed this freakin' engine as the correct oil to use.

I now feel vindicated for conducting my groundbreaking consumer field study test, running The Sustina out to 20k miles and for 60k total miles. It's very emotional.

Haha thank you... The original picture was of virgin regular ENEOS, I recently started using Sustina as I had a killer deal on them (2 cases for $100).

Eneos Sustina 0W-20.
I'm on my 3rd Eneos!

Updated 6/7/2015.

The report dated 2/20/2015 and comment about high silicon was probably because I had my car serviced at Subaru dealership.
I had CEL and they had to change sprockets? and etc and took them about 2-3 weeks sometime in December.

Anyways, I have another oil sample that I still haven't sent to Blackstone Labs.
Will update with new readings soon.

Cheers!

fx35s - I would do 1 yr/7,500 mile intervals. Looks great!

Uh-huh. Tried to tellya a year ago at least. Actually 2012! This UOA shows the signature of The Sustina 0W20-significantly more phosphorus than zinc. And yet it is GF5/SN and easy on cats.
It is very interesting to me as far as the big picture on motor oil goes. All the different forces coming into play. Smaller GDI Turbo engines. GF6, which will require better and better emission system compatibilty. And the big one. Maintaining viscosity and shear stability while being efficient.

Where's regal? He'll probably pass out and hit his head on his keyboard when he sees the low ZDDP. He's an old school high ZDDP kinda guy.

The moly, boron, and calcium are all multi-functional additives so you're getting anti-wear protection from them as well.

Yes. Outstanding, professor. I saw an old paper from MoleKule talking about how tenacious boron is.
