90% of the time this car gets started and stopped before it has been driven 5 miles at 35MPH by my wife. It's only when she goes shopping or visits her sister 140 miles away that the oil reaches operating temps for a reasonable amount of time.

Wear metals are trending down, but appearingly really good to begin with. Any insolubles, flashpoint, dilution data?

 

[ChiTDI]

My bad. Didn't scroll properly.
Stop and go explains the fuel.

 

[INDYMAC]

Thank you for editting for me Bill. I hope it didn't take up too much of your time.

Awesome UOA, INDYMAC.

About the only thing that raises any question at all is the TAN number, but TBN is even higher.

Looks like LE8130 every 5K miles + PureOne + LX2300 every ~1K miles + air filter changes every 10K miles = the secret recipe.

 

[INDYMAC]

Thanks CougarRed. I'm pretty pleased with the wear in with this engine. It's strong, but not well suited for a FWD car. It creates some interesting (scary) handling moments under WOT. I think Lotus might be onto something by inserting it into their new Evora 3,000lb RWD sports car.

This batch of 8130 seems to result in elevated TAN. I noticed it on a recent Tundra UOA too. It still had good residual alkalinity on both UOA's though. My earlier experiences with 8130 showed TBN depleting faster, but TAN was held in check better. Neither scenario appears dangerous in any way though.

The PureOne oil filter did not hold up well. It was imploding and the pleats were very distorted. I decided to go back to the Toyota filter. If you want to see pictures, PM me your email address.

Yes great results INDYMAC and thanks for the link!

I strongly recommend the Original Toyota Oil Filters,
specially the Factory ones, not the aftermarket ones.
The factory ones end in numericals only (1001, 2001, 2003, etc., while the aftermarket types end in alphabets luke YZZZ, etc.)

 

[INDYMAC]

I did switch back to the OEM Toyota filters (cartridge filter element). They are much sturdier and seem to filter just fine.

I'm also trying LE 8530 (5W-30) now. I'll post a UOA after a couple of fills.

Very strong oil - I'd go 7-8k with it, can easily do it.

But very nice results nonetheless - visc. stability is impressive, even with all the fuel!

By the way what in you opinion caused this "destruction" to the filter, if anything other than the quality of the filter itself?

 

[INDYMAC]

I wouldn't say that the filter was destroyed. It still filtered effectively. It was noticeably smaller than an OEM Toyota filter, and less stout/rigid. Maybe those are some reasons for the noticeable dis-figuration while in service. I sent Purolator an email with pictures, but never heard back from them.

Great showing here! LE lubes are working well in your engine.

Thanks Indymac

Thank you for continuing to post the rare LE samples here.
