Oil Analysis 3 and Lead is way down

[jdmboy]

A couple things changed.

1. I ran no unleaded Torco
2. I never went past 7000 rpm
3. I switched to 40W A3/B4 oil from M1 30W
4. I basicly drove on waste gate boost
5. I added a huge oil cooler and dropped oil
temps 20C. Thet were 115-120 in the summer prior to oil cooler. With cheap M1 30W that can't be good.
6. I ran Valvoilne Syn Power oil treatment as well.

So was it the oil viscosity that caused the high lead previously or was it other things.

The car is running rich and is getting tuned again this weekend so I expect the fuel in the oil to disapear next round.

It is a JDM spec 2.0L turbo motor pushing about 420HP on 91 Octane pump fuel and closer to 500hp if I run race fuel and turn the boost up.

Any thoughts about the change/drop in lead? I am running M1 T&SUV this next round. The motor like it, I'll say that.

What is up with the huge magnesium value? Is that the SynPower?

I'm confused...You say you used 40W and 30W, do you mean single vis sae 30 and 40? I wasn't aware that there was such a thing as a 30W or 40W oil. I thought 20W was the thickest winterized engine oil available.

Considering you used VSOT, I don't understand the low moly.

I said "I switched to 40W A3/B4 oil from M1 30W".

I meant I switched from a 30 weight to a 30 weight. As in from 10w30 to 10W-40. Sorry fo rhte confusion.

I don't get the low Moly and the high Magnesium. I won't use the Syn Power this round either.

Ahh dang,sorry, Subaru 2.0L turbo motor, 2003 model with an imported 05 JDM engine. Oil was Penz 10W-40 Euro Sunthetic blend. Mileage was 3K on oil.

I said "I switched to 40W A3/B4 oil from M1 30W". I meant weight but got lazy typing. Sorry for the confusion.

I think you improved things three ways. Increase in viscosity, cooler oil temp and addition of syn power. Great improvement!
You need to get the fuel problem solved and it will drop even more. No sure about the Mananeese. Need an expert like Terry Dyson for figuring that one out. I would guess like Blackstone says left over from the addative. I used an oil with loads of sodium and it took four 6000 mile changes before it droped to a normal level again.

If your gonna spend the money on mobil1, i would not compromise its capabilities by using the additive. I was under the impression the synpower additive had a lot of moly, so i agree the moly numbers seem lower than i would expect.

I wondering if the Torco additive was throwing the lead reading waay off. I'm betting your lead reading will continue to go down if you stay clear of the Torco additive. Adding an oil cooler and stepping up to a 5w-40 is probably helping as well.

You changed so much that it's hard to say which or how many caused the improvement. I'd keep the vsot and start gassing it again so that there's only one new variable. It's gotta be hard to pamper that motor for very long.

Yes it is. One thing is clear, I do not have a bad bearing so I am retunung for power this weekend. I have let WAY too many G35 Yuppies of the hook. You know, with the "race" bred cars, reving motors past me tauning me.

Link to funny story that happend to me a while back.

Also I am not running SynPower in the T&SUV. I have to say, the car really likes the M1 T&SUV oil. It feels like the Penz Syn Euro did WITH the SynPower.
