Interval included a trip to Orlando so gas in GA & FL as well. Regular 87 octane gas every fill-up.

No oil adds.

Oil was replaced with more RLI 0W20. Oil filter was changed with another AMSOIL EaO20.

Viscosity is great. Antimony is off so I wonder if there has been a formulation tweak? Wear is way down. Consumption is down as well. I think it looks good.

EGR code P0401 was fixed during this interval by cleaning intake manifold off of car with chlorinated brake cleaner & forced air dry. AMSOIL Powerfoam couldn't cut the carbon buildup last time. Code is gone & intake looks excellent.

I plan on going 7500 miles next interval just to be sure everything stays fine.

Why is your lead so darn high! That was a huge spike when you first went to RLI and the second run is still high but not insanely high! This is not the first high ester oil in this thing the Redline did so huge cleaning already and I would think that Amsoil did not leave much behind and this is the second run on RLI so I do not see where this is still cleaning. Normally if I saw lead that high with all the other wear metals being low I would say the viscosity is too low and the crank is not being properly floated or wedged away fromt he bearing shells! IF RLI does not get you nice single digit to zero lead numbers by the third run I would right it off as an oil not for your engine! Go back to Redline run it three times and then do a UOA and watch how preety it looks.

RLI is too expensive for the results Ihave seen since I have been back on. I am not partial to vegtable oils in crank case's for the most part. Reacted esterfied Castor oil being one of the few I like. For themost part I think vegtable oil has a ways to go yet before it is ready to use in cars especialy if one wants once a year long drain intervals. I do not think think RLI is esterfied at all is it? Arent they useing none esterfied vegtable oils??? I am asking not making a statement.

In fact I am not sure if I would even go with Redline this engine does not really need it! In fact I am betting that M1 0W20 would turn in a better UOA then this RLI and it is far cheaper!

+1 The more I read about it, the less I like it. For the high cost of this oil there isn't really any great benefit to it at all. JMO

Fixed your comment. AMSOIL Powerfoam from a previous attempt at cleaning due to the P0401 EGR code. The rest of your comments & the conclusion you reached is in error due to you not knowing this since I typically don't post comments about previous oil runs. Comments on previous oil runs are on here.

All of these results are from the 2nd OCI with the particular oil. Look at OCI mileage & total mileage to see that.

What leads you to that conclusion? It's not anything in this UOA. Nitration is higher than desired sure, but that is not due to the oil but rather what the oil has to put up with. The viscosity is pretty much dead nuts with results out of the bottle. TBN is holding up great with acid increasing 1 point. Iron, copper, and aluminum are all very low. I'm confident that lead will continue its downward trend in the next cycle.

I do have a question re your fuel. I have an 02 V6 also and my oil progressively smells like gasoline over my oci. Does your V6 oil smell like gasoline? Trying to quantify the magnitude of my fuel dilution. Thanks.

JMO that's all. I've seen some nice UOA's with less expensive oils, and the lead is still high. Maybe it was the Power Foam, maybe it wasn't, time will tell on that. Still interesting, and thanks for posting. No disrespect intended.

 

[Jon]

I had an '02 Accord with a leaking fuel injector.
An oil analysis confirmed high fuel in the oil which, eventually (had to be insistent but polite) they eventually found a leaking fuel injector. The first couple of tests they ran (leakdown test, etc... ) didn't show a thing.

Subsequent to the replacement, the car ran better, idled better, and no more fuel in the oil (well, no more than the *usual* high dilution these get...)

Thanks,man.

Yeah ..the price:benefit ratio here is a challenge. More than most of us will entertain.

Well, let's think about it a bit. If it was a true mechanical issue, going from 180+ to about 10% of that reading is unlikely. Now maybe if he had used a good percentage of leaded fuel and stopped, that would work ..I suppose.

Now if we kick out a mechanical issue of that magnitude ..what are we left with? Literally this would be one of those "did you do anything different? ..yeah, I sneezed ...THAT'S IT!!!" kinda thing. Whatever introduced that massive dose of Pb just isn't there anymore.

 

[benjamming]

Gary,

I introduced PowerFoam last interval that caused the spike in lead. No leaded gas, that's for sure. Ha!

 

[Gary Allan]

That's got to be the source. Do we have any other powerfoam UOA's out there

I'm trying to determine if the product has the Pb in it (that's a whole lot of Pb) or the use of it smacked around your crank with misfires to bang out all of it (not as likely, but possible, ..and that's still a whole lot of Pb).

The decrease discounts just about all the usual suspects. You can't say that it's a particle streak since that would leach for many more miles (imo). You obviously removed all but a fraction of it by changing the oil.

 

[benjamming]

Not sure what solvents are in PowerFoam, but they hit the bearings and strip that layer of activated metal additives from motor oil and react. Once that micro layer of chemistry is in dispersed suspension this is the result.
