[Junior]

Latest from the 04 Honda Accord V6. 10,800 miles on the sample, 100,600 miles on the vehicle. Zero make-up oil added. M1 filter. Service dates 1/26/2008 to 7/20/2008. According to BlackStone I have reached the limit with Insolubles(1.0%). They suggest I drop back to around 9,000 miles. Fuel was 1.0% TBN 1.3

Are the previous samples listed with Mobil 1? If they are, Mobil 1 would be a better oil for your engine.

It's a shame that the Amsoil could not make it to 15K! It's close to a 30wt, which I believe it starts out at anyway. If your bent on staying with Amsoil, try the Eao full flow filter.

With Zero make up oil the rings and valve guides are not letting any oil slip by. 100K is about 1/3rd into the engines life. You might try an injector cleaning service to slow the fuel contamination down.

 

[pickled]

Wow that fuel dilution is up there. Insolubles aren't all that nice either. What was your last fill and what were your driving conditions for this OCI?

 

[Pablo]

Fe wear looks much nicer than M1. Considering you have a fairly large fuel dilution problem Fe wear looks great AND the viscosity is perfect.

Fix the fuel dilution problem and your solids will come back down. What kind of air filter are you using?

 

[JSP]

Looks pretty good and better than M1, but I agree with Blackstone in that a 9k OCI looks about right.

Silicon looks really good, what air filter are you using and about how many miles are on it?

 

[FZ1]

Agree you need to reduce the oci and or time in use. These Honda V6's are prone to fuel dilution so you can't typically can't run the oil as long as,say, a Honda 4. Don't ask me how I know. Lol.

LCmanx2 100,000 miles on the car with conventional oil based oils cant be the cleanest engine at the ring pack.
one UOA with 10,000 miles on the oil is not information you can use to make a statement one oil is better than the other.
to make things easier I see four oil samples from the original poster but I am not sure wich oils and at what times did he change and sample

it says 10,000 miles on the oil, what is the other information above?
any oil wont perform it's best for one oil change interval.
this is why it is important to do oil samples to understand more about the engine you are sampling.
remember no two engines are the same.
if the original poster runs the same oil again the UOA will come back better than the last and the chart will show improvement or something else.

 

[The Critic]

100k? The car is due for new spark plugs as part of the 105k service. Replace the plugs with new OE plugs, perform a full valve adjustment and replace the air filter. That should help the fuel dilution.

 

[INDYMAC]

I agree. This UOA tells me that it's time to do some engine and emissions maintenance. I'm surprised that the oil condition is as good as it is.

 

[ToyotaNSaturn]

+2 to what The Critic said. There's too much fuel in the oil so you're not achieving a good reading from the Amsoil product. Fix the fuel problem, drive another 10K on this same oil then resample.

 

[Tones]

Fuel dilution is pretty typical for these v6s. Just doing a tuneup will probably not fix it though it couldn't hurt. Looks like your driving habits might have changed for the past couple of OCI? Oil did a great job despite fuel dilution. Last interval at 9k does look better.

 

[Junior]

Oh, lets see a few questions to answer here.

-The air filter is a Fram 9600 it has about 8,000 miles on it.

-My driving habbits really haven't changed much. I average about 2000 per month. I bought the car in Aug 05 with 30,000 on it. It now has 101,000 For this change the car was driven 1500 miles on vacation before the oil was sampled. 600 out, 300 during the week, 600 back. Oil changed the next day. So much for long tips burning out the fuel.

-The 9300 mile Amsoil run was from Sept 07 to Jan 08 (about 5 months)
-The 10,8000 Amsoil was from Jan to July (about 6 months)
The last two oil samples were back to back. The other two were not consecutive samples. It has had M1, PP and one run of MC in no particular order before the Amsoil.

Yes, I agree it is time for the plugs, timing belt etc. Fuel mileage has been down about 5-8%. I have been treating this car different from others I have owned. I am waiting until 100-105K to do any maintenance and I never let it warm up. I wanted to see if it would make any difference.

As far as the viscosity, I'm a rookie here but my guess is the fuel thinned it down and then later it started to thicken back up to get to 9. See the 7.55 of the previous sample with 1.3% fuel and 9300 miles.

I'll probably back off a little on the OCI miles, especially in the winter. I have enough Amsoil 0W20 for two more changes. Maybe try for 10,000 again next summer. To be honest, it has been hard for me to break my 3000 mile habit and I wanted to prove to myself I could go 10,000. Oh, I don't have loyalty to any particular oil brand.

Just to clear things up. All the data reads from left to right. 4 samples. I listed the oil used, miles used and sample date. I know it is kind of an eye chart.

The first two are M1. However, the mileage is much lower so it isn't a fair comparison.

 

[pickled]

That's why there are rate comparisons...look at ppm wear metals/1,000 miles. Now someone will chime in and say it's not a fair comparison because one oil was stressed by the extended drain...yada, yada, yada.

then, looking strictly at the iron in ppm/1000 miles the Amsoil did better than M1.

 

[buster]

I also agree with the Critic. Fuel is really the issue here. New plugs may help.

Amsoil has the wear advantage among these samples. Vis. idicates a lot more fuel in the oil than should be.

Quote:
9.00 7.55 7.84 9.26


Looks like it lowered the viscosity for the first Amsoil OCI, but for this 10k mile run it's perfect. The M1 5w30 dropped quickly to 9.3 which is low for that oil.

I wouldn't worry too much about any of the wear metals here. They are all within the low range. I'd try and do the things mentioned above then run another 10k mile sample. PP might hold up even better than M1 with that much fuel present.

 

[pickled]

I agree with you there Buster...I just want to make sure that he knows that PP, or any other lubricant definitely would not be wise to run out to 10k miles if he doesn't correct the dilution. UOA's are SO FUN!

 

[Gary Allan]

The elementals are so low across all tests that I think you can skip splitting hairs. The oil condition is the only thing worth looking at here.

Insolubles point to significantly higher byproduct production.

Do the tune and see what happens.

 

[Junior]

Hey, thanks for the discussion. Yes, I noticed the fuel issue. If I don't get that resolved then 7500-9000 is probably a better target OCI with a little reserve if I don't get it changed on time.

So far I'm pretty impressed with this engine.
