[Redneck53]

Hi all, Long time since I had anything worthwhile to post. Actually, I've been working like a dog and have not had much time for cyber-loafing. The car is my daily driver, goes 50-60 Km daily, and sees aprox 80% of that on the hwy at 95-110 Km/hr. In this report, my main concern is the silicon. The reason may be that the intake manifold was leaking and I had it replaced about 2 months after I changed the oil. I had asked for the MOB II analysis, but the TBN wasn't reported. I am addressing that with Wearcheck and will post if they can get the TBN. anyhow, here are the results. The detail is as follows:

1st number is RL 5W 30 with 10,315 Km/6 mo
2nd number is RL 5W 30 with 10,000 Km/6 mo
3rd number is Green GC M04 lot with 13,116 km/7mo

So the manifold was changed during this last oil cycle and the oil not changed? Obviously lead is high. Silicon goes with leaking manifolds. Doesn't seem to contributed a lot to iron/Aluminum wear.

 

[Blake Sobiloff]

You lead counts are headed in the right direction, but your silicon counts continue to increase. Replacing the intake manifold may have eliminated the dirt ingress, as the dropping lead would indicate, but I'd revert back to a 3K OCI and analysis regimin until you see the silicon start dropping, too.

 

[T-Keith]

Lead seems really high, silicon is pretty high. So when was the intake fixed before or after this sample was taken?

 

[Redneck53]

The manifold was replaced before the sample was taken. Sequence of events were as follows:

End Feb 05-Replace oil
Early May-Replace manifold
Mid Sep-Sample oil

Patman. You deal with the Wearcheck in Mississauga. Have you ever ordered a MOB II nanlysis and not got the TBN. I still have not heard from Gloria, so maybe I'll give her a call.

Cheers all

On my last report, which was an MOB2 package, they didn't run initially run TBN for me either. I had to specifically request it, but they sent me a note afterwards saying TBN was for diesel engines and TAN was for gas engines. WTH? They'd never said this before. I will be sure to always write in on the comments section that I want TBN to be run with my tests.

One thing you can do the next time you send them a sample is check your status online via www.oilanalysis.net

It will show you which tests are scheduled for your sample and which ones have already been completed. If you notice something missing you can add it at this point too. (keep in mind that some of the tests are extra cost, such as if you requested the pour point for example)
