This is my 2006 Hummer H3. This oci was Valvoline synpower with mobil 1 filter. I am now back to pp and ACDelco like I have ran in the past. Even though wear improved I am thinking about taking a thousand miles off this next oci.

Looks good!

Question though, did the H3 not ever come with the I5 engine? I thought they did.

 

[raptorman53]

They do. They put the wrong average's on there for the second time. When I get the new copy, I'll post it.

They come with either an I5 or 5.3 V8. The early I5's were 3.5L and the newer are 3.7L. They never came with a V6.

Another very good UOA with Synpower. And and it looks like this OCI might be just the right length given the TBN was below 2.

 

[cp3]

Was this changed based on the OLM? What was the reading?

Tbn of 1.4. Oil is done. Synpower's Tbn retention is a bit weak IMO. I've also noticed higher Fe with Synpower compared to their conventional oils. Same can be said with conventional Mobil oils vs Mobil 1.

Metals PPM are fine as they are pretty much meaningless anyway, but Valvo in this engine seems to have reached it's peak at 7500 miles. If you are interested in longer OCI switch over to M1 5-30 or 5-30EP. and you'll be good for 10-12K.

I changed it based on mileage. The OLM was at 33%.
