So I was messing around with the Traverse today and noticed on the DIC that the oil was at half life or "50%" so I pulled out the dipstick for a look. The oil has 3300 miles on it. This isn't my dipstick, but it could be.....

I have 30+ years running Mobil 1 almost exclusively across many different platforms and I have never seen it get this dark this quickly. ( Currently 8 vehicles) My son drives a 2002 Silverado with 340k miles on it. He services that truck about every 8k miles and his oil isn't much darker at that OCI and he works that truck too. The BWM gets 0w/40 Mobil 1 Euro oil, that stays amber too..... at the same 8k OCI.

I keep reading how hard these new multi valve, multi chain, D.I. gas engines are on oil, and how new specs need to be developed to cope with them.... and I'm suddenly a believer.

GF-6 is the oil to keep an eye open for. Until it comes out, I'm prolly going to service the Traverse every 5k miles which will be sooner than the DIC says too....... Lets all hope the GF-6 oil does better.

Some engines dont care if you use synthetic oil of not, as long as the Dino oil meet's manufactures spec's, your good to go. The GM High Feature V6 does seem to need synthetic oil.... period. For those who have had timing chain or cam phaser issues when running Dino oil, I can see why. Even changing it at the DIC intervals may not be enough. Someone posted dealers do a recalibration of the DIC to help the situation. If sticking with Dino oil, even that might not help to keep the issues away. These are the 7 new tests the GF-6 oil must pass......

I found it odd that "IVD" or "Intake Valve Deposits" are not one of the test parameters....... strange.

Yup you are seeing what @rbarrios has been preaching the whole time I've been here. Full synthetic oils with shorter intervals than the manufacturer recommends.

I looked around for some photos of a PF64 cut open. Here they are, and it clearly has a bypass valve. My PF63E did not. It appears there is allot of deception going on in the Delco filter supply chain. Reason # 764 to walk away from it.

I keep my eye's peeled for things that either confirm, or disprove, my train of thought. I'm not a huge fan of OEM oil filters. Nearly all are made by a 3rd party who won the contract with the cheapest bid. Here's a failed PH 64. I'm glad I dont use those on my Traverse......

Did the 10k mile service tonight...... everything looks great. Oil has 5200 miles on it. The dipstick was slightly below "FULL" Maybe a pint low. Something to keep an eye on.

The magnetic drain plug is nearly spotless. I had to really zoom in on it, to see anything. When I wiped it off on a clean paper towel, it only left little smudges.
The Amsoil filter has been slightly redesigned. It used to be a glossy black finish. Now its a rough "Shark Skin" kind of texture, It's a nice addition .

I switched to the new spec GF-6 oil for this service. Pennzoil.

$21.97 at Walmart at 5k OCI's equals about $80 a year in oil. The filters are $15 and will go 10k miles each so that's another $30. $110 per year for 20k miles of driving, is money well spent.

This tool makes filter changes effortless.....It fits well between the radiator, and the catalytic converter

Lifetime Service numbers are as follows....
Miles- 10,450
Ave. Speed - 33mph
Ave MPG - 19.7

Last Service Interval
Miles 5200
Ave Speed - 34.5 mph
Ave MPG - 19.9

The numbers are nearly identical. That will be useful to compare the old GF-5 spec oil to the new and improved GF-6 oil I used for this go-round
