They do have a 0W40 but it is only CG-4.

Rob_Roy - At home my truck is in a heated garage, at work it is outside but plugged in for 3 hours before starting. The 5W40 has been great, I think the coldest I had to start it not plugged in was -24C (-11F) and I had good oil pressure right away.

Hello. I have a new to me 2009 Duramax with 45,000Kms. All winter I have been running T6 5W40. Just wondering if I should switch to Rotella 15W40 for the summer months, or keeping with the T6 5W40 is fine? In the summer I will be doing some towing, but nothing really over 4000Lbs. I have easy...

Operating conditions would be considered extensive idling and short trips. DFP is still installed and truck would be considered "stock". Oil was changed only because I sell the stuff and I like changing oil! Next time will be an 8000km OCI. OLM read 67%

2K2AcuraTL, Thanks for the reply. I will have a UOA for PP posted early this week. I was happy with the PP, no real start up noise, and as you mentioned, the oil on the dipstick was still a golden color after 7500kms (40% or so on OLM) I did another fill of PP as I had enough for it. Can't wait...

Hello, Trying to choose between PP 5W30 or Esso XD3 0W30 for a 2007 Envoy with the 4.2L engine. We see a lot of cold winter weather but I'm sure both these oils do well in that. Anyone know if these inline engines like a heavier oil like XD3? Thoughts?

I got a call back from a fleetguard rep today. The LF16104 does have a different media than the LF3945 but the lady was very specific that the media in the LF16104 was not "stratapore" but rather a "glass matt" or something like that. I asked her to email me the spec's on both filters. Going off...

Does anyone know the difference between the LF3945 & LF16104?

I'm on the fence between PP 5W30 or Castrol 0W30. Winter is coming, the worst this OCI is going to see is maybe -20C the next one will see the worst of Canadian winters where it will be -30C some nights... Thoughts?

Sorry, I guess that my post was a little deceiving. I don't actually shake the oil for one hour with a machine or anything, I just physically shake them by hand before I start an oil change (maybe 10 seconds each) then about an hour later after things have drained I pour in the new stuff. The...
