Gm Oil Filter And Castroil?

[bbohannon]

I just purchased a 2011 Sierra and with it I get oil changes for $10 for the life of the vehicle. My dealership uses dexo approved Castroil synthetic oil and GM oil filters. Is this a good combination? For $10 I really can't complain but I would still like to make sure the oil/filter are of good quality.

As long as it's Dexo approved, it will be fine

 

And congrats on the new truck.

Castrol is not dexos approved nor is it on GM's approved list. Castrol may say it meets the dexos spec, but that is different. However, if this is a GM dealership that is putting it in your 2011, make sure you get documentation that THEY put it in during each change and keep that documentation. That way, if something ever happens and GM tries to deny your claim, you have proof that THEIR representatives are the ones who didn't use a dexos certified oil.

There's definitely nothing wrong with an AC Delco OEM filter and there's nothing wrong with Castrol (other than I don't like to support BP) and I'm sure their synthetic would be more than adequate as they claim to meet the dexos spec, but if the unexpected happened and you were in a "discussion" with GM the dealer paperwork would sure be handy to prove the DEALER didn't use the approved dexos stuff.

What are the guide lines as to the oil changes? Every so many months or at what mileage? That is a good deal.

The dealership told me it was dexo approved but sure enough it's not on the list. Thought that was interesting.

 

I get the oil change on the truck whenever I want it as long as I'm the owner. Thought it was a good deal myself If I want to use Mobil 1 synthetic it's $90

I think you need to report the dealership to GM for not using Dexos Approved oil. After all if something does happen and you have to go into another dealership and they determine the damage was oil related, you are SOL, even if you show them proof that a GM dealership changed the oil. Needs to meet the MANUFACTURERS Standards, not the individual dealers. If it's not on GM's list, it does not meet the standards according to GM, regardless of what it may or may not say on the bottle. Some of the high premium oils out there claim to meet the standards, but are not certified by GM. Until your vehicle is out of warranty, you sure as hell better be using what GM says you should use.

 

The AC/Delco is a good quality oil filter too, nothing wrong with using that at all.

Wholeheartedly agree, but not to highjack the thread I know there's some discussion about the e-core designed AC filters on bobistheoilguy.com. I personally haven't seen a PF48 with the ecore design, but personally if I do run across one I think I'll opt for the traditional metal center tube design. If Delco goes all ecore I'd suggest a Wix, Napa Gold, or Purolator Pure One. By the way the AC filters with ecore design have an "E" after the part number.
