Kirkland Signature 5W-30 Full Synthetic Motor Oil 1-Quart, 12-pack
The Kirkland Signature motor oil indicates on the back of the bottle indicates "For use in gasoline, flex fuel or gasoline-electric hybrid vehicles requiring SAE 5W-30... Approved for use in all GM gasoline engines requiring dexos1 Gen 2 5W-30."
There is no mention of diesel engines here. I own a 2014 VW Passat TDI. Can I use this motor oil?
Does anyone of experience with this oil even for unleaded? Would you recommend it?
Thank you!

Check the API service specification that your diesel engine requires.
Thank you Chuck. I took a look at the table, but I don't think I have the level of experience necessary to properly interpret it. Do you have any advice for a 2014 VW Passat TDI?
I'm not familiar with that vehicle but the owner's manual should state what API grade of oil is required. If you don't have and can't find an owner's manual you try calling a dealer and maybe they'll give you the correct answer. Looking at the API chart it appears to me that you need a CJ-4 or CK-4 oil but you should verify that.
Addendum: I see in another response that your owner's manual states you should use "VW 507 00" specification oil. If you search online you will find oils meeting that specification.
The manual states: "Engine oil specification: VW 507 00"
How does that translate to an API standard?
I have no idea but as I said in my edit above if you search for that specification you'll find oils that meet it. They seem to be synthetic oils labeled for European specs.
Check this please -
If Kirkland oil is not on this list, it's probably not approved by VW for the 507.00 standard.

@doc, that link is for your own computer (local C: drive). I think you probably meant to provide a link to a file sharing site.
Yeah, thanks. I tried to just copy the web address and it just downloaded the file and I haven't figured out yet how to do a file sharing sight. My pc came with a manual choke and a rope stater, so did I.
Heck, I'm using a descendant of the Unix systems I started with over 40 years ago. Check some of these file sharing sites:

For my personal vehicle, I use 5w30 in the cold weather and 10w40 in the warm weather as per my owners manual. This is not a diesel engine though.
Read your owner's manual to know exactly the weight and grade of engine oil your vehicle requires.
Thank you Doc. Here is what the manual states:
"Your engine was factory-filled with a high-quality, “synthetic” all-season engine oil that meets strict
Volkswagen oil quality standards and has a viscosity grade of SAE 5W-40. or SAE 5W-30. You can
use this oil for normal driving in all temperatures.
If you need to add oil between oil changes, use only a high quality oil that expressly complies with the
Volkswagen oil quality standard specified for your vehicle's engine:"
Engine: Diesel engines
Engine oil specification: VW 507 00
"At the time this Manual was printed, the engine oils available in the U.S. that meet these Volkswagen
standards are “synthetic” oils. This does not mean, however, that any “synthetic” engine oil will meet
Volkswagen standards. Always use an approved oil that expressly complies with the Volkswagen oil
quality standard that applies to your vehicle's engine."
How do I know if Kirkland complies with VW 507 00?
Since the manual states 5W-30 or 5W-40, which one would be better for engine longevity?
