last year i picked up a 2005 GMC Yukon Denali 6.0...I went to change the oil and a buddy who was moving said I have 6 quarts of Farm and Fleet full synthetic 5W-30 (the weight recommended for my GMC) and it's yours if you want it...I asked a similar question you asked on this Forum and the responses were similar...all the quart containers were still sealed...
the oil color was the usual light, golden color, the approvals were GF-5 and SN...in went the oil with an OEM ACD filter...about 7 months and almost 4K miles later it was removed and replaced...no issues noticed and appeared normal throughout its use...turned out that this Farm and Fleet oil was oil I bought for my 2000 Escalade back in 2012 and originally gave to him...he never used it...almost 11 years old but in the sealed, quart containers
I bet you'll be fine IF it meets or exceeds the specs/requirements/recommendations for your vehicle...my 2005 GMC came with standard Dino oil so full synthetic of higher approvals worked just fine...
Good luck with your choice,
Bill
