That’s a good point, less cost when you’re talking $23 a gallon vs around $40 for 4 quarts, if bought at “full” price. I keep my eyes on eBay and picked up my last 6 quarts of 4T for $6 each shipped last winter.
Looking at the Walmart website, 15w50 is now in new packaging as an “Advanced Full Synthetic” with the 10,000 mile protection guarantee. Don’t recall my last jug having the 10,000 mile “guarantee” so maybe they’ve bolstered something or it was capable of that but they didn’t advertise. Not advocating 10,000 miles in a motorcycle shared sump with a bike such as mine that has a 5,000 mile OCI, however maybe there’s something that goes along with that new guarantee, that would make the shift quality hang in there a bit longer.
