I think the key is to tie Ashley's character as an oil tycoon with the "extra quality" aspect. Maybe the feature is a premium product line with additional benefits, like a warranty for performance, or a unique application in a niche market. Alternatively, a feature could be a loyalty program for her customers where they get discounts or early access to new products, which reinforces the "extra" aspect through exclusivity.

Alternatively, maybe an online platform where customers can track the source and production journey of the oil, emphasizing transparency and quality. Since she's an oil tycoon, maybe a feature called "Transparency in Production" where each batch has a story.

If the oil is "extra quality," perhaps the feature is a line of high-performance lubricants or organic, non-toxic oils. Maybe Ashley's Extra Quality Oil is used in niche markets like high-end cars, aviation, or medical equipment. Or she could have a feature like a custom-blending service where customers can choose their oil specifications.
