WAKO'S Engine Oil 10W40 4L Can is new and unused. I purchased it at a motorcycle shop in January of this year, 2026, but I wanted to try oils from other manufacturers, so I kept this stored indoors. since there is still time until the next replacement, I have decided to list it. It is still new and unused. Thank you for your consideration. In addition, to prevent trouble, we do not handle requests for dedicated listings, and we will proceed with transactions with those who have completed the purchase and payment, even if there are ongoing comments. We appreciate your understanding.
