Good oil, can’t beat the price. Had no issues receiving them when just the buckets were sent. Now having leaking issues in transit because they are being put in a box, so the buckets are getting laid on their sides and leaking out. If Amazon is reading this, please send just the buckets. UPS/FedEx knew to keep them upright and we didn’t have any problems.

This is a really good buy. The only place I could buy synthetic 50W locally was at auto parts stores, and then only in quarts, which is really over priced. This a much better deal.
