Briggs & Stratton 2PK Vanguard 15W-50 Full Synthetic Heavy Duty Engine Oil - 5 Quart (100170) - Ideal for Lawn Mowers, Tractors & Outdoor Power Equipment

This review is more about the seller than the product. I bought this oil for a new zero turn. On my order one container was damaged during shipping. This stuff isn't cheap, so I was a little disturbed. However, after contacting the seller, a replacement was quickly shipped out. Honest sellers deserve loyal costumers. I'll be using these guys from here forward. Good products, fair price, great customer service.
