Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I use this in my 2012 Evinrude 250 HO E-Tec. Have never had any issues with the motor. This oil is a little more expensive than other 2-cycle oils, but the small premium in price is worth knowing my motor will perform optimally. I recently had an issue with a damaged shipment that leaked in its packaging. I notified LEADERS RPM and they promptly sent a replacement. Great product and great vendor.
