Bel Ray Lubricants SI7 SYN 2 STR OIL 1L Engine Oil Si-7 Synthetic 2-Stroke Oil - 96030-BT1LC

Bel-Ray Si-7 is great oil for older 2 strokes with auto-lube injection. It's synthetic.. less smoke than conventional oils and has a great smell to boot. I love it for my 74 Yamaha DT360, but the prices can be crazy. It's truely unbelievable what some places charge for it. Keep in mind that it retails $16.99 and can be had for less than that if you do some research.
