I was at Hazzman's last night and he got out a new gallon of Injex he just got to try this year. We opened it up and it smells like diesel fuel, no kidding! Does it smell bad for the guys behind you on the trail? Does it smoke much? Has anyone used it with exhaust valves? I used regular Arctic Cat oil that did have a pretty bad smell while running but no smoke. I now use AC extreme it doesn't smell or smoke bad. I'm getting the wife a sled with valves and need a new oil. I would rather spend less on injex than waste it on the new AC oil for valves. Injex is also sold at Farm and Fleet. I will probably be following the wife so I don't want to be smoked out each time. Thanks in advance.
