A friend in the tree trimming business recommended this to me years ago. He uses it in saws, trimmers, mowers, small outboard etc. He likes that he needs just one gas can on a job. 3 years ago my dad started using it so that he could have one gas can for the mower, snowblower and 2 hp outboard. Yesterday he bought a supply of it for the winter. The salesman told him never to switch to another brand of oil after using the Opti 2, as the non Opti oil will ruin the engine due to insufficient lubrication. I have a hard time believing this. Is it possible? Have any of you used it? The website does seem rather snake oil like.
