Delivers commercial-grade protection and outperforms conventional oils. Tough formulation protects against wear, heat and carbon deposits. Helps maintain power and promotes long engine life. Specifically designed for maximum equipment dependability. Service life up to 200 hours.
I used conventional petroleum oil for the first 5 hours as recommended by the engine manufacturer and then switched to Amsoil Small Engine Oil. After running the mower for another 10 hours I note the following - the oil still looks new; there appears to be little or no oil consumption; the engine seems to run cooler and smoother even though the weather is warmer. Time will tell if this keeps up. So far I rate it 5/5.
I use this in my commercial mowers. Hundreds of ours so far. I personally would not go over 100 hours on any oil unless you have a separate oil resuvuir.
All in all, this oil takes a beating and has I think made up the difference in price from cheaper oils.
