What kind of fuel do you use in a lawn mower?
Fuel for your lawn mower or outdoor power equipment must meet these requirements: Clean, fresh, unleaded. A minimum of 87 octane/87 AKI (91 RON); If operating at high altitude, see below. Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable. The best answer, for most home lawn mowers, is to use fresh, regular unleaded gasoline with a minimum octane rating of 87.
Can I use 5W-30 oil in my petrol mower?
Engines on most outdoor power equipment operate well with 5W30 Synthetic oil. For equipment operated in hot temperatures, Vanguard 15W50 Synthetic oil provides the best protection.
