Just bought a new Suzuki 20hp 4-stroke outboard.
Oil suggestions?
vendor recommended any 10w-30 or 10w-40. Also stated to use STP fuel treatment and mid-grade fuel (reduced ETOH).
What are the thoughts here? (I’ve been running No-Ethanol 90octane in ALL my power equipment: saws, boats, generators, lawn mowers).
Any reason to NOT use a synthetic such as Mobil1 or Castrol ?
