Titan 0293943 PowrLiner 850 Gasoline Engine, 37.7CC
Use automotive gasoline that has a pump
octane number of 86 or higher, or that has
a research octane number of 91 or higher.
Use of a lower octane gasoline can cause
persistent “pinging” or heavy “spark knock”
(a metallic rapping noise) which, if severe,
can lead to engine damage.
