The O.S. Max 30VG (P) ES Electric Start, Rear Exhaust
Monster Truck Engine with Pilot Type Crankshaft.
Advanced Bi-Metallic Liner (ABL) cylinder liner construction
This process uses a double layer of plating material rather than one thick layer.
This helps the metal bond to the cylinder and is more durable.
Also, the plating process is more consistent, resulting in a more precise fit
between piston and sleeve for better compression and longer life.
Machined aluminum piston, 3-port cylinder liner and double bushed knife edge
connecting rod 21E single needle
Slide Valve Carburetor with insulated sleeve to prevent fuel vaporization
SG (pilot) type oversized crankshaft with rubber-sealed front bearing and
oversized rear bearing to handle high torque loads

Most of the fuels we carry meet or exceed the lubricant content required for
optimum performance and maximum engine life.
In the past, the conventional lubricant content used in fuel was 18%.
But with new advanced technologies, fuels like Red Alert and O'Donnell for
have a better quality of lubricants even though the percentages of lubricant
content are lower.
These high-tech lubricants provide exceptional cooling and protection.
