4 - FUEL AND LUBRICATION
4-1. FUEL
Use regular grade unleaded gasoline mixed with Genuine
Factory Parts 40:1 custom 2-cycle engine oil for best
results
. Use mixing ratios in Section 4-3.
Never use straight gasoline in your unit.This will cause
per
manent engine damage and void the manufactur-
er’s warranty for that product. Never use a fuel mixture that
has been stored for over 90 days.
If 2-cycle lubricant other than Genuine Factory Parts
Custom Lubricant is to be used, it must be a premium
grade oil for 2-cycle air cooled engines mixed at a 40:1
ratio. Do not use any 2-cycle oil product with a recommend-
ed mixing ratio of 100:1. If insufficient lubrication is the
cause of engine damage, it voids the manufacturer’s
engine warranty for that occurrence.
4-2. MIXING FUEL
Mix fuel with Genuine Factory Parts brand 2 cycle oil in an
approved container. Use mixing table for correct ratio of fuel
to oil. Shake container to ensure thorough mix.
Lack of lubrication voids engine warranty.

Some conventional gasolines are being blended with oxy-
genates such as alcohol or an ether compound to meet
clean air standards. Your MTD engine is designed to oper-
ate satisfactorily on any gasoline intended for automotive
use including oxygenated gasolines.
4-5.CHAIN AND BAR LUBRICATION
Always refill the chain oil tank each time the fuel tank is
refilled. We recommend using Genuine Factory Parts
Chain, Bar and Sprocket Oil, which contains additives to
reduce friction and wear and to assist in the prevention of
pitch formation on the bar and chain.
