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 permanent 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.

4-4.RECOMMENDED FUELS

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.
