2.3 — Engine Oil Recommendations
To maintain the product warranty, use only genuine Generac replacement parts. Generac maintenance kits include
both the oil filter and air filter, and can be obtained through any Authorized Dealer.
All Generac maintenance kits meet minimum American Petroleum Institute (API) Service Class CD or better. Select the
appropriate viscosity oil grade according to the expected operating temperature. After break-in, synthetic oil also can
be used in the appropriate weight as standard. Once synthetic oil is used, it should be used for the life of the generator.
It is not recommended to go back to a mineral oil. Do not use special additives.

2.4 — Coolant Water Treatment
Use of improper coolants can damage the engine cooling system. Use demineralized water or distilled water for best
results. Hard water causes scale deposits, which reduces cooling efficiency and raises internal temperatures, possibly
leading to engine damage. Use an anti-corrosive to prevent rot in summer and anti-freeze to prevent freezing in winter.
Dilute the anti-freeze based on a theoretical temperature that is 9-18°F (5-10°C) below the lowest temperature
expected in the area. A ratio of 40-60% is most common range.

Coolant (% Volume)
NOTE: Use only Peak Fleet-Charge® 50/50 ethylene glycol type coolant (available from any authorized
dealer).
*
Do not use propylene glycol type coolant. Using the wrong coolant, mixing different types of coolant,
or even mixing different brands of the correct type of coolant, can produce unsatisfactory results, pos-
sibly leading to engine damage.
2.5 — Fuel Requirements
IMPORTANT! DO NOT use Home Heating Oil or Bio-Diesel Fuel.
Use No. 2D diesel fuel when temperatures are above freezing. When temperatures are below freezing, blend No.1D
diesel fuel and No. 2D diesel fuel together for a climate adjusted fuel ratio.
Starting October 1, 2010, diesel fuel must also meet the following requirements:
• Sulfur content of 15 parts per million (ppm) maximum.
• Minimum Cetane index of 40.
