SERVICE BULLETIN
Subject: 2-stroke engines - running in and oil requirements
Tecumseh now requires that all 2-stroke engines with a recommended fuel/oil mix
greater than 25 : 1 should be run with the first tank of fuel mixed at double the
recommended ratio. This gives increased protection during the piston ring seating
process.
We also highly recommend the use of Tecumseh smokeless oil (part number
26980003), which is an extremely high quality and environmentally friendly product.
The use of alternative oils which may be of a lower quality will invalidate the warranty.
