Just bought the troy bilt 'blower with 5.5hp Tecumseh. Manual says
5w-30 for cold (~40F below) and 30w for above 40F . After it runs for
a couple hours I'm putting synthetic 5w30 in it and dont expect any
problems.

Hello:

Gets cold here, but nothing like Minn. or N. Dakota !

Ariens site is down, and can't find the Tecumseh Manual that I once had.

For their typical 7.5 H.P. Snowblowers with the Tecumseh engine, what's the
correct oil grade, please ?

5W-30 ?

Thanks,
B.
