Chicago → slowblower repair / tuneup near elmhurst

I have an old two stage snowblower that runs but I want the oil changed etc. the model came with no dipstick, just a plug.
I'd like to upgrade it to the dipstick. it's an old aries.

I can't vouch for the place as it's new (to the location at a minimum) but there's a place that opened on St.Charles in Villa Park. South side of the street about a block E of Westmore.

It moved this summer in when a motorcycle dealer moved closer to 83.

I think there is also one 5 or 6 blocks further E also on the South side of the street.

I don't know the names, but can grab them tomorrow as I drive past if you need.

if you can it would be helpful
thanks!
