Oil change every 1000 cycles or every year I was told.
The service is every year on my machine. It is the 42 inch table top model made by Sipromac. Made in Canada too. But way more money than the others discussed in this thread and I wouldn't own it if it weren't for the business. I'll recover the capital outlay in time. I'm using 5mil bags with the longest ones being 27 inches this year. My machine also has 2 sealer bars, one at each end of the chamber. The same model is available with a third bar along the front.
I eat most of my tuna raw, some seared, some cold smoked and some canned. The home caught canned is real good and it brings back the memories of the trip too. Lots of tuna sandwiches.
Haven't tried the retort bags yet, so far I like the look of jars on the shelf better than foil bags.
