Can I safely mix these two oils in my snow blower? I have a little bit of Pennzoil 5W-30 made with natural gas and another Pennzoil?
Update:
5W-30 that has no gas in it apparently.

Probably wont hurt the engine. Do not mix regular oil and synthetic. Check to make sure they are the same weight. If the manual calls for 5W-30, Don't mix it with straight 30. It will be too thick on startup on a cold morning.

As long as their both petroleum grade oil yes. If one is synthetic then no.
