Can i use lawn mower oil in car engine?

You mean its not a good idea to use garden oil? Are garden oils the same as automotive oils or are they different? Additive wise and so forth.

I would Ignore this as his comment is unfounded.

Just curious, I did not look up the specific details of the garden oil, is this a detergent or non-detergent oil? Many of the small engines use non-detergent oils. On a frequent enough OCI in a car engine it probably is OK, but I think detergent oils are a much better choice. Also agree that even the modern synthetic blends are very good oils for relatively low cost.

Here is info of the Mobil garden oil that i have been thinking. It says it meets the SJ spec, so for an engine requiring at least SG, i think that might work, but im not sure since its "garden" oil. 🤔

Mobil™ Garden Oil 4T is a multigrade SAE 10W-30 engine oil designed for 4-stroke garden machines.

The oil you linked to from Mobil, I'd have no worries about running it in your old car. API says SJ is good for 2001 and older engines. I also would run a synthetic too if that's what I had on the shelf.
My only concern would be -20C or lower starts, as a -36 pour point isn't great. If you are doing lots of -20C starts then I'd look for a 5W30, to be easier on oil pump and starter, and to help get the engine lubricated quickly.
