Well gentlemen ..can we use engine oil ..or do we just agree to differ on expert advice?

I would have thought car engine oil these days is to a very high standard particularly considering the value of say a luxo BMW or Merc car engine compared to a relatively cheap 4 stroke lawn mower engine. {anecdotal..not scientific comment}

Specifically has anyone actually encountered damage caused by engine oil. At this point I use B&S oil in the Murray ride on but I am tempted to use my leftover car oil rarther than throw it out. .

Also can I use engine oil for 2 strokes ..we always used this in the Victa when I was a kid. ..the engine kept running normally.
My Father used the Victa for employment for a number of years ..I never heard of any issues ..{maybe it was falling apart inside and I was just not aware..?}

I must admit I used engine oil in my victa's current fuel supply because I had run out of 2 stroke oil ...seems to run ok although maybe a little more smoky than normal. I will revert back to 2 stroke oil on next refill of fuel all the same.
