Weight of oil in Taurus

I recently got a 2001 Taurus and put 10-30 oil in it. I see on the filler cap I should have used 5-20. In the past I won’t have thought much about using a different weight but my neighbor said it might make a differenc because cars are built differetly now. Am I okay to drive and then put 5-20 in next time or can I ruin something by leaving the 10-30 in.

Thanks

Cars are made different now, but leave the oil in until the next change. If you have to add oil you can top it off with 5W if needed. 10W-30 won’t hurt anything for one oil change interval of 3 to 5K miles.

Not a problem but use the proper oil the next time. The difference in 5W-20 and 10W-30 is not that different in moderate temperatures. It can be though if you live where it’s extremely hot or cold.
