If it knocks all the time, it needs repaired. If it knocks when you accelerate, you need a higher octane fuel. Use only the oil recommended by the maker and listed on the oil filler cap.

Sometimes changing the oil viscosity is appropriate. Especially if you know what you r hearing or doing. ( that's only if you really know ) maybe your friend is a mechanic. If not, call the tow truck and have it towed to ur real mechanic to diagnose the problem.

Knocking or tapping? Lifter make a more tap like knock. Big ends make a heavier knock. We can try another oil but normally when a lifter starts to rap it needs replacing. Check it is not big end as far more serious. A mechanic is best here.

Knocking and tapping are two different cases. I would think you are saying tapping, which means that the valve lifters are making much tapping noise. Using a thicker oil may help, but a 10W-20 oil is too thin for the job. Try selecting 5W-40 or 10W-40 grade oil. Knocking is a term used when there is misfiring due to incorrect fuel-air mixture.

If it is knocking, have it checked by a mechanic. The engine is about to break on you soon. Putting a different oil will not do anything to it.
