Why is my car leaking oil after an oil change and how do I fix it Are additives a good idea?
Are oil additives a good idea?
To my knowledge, oil additives are a good idea only if you start using them when you buy a brand new and you are the first person to own the car. It is not a good idea to use them with a car you bought, when you are perhaps the third or fourth owner ; car with high miles, not good idea. The vast majority of oil additives are snake oil products. Leave them alone. Change your oil & filter religiously and do not put any additive in your engine.
Can you use oil treatment to old petrol car?

Can you mix 5w20 with 5w30?
Even if you can it's not a good idea. These oils have different viscosity and might have different chemical content. When you mix the oils it can change their mechanical properties and the oil will not be as good as when they are separate. You can get special additives to tune 5w20 in something in between 5w20 and 5w30.
