Does anyone knows if engine oil additives such as lucas or any others are good or bad for our engine? I tried to Google it and still am not sure.
Neither. They are not good or bad for the engine. They are however a complete waste of money and bad for your wallet.
Most engine additives are not worth the money.
Rarely. Such additives should only be used if your have a known sludge condition within your engine. Otherwise, they are a total waste of cash.
