Is the lubricant business easy to do?

Depending on the direction you're going. Acting as an agent or a retailer? The agent wants power and money! More profitably, retail depends on your strategy, the location of the store and other supporting products. The products are too single to do business, and the reputation is good. It's good to be an agent. The risk is small, but it depends on your strength. I hope people let you act as an agent!

The brand depends on where you make it and the local people's consumption price of lubricating oil. If the local consumption level is high, you can be a famous brand, and vice versa!

You must study the market well before you do business, so I won't say it here. The market still has to study on its own, so that it can be true. You can gain experience yourself!
