How do I choose the best lubricant derived from hydrocarbons for automotive applications?

I visited an auto parts shop to ask about hydrocarbon-based lubricants for automotive use two days ago. I wanted something reliable for my car engine. I also wanted something that protects parts during long drives and hot weather. But when I checked the products there I felt confused. Some lubricant bottles looked premium but had very high prices. Some had many technical words that I did not fully understand. Some sellers kept recommending different viscosity grades and different brands. I could not trust them. I could not decide confidently.

Then I visited another shop in the same area. Some lubricants looked better for heavy driving conditions. Some were made for fuel efficiency and smoother performance. Some still had confusing labels and mixed recommendations from mechanics. I remembered I once used a cheap engine oil because someone said it was “almost the same” as expensive brands. After a few months my engine started making strange sounds during morning starts. That made me hesitate even more.

To check more variety and options while scrolling many online marketplaces including alibaba I found many hydrocarbon-based automotive lubricants. Some products focused on heat resistance and engine protection. Some had synthetic blends for longer performance. Some websites explained viscosity ratings and compatibility for different vehicles. Car forums and review pages also shared real experiences from drivers and mechanics. Some products looked affordable but risky. Some looked expensive but more trusted by long-time users. There were many choices available online. This made me excited but also confused again.

Now I am thinking should I spend more money on a trusted lubricant brand or test a cheaper option first before making a final decision for my car?
