Harvest King Synthetic Oil Review

A big chunk of your car’s maintenance service is an oil change. Whether it’s you or the trusted mechanic who will perform it, you will be given a couple of choices for your engine oil: conventional (regular), semi-synthetic, and fully synthetic.

It’s not that difficult to define the difference between the three. But if you’re out there to treat your car like royalty, you would likely go for fully synthetic.

Conventional oil is widely used by car owners as it gives sufficient lubrication performance to your engine without cracking your savings. It’s a decent deal. However, having a synthetic provides better performance and lasting protection to your vehicle – which also leads to bigger savings in the long run.

There are a lot of popular synthetic oil brands that you can see on the shelf. You have Mobil, Royal Purple, Shell, Pennzoil, and Valvoline to name a few. While these products no longer have to prove their credibility and performance, there are also brands that keep it low-key – but still offer quite acceptable quality, just like Harvest King.
