For anyone that is using old engine that is not overhauled, but shows slight oil burn and some white smoke. Suggest you find and use Revo 20/50 on your next oil change. This oil almost cured my white smoke problem. Have been using Castrol 20/50 that almost eliminated the problem. But Revo almost cured it. 4L pack is less than RM100.

This is only for old engines that has some oil burning issues.

Forgot to take picture of the packaging. The picture in the internet is not that packaging. I think it is mineral. It worked for my old carburetor Corolla 1.6 engine. 

You can try adding in Liqui Moly Motor Oil Saver 300ml.
