Hi\r<br>\r<br>I hope you find this video useful. I have tried to explain the meaning behind the codes you find on the engine oil containers. It basically explains their meaning and why they have been given their particular codes.\r<br>\r<br>Codes may include 5w-30, 10w-30, 10w-40 or 15w-40, to name just a few available.\r<br>\r<br>If you are interested then I have other educational videos on Carburetors. Please take a look at some of the links below.
