      Hello Akbar

      Thank you for visiting my website and for the comment, this topic is one of many that I did
      as my website is orientated to helping visitors increase their basic knowledge of cars and it’s various components,
      I am a 30+ years mechanic and I am still very much physically active in my trade.

      I try not to go into much detail, for now, as I feel I do not want to overload my audience with
      too much information and make the topic boring.
      As my website grows I will go into more detail on subjects in my articles, I also try to write in a natural easy
      to read and understand manner, which in my opinion, appeals to a wider range of audience.
      I also try to post 1 new article per week to keep my website interesting and current.

      Once again Akbar thank you for the visit and comment, I wish you well ahead.

      Gary
