  1. but automiraj at dematagoda recommended 5W – 30 oil for the hybrids. So its bit complicated who s right and who is wrong?


    1. Dear Kasun,

      No need to make the things complicated :).

      I have asked you to follow manufacturers’ recommendations. And also i have provide you the thechnical points of doing such.

      If somebody / organization asked you to deviate from manufacturers’ recommendations and do something else, Please ask “WHY?” from them. If they give a reasonable answer, please post it here and we can discuss about that.

      Anyway, the ultimate choice is yours.

      Thank You


  2. Hi Yasith , I have a Honda Fit GP-5 which has done 25000km.
    I’ve done 3 services since I bought it. For all of them they used Toyota 5W-30 motor oil.
    Is it wise for me now to change it to 0W-20 motor oil as recommended.


  3. Hello. Your website has helped me a lot to drive my car efficiently.
    Please tell me after how many kilometers should i do a service maintenance?
    I live in mauritius which is a tropical country. Which oil should i use?
