My new Corolla GLi (1.3L) is now approaching its 5000 km first oil change mark. I was wondering which oil brand and grade I should go for?
I have always used Shell Helix in all my cars. I intend to stick to Shell Helix Ultra for the first oil change as well. However, expert opinion is needed.
Also can someone please explain the oil grades to me? Eg Shell Helix Ultra is 5W-40 grade. What does that mean?
Thank you and regards,
