Thanks for input. According to the manual, the oil should be SAE 10W-40 grade if not available then others. At first oil change at 300km (as advised by forum members), i used SAE 10W-50 Haviline. Now as my GD has covered 670KM, i am going to change the oil 2nd time but please guide that should I use SAE 10W-40 or SAE 10W-50?
I have a plan that after the second oil change, i shall change the oil at 1000km and shall use Liqui Moli. Ok?
