Yeah Shariq you're right. I downloaded the Swift Manual online after quite an extensive search when I got the car back in Jan 2016 as the previous owner didn't have a Manual at all and since then I've pretty much headed back to the Manual I downed everytime there was something worthy of opening it up.
I don't know what the term OCI stands for so kindly let me know what that is.
That being said, I am satisfied with the 7500 Km oil change interval as is because I'm using good quality engine oil and those are pretty good at extending usage over 5000 kms.
One expert once told me that changing Shell, Liqui Moly , etc engine oil's before 10k should be made sacrilegious. That is how good they are.
I'm more than happy to send you a copy of the Manual I have so you can go through it if you want.
I've guided Suzuki Mechanics and made them fix issues at their workshops with the same Manual open on my tab and they didn't question it's integrity also so it didn't really make me think it was not the right one at all.
Maybe if you can send me yours if you have it saved online or something I can compare both.
Thanks for pointing this out.
