Maintenance - First oil change

I took my Isis for a service in Eneos Car Center located in One Utama shopping complex. I was told by my friend who sold me the car to visit this place called Utama Tire in Damansara Heights. I knew the place, but I don't really want to go there if I was awake like 10 in the morning because although the shop was a corner unit, the place was extremely crowded.

At first, I was a bit skeptical because I hardly seen any Isis on the road near Petaling Jaya, so I was not sure whether the mechanic would know how to fix it. I didn't want to bring it back to Vision in Bangsar because they charged pretty high. Thankfully that everything turns out alright. They did a checkup on the oil filter for the Isis 1.8 1ZZ-FE engine, and their people told them to use the same oil filter for the Toyota Wish, which I've did some research that both Isis 1.8 & Wish 1.8 shared the same engine in Japan, but not sure about the Malaysia version of Wish. Well, if it works, then I don't really mind.

I took the RM 175 package that comes with 5W-50 synthetic engine oil (Eneos Pro Racing), oil filter, car battery checkup (of no use because my Isis is using maintenance free battery), and fill the tires with nitrogen gas. I bet it's a good price for such package, because I would expect to pay more than RM 200 for synthetic motor oil. The disappointment that I had was that I was told by my friend that synthetic engine oil normally could last for about 10,000 KM. It will be good for me because I travel a lot. But the sticker still written and asking me to come back after 5,000 KM, so I was really not satisfied with it, and asking one of the staff regarding this matter. The staff told me that they would recommend people to come back at 5,000 KM because if driving more than 5,000 KM, the engine oil would vaporized and become lesser. Well, I just accept it as the guy said.

Some interesting things about the description that I found, written in Japanese, under the hood of my Isis. I could read and understand some simple Japanese writing. Here's what it said:

1. Oil change - every 10,000 KM or every 3 months
2. Oil filter change - every 15,000 KM

Of course, the above is achievable only if I'm using the recommended grade of engine oil written with the information above.
