Different garge will have perference on different engine oil. I think they can buy a big amount of engine oil which could be cheaper than you to buy only one. 偈油格 should be included (only 30-50). If the garge saying that their 偈油 is good and no need to change 偈油格 everytime changing 偈油, don't be fooled by them. It is better.
You can even buy 偈油 by youself. Many many car shops like in Sam Shui Po will have 偈油. Then you can ask garge how much is needed if you provide the 偈油 by yourself.
Mobil No 1 can be brought at gas station, when you fill-in gas, you can just go into their shop and take a look on them. Teach you a thing, you can check out "API" value, "SL" or above is the most good engine oil already. 4L is usually enough for 2000cc or below car.
