Mechanic recommendations in Mandurah WA

[Winter XR8]

Hi guys, I moved to Mandurah a couple of months ago. Im after some recommendations for good mechanic shops in the area. I just need to get a log book service done but I have my own oil and filter to use. I went to one shop and they refused to do it. He said they will only use their oil and filter. I had the same brand filter they use but he said they cant warranty it. The car is 05 and has no warranty anyway. Can anyone recommend a mechanic place they use in the area?
