Depends where which area you go. Labour cost is cheaper over there.
Let me give you an example: Non- conti cars. For regular service, EO and filter. Parts bring ownself, labour in SG oredi like $30-$50.
In JB, is RM30-RM50.
Cheapest regular servicing in SG: $33.30. EO change and OEM Filter and all the safety checks. This workshop still running. They use locally blended EO. Brand not popular. For COE ride, drivers may consider to use.
For newer rides, drivers may not consider.
PS: The key point here is the EO chosen. 5W30, TRD Motul EO with OEM filter, RM300. (Quoted to me last week) Let me know if any SG workshop can offer this price. After conversion is less than SGD$100. (Rate was 3.15, last week)
Also, please don't say, aiyo, the time and jam and the toll fee. Please exclude all these factors.
