For the labour of an oil change, I was quoted $25 for my car, and $65 for my motorcycle.
To change the oil and filter on my car, you have to reach in a super terrible spot prone to burning and cutting people who attempt it.
On my motorcycle? It's an enduro, I have a foot of clearance and can see the single bolt required from across the driveway, it also requires exactly 2 quarts.
I got quite quick at changing my bike oil, and continued to pay someone else to burn themselves on my car.
