I'm working for a truck manufacturer and I have to analyse what our customers do with their vehicles (for example, how many kilometres do they usually drive per day, or how much fuel do they use?).
I'm not a native English-speaker and I'm not sure if I should say I'm studying "customer usage" or "customer use".
I've read many pages explaining the difference between both words, and I think "usage" is the right word, but I would like to be sure.
Thank you.
