I pulled a "car trailer" for years with 1,9 turbodiesel 100hp... going uphill was sometimes very slow, especially when I was pulling my old Peugeot J7 fully loaded on the trailer (more than 2T, the car is supposed to cope with 1T3 max). Got a fine for that once, never tried it again.
Anyway I'd like to replace my car, and was considering the new Quashqai, especially since the old 1,5 DCi is gone.
Regarding oil, you can sometimes have nice surprises in buying oil in bulk directly to the seller (I said sometimes!). For example the nearest Renault here is selling some C4 5w30 Igol oil for a decent price.
