I have a diesel car and filled up late summer. I did not use my car much and had some summer grade diesel fuel while using it in winter. I am now using winter grade diesel but the car runs fine in the warm afternoons. But when it is colder, it cuts out or hesitant. how to fix this? Do I need new fuel filter or with summer just around the corner, will it fix itself?

Hi there,
It might be best to take your vehicle to a diesel specialist to get checked as it may not be due to the fuel type, it may need new glow plugs or something further.
