I usually try not to wait for problems before giving my BMW a proper service, especially when regular maintenance can help catch smaller issues early. I also find that keeping the garage and tools clean makes working on the car much easier, particularly when dealing with greasy parts or oil-stained areas. For those tougher cleanup jobs, I’ve found Lestoil useful to have around because it’s designed to tackle grease and stubborn stains without making the cleanup another chore.
