It is difficult to start the modern i30 cold car.

Three reasons, one is serious carbon deposition. Second, the friction of the lubrication system is large, and the running resistance of the engine is large. The third is to check whether the battery is fully charged. The first reason, you can go directly to the store to operate, but it is expensive and hurts the car. I suggest you get some additives to remove carbon deposits. 1 box box has a wonderful cleaning method, and the technology made by Americans can be tried. The second reason is that some antiwear agents can be used to enhance lubrication and reduce cold start resistance. I only use new and beautiful products, and an anti-wear treasure works well, not to mention my advertisement. This is just an honest answer. The third reason is to see if the battery leaks. If not, replace it. Hope to see you! , please adopt!
