Just put Redex Fuel System Cleaner for petrol engines in a diesel car tank by mistake . Will this create any problem ?
Doubt it.May even make it run better.
Unless you put a lot in, I can't see it doing any harm. Diesel injector cleaner is similar to paraffin and that is clearly OK.
It won't hurt it. I used some petrol redex straight in a berlingo 1.9D after running issues. Filled the fuel filter with it. Certainly went better after.
