I have been using, by many years, a rudimentary way to check the condition of an engine by finger testing the deposits at the exhaust pipe. Taking a sample with a finger I find:
1.- If there are only grey traces (almost nothing on the finger), the engine has a good combustion and no oil burning.
2.- If the deposits paint my finger with a black and dry coating, the engine is using excess of fuel but no oil burning.
3.- If deposits are black and sticky, means oil burning.
I don't remember when started this way nor why but, would like to know if I am right or wrong.
Thanks
