Re-build your diesel. Put on a custom chip and that will make up for engine power loss.
NO! Don't attempt it. Don't run diesel in your gas engine and don't run gas in your diesel engine! It will cause your engine to run improperly with loss of power and lots of white or blue smoke. It will clog your engine and if you run it with the wrong fuel too long, will result in complete engine failure.
could be bad injectors
Most unlikely. Glow plugs simply preheat to allow the engine to turn over from cold.
Some diesel engines need to recycle to clean the air filters. Perhaps the 206 diesel engine is trying to recycle but is not completing the action. Also, some of the newer diesel engines need to go through a system check before starting the engine. Try turning on the key until the vehicle completes a system check (this could take about 30 seconds or more). Then, turn the key to start the engine.
1) It prevents damage to injectors and engine from debris in fuel. 2) Yes. This filter should be replaced at every other oil change to prevent power loss.
you do not say if your engine is gas or diesel. A gas engine has many sensors, any one of which could cause a problem, not to mention a borken catalitic converter, which could also have many causes. I have not found any reasons for a diesel to experience this problem. I think, that to correctly answer this question, you need to give a more detailed question.
What does reduce engine power means?
yes because load affect the efficiency of engine , it can be improved by increasing the supply of oil in governer.
Yes
Oil leakage and loss of compression and power loss.
My idle was running rough and slight loss of power (5 cylinder engine). The power loss is more noticeable on cars with less cylinders.
Shouldn't cause any damage! Adding 10% of petrol to diesel fuel was standard practice in sub-zero winters in the days before "winter-grade" diesel. It helps prevent "waxing" where the diesel fuel will turn into something like a soft candle wax at low temperatures. You may notice a slight loss of power until the petrol is out of the system. 4 litres in 40 litres of diesel should not damage your engine, the one thing it will do is give you MORE power as it works a little like a bottle of injector cleaner that you may add to a tank of diesel from time to time. It will cause higher temperature explosions in your combustion chambers and a little more power.
