Petroleum gun, varnish and harmful deposit form
Every engine suffers from gum and varnish problems. Gum and varnish form naturally in every engine as fuel degrades and becomes heavy and sticky. These harmful residues and deposits can restrict fuel and oil flow through the engine, which puts stress on engine parts and causes performance problems. Overtime, these problems build up and cause parts to wear out prematurely. Cleaning gum and varnish from your fuel and oil systems is the easiest way to prevent engine problems.
Below are seven common engine problems that millions of people deal with every day. Every problem listed can be avoided or minimised by using polytron in your fuel and oil regularly to clean your engine and prevent harmful residues and deposits.
Hard startingHard starting means that your engine no longer starts easily on the first turn of the key, or you need to pull a small engine start rope more than two or three times. From there it only gets worse. A healthy engine fires and starts right away.0
Common causes: Clogged fuel filter, dirty fuel injectors, dirty carburettor, failing ignition parts (coil, spark plugs and plug wires) and leaking fuel pressure regulator.
Idle is the rate an engine runs while in park or without pressing the gas pedal or throttle. Most car and truck engines idle steady at 600 to 1200RPM. You will know you have a rough idle when your engine feels shaky, sounds unsteady, or gives a sense of being out of rhythm.
A healthy engine idles smoothly and quietly.
Common causes: Dirty fuel injectors, dirty carburettor, bad spark plug or plug wire and vacuum/air leak.
A stall is when an engine dies out when it’s supposed to be running. Though the engine may start back up again, stalling usually means that the engine is not getting enough fuel or airflow. A healthy engine never stalls.
Common causes: Clogged fuel filter, dirty fuel injectors, dirty air filter, bad spark plugs or coil.
An engine with a hesitation problem will lag, stutter or stumble when you press down on the gas pedal or throttle. Hesitation can be any delayed power response when you need to accelerate.
Common causes: Clogged fuel filter, dirty fuel injectors, failing ignition parts (spark plugs or plug wires), vacuum/air leak, weak fuel pump and bad fuel
Loss of power
Loss of power describes an engine that still runs but does not work as hard as it should. Power loss is usually noticed when going up hills.
Common causes: Clogged fuel filter, dirty fuel injectors, dirty air filter, weak fuel pump and failing ignition parts (coil, spark plugs and plug wires).
Loss of MPG
Are you noticing a drop in fuel economy? Poor fuel mileage means your car or truck is not running as efficiently as it should.
Common causes: Dirty fuel injectors, low tyre pressure, dirty air filter, bad spark plugs or misfires, using the wrong motor oil, chamber deposits (pre-detonation, pings.
Fuel degrades when exposed to oxygen (which makes it unstable). Gasoline suffers from the evaporation of light ignition vapours necessary for healthy combustion. If your fuel is old or came from an unreliable source, it might be causing your engine to run poorly.
Common causes: Engines that sit too long (varnish), water contamination, contaminated gas station fuel, vented fuel tanks or storage containers that sit too long
Here’s a checklist of the most common parts and issues to inspect when figuring out an engine problem. You can use these keywords and problem descriptions as a starting point for talking to a parts store, a mechanic, or learning how to work on your vehicle yourself. Take advantage of this guide–it will help you avoid engine problems.
Fuel filter: Fuel filters should be replaced every year (diesel) or 2years (gas engines). Is your fuel filter clean and new?
Ignition coil, spark plugs, and plug wires. If your car or truck has over 100,000 miles, have you replaced any of your ignition parts? Dirty intake valves: Don’t let carbon deposits form on your intake valves. You don’t need to be an expert to clean your own intake valves. Fuel pump: A fuel pump can last over 200,000 miles. Checking fuses, voltage, or testing fuel pressure are low cost ways to keep tabs on your fuel pump. A clogged fuel filter will wear out a fuel pump prematurely.
Air filter: An air filter should last 15,000 to 30,000 miles. Is your air filter clean and new?
Gas cap tight? (free): Ever get a check engine light because you didn’t turn your gas cap tight? Don’t panic!(Everyone forgets)
Vacuum/air leaks: Lots of do-it-yourself methods on how to find a vacuum leak. Check out YouTube.
Low tyre pressure (free): If you notice a drop in MPG, check your tyre pressure first before you start looking into other causes.
Check engine light: Most auto workshops are happy to read your engine code for a fee.
Oil restrictions and oil burning. Cleaning away oil restrictions can be as easy as pouring a can of polytron into your oil crankcase every interval.
