The MOT exemption law for older vehicles was modified in 2018 by the UK Department for Transport. It used to be the case that only cars that were manufactured before 1960 were also free from the MOT test Reading for the current year. Now we have a more precise rule, which states that any car that is 40 years of age or older is exempt from licensing. However, for the owners to be allowed to use these vehicles on the roads, these vehicles need to be registered as Historic with the DVLA.. In conclusion, the fact that cars over forty years old do not need an MOT lessens restrictions for owners of classic cars.
Disadvantages of using incorrect Oil in Your car
Selecting the best motor oil for your vehicle is critical in maintaining your car in good condition and preventing expensive repairs in the future. However, many drivers are not very concerned with the type of oil they use and will purchase any which is cheapest and most easily available. When the wrong oil is used, there extends poor fuel economy, leaking of the oil, excessive heating and finally poor performance or conking off of the engine.
- Reduced Fuel Efficiency
The most obvious consequence of using the wrong oil is that the fuel economy is affected. Motor oil is not just thick- or thin; it is actually labelled according to the specific viscosity—or thickness—that is required for your car’s engine. When oil is too thick or too low in viscosity, it is unable to form a thin and uniform layer on these moving engine parts and adjust the amount of friction in the engine. Too much friction hinders free movement within the engine and requires more energy and fuel to perform a given task. Incorrect oils will cost you more cash than you actually have to spend on the gas.
- Increased Risk of Oil Leaks
Wrong motor oil can also compromise oil seals and gaskets faster than the recommended oil by the vehicle manufacturer. Due to the fact that motor oil fills in the clearances between immobile engine parts and other moving parts, the wrong thickness or additives may shrink, turn polish and even melt critical rubber or metal system seals. External oil leaks are experienced as the liquids find their way out of the failing seals all over the devices. Leakages in general are very messy and expensive, and much costly if they occur on the main crankshaft seal.
- Potential Engine Overheating
Last but not the least, the wrong oil might not only poorly lubricate all the engine parts but also cannot dissipate heat through friction. If the contact surfaces of what are sliding are not adequately lubricated, there is a tendency to develop high temperatures due to metal-to-metal contact. Even these types of temperatures when build up can lead to complete engine overheating and, in some cases, engine component melting or welding. Malfunctioning of one or more components of the automobile engine usually leads to engine overheating, mostly needing very costly service of overhauls or even replacements.
Getting the RIGHT motor oil is critical to prevent degradation of MPG; leakage; overheating and overheating, as well as fast wear and tear. Always ask from your car manufacturer or mechanic about the appropriate oil for use in the car. These few dollars spent at the beginning will bring huge benefits for increased efficiency and durability of the selected engine type.
Possible reasons as to why diesel fuel injection pumps fail.
- Contaminated Diesel Fuel
Wet, unstable diesel can contain water, oil, rust, and debris, which, if the fuel reaches the pump or injectors, will wreak havoc on any diesel engine. The contaminants then move through the fuel system and cause wear and tear as time goes on. A mechanic has to use some high pressure something in order to wash the fuel pump and the injectors by removing the bad fuel and other gunk.
- Low Fuel Levels
If you let your fuel tank run real low or even out, what happens is that instead of getting fuel being pumped through the injection system, air gets sucked in. Specifically, the air makes the fuel pump bearings succumb to wear out much earlier than expected. One major issue that could cause a fuel pump to fail is by letting your tank to go very low or even become empty. tHus its important to have a good car servicing Reading.
- Dirty Fuel Injectors
The injectors become dirty in due course and receive deposits of dirt and debris, hence requiring the above process. Dirt accumulation blocks fuel from reaching the engine and unblocks it when it ceases to accumulate. For the fuel pump not to fail, the injectors require to be cleaned or replaced now and then.
- Injector Timing Issues
When the triggers of the injectors are not coordinated, the injectors fail to fire at the correct time. This leads to a loss of power of the entire system. Late or early injector timing is also very destructive to an engine. A mechanic needs to adjust firing of injectors in order to correct problems resulting from timing failure of injection pumps.
