Check these for your like would be easeir
Every week or weekend check your fluids of you car. When i say everything i mean anything that as a fliud indacator and dipstick. The best way to check is when the car has not been turned on becasue then this gives you the most accurate readings on the dipstick and the indicators.

What types of engines are out in this world ?
Car engines vary in design, but there are some components that are common to all engines and are used for engine classification. Engines can be classified in several ways such as the number of cylinders, the geometry of the block, or type of ignition system used.
Here are some explanations of the different types of classifications:
Fuel Consumption
The type of fuel burned by an engine provides a broad classification. There are two types of fuel which are generally used: gasoline and diesel oil. Gasoline car engines use spark ignition whereas diesel engines use compression ignition (no spark).
Engine Block GeometryThere are a few types of engine block geometry: V-type, inline, horizontally opposed, slant and W-type. Each refers to the layout of the cylinders as viewed from the front or back of the engine.
A V-type has two angled rows of cylinders, which form a "V." This formation is typically used in V6, V8, V10 and V12 configurations.
An inline engine arranges the cylinders vertically in a row, and is the most common configuration in a 3, 4, 5 or 6 cylinder car engine.
The horizontally opposed engine has the cylinders laid horizontally and opposite each other. This may also be called a Boxer engine, or a flat engine, and is a less common configuration.
A slant design is one row of angled cylinders forming a half "V."
A W-type configuration is composed of two V-type formations side by side.
Number of Cylinders
The number of cylinders is often used in combination with the engine block geometry (V6, slant four, inline four.) A car engine will have between 3 and 12 cylinders. The number of cylinders determines how powerful the engine is. An eight cylinder engine will be more powerful than a four cylinder engine. This is not always the case - depending on the technology in the engine. For example a turbo-charged four cylinder engine can produce more power than a standard six cylinder engine. The greater the number of cylinders in an engine will also indicate how smoothly the car will run as power strokes occur with greater frequency.
Ignition Type
Spark ignition and compression ignition are the two methods used for igniting fuel. Gasoline car engines use spark ignition whereas because diesel is a less combustible fuel, a method of compressing air to the point that a resulting rise in temperature causes ignition to occur with the addition of diesel is used.
Cooling System
Engines can be air-cooled or liquid-cooled. Liquid-cooled engines are the standard with most cars on the road. The early Volkswagen Beetle is an example of a car that is air-cooled, however most modern cars use are liquid-cooled due to strict exhaust emission standards. Liquid-cooled engines have internal channels called water jackets in the cylinder block and cylinder head, through which coolant circulates, removing heat.

Oil and Cold Starts
Oil weight, or viscosity, refers to how thick or thin the oil Is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high).
Oils meeting the SAE's low temperature requirements have a "W" after the viscosity rating (example: 10W), and oils that meet the high ratings have no letter (example SAE 30). An oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined by the length of time it takes to flow out of the hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high
rating.
Engines need oil that is thin enough for cold starts, and thick enough when the engine is hot. Since oil gets thinner when heated, and thicker when cooled, most of us use what are called multi-grade, or multi-viscosity oils. These oils meet SAE specifications for the low temperature requirements of a light oil and the high temperature requirements of a heavy oil. You will hear them referred to as multi-viscosity, all-season and all-weather oils.
When choosing oil, always follow the manufacturer's recommendation.

Advantages of Gasoline
The internal combustion engine burns fuel within the cylinders and converts the expanding force of the combustion or "explosion" into rotary force used to propel the vehicle. There are several types of internal combustion engines: two and four cycle reciprocating piston engines, gas turbines, free piston, and rotary combustion engines. The four cycle reciprocating engine has been refined to such a degree that it has almost complete dominance in the automotive field.
The engine is the heart of the automobile. It converts fuel into the energy that powers the automobile. To operate, it requires clean air for the fuel, water for cooling, electricity (which it generates) for igniting the fuel, and oil for lubrication. A battery and electric starter get it going.
Charles and Frank Duryea built the first American automobile in 1892. In the winter of 1895/96 they produced 13 Duryeas, which became the first horseless carriages regularly manufactured in the United States.
In 1900, at the first National Automobile Show in New York City, visitors overwhelmingly chose the electric car. Most people thought the gasoline engine would never last. One critic of the engine wrote that it was noisy, unreliable, and elephantine; that it vibrated so violently as to "loosen one's dentures." He went on to give the opinion that the gasoline motor would never be a factor in America's growing automobile industry. People were afraid that gasoline
engines would explode. Motorweek magazine referred to them as "explosives." At the show, a bucket brigade was standing by every time an "explosive," was cranked. However, just three years later, at the same show, the number of cars with four-stroke internal combustion gasoline engines had risen sharply.
Each "cylinder" of the typical car engine has a "piston" which moves back and forth within the cylinder (this is called "reciprocating"). Each piston is connected to the "crankshaft" by means of a link known as a "connecting rod".
