The difference between semi-synthetic and mineral engine oil
Semi-synthetic oils (from wiki) Semi-synthetic oils (also called 'synthetic blends') are blends of mineral oil with no more than 30% synthetic oil. Designed to have many of the benefits of synthetic oil without matching the cost of pure synthetic oil. Motul introduced the first semi-synthetic motor oil in 1966.
Mineral oils are based on oil that comes from dear old Mother Earth which has been refined. Synthetic oils are entirely concocted by chemists wearing white lab coats in oil company laboratories. For more info, see the section on synthetics further down the page. The only other type is semi-synthetic, sometimes called premium, which is a blend of the two. It is safe to mix the different types, but it's wiser to switch completely to a new type rather than mixing. (From car bible)
Mineral oil is cheapest Standard motor oil is effective at protecting your engine. It’s also cheaper than semi-synthetic and synthetic oil. However, it must be changed more often, as it becomes dirty and thins out more quickly.
Semi-synthetic can be used more kilometer For mineral engine oil can be used for 5,000 km, while semi-sythetic can be used for 8,000 km.
Semi-synthetic engine oil is more light than mineral engine oil. Modern engines function well with lighter, thinner oils.
Many people love the warm sun. The sun's rays make us feel good, and in the short term, make us look good. But our love affair isn't a two way street: Exposure to sun causes many of the wrinkles and age spots on our faces and is the number one cause of skin cancer.
In fact, sun exposure causes many of the skin changes that we think of as a normal part of aging. Over time, the sun's ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place. The skin also bruises and tears more easily -- taking longer to heal. So while sun damage to the skin may not be apparent when you're young, it will definitely show later in life.
How Does the Sun Change Skin?
Exposure to the sun causes:
Pre-cancerous (actinic keratosis) and cancerous (basal cell carcinoma, squamous cell carcinoma, and melanoma) skin lesions Benign tumors Fine and coarse wrinkles Freckles Discolored areas of the skin, called mottled pigmentation A yellow discoloration of the skin The dilation of small blood vessels under the skin How Can I Protect Skin From the Sun? Nothing can completely undo sun damage, although the skin can sometimes repair itself. So, it's never too late to begin protecting yourself from the sun. Follow these tips to help prevent sun-related skin problems:
Apply sunscreen with a sun protection factor (SPF) of 30 or greater at least 30 minutes before sun exposure and then every few hours thereafter Select cosmetic products and contact lenses that offer UV protection Wear sunglasses with total UV protection Wear wide-brimmed hats, long sleeved shirts, and pants Avoid direct sun exposure as much as possible during peak UV radiation hours between 10:00 a.m. and 3:00 p.m. Perform skin self-exams regularly to become familiar with existing growths and to notice any changes or new growths Eighty percent of a person's lifetime sun exposure is acquired before age 18. As a parent, be a good role model and foster skin cancer prevention habits in your child Avoid tanning beds
1.Checking Fluid Levels Check the engine oil level (engine off) the engine oil level dip stick is usually indicated by a yellow handle. There are two level indicator marks, upper level and lower level. The distance in between these marks represent a quart, if the oil is in between the marks the level is ok. If the oil level is below the lower level mark or not on the dip stick at all engine oil must be added until between the inductor lines.
2.Checking Tire Wear Condition Car tires are made out of flexible rubber which is incorporated with wire and fabric. The tires of an automobile support the braking, load, traction, and steering. Tires also absorb shock caused by bumps in the road and help provide a smooth ride to the passengers. Tires need to maintained at a prescribed air pressure and rotated at scheduled intervals. Most vehicle tire pressure recommendations are located on a sticker in the driver's door jam or on the side wall of the tire.
3.Checking Engine Coolant Hoses Engine coolant is used to transfer heat from the engine to the radiator, if a coolant leak is present the engine will eventually overheat. Inspect the engine coolant level in the coolant reservoir tank, coolant level should be between the hot and cold marks. Always check the coolant level when the engine is cold, preferably over night. If the coolant level is not between the reservoir marks the cooling system may have a leak.
4.Checking Horn, Headlight and External Lighting Systems The lights in and around your vehicle are not only a convenience they are a safety precaution. All lights on your vehicle should be working at all times, if fact it's against the law for any exterior lights on your car not to be working. If it was designed by the manufacturer to work on your vehicle it must work at all times. Make it a regular check for your vehicle to assure the proper operation for your lights.
5.Replace Wiper Blades Have a new wiper blades to ensure proper windshield vision and control of the car.
Watermelon is thought to have originated in southern Africa, where it is found growing wild, because it reaches maximum genetic diversity there, resulting in sweet, bland and bitter forms. Some foods are fun to eat, and watermelon is definitely one of them.
Watermelons are an excellent source of several vitamins: vitamin A, which helps maintain eye health and is an antioxidant; vitamin C, which helps strengthen immunity, heal wounds, prevent cell damage, promote healthy teeth and gums; and vitamin B6, which helps brain function and helps convert protein to energy.
Tomatoes have been highly touted as a great source for lycopene, a powerful antioxidant that helps fight heart disease and several types of cancer — prostate cancer in particular. Watermelon, however, has the highest concentrations of lycopene of any fresh fruit or vegetable.
It is a great source of potassium, which helps muscle and nerve function, helps maintain the body’s proper electrolyte and acid-base balance, and helps lower the risk of high blood pressure.
Watermelon also contains the amino acids citrulline and arginine, which can help maintain arteries, blood flow and overall cardiovascular function.
