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.

Sun Safety Helpful Tips
(From Md Web)

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
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
