Todays engine oil is far different than what you could buy only 10 years ago
This subject is always controversial & you may disagree with the research that i have done
before you read this, remember that if your vehicle is still under warranty, you may want to comply with your dealers recommended lubrication standards for mileage & duration (length of time)
every up to date article that i have read about the first oil change, reads that the first oil change should be done at the end of the break in period to clean out the metals that were not fully flushed out
in the machining process. The break in period on todays engines is 1000 km or 621.4 miles
The synthetics offer the only truly significant differences, due to their superior high temperature oxidation resistance, high film strength, very low tendency to form deposits, stable viscosity base, and low temperature flow characteristics. Synthetics are superior lubricants compared to traditional petroleum oils. You will have to decide if their high cost is justified in your application.
The extended oil drain intervals given by the vehicle manufacturers(typically 7500 miles) and synthetic oil companies(up to 25,000 miles) are for what is called normal service. Normal service is defined as the engine at normal operating temperature, at highway speeds, and in a dust free environment. Stop and go, city driving, trips of less than 10 miles, or exterme heat or cold puts the oil change interval into the severe service category, which is 3000 miles for most vehicles. Synthetics can be run two to three times the mileage of petroleum oils with no problems. They do not react to combustion and combustion by-products to the extent that the dead dinosaur juice does. The longer drain intervals possible help take the bite out of the higher cost of the synthetics. If your car or bike is still under warranty you will have to stick to the recommended drain intervals. These are set for petroleum oils and the manufacturers make no official allowance for the use of synthetics. Some oil companies, AMSOIL being an example, offer their own engine warranties. If the oils are used in compliance with the company's recommendations (including extended drain intervals) and a problem is caused by the engine oil, the company will pay for the repairs. Check with the company for specifics of any warranties offered.
Oil additives should not be used. The oil companies have gone to great lengths to develop an additive package that meets the vehicle's requirements. Some of these additives are synergistic, that is the effect of two additives together is greater than the effect of each acting separately. If you add anything to the oil you may upset this balance and prevent the oil from performing to specification
How to Read an Oil Bottle - What do those letters and numbers mean ...really?
Before you can read an oil bottle it helps to understand what all of the abbreviations stand for that you may see posted on a bottle of motor oil. This information will deal specifically with the typical bottle of motor oil you will find at your local auto parts store in the U.S.
SAE - Society of Automotive Engineers (http://www.sae.org
) - opens a new window
These guys set standards beyond those used in lubricants, but since this is the system most see on oil bottles dealing with viscosity, we'll list them first.
API - American Petroleum Institute (http://www.api.org/
) - opens a new window
Created around 1930 they have set the standards for oil quality and performance in the U.S. market. The API is comprised of the major oil companies. In other words, for the most part oil standards in the U.S. have been set by the oil companies until recently when the JASO and ILSAC came into the scene. ILSAC, JASO and the ACEA represent auto/truck manufacturers that set oil quality standards.
ILSAC - International Lubricant Standardization and Approval Committee (http://www.ilma.org/
ACEA - European Automobile Manufacturers Association (http://www.acea.be/about_us
JASO - Japanese Automobile Standards Organization (http://www.jsa.or.jp/default_english.asp
ASTM - American Society of Testing Materials (http://www.astm.org/
You may not see these guys on a bottle of motor oil, but they set standards worldwide for everything from bolts to electrical wiring. Their testing methods show up on all things including lubricants and filters.

More than 380 million gallons of used oil are recycled each year, according to the U.S. EPA, that’s more than 50 percent of all motor oil purchased annually.
Longer lasting oils can reduce the generation of used oil. However, once generated, used motor oil can be reused or recycled one of three ways: reconditioning, reprocessing/energy recovery or re-refining
Types of Oil Filters & oil filter ISO 4548-12 multi-pass test (newest standard)
•Oil filters that fall into the bad category are standard paper filters that have cardboard end caps. There have been problems reported where pieces of the paper or cardboard end up in unwanted places, such as the engine. Paper filters generally filter down to 40 microns
Advanced filters with oil filter elements made from paper, fiberglass and cellulose are effective down to 15 microns or less. Advanced filters also boast more surface area on their filter elements so they have more capacity to catch and hold debris in the oil. Some of the best and most effective oil filters utilize several filtering elements rolled into one.
No oil filter is 100 percent effective. When shopping for oil filters, read your oil filter label to determine what type of filter element is being used as well as the claimed percentage of effectiveness.
