Every manufacturer has to meet the minimum standards set forth by the ASTM and SAE. Do you want to have the minimum standards met, or do you want the maximum performance an oil can provide?   

90% of the cost of any motor oil is the additive package that goes into it.

Oil manufacturers will never have the same goal as you have to overcome wear and extend the life of your engine, and can never meet that goal given the way their incentives differ from yours. Oil companies add a minimum standard of additives to their products. BestLine is patented and proven to keep components clean, lubricated and cool to minimize mechanical failures, and we meet the highest standard of wear protection and extended engine life that more than pays for the extra cost of the patented BestLine additive advantage. And we can prove it.

Oil is the lifeblood of your engine. It reduces friction, lessens wear, provides lubrication, forms a seal between the pistons, rings and cylinder walls while helping to cool engine parts. Without the cleaning action of new oil with BestLine Engine Treatment, carbon and varnish buildup would be toxic to the engine. BestLine not only reduces wear by over 80% as proved in clinical studies and by our 52 Worldwide patents. 

 

About Engine Oil:

Each engine oil comes with a classification indicating its viscosity, which is its friction or resistance to flow. In a multi-grade oil, the first number indicates how the oil will flow when it is cold. The lower the number, the lighter the oil and the better it will perform at lower temperatures. The second number indicates the thickness of that same oil at high temperatures. For example, a 5W-30 oil will flow as a 5-weight oil at zero degrees F and as a 30-weight oil at 210 degrees F. 

What is Viscosity? 

During cold starting, only a small amount of oil is present in the upper parts of engines. To lessen the friction when upper engine parts, such as the valve train, pistons, overhead cam and cam bearings, scrub against each other, a lower viscosity allows the oil to reach the components more quickly. With BestLine you are assured that those parts are always protected with our patented micro-lubricants.  

 Why are low viscosity oils more popular and required now? 

Many vehicles today leave the factory with 0W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage. Many people think adding a viscosity improver ( thickener ) will help the engine. Thats not true, oil is not only a lubricant it is also a coolant. Oil lubricates and draws heat away from the small passage ways and orifices. If you thicken up the oil in todays tight tolerance motors you can do damage that is hidden from you for a while but it can cause premature wear and failure. 

Why Synthetic Oil? 

Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded long carbon chain lubricants, are also available. They can provide:

• Higher viscosity stability over a wider temperature range
• Reduced oil thickening
• Reduced wear and increased load-carrying ability.

• Synthetic oil lubricates better than traditional motor oil, and it stands up to high heat better without turning into gel or getting watery. Some blends of synthetic oil are designed to keep high-mileage vehicles rolling longer. Others are meant for high-performance engines. 
• Standard mineral oil becomes a super oil when BestLine is added to better protect your engine when you use a lower cost oil. 

Do I have to change my oil often if I don't drive much? 

Your owner’s manual should give you a recommended mileage interval and a recommended time interval for an oil change – for example, it might say “every 5,000 miles or every six months.” To help keep your car in tip-top shape, follow whichever oil change interval comes first – in your case, probably the time interval. Oil can go bad due to moisture build up in the crankcase so time not only mileage is a factor as to when to change the oil.
