yup...your right bro...this engine oil is quite new in the market,started at the year of 1997,and they are using Japan n air-space technology....the most travelling mileage engine oil in the market is only 20,000km...this one last for 100,000km...just imagine after 1 change of this engine oil....u dont need to go workshop til 100,000km...tat means about 3 years to 4 years time...but u need to go change ur oil filter after 50,000km...only oil filter....this is becoz this engine oil can break the big particles in ur engine oil...tats why u dont need to change oil filter every 5,000 or 10,000km....this is becoz long-term usage of oil filter--Regular engine oil is liquid,the gathering micro particles smaller than 1/100 micron are freely moving. As these micro particles mixed with the oxide, the carbon, or the sulfuric acid, they will grow into much bigger particles. As the particles become bigger, each particle increases in viscosity. Therefore, the particles cannot go through the oil filter, causing the filter to lose its effect. Thus, the regular engine oil is not useful. Using TOHO in regular engine oil controls the particles from growing, making it easier to go through the filter and maintaining its high performance...just some facts about this engine oil...hahahaha...sorry man trying to promote...but i'm using it myself....
