DRAIN INTERVALS
Red Line stands alone in the ability to provide
extended drain intervals and lower friction and
wear. Red Line Synthetic oils have been shown to
last 25,000 miles in field tests; however we recommend
shorter drain intervals in order to provide a
margin of safety with the oil. We recommend draining
the oil between 12,000 and 18,000 miles
depending on the type of service and the degree of
blow-by gases contaminating the oil. High-speed
freeway driving is easy on the oil due to its excellent
thermal stability. If the engine is worn and if
considerable stop-and-go driving is involved,
10,000-12,000 mile drains are suggested. A good
rule of thumb to follow is to change the oil at least
once a year regardless the mileage. Manufacturers
warranty requirements should be followed while
under warranty. Filters can be changed every
7,500 to 10,000 miles in order to assure filter
durability is not a problem. |
