This is NOT a Redline vs. Amsoil post, just a post whereby Redline confirms Amsoil's claims of Extended Drain.
Redline FINALLY confirms Synthetic Oil Extended Drains.
Amsoil has confirmed and marketed this for 30 years.
--------------------------------------------------
Redline's new information per their website:
"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 5,000 to 7,500 miles in order to assure filter durability is not a problem." ... etc., etc.
--------------------------------------------------
Amsoil comments regarding Extended Drains (in my words):
Amsoil has been in the oil industry for 30 years. Due to Amsoil's superior synthetic composition and advanced performance additives, AMSOIL performs much longer than do conventional petroleum and other synthetic motor oils. No other major oil manufacturer matches AMSOIL's 25,000-mile or one-year drain interval recommendations (whichever comes FIRST, changing the filter every six months).
However, the 25,000 mile /1 year that is on the back of the bottle IS NOT an absolute! One must realize that is for non-severe service (highway miles where you have stable operating conditions) and that the indicated drain interval also has a time period of 1 year maximum as well.
Under a combination of city and highway circumstances, AMSOIL recommends up to 2 or 3 times longer, it means up to 2 or 3 times the equipment manufacturer's recommendation (If your owners manual states 3k miles , then you can change at 9k, and if your owners manual states 5k then 12-15k changes would be alright based on driving habits ... the harder you drive, the sooner the change). Proper filtration is also very important. AMSOIL SDF Oil Filters must be changed at least every 6 months regardless of miles driven.
Notice: Modifications to engine will change service intervals.
Notice: More frequent service may be required under severe service operating conditions.
Notice: For drain interval beyond 3x manufacturers recommendations (especially the 25k change) --- Regular oil analysis is recommended for establishing drain intervals.
AMSOIL --- 30 years of manufacturing oil and mountains of data and tests make these clains possible.
