Is there a recommended procedure for switching to AMSOIL Synthetic Motor Oils?
AMSOIL Engine Flush: In a new engine with less than approximately 20,000 miles it is not imperative that AMSOIL Engine Flush be used. In an engine with more than 20,000-30,000 miles and beyond, that has been using petroleum oil the entire time, we highly recommend using the AMSOIL Engine Flush. What the engine flush will do is remove the petroleum oil sludge & varnish deposits from your engine and properly prepare your engine for AMSOIL Synthetic Motor Oil. You simply pour in one can for every 5-6 quarts of sump capacity (one can is sufficient for most all passenger cars & light trucks, with the exception of diesels), and let the engine idle for about 15 minutes then drain the oil and remove the filter while the oil is still warm. Do not drive the vehicle with the engine flush installed. If you have an extremely dirty or high mileage engine then we recommend installing a new engine oil filter prior to adding the flush so that you have full capacity of the filter available for capturing and holding the dirt particles that the flush removes. AMSOIL’s Engine Flush is a detergent based flush with some kerosene and other petroleum distillates that act as the carrier for the flushing and cleaning agents. The detergent used is a 2-butoxyethanol, glycol ether and is essentially a very concentrated form of the detergents used in motor oil.

There are no special requirements; however, in older vehicles or those with high mileage, it may be advisable to use AMSOIL Engine Flush first. This will ensure that the engine is clean and free of any accumulated contaminants which might have an effect on the service life of AMSOIL Motor Oils. In all cases, it is good judgement to install a new AMSOIL Absolute Efficiency Oil Filter (EaO) every time you change oil.
