AMSOIL Engine Flush provides immediate engine sludge and debris removal.
AMSOIL synthetic motor oil will also clean deposits from your engine; it will just take longer.
People who are new to synthetic lubricants often ask what is the best way to switch from conventional to synthetic motor oil. There is still some confusion about changing to a different type of oil in vehicles, particularly older models that have accumulated many miles. A very small group of ill-informed individuals in garages, on street corners and on blogs still cling to old beliefs that synthetic motor oils will cause roller followers to “slip or skid,” or that switching to synthetic motor oil will cause issues in older engines. One common myth is that synthetics will cause older engines to leak oil.
“The main difference between flushing your engine and just a normal oil change to synthetics is the rate at which the built-up debris is removed from older engines.”
Fact Supercedes Fiction
These old ideas about synthetics causing engine problems are outdated and have been replaced by facts. The use of synthetic lubricants is growing rapidly because properly formulated synthetics offer benefits well beyond what conventional and synthetic blend products can provide. Many new passenger car and light truck vehicles come factory filled with synthetic lubricants — not just high-performance sports cars. Synthetic lubricants continue to be recognized more widely as the best choice for long-term care of expensive equipment. One Amsoil user was in a discussion regarding these and other myths surrounding synthetics. He recalled switching his and his wife’s vehicles over to AMSOIL synthetic motor oil. One vehicle had nearly 80,000 miles at the time, while the other had more than 115,000. For both, it was the first time running synthetics. He described his experience this way: “You know what happened? Nothing, except I noticed they both started easier in the winter – even when parked outside overnight. And now my wife isn’t wasting money at the quick lubes changing oil every 3,000 miles.”
Extreme Test Proves Amsoil Performance
In April 2013 AMSOIL published its Las Vegas Taxi Cab Field Study. This report details the results of installing Signature Series Synthetic Motor Oil and Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid into six taxis operating in the extreme desert conditions of Las Vegas. The cabs operated nearly continuously for the next year-and-a-half. After 100,000 miles a 2010 Dodge Charger was removed from service for teardown and analysis. Its engine components were examined, rated and found to be virtually sludge-free, with seals remaining in excellent condition. The test vehicle engines responded positively to and were protected by AMSOIL synthetic motor oil in the most demanding operating conditions, even while practicing extended drain intervals.
Two Methods of Making the Switch
For those of us looking at putting AMSOIL synthetic motor oil into a vehicle for the first time, there are a couple ways to approach the situation. You can jump right in and simply change the oil – draining the old oil, replacing the filter with an AMSOIL Ea® Oil Filter and pouring in fresh AMSOIL motor oil. Many people, like the customer previously mentioned, do this with excellent results.
Another option is to flush your engine prior to installing AMSOIL synthetic oil. This process more immediately removes sludge and debris accumulated over time. The main difference between flushing your engine and just a normal oil change to synthetics is the rate at which the built-up debris is removed from older engines. When customers change over to AMSOIL synthetic motor oil without flushing, accumulated debris is cleaned from the engine over subsequent oil changes. When customers use a flushing procedure, the cleanup is more immediate. Adding one bottle of AMSOIL Engine and Transmission Flush right before their next oil change will ensure the engine is clean and free of any accumulated contaminants that may be present. The steps are simple: Pour one bottle of Engine Flush into the oil fill port, idle the engine for 10-15 minutes, drain the oil and change the filter, then fill back up with the appropriate AMSOIL motor oil. AMSOIL Engine and Transmission Flush has a high-detergent chemistry formulated to remove built-up sludge and other deposits. The detergents work in a similar fashion as those already present in motor oil, just at a higher concentration. Therefore, AMSOIL Engine Flush cleans naturally, just like motor oil, but it does so more rapidly. The rapid clean-up does not break off large chunks that can cause an avalanche of debris to clog passages. Instead, it cleans at the molecular level, ensuring the deposits are dissolved and properly exit the engine with the oil when it is drained. This helps the new oil get off to a “clean start” and perform to its engineered capacity. By cleaning engines of deposits, it also improves operating efficiency, helps maximize fuel economy and reduces emissions.
The Choice is Yours
In the end, there is no mandatory procedure for switching to AMSOIL synthetic motor oil. It all depends on the situation, and most importantly, your own preference. Whether you drain and fill or flush, drain and fill, be confident that you’re putting the very best product into your engine.
