One thing's certain when motorists switch to AMSOIL synthetic motor oil; their engines are being treated to the finest lubrication money can buy. And while some engines appear to take the change in stride and continue operating the same as ever, others seem transformed. What may new AMSOIL users experience?
Oil pressure moderates: At idle, a slight oil pressure drop indicates the new oil flows more freely than the old oil did and that's beneficial to the engine. High oil pressure at idle indicates the oil pump must work hard to push the oil through the engine, which is stressful for the pump. Hard-to-pump oil may also leave some components underlubricated and unprotected.
If they keep an eye on their oil pressure, new AMSOIL users will find it's steady as she goes - at the new, better pressure.
Higher Engine RPMs: Because AMSOIL synthetic motor oil generates less intrafluid friction than conventional oils do and do a better job during boundary lubrication conditions, engine bearings rotate more easily with AMSOIL in the engine. You get more bang for your fuel buck. For a given amount of energy, a bearing that moves easily rotates faster than one that doesn't move freely.
Increased Fuel Efficiency: Less intrafluid friction and smoother boundary lubrication translates into fuel savings as less energy is used to overcome the friction required to move the vehicle a given distance.
More Power: Yet another side to lower intrafluid friction and better boundary lubrication. The power the engine used to overcome both with conventional oil now goes to moving the vehicle. Many users report their shift-points actually decreases due to the "extra" power their engines find with AMSOIL.
"Spring" cleaning: Synthetic oils clean as they go, removing sludge and deposits left by the previous oil. if AMSOIL synthetic motor oil is installed in a particularly fouled engine without an AMSOIL Engine Flush pretreatment, sludge and debris, freed by the cleaning action of AMSOIL, ends up in the oil filter. Motorists should change their filters frequently until the cleaning process ends. Oil consumption will increase if full-filters are not changed. Once completed, the vehicle's oil consumption rate will return to normal or even to a rate lower than its customary rate.
Of course, AMSOIL synthetic motor oils actually help engines achieve extremely low oil consumption rates, due to the oils extremely low volatility.
Easier Cold Starting: Less prone to low temperature gelling, AMSOIL synthetic motor oils allow engines to turn over more easily in colder temperatures than conventional oils do. In fact, most AMSOIL users find they no longer need block heaters.
Lower Operating Temperature: Oil sump temperatures may run as much as 20º F coller with AMSOIL than they do with conventional oils. Friction generates heat, and since AMSOIL synthetic motor oils generate less intrafluid friction than other oils do, they also generate less heat.
Additionally, AMSOIL synthetic motor oils are better heat transfer agents than conventional oils are, so the engine's total heat "bill" adds up to less with synthetics. Flexible synthetic lubricant molecules allow heat to swirl away from hot surfaces and into the midst of the oil stream. (It's called "turbulent flow.") Rigid conventional oil molecules move heat along the hot surface. The surface of the oil film gets overburdened with heat while the core of the oil stream gets a free ride. (It's called "laminar flow.") Plus, the carbon deposits formed as conventional oils break down coat and insulate hot surfaces.
