Top 5 Best Synthetic Motor Oil Reviews 2016 Best car oil brand best oil brand
Synthetic motor oils are becoming more popular now, most people know that the synthetic oil outperforms conventional oil.
There are a few years, there were only a handful of synthetic motor oils available but now there are more than a dozen that most DIY mechanics can choose Once you've decided that a synthetic oil is the best choice for your car, the obvious question is, Which one is the best.
Each TV spot for synthetic motor oil says theirs is the best most of the time, however, they offer vague reasons why they often don t offer any real evidence at all, based on soft slogans such as Nothing surpasses Mobile 1 or is liguid engineer.
To get a true gauge which one is the best, you really need to look at the actual scientific tests on all oils and not just a test, but several tests that test the various important functions of motor oil must provide that s what we offer here on this page Search all the test results and then judge for yourself.
The standardized test following the ASTM industry were performed on ten different synthetic oils in February 2013 All engine oils were obtained in November and December 2012 tests were carried out by a third party independent laboratory oils were coded to eliminate prejudice, meaning that the technicians did not know what the oils.
Thermo-oxidation engine oil simulation test ASTM D 6335.
Here oil 5W-30 synthetic motor that was tested.
Castrol Edge with Titanium Fluid Strength Technology.
The most important job of an engine oil to prevent wear of your metal engine parts that constantly rub together.
Three bearings stationary balls are immersed in oil in a triangle configuration, with a fourth ball bearing sits on top of them the upper ball is spun over the lower three balls while a large load is applied after a defined period of time, the test is stopped and the wear scar on the three balls is measured and average.
Over the wear scar, the better the protection against wear.
AMSOIL Signature Series has always excelled in this test, and these results are no exception No other synthetic oil protects against wear better than AMSOIL The first 4 oils were all wearing scars below 0 40 mm Note that Mobil 1 demonstrated the greatest wear scar far.
Total basic TBN is the measure of reserve alkalinity of the engine oil, which controls the acids formed during combustion TBN can also be used as a measure of an oil degradation in service motor oil with a high TBN and demonstrate good TBN retention are known to effectively reduce the corrosive effects of acid over time.
AMSOIL Signature Series has the highest TBN, two points higher than the next competitor This is why AMSOIL Signature Series excels in protection over extended drain periods.
Cold start simulation test determines the apparent viscosity of lubricants at low temperatures and high shear rates viscosity lubricants under these conditions is directly related to the engine at low starting temperature The test was carried out the results of -30ºC are reported in centipoise cP, with lower values reflecting cold starts easier and reduces fatigue of the battery in response to the NS API and ILSAC GF-5 specifications of the lubricating oil, a viscosity of engine cold start oil†should not exceed 6600 cps.
There was a big difference between the viscosities measured AMSOIL Signature Series introduced the lower cold-start viscosity.
Motor oils can form deposits when exposed to increased heat, which reduces efficiency and contribute to poor overall performance ASTM, Test Method for TEOST “is designed to predict the deposit high temperature forming tendencies of engine oil This test method can be used in oil samples screen or as a quality assurance tool ”.
Given the number of vehicles now equipped with direct fuel injection, turbochargers and other performance enhancement technologies that increase heat, deposit control has become increasingly important to meet API SN Resource Conservation and ILSAC GF-5 specifications of the engine oil, 5W-30 motor oil should limit the formation of total deposition of 30 mg or less.
The results show a series of performance differences between Castrol Edge oils only with Titanium Fluid Strength Technology and AMSOIL Signature Series Synthetic Motor Oil Total weight of deposit limited to 5 mg or less.
The volatility test determines NOACK evaporation loss of the high-temperature lubricants Service ASTM, “Evaporation can contribute to oil consumption in an engine and may lead to a change in properties of an oil ”1 As the test TEOST, low values in the Noack volatility test are particularly advantageous in modern-hot engines.
In the NOACK test, a candidate oil is exposed to heat and the circulating air After 60 minutes, the volume of remaining oil is weighed and compared to the initial weight, with the difference reported that the percentage of weight loss results should be limited to 15 percent or less to meet API SN and ILSAC GF-5 specification.
Although all oils were below the SN API and ILSAC GF-5 upper limit, the results indicate differences in volatility Würth Half limited oils weight percentage lost of volatility less than 10 percent, with AMSOIL Signature Series synthetic motor oil has the third best result.
AMSOIL Signature Series the fastest in 3 of 5 trials, and performed well in both No other synthetic motor oils has shown such good remaining results Some work well in one or two tests, but not well in other .
, Ask yourself what other motor oil brands also publishes so many tests of their product over their competitors more just spend lots of money on expensive television commercials and catchy slogans for 40 years, AMSOIL has produced best synthetic motor oil on the planet.
