A soon-to-be released study by global research firm Frost & Sullivan predicts major change for the U.S. engine oil market for Class 4-8 trucks by 2018, driven heavily by the need to boost fuel efficiency ahead of new federal greenhouse gas (GHG) mandates for commercial trucks along with increased use of smaller engine blocks and hybrid propulsion systems.
Can synthetic oil actully bring savings over the cost of it? I mean thats what most always say its good but cost too much.
Synthetic diesel oil will boost the fuel economy, plus it will help reduce oil consumption and it alos has lower volatility (evaporation) than conventional motor oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Lower volatility means that the synthetic diesel oil retains its viscosity after high-temperature service for excellent fuel economy not to mention the protection that conventional oil cannot match.

Again what FleetOwner stated:
“Right now, one of the issues with low viscosity oils is that they do not apply well in warmer regions of North America,” Lau pointed out. “Yet [diesel] fuel costs across all of the U.S. and Canada are predicted to only keep rising, so fleets want the fuel saving advantage of a low viscosity fluid. Our fleet focused research indicates steadily rising interest in advanced engine oils which is already translating to rising aftermarket demand for synthetics and semi-synthetics. It is only a matter of time before we see these fluids in the factory-fill market.”

Well not all synthetics are so.The best synthetic oil for diesel engines is really down to one statement the proof is in the pudding.

600 K Mack Trucks ??? You bet this is worth the few minutes to watch

Wow thats some proof!

Are Synthetic Oils Better Than Conventional Oils? Can you really tell any difference in your cost and operation of your vehicle?

What is the big deal about synthetics anyway isn’t natural stuff the best?

Synthetic oils are more resistant to oxydation and acids, increasing service life. Some users have started monitoring the quality of of their oils as they are used so that they are only replaced when necessary.

A petroleum product’s “cloud point” is the temperature at which solids become visible in petroleum products. Synthetic oils have a lower cloud point than conventional oils making them suitable for use in severe cold.

Synthetic oils reduce friction more than conventional oils. This improves fuel economy and power while reducing part wear.

Synthetic oils are also more resistant to burning, lowering oil use and engine soot. Many high-performance and low emissions engines now require synthetic oil to ensure engine sensors stay clean.

Just a word from Atermarketnews.com says this about synthetic oils being better:

The key benefit of synthetic oils is chemistry that allows them to perform for extended periods of time,” said Chuck Kerrigan, director of marketing, for Purolator. “In order to take advantage of the extended life offered by synthetic oils, motorists need an oil filter that can capture and hold the tiny particulates that can accumulate over time.

- The cost factor of oil changes are more effective using synthetic.(depends on how many miles you are driving per day/month/year) Not to even mention the longevity of your cars motor. More on that in another article.

Amsoil is the leader in synthetic oils.

The Four-Ball Wear Test evaluates the protection provided by engine oil under conditions of pressure and sliding motion. The size of the scar left as a result of the test determines the amount of wear protection the lubricant provides. The smaller the wear scar, the better the protection. Tests show that AMSOIL 10W-30 Synthetic Motor Oil has better antiwear performance than all other oils tested. With AMSOIL Synthetic Motor Oil, engine life can be extended and major repairs are often reduced.

The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and startability. The lower a lubricant’s cold crank viscosity, the easier an engine will turn over in cold temperatures. The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.

Controls Acid Formation

Total Base Number (TBN) is the measurement of a lubricant’s reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil’s TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time.

The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and performance over extended drain intervals.

The Thin Film Oxygen Uptake Test (TFOUT) is used to evaluate engine oil’s ability to resist heat and oxygen breakdown when contaminated with oxidized/nitrated fuel, water, and soluble metals such as lead, copper, iron, manganese and silicon. This test is designed to mimic the operating conditions of a gasoline engine.

AMSOIL 10W-30 Synthetic Motor Oil has superior heat and oxidation resistance to control sludge deposits and extend oil life. Engines stay clean for maximum protection and oil changes are reduced, saving time and money.

The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions.

AMSOIL 10W-30 Synthetic Motor Oil resists high temperature volatilization (evaporation) better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
