Synthetic VS. Conventional Motor Oil

When it comes to general maintenance for your car a proper oil change at regularly scheduled intervals is one of the most important things you can do as a vehicle owner. At Aamco of Keller we are commonly asked by our customers “what is the difference between synthetic oil and conventional motor oil”? Our goal is to be your locally owned and trusted Keller Auto & Transmission Repair Shop and to also help educate our customers on any questions they may have regarding their vehicle.

When it comes to motor oil, you have two popular options which include going with conventional motor oil or synthetic motor oil. The differences between the two begin at the molecular level and continue all the way up to how the oil is manufactured and processed. Conventional oil will cost less than the synthetic but will require more frequent oil changes. If you decide to go with the synthetic motor oil – depending on your driving habits it’s recommended that you change your oil every 5,000 to 7,500 miles for most vehicles.

What is Synthetic Motor Oil?

Synthetic oil is nonetheless oil, though it is somewhat man-made. Synthetic oil is made from a base oil, powder additives, and a carrier oil that enforces an even distribution of the additives.

Both synthetic oil and traditional motor oil are made from refining oil. Most synthetics begin with highly refined crude oil, pumped from deep underground. That is the same source as conventional oil. Other synthetic oils use artificially made compounds or a synthetic oil as a base oil. The primary difference between synthetic oil and traditional oil is at the level of refinement.

The base oil falls into one of several “oil grades” from mineral oils extracted from crude (Group I and II) to fully artificial, compound-based oils. All grades of oil are manufactured with additives that increase performance.

Refinement processes and ingredients also result in scientific control over molecular size and purity. That can lower friction, reduce engine sludge, and increase performance. Synthetic oil was first developed in 1929. With technology and access to resources, it has refined to accommodate jets, high-performance vehicles, and everyday consumer vehicles. The need for synthetic oils also comes from technological changes. High-performance vehicles and machinery—from jets that break the sound barrier to industrial plants—have to operate in extreme conditions and temperatures. Highly refined engine oil allows better temperature resistance.

Advantages to Synthetic Oil:

  • Uniform molecular size means less friction
  • Refinement and engineering reduce deposits
  • Additives boost protection and can clean engines
  • Better function in cold and extreme weather
  • Cleaner oil with fewer impurities

Full Synthetic vs. Synthetic Blend

Full synthetic oils are better understood as a grade of motor oil. Semi-refined–also called synthetic blend–oils are less refined than full synthetic oil. Semi-synthetic oil blends traditional oil with the more technologically advanced oils. You get the advantage of additives and more refinement. But, the impurities and inconsistent molecular size of conventional motor oil are still in the blend at lower degrees.

The benefit of synthetic blends is largely a cost-vs-benefit decision. Synthetic blends are cheaper than full synthetic motor oil but higher performance than conventional oil.

How often should you change Synthetic Oil in your car?

Synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends.  It’s important to remember to schedule regular oil change intervals. For conventional oil, twice a year is suggested as a safe way of keeping track. If you want to keep better track, every 7,500 miles is suggested for average cars. You should also change your oil filter every oil change. But, especially if using synthetic oil, every other oil change is sufficient if you don’t regularly push your car hard or endure extreme conditions.

Check your owner’s manual. Newer cars may be able to go 10,000 miles or only need an oil change once a year. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles.

Synthetic oil change intervals range 10,000-15,000 miles or once a year (whatever comes first). Extended performance synthetic motor oil is on the upper top of that range. That extra 5,000 miles may be worth the investment.

Synthetic Motor Oil vs. Conventional Motor Oil

Visually speaking you cannot tell the difference between new synthetic and conventional oil. There are two major differences, however. First, how they are made is a distinction. We’ve explained that synthetic oil is far more refined than conventional oil.

Second, the way they run in your car is worlds apart. Used motor oil shows a lot thicker and sludgy in conventional oil vs. synthetic oil, given the same amount of wear. Synthetic oil is by far better for performance. It protects the engine due to lower levels of friction. Additives help clean the engine of deposits. And, fewer impurities mean it burns cleaner, thickens far more slowly, and has fewer deposits to start.

“According to industry tests, synthetic oil engines perform 47% better than engines using conventional motor oil.” – AAA

Choosing the Best Motor Oil for your Vehicle

A full synthetic oil is the best oil option for any engine. Synthetic oil cuts down the hassles or oversights related to more frequent oil changes and deposits.

If synthetic oil is outside your maintenance budget, go with a blend or rotate between a full synthetic and non-full synthetic every other oil change. Changing car oil will not damage your vehicle. Keep a record to remember the mileage, next oil change date, and type of oil.

It’s always best to consult your owner manual to lookup your manufacturer’s recommendations on oil viscosity grade and their recommended oil specifications. If you have trouble locating this information feel free to give our team of experts mechanics at Aamco of Keller a call for their recommendations.
