Is Your Engine Craving Synthetic Motor Oil?

What tops your engine wish list? High performance? Maximum horsepower? Superior protection from extreme temperatures? Can you have it all? Absolutely! Considering the phenomenal power, speeds and temperatures today’s engines push, you’re asking a lot from your engine. It’s a fact: conventional motor oils just can’t handle the toughest engine conditions. What’s the answer? Synthetics!


Synthetic motor oil such as SYNTEC delivers the most superior engine performance you can get. It’s not a new concept. Synthetics actually have a rich history. Here’s a quick timeline to bring you up to speed.

1930’s – Primarily used by the military. Synthetic lubricants helped keep oil from freezing in army tanks during World War II winters.
1950’s – Jet engines appeared and synthetics really took off. Speeds, temperatures and altitudes increased. Synthetics met the challenge.
1970’s – Performance in race cars continued to show the benefits over conventional oils. Synthetic motor oil debuted in passenger cars.
1990’s – Castrol introduced SYNTEC 5W-50, followed by 10W-30. In the mid-90’s, SYNTEC Blend arrived.
Present – Synthetic lubricants are now used widely in: automotive, heavy-duty diesel, industrial, marine, aerospace and aviation.
As engines place more and more demands on motor oil, they will also demand synthetic oil for the highest standard of protection. To truly understand how special synthetic oils are, check out how they’re made…


Motor oil consists of two main ingredients. There’s Base Oil (85-90%) and Performance Additives (10-15%). Pay attention now because you never know when this might show up in a trivia question. The base oil comes from crude oil. Then, it’s chemically converted to perform consistently at the highest level scientifically possible.

Cool Oil Fact #1: Crude oil developed naturally from the remains of plants and animals millions of years ago.

Underground is where you’ll find crude oil. But don’t dig up your backyard yet. It’s deep down and pipelines and tankers must transfer it to refineries where they boil to separate it into components. Then, it’s further refined, purified and processed into base oil.

Cool Oil Fact #2: Base oils in synthetic motor oils are much higher in quality than in conventional oils.Today’s engines need to be workhorses.

To get maximum horsepower, base oils can’t do it alone. So performance additives are added to help fight off the formation of power-robbing deposits caused by fuel, water, acid, wear, metals and dirt build-up. When various additives are properly formulated with base oil, you get engine-ready motor oil.

Cool Oil Fact #3: Motor oil performance is determined by the composition, number and balance of the additives and how they interact with one another.

The refining techniques for conventional oils are much simpler than those used for synthetics. Synthetic oils contain higher levels of additives to provide superior protection. That’s why synthetic motor oil outperforms conventional. You’re about to learn why…


The motor oil you choose affects your car’s power and performance. How does synthetic compare to conventional? For starters, it:

  • Keeps engines cleaner longer
  • Can help engines “turn over” more easily
  • Offers superior protection in extreme driving conditions
  • Getting Hotter! Oils start to thin out and burn off at high temperatures. Compared to conventional oils, synthetic oils deliver superior volatility performance. For your car, that means lower oil burn-off, fewer tailpipe emissions and less need to top off oil.

Getting Colder! In extreme cold temperatures oils thicken, which can reduce engine flow. And engine flow is critical to engine protection. Synthetic motor oil is engineered to withstand extremely low temperatures by pumping through the engine quickly. That gives your engine damage prevention protection, reduces wear and keeps vital components well-lubricated.

SYNTEC: Synthetic Technology at its Finest
SYNTEC is the result of over 100 years of cutting-edge technical advancement and record-breaking performance. In tests that ran ordinary engines under extreme conditions, engines using SYNTEC performed better and lasted longer while those with conventional oil broke down sooner.

You love your engine. Give it SYNTEC and see how much it loves you.
