Answers to Havoline® engine oils

How do I know which Havoline® engine oil is the right one for my car?

Start by consulting your vehicle’s owner’s manual.

My owner’s manual says I need synthetic oil. Do I?

A lot of people are shocked to find that their new vehicle requires synthetic oil. That’s because the engines in newer vehicles are asked to deliver a complex balance of fuel economy, performance, low emissions, long engine life and — just to make it even more challenging — longer intervals between oil changes than years gone by.

Our recommendation? Follow the vehicle manufacturer’s recommendation. If they specify synthetic oil, it’s for a reason. And not doing so could void your vehicle’s warranty and shorten the
life of your engine. 

Is synthetic oil really better than conventional oil?

In a word, yes. It really is that simple. Synthetic oils protect better than the best conventional, mineral-based oils can, particularly at temperature extremes. You can find lots of explanations online about why synthetic oil molecules outperform conventional oil molecules, but the simple answer is: Yes. Synthetic oils protect better.

What is engine (or motor) oil?

Engine oil is essentially a mixture of base oil and additives used to lubricate engine parts, reduce friction, clean, cool, and protect the engine. Engine oil is comprised of two basic components—base oils and additives. These additives include dispersants, detergents, anti-wear additives, friction modifiers, antioxidants, anti-foam additives, and corrosion inhibitors, viscosity index improvers, pour point depressants, and more.

Modern synthetic engine oils are a complex mixtures of base oils and additive components designed to perform a variety of tasks: separating and lubricating moving parts, reducing engine wear, helping to prevent deposits from forming on internal engine components, removing and suspending dirt and contaminants in the oil until these contaminants can be removed at the next oil change, cooling engine parts, enhancing engine fuel economy, providing protection over a wide temperature range, operating hydraulics in variable valve timing, and even helping to protect the emissions system. In other words, modern synthetic engine oil does a lot more than just lubricate.

Why is it important to use engine oil in my engine?

By-products from combustion contaminate your engine oil and if the contaminants build up in the oil, they can settle and create sludge and deposits in the engine. If engine components and oil passages are dirty, vehicle performance, efficiency and fuel economy will suffer. Deposits can also trap heat inside the engine.

This is why it is important to use an engine oil like Caltex Havoline® Pro DS™ Fully Synthetic ECO 5 SAE 5W-30 or Havoline® ProDS Fully Synthetic LE SAE 5W-40 specially formulated to provide nonstop protection to keep today’s modern engines going. It even exceeds the industry’s newest and toughest protection standards, including GM’s dexos1™ Gen 2 or dexos2™ specification.
