Can I switch between synthetic and conventional oil?

Yes, it’s possible to switch between them, although it’s best to follow your vehicle’s manufacturer recommendations. If your car is older, consult a mechanic before making a switch.

Is synthetic oil worth the extra cost?

In most cases, yes—especially if you want longer intervals between changes and better protection. For frequent drivers or those in extreme climates, the investment often pays off.

How often should I change synthetic oil?

Many full synthetic oils are rated for up to 10,000 miles between changes, but always check your vehicle’s maintenance guide for specifics.

The New and Improved Petroleum Service Company

We Are Industrial Pioneers

Petroleum Service Company is —the pioneer of —online petroleum sales. But what does that mean, exactly?

If you break it down, you can start with the obvious: we sell petroleum online. But not just any old petroleum. The good stuff. No matter your individual petroleum needs, we are sure to have both the product and the necessary information to provide you along every step of the way. We —have completely revolutionized the way you (yes, you!) can purchase lubricants. Seriously, where else are you going to find the biggest selection of industrial & manufacturing lubricants, automotive engine oil, aircraft lubricants, and rust-preventative coatings all under one roof (err--site)?

And —that —is why we are pioneers: because no one else is quite like us. —

Being pioneers can be a lot of work. At Petroleum Service Company, we are always learning, always growing, and always changing; and sometimes you won't know if there's a better way to do something until you try.

We love the petroleum industry, we love what we do, and we want to share our passion by placing customer service at the forefront of everything we do. Besides our commitment to education our customers, we believe in necessary change, which is why we value customer feedback and reviews--we —want —to change and grow and improve our company as a whole.

You asked--and we listened

We are proud to announce that thanks to our valued customers, Petroleum Service Company has gotten a new and improved look with, more importantly, some enhanced featured to provide an ever better customer service experience.
