The Dennis Road Automotive Basic Guide To Synthetic Oil

Posted March 9, 2025 3:32 AM

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.

Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.

Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.

Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.

Remember that marbles and pencils thing we were talking about? Well, that makes synthetic oil slipperier than conventional oil which means less friction in your engine. Your vehicle engine runs cooler, wears less and lasts longer. You also get a boost in power and maybe even an improvement in fuel economy.

Synthetic oil also lasts longer so you change it less often – which is great for the environment. With longer oil change intervals, you need an oil filter specifically built for the longer service life of synthetic oil. Talk with your friendly and knowledgeable Dennis Road Automotive service adviser about synthetic oil and synthetic blends – they might be just what you need to improve engine performance and extend the life of your vehicle.

What our clients are saying about us

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!

This shop was recommended to me when I was in need of a new mechanic after a botched Take 5 oil change that damaged my car, in addition to some other repairs. The staff was knowledgeable, thorough, and respectful. This is very important to me as a young woman who's had her fair share of poor treatment at auto shops. Jeramie especially, was informative and a great help through the process. The service was quick and reasonably priced. This will be my new go to mechanic :) quotes-image
