Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

Why It's Smart to Treat Your Classic to Engine Oil Analysis

It’s not just “golden-clear = clean” and “dark-opaque = dirty.” Motor oil is a complex, highly-engineered fluid before it’s even poured out of the container. And after it has been sprayed, dripped and sloshed around in a running engine for a period of time, coming into contact with multiple materials and wearing surfaces, it holds the secrets of that engine’s overall health.

There’s real science behind determining what the chemical and physical composition that oil can tell us. To learn more about this, and share it with you, we’ve tagged along with an enthusiast owner as he explores a new-to-him old-car purchase.

Or your newer vehicle if the engine is expensive enough to warrant the money and it's not a run-of-the-mill vehicle operating under nominal conditions.

I wouldn't bother for a daily driver that's not being thrashed and trashed. I went 30,000 miles on my last oil change due to heavy usage and the numbers weren't too bad but I usually try to change it around 15,000 to 20,000 miles. The report below is for a Cummins ISB 6.7L diesel that we bought new in 2013 that really only sees highway miles. I'm about ready to do my fifth oil change on this unit.

Not sure how well the text will display in this report.

I wonder, would an engine oil analysis before buying a used vehicle be a good idea?

$25 for some piece of mind.

Seller might take offense. Although the history is probably more important than a single snapshot.

I like the idea of offending a used car dealer.

Wear a plaid suit with wide lapels and wingtip shoes and ask for a job selling cars.
