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.

HitchBOT, the Hitchhiking Robot, Dismembered in Philadelphia

By Matthew Blockus on Aug 03 2015

Two weeks ago today, Industrial Outpost posted a story about a hitchBOT, a small robot that's the product of a social experiment by two Canadian researchers to get it from Boston to San Francisco with only the help of friendly passerby. In the time since our initial post, hitchBOT has travelled from Boston down the east coast to New York, and from there to Philadelphia.

However, the City of Brotherly Love does not have love for robots.

HitchBOT was last seen in working condition on August 1, but by the following morning, he was no more. "Unfortunately, hitchBOT was vandalized overnight in Philadelphia; sometimes bad things happen to good robots," said the hitchBOT team in a statement on their website. Also stated is that there will be no attempt to pursue or press charges against those who damaged hitchBOT. "We know that many of hitchBOT's fans will be disappointed, but we want them to be assured that this great experiment is not over. For now we will focus on the question 'what can be learned from this?' and explore future adventures for robots and humans," they said.

The researchers plan to retry the experiment in 2016, with Philadelphia as the new starting point.
