Castrol's "Think With Your Dipstick" campaign, one of the more memorable commercials we can recall for a motor oil, is currently plying the airwaves. An enigmatic Scotsman ambushes schlubs who proclaim "all synthetic oils are the same," delivering a deadly whip across the legs and exhorting the men to "Think with your dipstick, Jimmy!"

There's also a behind-the-scenes video that shows highlights from the ad's production. Humorous spots are usually infused with whimsy amongst the crew, and these Castrol productions look like they had a heck of a lot of fun after the serious business of setting up silks and HMIs was done. Notably, Castrol itself brings this video to the world, tweeting about it on their Twitter feed. A deft little bit of new-age marketing savvy, this. Be sure to check out the behind-the-scenes video – along with the finished spot – after the jump.
