A new synthetic grease from Lucas Oil originally targeted high-pressure points in valvetrains but has since found additional applications throughout the race vehicle. Called Extreme Pressure Valvetrain Synthetic grease, the new formula features a synthetic base that is heavily fortified with Molybdenum and zinc dialkyl dithiophosphate (ZDDP). 

“The need originally came for pushrod ends, rocker arms and other valvetrain applications like flat-tappet camshafts,” explains Tom Bogner of Lucas Oil. “Then, working with Lucas Off-Road and NASCAR teams we saw expanded applications where you have a lot of temperature, like axle splines or CV joints.”

The Lucas Oil synthetic grease is effective at high-temperature, high-pressure points, such as pushrod tips and flat-tappet cam lobes.

The grease is applied during assembly and is tacky enough to adhere to the parts long enough to provide protection until the designated lubricant (engine oil, gear oil, etc) reaches the critical friction areas. These benefits are gained in engines or other applications that use either high- or low-viscosity oil.  

“It can also be used in cold-temperature applications, like a snowmobile, because of the synthetic base,” adds Bogner. 

Eventually the grease will dissipate into the oil. Tests have shown that the grease does not obstruct oil passages or collect in the filter. The synthetic grease is available in 1- and 4-ounce containers.
