Muscle MT-10® Drops Harley Oil Temperature

Submitted by:  Barry Parker, Cullman, Alabama.

Mr. Parker has been using Muscle MT-10® for more than 20 years. “I use it in my work van (320k + miles) in the motor, transmission, rear-end and power steering pump.” And he says all his wheel bearings are packed with Muscle Power-Lift PL-10™ Grease. “It's [MT-10®] in my pickup, Corvette, motorcycles, tractor, mowers, tiller.”

Mr. Parker said he bought a 2005 Harley Davidson in 2012, and “When August rolled around, I started hearing engine noise when the oil temperature reached 240 degrees or so.”  He explained that Harleys are air cooled and notorious for heat issues.  “A Harley mechanic told me that ‘When straddling that many moving parts I should be concerned if I didn't hear engine noise.’" After a lot of research, Mr. Parker found this was a common issue. He checked everything… even the cam tensioners for excessive wear, which were within tolerance.

Although the Harley was not due for service, he decided to change the oil in the crankcase, primary and transmission, adding Muscle MT-10®. He reports, “Within 100 miles the noise was gone, and the oil temperature had dropped 40 degrees. 40 DEGREES! Less friction means less heat! This is a great product!”

“If it's made of metal and it moves and makes contact with other metal parts I use MT10 on it!  Thanks Muscle Products.”  Thank YOU Mr. Parker!
