James Ebert uses Lucas Heavy Duty Oil Stabilizer for 1996 Chevy Truck
My 1996 Chevy Truck 350 Vortec Engine with 51,000 miles hasd one or more valve lifters making noise. I took my truck to the Chevy dealer here in Dewitt Michigan. The service manager let me talk to the head mechanic about my noise problem. He told me to go to the local auto supply store and purchase a quart of Lucas Oil Stabilizer.
Well, the results were fantastic. After about 40 miles of driving I felt like I got a new truck. I can't believe how quiet my engine runs now.
When a GM dealer recommends your product over theirs that really says something.
