“QUIETED THEM LIFTERS UP COMPLETELY!”
“My 2005 Yukon with the 5.3 had lifters start ticking at 225,000 miles. I tried different products to help quiet them down but no luck. I started using Sea Foam Motor Treatment before oil changes at 240,000 miles. Within 2 oil changes and 10,000 miles, Sea Foam quieted the lifters up completely!!”
