It’s a must-have…

“I’ve always done oil changes on our 2006 Silverado 6.6 Duramax on schedule, often around the 5,000 mile mark. I’m a bit of a stickler for conscientious maintenance with it, and believed that regular oil changes using brand name synthetic oil would be sufficient to keep the engine clean. Turns out I was quite mistaken. I heard about Flushing Oil Concentrate from my father who uses it on a number of his vehicles, and thought I’d get some and give the Duramax a flush, not really expecting much. When I did the flush, I was astounded at the amount of sludge and muck that came out with the old oil! I had no idea it could be as contaminated as that! I’m converted! Flushing Oil Concentrate will continue to be an integral part of my oil changes in the future, it’s a must-have…”
