Chevrolet Cruze Diesel engine oil

“…still amazed at how well it cleaned out the sludge and other muck…”

“Just thought I’d send you a picture of the dipstick approximately 700 miles after we did the engine
oil flush with the Flushing Oil Concentrate. The oil is still so clean I can hardly see it on the dipstick. I am still amazed at how well it cleaned out the sludge and other muck in my 2010 Chevrolet Cruze Diesel. I’d never thought diesel oil could be so clean. Amazing result. Many thanks.”
