I agree. All things being equal, I wouldn't even bother with the synthetic or semi-synthetic HDEO, weather conditions permitting. I'd stick with a 10w-30 or 15w-40 HDEO over a few short OCIs. My cleaning regimen for my sludged Ford 300 before the rebuild was MaxLife semi-synthetic 5w-30 for winter, followed by Delvac Super 15w-40 for the summer, all with short OCIs. It worked extremely well. The rebuilder said you could eat off the oil pan, and has never seen an engine so clean, yet with so many things wrong with it.
