    Mobil Delvac 1 ESC 5W-40

    Posted by C. Alfred Santillo on Mar 10 2020

    II've owned and operated a farm in the snow bwlt of Central New York State. for over four decades. During that time I've used Delvac 1 in my diesel farm tractors and in my various motor vehicles, gasole and diesel powered. Sometimes the tempertarues have gotten to -25, cold by anyone's standards. With the unbelievabe pour rate of Delvac, it has repeatedly meant the difference between a no-start condition in both these tractors and motor vehicles. The total synthetic formula of this lubricant has also proven, over the years, to provide better lubricity, less wear due to reduced friction, and much longer oil change times than I would attempt or recommend to someone else. Today, there are so many flase claims by advertisers, and invariably so many of these items leave you in the lurch, so it is refreshing to occasionally find a product which is "trying to sell me the farm." Thanks kindly, C. Alfred Santillo

    First PSC is the only place I buy my truck oil, customer service excellent with fast shipping. Had a couple of -18 degree days and this product is excellent for Northeast vehicles.

    Purchased a Custom 2011 Ram Cummins 2500 Laramie Limited 4x4 Crew Cab a couple months ago with 39,423 original miles. Wanted to continue running Synthetic Oil, and chose the Mobil Delvac-1 5w-40. Shopped around for price and came across PSC. Order arrived fast and nicely packed. From now on it will be Delvac-1 and Fleetguard filters. Planning on keeping this truck a long time. Will be a repeat PSC customer. Thanks, Glen Pratt
