Mobil Delvac 1 ESP 5W-40

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

Very good oil, I've used it for around 20yrs and have had no problems, my motors run smoother and quieter and I have seen an increase in the fuel mpg. Also PSC is great, usually next day delivery, Thanks

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.

As usual the order was processed and shipped fast, this is the only place I go for my petroleum products

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

great oil little pricey but good

Just purchased a new Turbo-Diesel truck and need some oil for it. Great prices and fast delivery. That sums it up. Thanks for great service PSC.

It goes without saying that the product is excellent but the service your company provides is by far the best I have experienced

By far the best HD engine oil available today. Excellent cold weather starting capability and extended change intervals.

I ordered Mobil Delvac one for Mann engines. The best price you can ever find and the delivery was incredibly fast with $95 flat rate. I am very happy with this company!!
