As a service provider, to my customers, I will not sell inferior oil. I will only sell the best and Delo 400 15W40 is the very best! My customers are very pleased with Delo, no consumption, no problems and no complaints. Personally, I believe that when it comes to oil you should not price shop, you should buy the best. I tell everyone that Delo 400 is the best diesel engine oil you can buy.
