Oil Type Question


Recommended Posts

I have been running 15-40HD Delo in all of my vehicles for years and have had very good results. However they are changing the formulation and it is now sold as 15-40LE. I am told that it will be without one of the additives that is really good for the cylinders and block. There is a limited amount of 15-40 formulations to choose from.My Napa guy says their 15-40 is made by Valvoline? I have run Castrol and Valvoline in the distant past and had good luck with them. I am very particular what I run in my 240, and imagine many of you are as well. When I find something that works well I stick with it. Any of you have any thoughts on a particular type of oil? Happy 4th of July and thanks in advance. John
