So I changed my oil this weekend and I didnt notice till I was done that Delo had changed. You can no longer get just the 15-40 Its now formulated for the new low emissions diesels. I just dont know how its going to work in my truck. It says its fine for everything but i hardly belive that, any ways anyone have any thoughts

Yes, you can still get Delo 400 15w40 in the CI-4+ formulation. Many places will only stock the Delo 400 LE which is a 15w40 in the new CJ-4 formulation. The new oil will work in older engines. If you have doubts about whether the oil is working in your engine have a couple of oil samples taken. You need more than one sample to get an accurate idea of how the oil is doing.
