So guys I am going to be doing all of my maintenance on the truck as I have an aversion to the dealerships as I have seen several issues with def being placed in the diesel tank, oil filters not properly tightened, fuel filters with o rings not properly lubed and placed etc.. anyways I am looking at what type of oil is best. Deliberating between Rotella T6 5-40 and Valvoline Extreme Blue 5-40. Anyone have experience with the Valvoline? I've used rotella in my 6.0 and ecodiesel and never had an issue but thought maybe I should give Valvoline a chance
hey guys! I have an oil question ---- I thought I understood the oil numbering nomenclature; for instance 10w-30 vs 5w-40 -- the first number 10 followed by W is the cold flow viscosity (5W flows easier than 10W when the engine is cold). the second number is the viscosity once the oil is warmed up (around 200 deg F or so). 30 would be thinner than 40. so here's my confusion -- why the heck does the owners manual say that 5W-40 is only for cold environments and 10W-30 is for warmer environments? shouldn't the 5W-40 full synthetic be the absolute best in both warm and cold environs? I live in MD, where the winter nights can be 10 deg F. and in the summer we get near 100 deg F during the hot days. when my first oil change is due, I was initially gonna put in the Rotella 5W-40 T6, but after reading the manual now I'm not so sure. I can't understand why they would say that in the manual??
You are correct in your asumption, i agree ... I think the owners manual is bogus as far as oil recomendations go ..in the weights they suggest full synthetics diesel oils are of a limited selection.. I am going to run rotella t6 ... The exception might be up north where the temps are not as moderate in the winter then i might switch to a oil thinner oil .. But the oils in the manual will work well too.. Xxx
I have the 2016 Titan XD Diesel, should I go to Nissan to have them do my scheduled service, or will I be okay with using my mechanic that has been working on my cars for the last 7 years? This is my first Truck, and diesel. . . Nissan is wanting to charge me $550 plus tax for my 20,000 mile checkup/maintenance. . Please advise and thanks
