Is your truck already using/burning a quart of oil in between changes?
The fuel dilution #'s are impressive, that's pretty dang close to my 98 after that many miles.
Are you planning on dumping the oil at 10k or pull a sample and continue to run? I understand their concerns, but they generally take a very conservative approach when giving recommendations especially since they are dealing with a new platform and have limited history to go by.
The Delo 400 LE 5W40 synthetic runs me about an extra $21.00 per oil change vs. 15W40 non-synthetic.And now to pick your brain if I may
What is your reasoning for 5w40 vs 15w40 previously mentioned?
I've used Schaeffers in all of my pre emission engines and changed at roughly 30k mile intervals (bypass filter included). This after my family began using it on their large scale dairy farm on an analysis program through Schaeffer.
My first oil change on this truck was also Schaeffers but only because I had a small surplus. With the EGR and higher oil contamination I'm definitely sticking to the 15k mile intervals which IMO negates the advantage of using synthetics. Currently I can buy a 5 gallon pale of Delo 15w40 @ around $60. Close to double that for Delo 5w40. (I can actually buy my Schaeffers for less).
Obviously whatever your doing is working well! Thanks for sharing your experiences.
