For the first time since I bought my 2019 6.7 F250 in December 2019, I am going to switch oil brands. I have used religiously Amsoil's Signature Series Max-Duty Synthetic Diesel Oil 10W-30 and will be switching to Mobil Delvac Extreme Heavy Duty Full Synthetic Diesel Engine Oil 15W-40. The reason is no shops will use Amsoil near me nor will they allow me to provide my own oil. I don't change my own anymore because getting rid of the used oil requires an act of Congress in California, plus at 75 years old I am too **** old to be crawling around under my truck and I have the money to pay so what the hell?
QUESTION: For those with 6.7s and who use Delvac, are you pleased with Delvac's full syn?
My odometer reads around 23k (I bought it at 17k) and I hardly drive it except on long road trips or to tow my trailer up into the mountains for camping. I have probably logged less than 2k since my last change with only one road trip from SoCal to Salt Lake City, but the dash maintenance clock has timed out at 12 months.
Thanks for your input.
