OK only my second post so here goes. The greater sheer strength and film strength of a 5W-40 vs. the Euro spec. 5W-30 would be enough for me to switch, to tell the truth I was going to do it anyway as soon as I got past my dealers free changes. Now that being said I called my Dealer today to schedule my next oil change and asked about the TSB oil spec change. He pulled up my VIN and stated that FCA had not attached that TSB to my VIN so they would be using "the standard oil", 5W-30 Euro, but if I had the TSB in hand I should bring it with me and we could talk about it. Now we have a software product at our shop, no names, which gives us a TSB update if we ask for a vehicle update, so after reading about the TSB for the 5W-40 Rotella T6 I looked it up and it was not present, again for my VIN, but was listed for the 2016 engines. The way I read the bulletin is that there are two functions, 1. the Rapid Response Transmittal which tells the Dealership that these steps need to be taken right now. 2. a Technical Service Bulletin which covers all engines made on or before June 30, 2016. Yet from what I am being told by my dealer is that FCA also attaches pertinent TSB's to specific VIN# for notification upon servicing and if my Service Writer does not see it, it does not exist.
About filters, I will pick between OEM online at $49.95 or WIX at $29.95, went to AMSOIL: website to see if they had a filter yet and they display a picture and PN of a WIX filter.
I absolutely love this truck, my first personal diesel, excellent fuel mileage that even with DEF cost is still below $.09 a mile, but, yes Mildred there is a but, when I start to factor in the cost of oil change I begin to wonder. My Chevy 5.7 every 5K $5.80 Filter 6qts 5W-40 full synthetic $15.00 1 can of BG MOA $20.00 vs. the diesel oil change cost which I will be doing between 5k to 7K miles, because I have seen what the extended oil change cycle has done to BMW and Mercedes engines. Rotella T6 now $30.00gl ($90.00) Filter low at $29.95 BG DOC $20.00 for a whooping $139.99 total, my cost without sales tax. Have a shop with Resale Tax Permit and wholesale accounts.
