topdog used to do my oil and oil filter changes every 6 months usually only reaching the 5000 mile mark. I would use the Shell Rotella T6 (5w40 synthetic) and either a Cummins or Mopar oil filter. The oil and oil filter costs me around $100 with tax.

I found a Ram Dealer about 40 minutes away from my house that gives me a great deal with their oil change package. I get 4 oil and oil filter changes I must use with in two years. So every 6 months I get an oil change with the Shell Rotella T6 (5w40 synthetic) a Mopar oil filter, tire rotation and grease the drive shaft fitting. It takes about an hour for the service with the multi-point inspection.

This is the third time I have purchased this deal, I can't go wrong for $285.00. Plus I don't have to deal with disposing of the used oil and oil filter. The good thing is this dealership will only allow their diesel tech's to touch the Ram Trucks with the Cummins, even concerning oil changes.

I know many are skeptical of having a dealership work on their truck, but I have never had a problem with this dealership. There is a Ram Dealership much closer to my house, however they only have one diesel tech and doesn't offer this type of deal. I had warranty work done several years back at the dealership where only one diesel tech was available, it took me several days to get my truck back. The dealership I get my oil change package at has 6 diesel tech's, I had warranty work done a few times at my current dealership with the same day turn around while I waited a few hours instead of days as with the previous dealership.

jazdad2007 Effective on all 2014 and newer 6.7 Cummins. They all come from factory filled with synthetic 5/40 due to they can not verify at time of build what climate it will be shipped to. Verified by Cummins engine supplier. Note, I have used T6 for 10 years without any abnormal noises!

2017-3500 I did my own oil changes
the first one at just 1000 miles and went right to full synthetic

I believe ring seal could be the only possible reason to start on petroleum based oil and even that would be questionable.... Certainly by 50 miles the ring seal is complete especially on a diesel, likely done by 20 miles

I build motorcycle race engines and get complete ring seal on full synthetic in sub 20 miles....... and run all these on full synthetic from initial assembly

bttravel Just a few comments on several items in this thread. I recently (May 2018) swapped out my 2016 2500 6.4L for a 2018 2500 6.7. At 11,000 miles and loving it!! Anyway, got 2 free oil changes from the dealer and had the first one at about 7800 miles. Oil, filter, joint lube and tire rotation. Quick background, I grew up in a Mopar dealership 50's, 60's and early 70's. Grease under my nails pre-puberty!!! Also police dept fleet manager, late 70's to mid 80's and service manager at Combo Chevrolet/Chrysler/Dodge dealer in my hometown. First comment is after my first oil change I quickly noticed the tech had set tire pressure to 40psi??? At 11,000 miles I checked the oil percentage life and it read 25%!! 25% in 4,000 miles?? Obviously the tech didn't reset it. That is unacceptable service and they were so informed. I've dealt with them for years but very little with their shop. They included a quote on their service ticket for full oil service and both fuel filters - $505.00, ouch. I'll be going to my little local privately owned shop that I've had do 98% of my work for 25+ years.
On another note I've had a lot of experience with Mobil 1 including when it first came out as a straight 20W to the present. Switched the entire police fleet over to it in late 70's and best thing we ever did. From that point forward during my time there we had zero engine problems or failures up to 110,000. Always been in my vehicles and is probably what I will end up using in the 6.7. Just wish there was a little cheaper but good alternative to the fuel filters. I'll have to get used to that! LOL

Jimbo & Truck I'm a second gen fella, 01 HO, and know nothing about new diesels, but I swear by Valvoline oil, Donaldson filters, Opti-lube oil fortifier, and most importantly Blackstone Labs ( oil analysis. I run non-synthetic oil 9K- miles and send in a sample for analysis for $20 +/- and get a comprehensive report on the metals, fuel, antifreeze, etc. in the oil. I feel the info that Blackstone provides in invaluable as it can help predict what is wearing in your engine and help you catch failing parts before something becomes catastrophic. They have fantastic customer service and will answer all of your technical questions via email generally the next day. $7 oil filter, $10-$12 / gallon oil x 3, $12 Opti lube, $20 analysis = $75 is cheeep in my book.

The EVIC doesn't follow the 6 month interval from what I've seen, only hours or miles/kms.

ttengineer Wow, that is phenomenally cheap. Granted Iím in Atlanta and the 3 closest dealers quoted me around $475 for oil and fuel filter change.

The only reason I called the first was because my wife is a teacher and they give free oil changes to teachers families. I had been getting my 1500 changed for free for 8 years there. They quickly informed me that diesels are exempt. So I asked price. I told the guy he was crazy when he quoted me $400+.

So I do it myself now. I run T6 Rotella, usually runs around $90 for 3gal at Walmart. I also bought a maintenance kit from Genos garage, also in Atlanta area, which comes with Fleetguard filters.

For the fuel I run a cat .4 micron filter inline with a Baldwin water separator. I only change the engine filter once a year. Usuallywith a nice wix filter.

Iíve thought about deleting the engine filter and also running a bypass oil filter to really extend maintenance intervals.

Remember oil (conventional, synthetic, or a blend) never breaks down, it just gets dirty and the better the filter the longer you can run it.

But damn $75 bucks, thatís a steal.

middleofnowhere The dealership service people are telling me that we should use conventional oil for 20,000 miles before switching to synthetic. I asked if they had a bulletin from FCA stating that and they said ďnoĒ. Somewhere I heard or read that FCA was shipping the trucks with synthetic.

I was planning on dumping the factory engine oil around 1500-3000 miles and starting on synthetic, but may rethink this a little. This is a recreational/personal vehicle for me, so I donít need to be on any budget or anything.

I put 270K on my old 5.9L 12-valve and the new owner had over 500K last time I talked to him, all on conventional oil Iím sure. My current duramax has been on synthetic since break in, >300K. Itís still like new. I started using synthetic in backhoe and generator after about 6000 hours, they donít get much use anymore, so I ďfeelĒ a little better knowing synthetic is sitting in the pan between operation.

I doubted it but made an appointment anyhow since it kept me from driving 60 miles to get my oil changed on a saturday.

They did it yesterday at 4 pm, the local wood river il dealer that is. And the final bill was $78. $20 for filter. 3 gallons of oil at $2.70 per quart, $32.40. Labor $20.45. Shop supplies $2.19. Sales Tax $2.73.

Notes on ticket say they performed lube, oil, and filter. Also 23 point inspection. It took them about 45 minutes.

Should I be worried something is missing or did I just get a good deal? I figured since they're a certified Ram dealer any errors would be on them.

Didn't know Wood River had a dealer LOL....(I was born there 1960-1971)

Youíll be absolutely fine with conventional oil of course, it just isnít what I will be putting in my new $60K truck.
Used them "without" problems once the warranty ran out....Still going strong when I sold it @ 452,XXX. They even stock the Mopar filter and I always had them put in a quart of Lucas. My Houston dealer has a 4 change deal (Rotella and a Mopar filter) for $275.00 and I believe it's nation wide accepted (I travel a lot).
