These engines really are not super sensitive to oils and ram only mentioned shell because its paid advertisement.

 

I agree with your concerns. Let's face it, a warranty claim upon engine failure based on wear is very subjective and will likely never happen or be approved as the cause. I hope RamCares will be able to answer your question. It may take asking your dealer for the properties and specs of both oil and additives, then pull a sample and send it to Blackstone to see whats really going on.

 

with a little bit of googling it appears that krex is nothing more than graphite suspended in some unknown liquid which they add to the oil for increased lubricity. They claim that modern oil can't withstand the high temperatures that new engines run at (BS) but graphite can. They claim you could replace all the oil in the engine with straight krex and run the engine with no ill effects (I'm skeptical). I'll admit graphite is a decent lubricant, but if it was beneficial to engine operation I'm sure every oil out there would already have graphite in it. It also seems that this additive is black as night when it goes in (makes sense, since it's graphite) but it will turn your brand new oil black instantly. You couldn't pay me to put that in my oil.

I'm curious why you even considered it if you already have max care

 

I’ve got a dealer provided warranty through RoadVantage which has similar language to what you’ve shared with regard to coverages. There is no mention of additional additives but they do have a 7500 - 10000 mile oil change requirement interval which I’m fine with. Your dealer wants PROFIT every 5000 miles.

If you’ve got max-care I’d tell the dealer you’re changing the oil per the manufacturers requirements and they can keep their additives.

 

To clarify, I brought the truck in for it's oil change and tire rotation on Friday. On Saturday I get an email with the details of this Drive Sure Benefits. In looking at the service print out, no mention of any additives were listed. It wasn't something that was offered to me and nothing was mentioned when I picked the truck up. I'm going to call tomorrow to ask what (if anything) was added in with my oil.

It boggles the mind that they'd put an additive in that clearly states needs to be changed out every 5k miles when the service interval for my truck is every 10k miles. Will this product start to break down or adversely affect the motor oil should it be left in longer than 5k? Who will cover the damage should this happen? I guess these are questions the dealership should be prepared to answer.

 

I'd be very interested to find out what engine oil they are actually using.

 

I had a 13B Mazda Rotary engine destroyed by using Arco graphite oil. If graphite was good for internal combustion engines, manufactures would all be clamoring to use it... my 2 cents. Same goes for teflon, imho.

 

You brought back memories, I too bought a 75 Rx4 Cosmo after a drunk driver almost killed me in my 73 Camaro... OMG, that rotary was totally awesome, lay scratch in 4 gears, 140 mph, no problem, but, when that front apex seal went at 35k, it sounded like a 60mm mortar going off out the butt end of that car...the laws stopped me and searched me for guns while limping home on one rotor, one thing that made me proud, Mazda, replaced that motor with a brand new one, no questions, arguments... fluids was my only expense... after 47 years, thanks for the memories,

 

On the OCI, every time I've taken either one of my diesels in for an oil change, they always come back with the little sticker showing next change due in 5000 miles. Over the 40+ years I've been driving and servicing my vehicles, I've seen a lot of fuel, oil, and coolant additives that were supposed to extend the life of your vehicle. It's all marketing smoke and mirrors unless your really abusing the car or not keeping proper maintenance. I'd go back to the dealer and ask for a refund.

 

Email sent out to dealer seeking clarification - I am not happy that they added something like this to my truck without my consent.

 

Update: I heard back from the service manager. She apologized that the service writer did not explain or talk to me about the new coverage they offer. She says nothing was added to the oil and the roadside benefits package was just something new they offered to everyone. Seems fishy, but okay. My oil is clean, not black like what is described on the internet. I'll continue to proceed with caution.

 

Then did you ask what oil and spec they actually use in the Ecodiesel? This is the important question. Maybe no additives......but they use a Krex oil.....lol 😆
