Change factory fluids ?

Hey guys, gt myself back into a ram. In sig. Just got it delivered thursday.

Hard searching for this question so figured would ask. Do you guys like to change out the trans/differentials/transfer case fluids after say 1000miles or do you all like to just stick to the recommended interval.

My truck is a 2014 with a build date of Jan 14 so I figure I should change the oil out regardless just due to the time its been in.

I was thinking the geared parts usually have a little more wear products in them when doing the initial break in.

Thoughts/recommendations.

With the new synthetic oils I leave the gear/trans oil now until around 30K. My engine oil I changed at 3K and will follow every 6 months. I will never reach over 6K on mileage so it's every six months for warranty.

Agreed. All of your fluids should be synthetic minus the engine oil so it's actually pretty good stuff. I just did my first oil change at around 3k as well and will stick to the 6 month interval for warranty as previously stated. I might get one more oil change with conventional but plan on switching to Rotella synthetic for the future.

I'm pretty sure the engine comes with synthetic too from the factory, at least that's the rumor. I changed my engine oil at 2500 just for that warm fuzzy feeling, put valvoline premium blue extreme 5w40 back in because that's what I believe the initial fill was, will change every 5,000 or so from now on. Changed the rear diff fluid at 1,000, not for maintenance but because I put on an aluminium cover on. It was clean as could be at 1,000 miles... Lol

I changed my engine oil a 3k and 7k, and my rear axle at 10k.

The factory fluids are good, but for me it was a 'just in case' thing.

I just passed 10K on mine and the factory fill oil is still in it, will probably get it changed this coming week as I have the 2 year service contract for 6 oil changes at the dealer, but the oil life meter says I have about 30% left, same with the fuel filters.

Of course, my truck is only 6 weeks old...
