When Is It Ok To Change To Synthetic?

[06 Dodge]

Lifters, piston rings, crankshaft and bearings are all new designs. The block is even CGI

Interesting to hear

Get some T6. Your good to go!

Amazing amount of bad advice. The 2022 truck engines (any built after 2016 actually) have much tighter tolerances to allow for using lower viscosity motor oil to improve fuel economy. The question is not synthetic versus blend but rather which diesel motor oils provide the best additive mix to compensate for burning diesel with is a very dirty fuel.

In the past the independent lab evaluations have put Valvoline Blue and Pennzoil and Rottella and Redline in the top tier in terms of their additive mix. Amsoil and Delo and others have been in the bottom tier.

The multigrade to use depends on the temperatures where you drive. In ambient temperaturs above 0 degrees F, a 10W-30 is recommended. Below zero degrees a 5W-40 is recommended.

If you cannot find your owner's manual then you can easily download one from the ramtrucks.com website.

Hello. I couldn't find the answer to this. 2022 Ram 2500 6.7. I am about to change the oil for the first time as soon as my filter arrives in the mail. I am going with Rotella as Valvoline Blue is hard to find here. Is it OK to go full synthetic with only 5500 miles on the engine?
We tow a camper for work where ever we are sent across the country. Which would be better protection for towing Rotella T5 10w/30 or Rotella T6 5w/40? Thank you.

Switch anytime…. I run Amsoil in everything I own and in my opinion, it is a superior product

That's what I thought to until I changed my diff oil which was Severe Gear. There was a lot of burnt oil baked on the aluminum cover & the oil was almost black. Grant it I tow some with this truck, but that oil had only been in there a year. All the test that I had seen this oil did very well, but the actual test in my diff, it failed big time!

I used Amsoil Server Gear in my 2006 2500 CTD for 12 years never had a problem, when I pulled the cover gears looked good and clean...

I have never owned a diesel and my experience doesn't apply.

For every gas V8 or 10 (also GT2 & 3) I run Mobile 1 0/40w synthetic. I like the instant oil pressure rise and extended heat this oil can take. I drive my cars really hard and/or/with sustained high speed...or I used to (I'm over it). This is the best oil I've ever used, and I can buy it at Wal-Mart or Costco. There is no condition this oil isn't good at. This oil is never a problem in extreme heat or summer track days/weekends. Don't be scared of the 0 - it works perfectly in the summer as well.

“Lifters, piston rings, crankshaft and bearings are all new designs. The block is even CGI”

Is that true for both the SO and the HO?

The difference between the SO and HO is pistons, injectors, and programming. Everything else is a shared component.

Speaking of bad advice/bullshizit...........Bearing clearances and ring/cylinder/piston clearances haven't really changed much in the last 40 years, and those are the parts that rely heavily on lubrication to survive. Besides, the thought of building a tighter engine just so you can use lower viscocity oil is just plain dumb.... The lower viscosity oil is used because it can be used - The oil's ability to not shear under loads and heat has increased with oil technology, and oil that flows easier(lower viscosity) produces less frictional losses resulting in more efficiency, and it also carries more heat away from critical parts resulting in longer life. This is evidenced in synthetic (nylon-based) oils...they flow at lower temps, breakdown at much higher temps, and do a better job at integrating with additive packages to remain usable for longer intervals.
