Hi all,

I am planning to flush my power steering fluid on my '06 CRD. In all of my previous Toyotas I have replaced the fluid with synthetic ATF and had very good results. I was planning to do the same with my CRD. Does anyone have any thoughts on this? I look forward to your thoughts.

On the topic of flushing fluids: does anyone have any thoughts on the best gear oil to use in the diffs, tranny and transfer? I'm planning on using synthetic gear oil (140 ish weight?) in the diffs and synthetic ATF - 4 in the slush box and transfer. Does this sound like a good idea?

Cheers,

Josh

I say go synthetic, but TJKJ should be along shortly to discredit that thought.

What exactly is the argument of synthetic vs dino and dino vs synthetic? I'm finally getting ready to change out my gear oil and I do a lot of towing with a 4,000+ trailer and I want to use the best option available. I posted the question once and TJKJ did recommend using the dino gear oil. What are the pros and cons of each?

ATF+4 is already synthetic.

For max protection for your diffs use regular dino 85w-140,80w-90 dino is fine for the front.With 12k-15k OCi's(yes it's that often because of syn gear oil) on the front and rear diffs why spend all that money for synthetic when dyno will protect better for cheaper.You can do at least 3 dino gear oil changes for the cost of one synthetic.This apllies to diffs only.The high flow rate of synthetic is not what you want in a diff without a added cooler.

I have used synthetic oils successfully for years. For the differential I use Amsoil severe gear 75-140 for the rear and 75-90 for the front. I do NOT use the 15K change interval, it was changed once at 5000 miles, again at 20k, and I didn't bother to change it again till 100K when it looked excellent. I also use a lube locker gasket on the back axle--it works well and saves a lot of hassle. For the transmission I have used Amsoil ATF successfully for years, once again, with change intervals at 50K or more. It depends on the driving you do--if the vehicle is going to be submerged or driven in dirt a lot, dino oil and frequent changes would be smart, for more non contaminating driving, synthetic save the frequent changes.

And have you used synthetic ATF in the power steering too? Do you know any reason why this would not work?

Thanks everyone for their thoughts.

Josh

I don't know when they started doing it, but the Libertys from at least 2005 come with ATF+4 as the power steering fluid. I'm not sure what the context of the argument is in this case.

Whoops, sorry. I should have researched this a bit better before asking. Sorry to tie up bandwidth.

For the power steering, instead of ATF I've used some stuff called Lube gard. They have a protector that stops squeaks and groans well. I also took out about 8 oz of the original fluid and replaced it with Lube gards power steering fluid. My experience with it has been good. I did not bother flushing out the power steering fluid.

For the transfer case I use some stuff call Tanzilla 150. It's an off brand, made in NY state, but it keeps the transfer case from sticking in 4WD.

No biggie...we're all here to learn. As long as the OEM recommended fluids work, it's convenient that you can put the same one in the transfer case, power steering pump, and transmission.

Mobil 1 makes an ATF +4 but this is a blend. Their full synthetic ATF has a higher flash point which may be safer if you get a leak.

I know many audi and bmw owners use Mobil 1 full synth. for power steering fluid.
I wonder if this would suite our needs?

Any ATF+4,licensed ATF+4,is full synthetic or it can not carry the ATF+4 label.

All the ATF+4's in the link below are the only approved ATF+4's and all are full synthetic.

http://www.centerforqa.com/licensedatf4brands.html

I know that AMSOILs ATF +4 rated oil is full synthetic and this is also a common choice but Mobil says that their +4 is a blend:
"Mobil Super ATF +4
Mobil Super ATF+4®, is a synthetic blend ATF"

at least this is what we get in Canada-
http://www.mobil.com/Canada-English-LCW ... plus4.aspx

I tend to pretty much be a fan of what the factory recommends unless superseded by a "higher" rated version of the same thing (ex. a higher test rated diesel oil)

That said ATF+4 means a specific thing and there are products that say they are ATF+4 but may not be. For a list of products that meet the ATF+4 specs as of April 2012 see http://www.centerforqa.com/licensedatf4brands.html

Amsoil is not ATF+4 spec'd,they will not submite to Chrysler testing to verify it actually is spec'd for use in Chrysler trans.Just remember most oils from amsoil are not even certified period in any way(including oil weight),use at own risk.

All spec'd and licensed ATF+4's have to be full synthetic as they can only be made from one of two base stocks and yes Chrysler tests them and on random inspections also.If it's not full synthetic it would have to be labeled ATF+3.

Chrysler may not certify it but how often do we agree or even comply with Chrysler?

Amsoil says:
AMSOIL Synthetic Multi-Vehicle ATF is recommended for transmissions, hydraulics, power steering and other applications requiring any of the following specifications:

• GM DEXRON® III-H
• Ford MERCON® & MERCON V
• Chrysler ATF+4®

As for "use at own risk", I am not getting into the great oil debate
I just wanted to know what people thought about using Mobil full synth instead of the recommended (in Canada) blend.


Have a look at the link that I posted.
Maybe you are saying that the word "blend" doesn't refer to synth\dino?
No sarcasm here; really like to know.

I have no particular ax to grind in the great "fluid" debate or Amsoil vs. the world. All I'll offer for Squeeto is both Mobil ATF+4® and Mobil Super ATF+4® are listed as licensed ATF+4 fluids and the license site, correctly, refers to blenders in the sense that ATF+4 is a blend of a base stock with additives (don't ask me I don't make the stuff or know anyone that does I just use it). Bottom line is that in order to be a licensed ATF+4 product the product must be independently tested and certified (includes periodic checks) and it either meets the standard or it doesn't.

As far as I am concerned we can debate which of those on the list are "better" but they all meet the basic standard. If one wants to use an "ATF+4" compatable product that's not on the list then be my guest. I don't plan to do so and I remember "universal" antifreeze.

Now, as previously noted, if a "higher" standard fluid is developed and certified to be backwards compatable with current ATF+4 that's fine by me too. Same as higher standard oil.

Squeeto - FYI apparently PetroCanada is one of only 2 entities that make the base oil stock from which ATF+4 is produced.

So, suggesting that Chrysler doesn't always know what is good for itself, how do you choose the better product? Not listed Mobil 1 full synth or listed Super ATF +4 (blended with conventional oil)?

I use the full synth in another vehicle (Audi). It would be nice to not have to buy both in bulk.

Hopefully nothing is getting lost in translation but I do know folks have had tranny problems using fluids other than ATF+4. The approved ATF+4 list has 2 Mobile products but does not include Mobile 1 Synthetic ATF. If you jump over to the Mobile 1 Synthetic ATF page I note that Mobile specifically does not list this product as meeting AFT+4 specs.

So my conclusion is if neither the approved ATF+4 list nor the manufacture of Mobile 1 Synthetic ATF are willing to list it as ATF+4 then I, personally, wouldn't use it in the Jeep tranny or any other DCJ tranny requiring ATF+4. Would it work, beats me I don't plan to experiment with my tranny.

Now would either of the approved Mobile ATF+4 fluids work in you Audi. I don't have a clue as I know nothing about Audi's transmission fluid requirements.

I was only thinking for power steering but fair enough stick with the +4.
The higher flash point for the full synth looked good to me though.
