The jeep is a 4x4 and I did not have the 4x4 engaged. I know it has a ptu vs a transfer case. Could that PTU make a whining sound?

Prior to me purchasing the 2012 Patriot I had a 2010 Patriot 5 speed which did not make a single gear noise. There is no way that whine is normal, I've driven dozens of 5 speeds throughout my years and never encountered anything this noisy. Other than changing the trans, is there an oil you...

I have a new 2012 Jeep Patriot 5 speed 4x4. The problem is at highway speeds there is a constant gear whine. On the Jeep forums there are others with the same gear whine and to date the only remedy is to change the transmission. Chrysler's recommended trans fluid is actually an atf+4. The...

ok, thanks for the replies

I purchased my Jeep Patriot new 3 months ago. It's a 2010 and has the 2.4 (4 cyl) engine mated to a 5 speed. I changed over to synthetic (Penzoil Platnium)at 1800 miles and today I checked the oil and was a 1/2 qt low. I now have 4600 miles, is it normal to lose 1/2 qt within 2800 miles? The...

I have the 5.7 Hemi with the same heavey knock when cold, almost sounds like a disel. I had a stethescope on the motor today and it sounds like it's coming from a part that is attached to the motor it has two wires comig from it. I don't know the name of that part. But they may have used that...

I'm gonna try this my next oil change, later sucka's

I came to my conclusion based on the results from this testing, http://www.synthetic-oil-tech.com/Gear%20Lube%20White%20Paper.pdf

I have read that the Castrol Hypoy C 80w 90 oil is very good as a mineral oil, would this oil be suitable and what does hypoy c mean?

Wow, thank you so much for all the addtional information.

My mechanic who is installing this has a co worker who drags alot of cars and he was able to get the Royal Purple 75w 140 in a mineral base. I did order the Mag Hytec cover so it will hold more fluid. I am definitely staying with a mineral base, so do you think I should stick with the 80w 90...

I have a 2009 Dodge Ram 1500 4x4. I just installed an Auburn lsd and there manual says to use non synthetic 80w 90 and that synthetic is NOT recommended because of chatter, but my Dodge truck manual says to use 75w 140 synthetic. If I use one oil I lose the warranty on the lsd, and if I use the...

I am ok using a mineral oil but I put on about 6000 miles every two months that means I would have to service my rear at almost every oil change. Is it possible to push the drain interval for the rear to 12000 miles? Using mineral oil. Thanks for the replies

I have an 09 Dodge Ram 1500 4x4 and will be installing an Auburn limited slip next week. The Auburn instruction says not to use synthetic oil at all and to change the rear oil every 7500 miles. Is this correct? no synthetic and early changes? Thanks

In my Dodge Ram it has a 192 deg thermostat and the coolant sits at 194 and the oil temps are at 197, this is with outside temps of 98 degrees and a/c. I changed the thermostat from the original (203 degree)to the 192 degree.

Let me clarify my previous post, My original exhaust was a single 3" in/out and I went to a 3" in/dual 2.5 out. Would my current set up be cosidered too big of a pipe? And would you do a chambered or straight thru design muffler? Thanks in advance

This install was done three months ago along with the new magnaflo muffler. The Mopar cai is actually larger than the stock unit. There is no hot wire this is a speed density type system. I thought it could have been the new exhaust not having any back preassure. Also another forum member said I...
