Valvoline gear oil
 
Just purchased some Valvoline 75w140 synthetic gear oil. Anybody used this before or am I the goat? Also bought the additive. All opinions are welcome.

Check out this info I posted in the wk2 thread.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~

Some interesting information I found on google... Scroll to page 19 if you just want a quick read, It shows the end results. or skim through for a more in depth look.

The Mopar oil didn't fair to well. I also read Mopar gear lube is re-branded Shell. Another reason they recommend Shell or equivalent for the Transfer Case in the manual I assume.

I've used all sorts of gear oil (including Valvoline) over the 11 or 12 times I've done the diffs - never noticed one as better than another (and no gear whine at 150,000 miles),

I'm having my transfer case and differentials done with Amsoil products this time around.

Thanks for the link J13ntv; I'm also switching to Amsoil next time around. I managed the physical characterization lab for a Major oil Company 25 years ago, and our lab ran most of the tests they describe in the link. No more Mopar fluid after seeing how poor it compares.

Re: Valvoline gear oil
 
Not to sound overly negative, but are the above tests really meaningful in daily applications? Sure, I could find 100 different lubricants that protect better than a lower cost one...but over the few 100,000 miles I keep the vehicle, is that extra protection going to make a difference?

I drive an average of 25,000 miles a year, and have yet to have any problems caused by gear oil on any vehicle I have owned. If you swap it out at the regular intervals I would bet the lowest quality will be fine.

Obviously, everyone is going to go with what makes them sleep well at night - and they should, but just because a test says one lubricant is better than the other, doesn't mean it will have any real world implications over the typical service life of your vehicle.

I think it is all about the specifics of the vehicle conitions - towing, extreme temperatures, long periods between service intervals, etc. that really makes the difference in selecting which product to go with....not a company sponsored series of tests designed to show superiority over competitors...

THe Mopar fluid is much more epensive than the Amsoil, plus you need to buy friction modifier. Increased mpg with less drag from the ELSD's would be expected over the Mopar fluid. I'll find out shortly. Amsoil is also cheaper than Mobil 1.

I used Mobil1 last time around and it was about $15 a quart at the local autozone. This time around the price went up to $20 a quart.
I decided to order some amsoil under a friends account and paid about $14 a quart.
Personally, amsoil vs. mobil1 vs. oem vs. Valvoline vs. anything else.... don't care... I drive about 30-35k a year and have never had an oil related issue due to "brand" of anything. The key is to change it periodically....:thumbsup:
