So I bought my wife's Jeep TJ second hand and changed all the fluids within four months. I had already bought all the fluids from my usual jobber except the synthetic for the diffs. They don't stock synthetic diff oil because they recommend using conventional oil and changing it more often than recommended. (A practice that my brother swears by.)
I went to another jobber and they had the Chrysler recommended 75W140 synthetic. They were asking $20.00/liter. I was hessitant to say the least about spending that much money so they got out the charts and explained why Amsoil was the best oil to use. I wanted only the best for the Jeep and the Flyfisher was fished in and I came home with three litres of this junk.
It's 16 months and about 30 000kms later and this oil looks like conventional 80W90 with 230 00 kms. The magnetic drain plug has 1/2 inch of gear on it, I can just imagine what the bottom of the diff looks like.
I've used other synthetics in my Jimmy, usually a lot cheaper than this stuff, and they have never been so broken down as this stuff with three times the wear on it. I'm going back to conventional oil in my diffs and Amsoil had their one chance with me and blew it. I will never recommend or use another Amsoil product again except the Power Foam--even then only as a last resort.
I'm just fuming because to top it off the front of the transmission is leaking bad (probably the input shaft seal), The 4WD linkage is squeaking because a grommet has fallen off, and the front fender is starting to rust through. This is a '99 Jeep.
I expect a little more from my vehicles I guess. My wife hates it when I compare it to my '88 Jimmy that has been nothing but reliable throughout it's 465 000 kms--she's right, you can't compare GM to Chrysler.
