Synthetic oil & gear lube recommendations

[..P]

I've posted this stuff before in other forums, so if you've seen it there in the past, sorry, I just wanted to share it here too.

First of all, I’m not an Amsoil employee, nor do I sell this stuff. I’m an enthusiast.


My 928 now has both of the products noted below. I noticed no difference in the way the motor ran on Amsoil versus Mobil-1, but the Amsoil gear lube is real good stuff. Since it made such a difference on the way my 944 ran, I tried it on the 928 5-speed transaxle too, and it works well, but not as big a change as in the 944, perhaps due to wear and condition. Even if you have an automatic 928, you still need the differential filled with gear lube, and you could do a whole lot worse than use this stuff.

My 944 has 165,000 miles on it and had a whine in the rear end transaxle. I’m not sure what kind of lube was in it, I suspect it was Swepco. I changed the fluid with the 75W90 Amsoil synthetic gear lube, GL rated for the 944 of course, and it was almost as good as a rebuild. It stopped the whine and I can shift the car when cold just as easily as I could before when it was hot. Pretty good stuff and I recommend it. I understand Red Line makes a good synthetic, but since I have not tried it, I can only recommend what worked for me. This gear lube made a big difference in the way the car sounds internally, and in the way the transmission shifts. Good stuff for sure.

I also tried their motor oil, and the Series 2000 synthetic is rated better than anything else I know of. It is not cheap, around $8.40 per quart or so, but if you want the best, this is close to it. My 944 was shuddering under the 20W50 so I bumped down to a lighter weight and it “seemed” to help, although I have no idea if it was the oil or not. I suspect not. I could not tell any difference in the way the car ran, as I had been running Mobil-1 and may go back to that. However, the Amsoil tests out better.
