Yes, a 75w-90 high quality dino would be nice. What did you use? Valvoline had to add this:quote:

HYDROTREATED NEUTRAL OIL C15-30 72623-86-0 28.0- 38.0%
to their dino gear oil to get 75w-90. I'm not sure how this affects the robustness of the gear oil. I don't get the impression around here that valvoline is the greatest gear oil.
The 201 is also an 80w-90. Swepco makes very good products, but the ~$50/gal I'm seeing seems to be about as much as you can pay for a gear oil (except maybe NEO), and we're not talking about an ester base here, just a dino with a good additive package. I'm sure it shifts at least as bad as the delo 80w-90 in the cold.quote:

The Swepco 201 is new to me. There is a rumor that there is a Porche somewhere in the country, but I haven't seen it. I'd be curious to see an analisis of the Swepco 201. Might give us an idea.
Thank you for clarifying that, widman.quote:

The Delo is for top-off only on LSD. At one time one of their technical people told me it was good for complete fill, and the Spanish version of their spec sheet said so, but when I put it in my 4Runner it gave grinding noises on U-turns. That's when I noticed the difference between English and Spanish spec sheets and questioned them. Their reponse was NO complete fills on LSD, and they corrected the Spanish sheet.
Does anyone have an opinion on the theory that synthetic + LSD additive causes the problem?:

A few people have had bad results with regular OTC small container Mobil 1 75W-90 (contains friction modifier), slow shifting and grinding. Perhaps this is the combination of the friction modifier and the synthetic. I would be wary of using a synthetic that already has a friction modifier in it due to others' results. However, something like the redline 75w-90ns or the Mobil 1 SHC 75w-90 with a careful dose of friction modifier might work well. As I mentioned above, one guy adds 10% Dow Corning Molykote M to 75w-90ns redline and doesn't have LSD chatter. A single quart of Molykote M is $40 though!
