How would the extra fluid actually get into the diff, im not sure how the lube system works back there and if you would recommend such a system, or accept one and reinforce it in your shop.
I'm no expert, but it seems to me like it simply provides for more fluid so that it doesnt get dirty as quickly. I dont really believe the whole lowering diff fluid temps since I doubt those gears get super hot to begin with, but whatever. I cant imagine it would hurt to have more fluid to circulate through the gears, but I wouldnt waste my money. Maybe spend it on an oversized baffled oil pan or something where it would be more useful if you want to provide extra capacity, oil cooling and prevent starvation.
S2KPuddydad, what do you think about running 75w140 diff. fluid in a stock differential for a daily driven S2K in stock condition 3 seasons of the year ?. I just put in Amsoil 75w140 to run in the upcoming season once the car gets put back on the road in spring. Any opinions on this viscosity ?. thanks for any replies.
thanks very much for the quick reply, I appreciate your opinion. I was using Amsoil 75w110 last season, when I went to dump it out it seemed to have a buildup of brownish sludge around the drain plug magnet. I wasn't sure if it was just cleaning out old buildup from fluids used by the previous owner or if the Amsoil fluid wasn't holding up. I thought I'd go up to 75w140 and see how it works. I took a used oil sample of the 75w110 and mailed it off to a lab for analysis but the sample got lost in the mail and it never arrived and I didn't have a second sample of that fluid, which really sucks. Is there any downside to running 75w140 on a stock setup ?, since I have it in the diff right now, I might as well make some use of it unless there is a negative to using it. Thanks for any opinion.
No the rear will be fine using it. The 75/140 is for heavy duty use and is just more than you need for your DD S2000. It is a bit more heavy and may hurt the MPG but not by any big deal.
