I put Redline MT-90 in mine three years ago. No leaks, and shifts smooth as silk in cold winter mornings. I previously had lots of grinding until the transmission oil warmed up much later.

What is "recommended" by Lotus is a Castrol product that is very hard to get in the US. As for what you can use, any good national brand 85-90W GL-5 Hypoid Gear Oil will probably be fine. The Workshop Manual A:05:01 says mil spec L2105C or API GL-5. Above -10c SAE 80. So if it's realy cold you have to go down to 75W. For almost everyone 85-90W will be just fine. You don't have to go synthetic, there will be no real benefit. The main thing is to have enough, and not too much. > David Teitelbaum > > --- In dmcnews@xxxxxxxxxxxxxxx, "stephen" <steve10000@> wrote: > > > > The PO of my car told me that he changed the manual transmission oil to "Redline 65". Well, its time to change transmission oil, and I am wondering a few things. First, I can't actually find this oil that he said he used. I have looked over the Redline site, and they make some interesting points about manual transmission oil that is "too slippery" being bad since the synchros won't work so well, etc. I note on my car that in cold weather I indeed have that occasional problem. I am contemplating going to more or less the recommended fluid, or maybe a synthetic like Valvoline 85W90. > > > > So, 2 questions:1) any other recommendations on manual transmission oil? 2) Regardless, when I change from one formulation to another, do I simply drain and add, or do I need to drain, add, drain again and add, to flush-out the other fluid? > > > > steve liggett > > > ------------------------------------ To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnewsYahoo!
