V7 SLR Posted July 15, 2003 Share Posted July 15, 2003 For a Caterham 6-speeder MTL = 75W80 GL4 MT90 = 75W90 GL4 Why one over the other (not terrib ly important, just curious)? And can you remember how much is needed? Demon Tweeks sells it in quarts. Will one do?

Bare Posted July 15, 2003 Share Posted July 15, 2003 recently ran across an interesting bit on a Honda Racer's Forum.. Seems Redline Gear Olis are being blamed for several transbox Failures.. Seems the Oil is "dissolving" the plastic ball cages on the Honda Transaxles.. with understandibly horrendous results. Just Food fer thought/caution.

Peter Carmichael Posted July 15, 2003 Share Posted July 15, 2003 MTL works very well in mine. Some have suggested that for warmer ambient conditions MT90 might be appropriate - no experience I'm afraid. Link to comment Share on other sites More sharing options...
V7 SLR Posted July 15, 2003 Author Share Posted July 15, 2003 Problem with the Shell Helix currently in my box is that it offers a terribly baulky change when cold. After 3 miles it's great again but I'm worried if I'm damaging the box when it's cold.

Nick M Posted July 15, 2003 Share Posted July 15, 2003 I used to use a Millers fully synthetic oil (on the gearbox makers suggestion I might add !) and the change was never really baulky when cold but it was slow shifting up at full revs even when hot. Swapped to MTL and it improved the cold gear-change (I was concerned it might be notchy or baulky, but it isn't) as well as full rev changes when the oil is hot. I'm pleased I made the change, put it that way. Link to comment Share on other sites More sharing options...
V7 SLR Posted July 15, 2003 Author Share Posted July 15, 2003 Right then. A bottle of MTL is on my shopping list. Thanks. Worcs L7 club joint AO.//Membership No. 4379//Azure Blue SLR No. 0077//Se7ens List Tours Link to comment Share on other sites More sharing options...
Nick M Posted July 15, 2003 Share Posted July 15, 2003 FWIW, 1 quart bottle = about 0.9 litres. I can't remember how much the Caterham box takes but I always seem to need about 1.25 litres to fill my gearbox (alloy cased type 9), so maybe two bottles might be an idea ??

CHRIS CLARK Posted July 15, 2003 Share Posted July 15, 2003 Two bottles is right (although you won't use it all). Changed to MTL a while back and it has created a very slick changing 'box now as opposed to the baulk/stiff when cold one that I used to have!! Ooh Err Missus. MTL is also 'approved' of by Phil Stewart; Road & Race Transmissions head honcho. Link to comment Share on other sites More sharing options...
Chelspeed Posted July 16, 2003 Share Posted July 16, 2003 and it's US quarts too which are smaller than proper quarts. Thought everything in US was meant to be bigger? Link to comment Share on other sites More sharing options...
John Vine Posted July 20, 2003 Share Posted July 20, 2003 Or you could use Ford red (p/n 5015547) if you can still get it (now discontinued?). I use it in my 6-speed and it works a treat. Mind you, at around £11/litre, it's not cheap -- but then, nor is the box! JV Link to comment Share on other sites More sharing options...
martinwhitcher Posted July 20, 2003 Share Posted July 20, 2003 Ford stopped the supplying the red oil without telling anyone i think? that's what started the whole problem in the first place! MTL is the oil for the six speeder Martin MW 51 CAT Edited by - martin whitcher on 20 Jul 2003 19:12:50 Link to comment Share on other sites More sharing options...
alicat Posted July 20, 2003 Share Posted July 20, 2003 V7 SLR I had the ususal mineral oil in my 6 speed, it was changed at the last service (don't ask what to, all I know is that it is not EP90!!!). Gear change is far far better when clod, although, the box sounds noisier when warm. Alicat Link to comment Share on other sites More sharing options...
