robmar Posted January 7, 2003 Share Posted January 7, 2003 whilst my petrol tank is out I am planning on checking my diff oil level as it is a lot easir to do than when the tank is in... I have some diff oil left in an already opened bottle from the build (18 months ago) which has been sat on the shelve doing nothing, would it be ok if I need to top it up to use that, or should I stop being a tight git and get some new oil. rob Link to comment Share on other sites More sharing options...
Roland Posted January 7, 2003 Share Posted January 7, 2003 Use it! Fluids such as brake fluid can absorb water, so that has to be treated with some caution. And some spirit based fluids will evaporate. Oil is ...1000's of year old already !! My dads old Morris 10/4 had a noisy diff, so some grease and sawdust was added. It went quiet !! (but only lasted another year or so 😳) Link to comment Share on other sites More sharing options...
F355GTS Posted January 7, 2003 Share Posted January 7, 2003 Rob It would be easier with the tank out but not essential. Jack the car on the chassis allowing the dedion tube ot drop, this will give you easier access to the filler plug (10mm Allen Key) Oil on the shelf assuming the bottle was sealed should be fine Mark Link to comment Share on other sites More sharing options...
robmar Posted January 7, 2003 Author Share Posted January 7, 2003 thanks for the replies, it terms of sealed I put the screw top lid back on Mark - yep I know you can do it with the tank it, but it is SO much easier withit out 😬 which is why I was going to check, I have no reason to suspect it needs topping up as it was checked out after it blew the breather out and some oil at atrack day 15 months back rob Link to comment Share on other sites More sharing options...
bl0498 Posted January 7, 2003 Share Posted January 7, 2003 Guys, Do you need a special oil for the ZF LSD diff or will the standard Comma EP90 do? I only ask because I am a little concerned about the occasional clonking from the diff at slow speeds when engaging/disengaging power... Any thoughts appreciated!

Grim Reaper Posted January 8, 2003 Share Posted January 8, 2003 I opted for Castrol B373,reccomended for plate type diffs but it does not have some of the sound deadening additives that non "Race" type oils have. A little noise never hurt anyone,and that authentic race whine just adds to the appeal of the car as a whole 😬 Link to comment Share on other sites More sharing options...
allegro Posted January 8, 2003 Share Posted January 8, 2003 I've topped mine up, lying under the car jacked up and on axle stands with a tube from the oil lid into the diff hole. What a nightmare and it's the most disgusting thing i've ever tasted, which is enevitable. It seems an imposible job without getting plastered in the stuff. Andy Mac C7 GON 😬 Team Langoustine.

Mick Day Posted January 9, 2003 Share Posted January 9, 2003 Allegro Next time take the boot floor out & do it from above - it makes the job much easier as you don't have to force the oil uphill. Same thing when topping up the gearbox. Get a long tube, feed one end into the gearbox filler & the other end up into the engine bay, attach it to the bottle & let gravity work for you.

darren f Posted January 9, 2003 Share Posted January 9, 2003 Another tip in addition to the 'do it from above'- get the oil warmed up first by standing the container in some hot water for a few mins- it runs in amazingly easily then Link to comment Share on other sites More sharing options...
DaveMorris Posted January 9, 2003 Share Posted January 9, 2003 FWIW the best way to get oil into a diff is using a syringe. Most (friendly) chemists will supply a large one (without needles) and a piece of rubber tubing does the rest. Those interested ( 🤔) can then see, and record, how much oil they have added. Dave M Note - my dad (just come in the room ) reckons that the easiest way is to get the man at the garage to do it. ❗ He's missing the point I think.

Mr Locust Posted January 11, 2003 Share Posted January 11, 2003 A large syringe the size of a grease gun is available for just such tasks from Machine Mart etc. for about a fiver 😬 Link to comment Share on other sites More sharing options...
