Hi there! Great forum, I've been a Landie owner for a few months now and so far I'm really enjoying it! I brought a E reg 90 V8 County with a LPG conversion, all has been well so far but I plan to give it a good seeing to soon - I mean change all the filters, fluids and ignition componants, nothing perverted!
First query is regarding oils. I understand the main gearbox takes engine oil, is this correct? I only ask as after reading some good things about Difflock oils I took a look at their site and see they recommend gear oil for the main box, but in my Land Rover manual it states to use engine oil? The gearbox on my vehicle is the LT85 I believe... If it does require engine oil, has anyone a recommendation for which oil to use? I plan to replace the transfer box oil with Difflock's Evo 2 which should be ok, yes?
Also why I'm on the subject of oils, has anyone a recommendation for which engine oil? Are synthetic oils suitable for the V8? Are cheap oils ok as long as I change them reguarily? Or should I go for quality mineral oil, Castrol for instance?
Next query is about the LPG conversion. I have a switchable system with a TD5 style underslung tank, it was converted by a company in Devon professionally - I have certifates. I can't remember the name of the company off the top of my head. Anyhow I understand that with LPG the ignition system needs to be in tip top condition and the rover V8s have a weak ignition system anyway. So am I better off buying OEM leads and replacing them regularily or spend a bit more on some performance ones? Again, with plugs what am I better off buying? Also is there a better/performance coil available? If there is, is it worth it? Or, again, am I better off with an OEM item and change it often?
Long post and lots of questions I know - apologies for that! Any help/suggestions much appreciated,
Mark
