ferny Posted September 6, 2015 Share Posted September 6, 2015 Be careful, cheap oil is normally cheap for a reason and ends up costing you more in the long run. Stick with something you know to be good unless it's something on its last legs which you don't care if it dies.I'm currently researching the below oil as all I can get around here is Comma branded stuff and I'm not a huge fan of their engine oils, ie, wilko, halfords, etc...http://www.opieoils.co.uk/p-60148-gulf-gear-ep-heavy-duty-gearbox-oil-80w-90.aspx Quote Link to comment Share on other sites More sharing options...
Clive Posted September 6, 2015 Share Posted September 6, 2015 BGH who build rather tasty gearboxes for competition/kitcars etc recommend the Comma 75-90 GL4 semi synthetic. I bought some for my T9 box, but suspect it would be more than happy in the diff too (now my diff holds oil again!)I know there are some very good gear oils out there, but I have always bought the comma ep80-90GL4 stuff, usually in 5L tubs......

Nick Jones Posted September 6, 2015 Share Posted September 6, 2015 I use the Redline Shockproof in my diff and Redline MT90 in the (toyota) yearbox. Both from Opie.Nick Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted September 9, 2015 Share Posted September 9, 2015 I've said this before - always make sure you use GL4 in the older cars. GL5 has some detergents in etc that will corrode brass etc so it's a sure fire way to buggar up a gearbox for certain! Quote Link to comment Share on other sites More sharing options...
Hogie Posted September 9, 2015 Share Posted September 9, 2015 Hi Jonny, not so much detergents but sulphur etc.Roger Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted September 9, 2015 Share Posted September 9, 2015 Fair enough, I read it was the detergents, but the end result is the same that your gearbox will eat itself very quickly. Quote Link to comment Share on other sites More sharing options...
GT6 M Posted September 9, 2015 Share Posted September 9, 2015 Errr no really, the info is olde stuff, that just is being re gurgitated.the OE GL 5 stuff did this, but it eat stuff away.the boffins got at it, and its OK.BUTT no for G Boxes, as its tooo slippy, so syncro rings will go.there was / is also a GL6, but info says its obsolete, true, just its no been tested to modern standards due to its limited use.as it were meant for a 425 / 385 HP front wheel chain drive Toronado Me sell, I use the 80/140 stuff, its thinner when cold, but thickens up when hot like a multi grade oil.Note, gear oils are rated diff to engine oils,a 20W engine oil is v v similar in thickyness as a 90W ger oil.AND change it regulary if ye want yer diffs to work oktek a hot gear oil oot and its like v v thin pish,thats why I like some thing thicker when yer diff oil can get to 150 degs as mine has been measured after a long blast.M Quote Link to comment Share on other sites More sharing options...
