So , reserecting an old thread , anyone else used redline lightweight or even heavyweight , I'm torn between the 2 but as said by oilman , lightweight may be worth a go ?
Ok cheers, just trying to mask the dreaded synchro crunch the 5 speed boxes suffer with, im running castrol universal but the crunch is still there for 2nd and 3rd, seen some people say the lightweight redline has solved this issue, well, hidden this issue lol
I had a fourth-gear crunch - following advice from a US forum I tried a "cocktail" of one quart of Lightweight Shockproof plus three litres of regular 75w90. Worked like a charm.
Cheers guys, just ordered a bottle from opie Oils, will drain about a litre out of gearbox, add this bottle and see if any difference , bit wary of adding 4 litres of it as it seems to be a thick gear oil and some say it makes for hard gear changes when cold etc sow ill go for the mix option 1st
