I got the capacity wrong...antony Mcgraph said 4.1 litres and some say 3.8 0r 3.7 , dont matter just fill it up until it spills out the filler hole!!
Some people say that Redline light is good ,some say its no good , some say that Redline heavy duty is good , some say no good..the point I was trying to make is that it sometimes doesnt matter what oil you put in ,it will not cure your worn synchros,but it sometimes helps. If you read around the forums any oil anybody has put in has different results .
Redline heavy duty is recommended for problem gearboxes and the light weight is not recommended for synchro type transmissions ( their words not mine) ...also the Redline heavy duty gearbox oil that I bought was red not yellow.
Anyway Im not sure about this bloke, he doesnt know what a fuel tank is !
