Differential info - maybe important

[ochten]

I use Rowe Hightec Hyoid racing oil EP 75-140 s/ls. Not expensive and tested on the Nurnburgring. Smells strong at fosfor. Is a anti weldingdope I think.

The old oil is so thick and nasty that I put some engine flush in and turned the diff by hand to try to mix it up

It would be much better to drain when hot, but not an option for me at the moment

I'm tempted to put some flushing oil through it before filling it with expensive Lodexol
