I would think this G70 is similar stuff and if others are using the full 125ml tube I think I still have some leeway.
G70 is not the same as ford/Penrite friction modifier. G70 is a type of friction mod designed to help make shifts better in old gearboxes but it also reduces the clunking in clutch diffs. It is 100% safe to use as it's a gearbox AND diff additive. It does not compomise the function of your synchros like ford/Penrite friction modifier does.

I don't see why using synthetic oil with a clutch diff is bad, a lot of oils specifically designed for clutch diffs are synthetic. I'm not an expert on the subject but I have been using this combo on the street and track for the last year and it's fine.

Yeah sorry it is an 80w90. I don't see why it wouldn't work though.
While running the 80w90 on cold it was so stiff getting out of gear was difficult and shifting would crunch intermittently, mind you it has brand new carbon lined synchros.

Apparently the synthetic oils leave a film. All the actual branded clutch lsd oils kaaz etc use a mineral oil.
But honestly after driving it today it's pretty good may just go penrite 75w85 with nulon additive and that will be the best compromise and ill just monitor it.
What's wrong with it leaving a film of oil? Once you start driving it'll get covered in oil anyway right?
Yeh but its different. Obviously oil will get on it... I'm explaining it inadequately but I found it online, it was a reply from kaaz regarding using fully synthetic redline products:

First, we do not recommend usage of Synthetic type oil but the usage will not harm the unit either. The only reason we don't recommend synthetic is because it creates a film on clutch friction surfaces and our plates don't lock and slip smoothly. Use of synthetic oil normally create more chattering noise because the lock to slip and back to lock operation becomes more abrupt using synthetic. The oil may quite down the unit initially but once the oil viscocity goes down, the noise will noticeably get worse.
Im not trying to rustle feathers with this, just want to find the best fluid for our application. So I guess viscosity will change in time once the oil breaks down. So I guess aslong as you change it regularly it should be fine?
Thought id post an update on experience with the oils. I changed out the OEM MTF with Ford friction modifier for the Penrite Pro Gear/Nulon G70 combo mentioned earlier in the thread about 5 months ago. Still clunks and grinds a bit when cold but when it's warm it's a sensational shifting feel and no grinding or clunking at all. Love it now!

Good to hear. With some LSDs the clunking when cold is kinda unavoidable, but once it gets some oil running through it goes away.
