TB Rich said:The later ELF Tranself NFP 75w80 seems like the one to get. Orginally Renault specified Tranself NFJ - which is a semi-synth and generally not very good, it's for 'low-loaded' gearboxes. NFP is fully synth and has a lot better specs including potassium borate which is a nanotechnology, intended for 'super high-loaded' boxes, including the 275 boxes with diffs etc.
Redline MTL seems well regarded, good pour point like NFP but it's a bit high (thick) on the viscosity at temp. Probably good for older/noisey boxes I expect - it would be my second choice for sure, it's a true GL4 so no issues with our brass syncros. But I've just had a rebuild so going with NFP first.
The other one people recommend on here, Fuchs Sintofluid. Well vs NFP & Redline it has worse pour point and sits in the middle of them in viscosity at temp. I think it's interesting that that new NFP vs NFJ is thinner, hence my reluctance to use the Redline or Fuchs as they are both thicker than NFJ, not thinner. Any way there is no compelling reason to by Fuchs, it's either NFP or Redline really.
I actually have Fuchs in my box right now for the last 12-18monts, it made no difference to cold start selection (which is why I changed) and obvioulsy now I've suffered 4th gear synchro failure with it
Elf NFP in there, silky as hell! Nicest feeling and change since I've owned the car (from 13k).
Opie's recommended me 75-80 fuchs too
They would as they don't sell Elf NFP (I think) ; )
Is anyone using the motylgear 75+90 of motul?its quite expensive but look a proper oil!
if the Renault oil is so good makes you wonder why the gearboxes fall apart so easily!!!
personally I wouldn't put it in the 197/200 gearbox would rather use another make of synthetic oil...
75-90's are all too thick, look at the 40 and 100 deg points. They'll all be much thicker than 75-80's.
ELF NFP is the best for these boxes, and on a worn/noisy box I think I'd go Redline.
Legend I don't know where you're based but Renault stock it..... you must have one around you?!
Yeah all 200's shipped with NFJ because that is what Reanult originally specified. It's crap oil tbh.
NFP actually had a spec revision because there were 2 sets of viscosity charts floating around. The later stuff now produced since 2012 is the better stuff and what you want.
The baulk rings, certainly on 3rd and 4th, are now steel not brass. To confirm that, as I've seen a few posts on this forum with uncertainty. So revisions have been made by Renault and touch wood with a much higher grade of oil and the new rings my box will be good.
