Title: R380 on EP90 (oops) ATF
Post by: thermidorthelobster on May 28, 2009, 22:29:26

At the last service I filled my R380 with EP90, as recommended by another mud-clubber.

I've found the gearchange is smoother, I've lost the synchromesh clunk in second, and it doesn't feel stick-in-geary after long cruises like it used to.  So all in all it seems to have worked.

However I'm interested to know if anybody here has run an R380 on EP90 for a longer period of time, and if so, has it caused any problems?

i drained the ep90 out of my gearbox not long after i bought it, the previous owner had filled it despite being told not to

my gearbox whines in 4th and 5th gear and will soon need to be swapped, this improved with the correct oil in it but the damage was already done

I have it on good authority that putting EP90 in it will goose the oil pump and long term knacker all the bearings. I have only ever used synthetic in LT77s and R 380s just for that reason.

I ran an LT95 behind the Nissan in my old RR before putting the tdi/LT77 in it and found that every spare box I got for it that had EP90 in it had no teeth left on the oil pump, the recommended oil in those was engine oil,  good old 20/50 went in mine.

i'd ditch the ep and source some mtf 94 . or even atf . better than ep. you'll notice when it gets cold will be hard to get gears when cold ..

Dammit.  I'm a muppet.  It wasn't EP90 I put in.  It was ATF.

So same question, but for ATF!  Sorry!

atf was the original spec for the r380, but i think theyve changed to mtf74 now
