only ever used Nulon 10w-40 fully syn, 347rwkw BA 4spd unopened

[SPOOLAX]

I have been using Mobil 5w-50, I must say it is a good oil though from when it had 264kw to a now 370kw, its has never had outstanding fuel econemy like other cars ive seen.

So my new choice is Nulon in my upcoming service.. but cant decide whether to run 10w-40 "hitec fast flow oil" or the 15w-50 street track mix.

Has anyone used both?? and can share some experiences with me?

Remember I am running 15psi @ 370rwkw, though I can say I dont thrash it too much.

I was thinking the same thing I use the 10w-40 now, but has anyone use the 15w-50 street track mix???

Yep I use the Nulon Street TRack 15w-50. I've been using the Magnatec 10w40 but on the track the oil pressure drops too low for my liking after about 6 or 7 laps.

Since I've been using the Nulon Street/Track the oil pressure is good all the way through to end of the session.

I even found the same when pumping through the hills, Magnatec starts to thin in the summer after 20 or so km of hard driving, then again the turbo is pretty red hot as well, but the Nulon has never given me low oil pressure.

I run the 10w40 nulon full syn in mine with 278rwkw. But once I go for my retune and other mods to make 330rwkw ill be swapping to the street / track 15w50 mix !

So where does everyone in Melbourne buy their Nulon oil? Spoke to mate who works at Repco today and he said they don't stock their oil and neither do Bursons.

Auto pro in NSW stock it and its generally always in the super crap catalogue

supercheap, and comes in 6 ltrs and 1 ltr bottles. im sure you need 6.7 ltrs. but not 100% sure.

[RHR]

FGs only will take 6l
