Was kinda hoping they would do redline as well.

Does anyone wanna add some info on australian guidelines for labeling on oil? e.g. why motul will say 100% synthetic +ester and why do most of the rest use 'full synthetic'

I thought that the Castrol Edge is a hydrocrack mineral oil type synthetic, making it a Group 3 and the Motul 300v and Mobil 1 are a Group V poly ester man made oil?

The oil thread has more info than you'd ever care about. All I know is that my car seemed to run better on Motul 8100 Xcess 5w40 which is a Group 4 oil than the Castrol EDGE 5w30.

The oil thread is very good, has a great summary of oil classes.

Im a big 8100 xcess fan as i used to use 300v but at 150bux a change every 1000kms was a lil overkill.

you don't need to change every 1000km's, especially with such a good oil like 300V - 10K is fine, or 6 months, whichever comes first.

Castrol EDGE seems to be a Group IV, and i guess a pretty cheap group iv at that (i swear when it first came out it was a III) but it seems there is a 'Sports' version that may be a Group III (gotta do some more digging)

Mobil 1 is a funny one, as with a few oil brands it depends on what weight/viscosity you get. Ie, a 0w30 could be a Group IV+ but the same named oil in 10w40 could be Group III. Makes things confusing and i know Mobil 1 has copped some heat regarding some of their range.

Mobil and Castrol are generally a little cagey about what base stock everything else, but you're always well off to do an UOA anyway.

If you really want the absolute best, just buy Redline.

in my experience the results of the oils can vary depending on the engine types, considerably. Some engines just like some oils more.

I run Castrol Edge in my skyline on the advice of Guilt Toy

I run Penrite HPR40 in my sigma as its proven to perform in the 4g54

I'd be keen to see a test run by Top Gear or something testing oils across the same car completely impartially. I once read a magazine article ages back that compared oils by subjecting it to a friction test on a peice of steel round bar against a metal plate. The resulting wear or lack of after X runs showed the best results. Royal Purple, motul and penrite all did very well. Edge wasnt around then...

An oil isnt proven by a poofteenth of a kW on a dyno, its proven by wear, temperatures and the way it looks at each oil change.

exactly!

what kind of retards base their choice of oil an a few kws difference on a dyno. a suss dyno at that.

those tests fail in every department.

Yes all that magazinbe article showed was that it is pointless testing an oil the same way you would test grease.

An oil will generally allow the motor to develop more horepower if it has a lower viscosity & more friction modifiers in it.

With regard to how it looks when it is in your sump - usually the blacker it is the better it works to absorb the crap that would otherwise be left in your motor. Ofcourse if it is the oil itself doing this you are in a bit of trouble....

Have to agree about not choosing an oil based on a few kW... Personally, I'm a bit more interested in the properties of the oil as a whole. The whole test seems a bit strange, nice work on spotting the fan distance pics. Some unusual variation there...

Won't be switching any time soon, sticking with Motul in the R34.

An easy way to tell if it is the crap from the engine or the oil itself is to take note when draining the hot oil during a change.

It should come out black initially, but the oil should not be black when it gets to a light drizzle (the crud comes out mostly early on when you drain the oil).

      Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
