For me protection qualities far outweigh a few kw...

in any case the variables could not be kept constant enough not to allow for slight variations...diff oil temp,gearbox oil temp,boost pressure,ambient air temp,the list goes on...vince is a nice bloke but this test means sh1t to me .

Not really into it cos they missed a few things like whether they warmed the cars up to operating temp e.g 80+ degrees for the oil and the rpms can never be accurate as your controlling them by foot so each run could be up to 100rpm off.

im glad motul did well though as thats the brand im sticking with and i run castrol edge in my beema.

i ran Repsol sythetic oil in my w/shop for over 5 years, also run it in my go-karts, have found it to be excellent. At the end of the day people all have their favourite, just make sure when you buy an engine oil that it has been API tested which is an independent testing proceedure that tests that the oil meets or exceeds the specs specified. Alot of oils on the shelf at your local auto part store have not had this testing, therefore might not meet the specs specified....it is a round stamp on the back of the container that will have API SJ/SL for example. It costs the oil company a pretty penny to have this testing, probably why they all dont do it. Also dont mix up oil grade with oil viscosity which is a common mistake. Running the incorrect viscosity oil could see you loose performance. while the incorrect grade could cause damage and or blockages in late model common rail diesels.

im not surprised the Castrol performed poorly. Castrol was a swear word in my shop lol.

I did a similar test on an STI once but never released it because the the STI was so in-consistant due to the " self learning" ECU it has.

Even with identical oil temp, air temps and same oil, it couldnt even do a back to back run that was similar ( it had a front mount so heat soak wasnt an issue)

Thats why I dont pay too much attention to these sort of tests. i look at oil pressure under various circumstances, engine wear and the oils condition after track days etc.

These tests are pretty useless, as has been said there are way too many variables that can't be controlled - one of the less obvious (but most impacting) variables being the climate / ambient temperature of the place where your car is driven/stored. Start up and cool down is where a great deal of engine wear occurs.

I use GW Sougi 6000 myself, but I sell the stuff so that's only natural :(

aside from the question mark of the fan being much closer in the nulon test, i'd also want a separate test of each oil run for 5,000km in normal driving and then a UOA done on it. I care more about protecting my engine than 5kw.

What up.

I should be here more, I'm a GTR fan that got lost and bought 3 Silvias

but you love them all :)

ive seen your ns sig

something along the lines of

my family is complete s13 daily, jet200 track and s15 missus car

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
