Bit harsh mate, am intitiled to share an opinion based on scientific facts, i did state, ( from what i have read and heard, googled etc..) no need to be like that...

if you dont like what i say, then dont comment, i thought this forum was about facts, info, helping people, whats your info based on?? show me??

Your understanding sucks :)

From my understanding OIL is very important in protecting against metal/metal contact. Nothing wrong with SM. Many other parts in your engine will fail before it succumbs to the "adverse effects" of an SM oil.

[/quo

SM oil is formulated for brand new engines not older engines such as r33's, it wont damage engines its just not the very best oil, thats all im saying,

is redline, motul, royal purple oils a SM??? no.... cause SM criteria says to have lower levels of stuff like Zddp, these race oils all have high levels of it because its important, therefore SM isnt the best oil...

you can use castrol magnetic if you like, but doesnt mean its the best oil..

there is no such thing as a best oil and there never has been, not 300v, not mobil 1, not anything

different applications require different oils.

to say that mobil 1 is/was the best oil is therefore false...

also i was only having a harmless pisstake.... no need to get your panties in a knot

Don't use magnatec :P

Though zddp is a unparalleled oil additive it's important to remember there's a lot more to oil than just zddp. Zddp is one of literally dozens of additives to oils to reduce friction, and the reduction of zddp in oils is nothing new, the zddp level has been reducing for decades.

One thing you may not know is that often concentration doesn't matter as much as people think. Doubling the concentration of an additive almost never doubles it's effect. Further, once a certain concentration of zddp is reached it won't benefit the lubrication mechanism by adding more.

Also, zddp is known to damage catalytic converters over time, so unnecessarily high concentrations won't be doing any favours.

cheers for that reply, bit more useful than the previous few..:thumbsup:

Im no expert but when researching about oils on net, ZDDP comes up alot, the recommended level for best protection is apparently up around 1400ppm, The API standards stipulate that newer generation oils have less of ZDDP, so eg Mobil 1 SM rated, is now about 800ppm,

so although it may not be the only additive it seems to be an important one none the less.

Give them time and they will be. What you're describing only affects old-old vehicles, talking pre 80's shit. Skylines are perfectly fine to run on the latest oils. My issue is that it's misinformation to say SM oils should be avoided, when your reasoning is the reduction in content of a single additive that does not have the kind of impact you're suggesting it does.

It really is one of the last things I'd look at in the line of selecting an oil. You've probably attributed your car to running differently based on your ZDDP content, when the reality is that you've now got a thinner viscosity oil / different type, and cars always feel different after a fresh oil change.

Hey fellas just a heads up to all that love a good lube. I hope this is the right place to put this moderators. Just to let you guys know that Harold at PerformanceLUB (www.performancelub.com) is having a special on redline 10W40 (good for the winter season) for $18/qrt instead of usual $23/qrt only if you mention my name (Nik). This is the cheapest price on net (including ebay)!!

He has other brands and products like Amsoil Oil, Royal Purple oil, Royal Purple XPR, Royal Purple Max Cycle, Castrol Syntec Edge ( German Castrol), Mobil 1 EP Extented Performance, GReddy Rotary Oil, NGK iridium IX & G-Power Platinums Performance Spark Plugs, Full synthetic engine oil, K&N Oil & air Filters, Philips Xtreme Vision Bulbs. I've checked out the prices of some of the items and they still seem to be cheapest on net even if you ordered products like ngk iridium sparkies from overseas - go figure.

Some of you would know him already and have dealt with him. I've had no probs and in one purchase just bought oils for everything on my dirty2. engine, diff and gearbox. Only charged $25 for 16kg worth of oils through fastway.

Send him an email with my name somewhere in it to: [email protected] and I'm sure he'll help you out. He knows his oils so ask whatever you want to help you make your mind up. If you go through ebay you may miss on discounts since he has more fees but going directly through him and paying by paypal (which is what I did) I'm sure he'll sort you out.

Remember this is a suggestion - research for yourself first before making up your mind. BTW I am not getting any sort of kickback from this. But you won't be dissapointed.

Eat it

General mechanics usually carry 15w40 and 20w50 mineral oils to keep running costs down. These two oils will help service 95% of the cars they come across. The game is changing though, with many modern cars that call for 10w30 now entering their "non-genuine servicing" ages...requiring general mechanics to carry specialist oils too.

Most workshops that I supply oil to, I have convinced them to keep only Syn-X 10w40 and Hi-tech 20w50 in stock, as Syn-X is only slightly more expensive than mineral 15w40 by the 205 drum, and can be used where both 15w40 or 10w30 are needed.

yeah its just a price issue.. suspected as much, in my cars i run

93 skyline gtst...130km....motul 8100...5:40

04 accord ...155km...peak ecosyn 5:30 ( no reason just thought id try it )

bt59 TD...80km....penrite hpr 5 semi syn....5:40..

All cars had a 5:30 from factory and all are in GC so I think having a lightweight oil on startup is beneficial to a start and go lifestyle..though none get pushed hard until oil is warm..the skyline and the ute get worked the hardest so I supply a little extra protection up top..

But when to change, is there a point in a cars lifecycle when you go ok its time to put a thicker oil in it, or should i just keep running what the factory ordered?

lol at how stressed people get over their oils.

a lot of you guys worry to much, i havent seen many engines die from the wrong "grade" of oil being used. Its oil starvation thatll do it!

90% of workshops just stock a generic brand 15/40 because thats all 90% of cars need, including your average skyline.

I recommend changing to something thicker when you start to experience issues with the engine, like blowing smoke or noisy bearings etc. If you want a rule of thumb interval, probably around 150,000-200,000km would be a good time to switch to something like 15w50...all depends on the condition of your engine though. Personally I like to run the thinnest oil that doesn't get burned up / blow smoke...10w40 is still fine for me.

i did try a 10/40 in the honda thinking its old, but it wasn't as nice, went back to 5/30 and its all nice again

@ 155,000 clicks it is in very good conditon for its age though :D

Measure the oil when you drain it, if a significant amount is missing (burnt) then go up a grade eg 15-50 like mentioned.

thats sounds about right, but none of them burn any oil at all :D

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • 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.
