Hi guys, ive searched around these areas but i cannot find a straight answer for which engine oil i should run in my RB25DE Skyline.

The car will be used on the street/daily and wont see the track (atleast for a while).

depends on how much you want to spend. all you really need though is a 10w 30 semi synthetic oil, although you could use a basic mineral oil if you were strapped for cash, but i'd stick with the semi. if you want to go all out you could go a full synthetic, but to be honest, for a natro skyline i wouldn't bother. as for brand, that is really personal choice and everyone will have and opinion as to what is good.

you could have a read through this thread for some opinions

Any of the nulon range are good.

LOL^

I use penrite mineral 20 - 50 (60) Extra 10.

serves me well

but don't get their 20 - 60 stuff, i only use that thick cause my engines 33 years old.

Get the next weight range down or 2

Yer im with Dan ive been using a full synth Nulon for the last two oil changes, seems to do the job quite nicely.

But yer in all honestly, and semi/full synthetic oil will be fine as Mark stated.

yer like dan said, any of the nulon stuff is not to bad. I use a full synth in my 25de and it seems to be ok i cant remember exact numbers, but in all honesty as mark said before any semi/full synth oil of the right grade will be fine, its really just comes down to what branding u prefer :)

thanks everyone for the help. so i should go ahead and get 10w 30 either fully synth or semi, in the brand of my choice. sounds easy enough :)

10W30 recomended for RB25DE, i go with Valvoline Synpowers for my last service found it quite good and after 5-6 months still has the rich honey like color to it after 2300km of driving. However never 100% impressed im going to try Royal Purple, a friend with a S15 uses it and recomends it for japs cars so ill give it a go.

I Use mobil1 5w 50 .... planning to change on something else after the 100k service though

I only change every 6 months as well ... thats generally only about 5-6 thousand kms as well, i dont drive the skyline all that much .. its still very clean at the end of every oil change so i havent seen the need to change it more often

i think the motul stuff has been quite highly recommended as well

we use mobil1 at the moment cos my dads been using it since his good old days

probably going to try something else though maybe a 10w 40 or 10w 30 fully synthetic. i dont really change my oil often enough though, should probably go for something a bit cheaper but still fully synthetic and change it more often .. im paying about 80 bucks for a bottle of oil atm with mobil 1 and ive seen some castrols go for a fair bit less ... or even the motuls were going for a decent price ..

that thread on oils confused the hell out of me lol

I don't recommend nulon, mainly cause of the price. I believe cheap = cheap quality product.

I out nulon in the same basket as el cheapo gulf western.

lol, whilst I agree with you regarding how shit the Nulon oils are, Gulf Western's Sougi S6000 was every bit as good as Motul 300v (Group V Ester base stocks)... $60 for 5L too!

Just a damn shame they aren't making it anymore :(

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
