[Line 3]

thanks

[natho33]

am also interested to know, might give my car a service on the weekend and am interested to know peoples choice of oils.

castrol edge 10W 60 with 600ml of oil stabiliser

[Reggi34dr]

castrol edge 5w30, as thats one of the weights listed in the manual.

[666DAN]

I used Penzoil semi-synth in the 25GT, 10W-40 did just fine for 110,000Km I put on it

[N-DAWG]

As per my tuner's recommendation, Castrol Edge 10W60, and that's with a turbocharger bolted on. I think as Dan said 10W40 will do the a good job on a N/A

[central coast person]

redline 10w-40, $168 for 3.8ltr

i would not follow what the manual says as we are in Australia and not japan so the oil preforms differently. You will need a thicker oil than 5w-30 because you will get unwanted engine wear over time. Best weight is 10w-60

the only reason i have 10w-40 in my car is because its only one 453km ...... literally. don't go thinner than this.

[Mr.Massive]

im with the 10W40

[natho33]

ended up servicing the car with MOTUL 4100 turbolight 10w40

cost about 60 or 70 bucks for the 5 liters, car runs heaps better now definatley reccomend this oil for your n/a skyline

[josh_gts]

motul 300v chrono - 10W40

cost me $110 for 4L going to get another 2L tomorrow lol.

but even with 4L in it, it runs 3947464657048 times better, makes a huge difference.

next on the list is the gearbox fluid lol

[central coast person]

redline Lightweight shockproof has probity saved my gearbox. I dont care is cost more than gold my gearbox stopped being clunky and made it feel new again

ended up making every single part in my car that needs oil being redline oil and dont forget the coolant

81 skyline mgc 210 coupe l24e engine 168 000 km on the clock what oil would u reccomend iv been told if i use too thin an oil it may leak out the seals being an old engine but no one will give me a strait answer lol

[MissR34]

Martini Racing 5W50

also there is a group buy happening if your interested

[hr32gts]

The reason for not using a thin oil on an older engine is because of the engine bearings ...

if you use a thinner oil it increases the possibility of you spinning a bearing

just like in a used differential it is unwise to change diff oil with old bearings ... as when you add fresh oil with old bearings they fail

[SKYL1N]

Amsoil 10w-40

[mgc210 dude]

Martini Racing 5W50

also there is a group buy happening if your interested

where when n how much do i need to buy

i been told to use penrite hpr 15 but im gona flush it with crappy gtx first

[mgc210 dude]

whats every ones thoughts on using penrite hpr 15 0nce i flush my oil? also iv been told if i use the shorter z170 filter instead of the longer z115 (both do fit the z115 is the standard recomendation for a c210 the z170 for the r30) it will boost my oil pressure slightly witch makes sence to me but is this a bad idea in an engine 28 yrs old with almost 170 000 km on the clock? any ideas would be greatly apreciated

[iseekool]

I'm using Castrol GTX 3 15w40 - nothing special and meets specification the stock rb25de actually only requires GTX 2 equivelent, but since I change it so frequently it seems to suffice.
