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.

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

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

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
