I put some 10-50 in a month ago. I hated it, oil pressure stayed at 100psi for 5 min on cold start (this is in summer). Once warm if I give it a bit of stick I reached 100psi at 4000rpm. Car felt so sluggish, and cold start noise was much more prominent.
Dropped the oil and put old faithful 5-40 in. Oil pressure nice and normal and cold start noises gone.
It all comes down to the life the motor has had I reckon
If they are anything like my achilles atr sports, give them 10,000km and they will start to turn to rubbish. I still have shit loads of tread but they just dont want to play the game anymore.
Federal RSR's for me in a 2 weeks
Bro, I told you, its nothing to worry about. With the weather we have been having in the past 4 weeks, my car has started first time, every time in the morning
As per my service manual, and the fact that when I put it into rwd, I look on the torque transfer gauge and confirm no torque is being transferred.
Besides, The MANUAL says that you do this when towing the car with 2 wheels in the air.
He asked for tyre sizes.
265 you will have no problems with, 285/295 i do believe you will have scrubbing on full lock. Theres a couple of threads kicking around, some guy put on 295's couldnt turn full lock, went to 285's and was happy
