Hey guys,
I'm not too knowledgeable on oils but i have been using penrite 10-70 in my 98 R34 GT-T, its been good but the oil temps get a bit higher than I'd like with little effort (just normal driving sees temps around 100-105°c quite regularly). I just switched to Nulon 10-40 thinking that the penrite wasn't draining to the sump easily enough but it doesn't seem to have brought the oil temp down.
My water temp is aways good as i upgraded the radiator and added a twin fan set up.
Im just wondering if anyone has any advise the can give me, or if both my choices for oil are wrong.
Maybe its the symptom of another issue?
Any help would be appreciated.
Thanks guys
-Jimmy
