Hello, all...
I'm new to the 914 scene, but have been having a blast reading up on all of the information that is available here at 914world! I just got my 914 about six weeks ago (details in my signature), and have been able to get answers to a bunch of my questions by pounding on the search button. But here is one that I haven't been able to figure out on my own. The car is currently running on Brad Penn 20W50 oil, which is highly recommended by Jake Raby and others. Here on the Front Range in Colorado, as the weather has started getting a lot cooler, I've noticed that my oil pressures are quite a bit higher than in warmer conditions. Specifically, with ambient temperatures between 30 and 40 deg, I'm getting better than 120 psi oil pressure at 2500-3000 rpm after running for several minutes. As the oil warms (15 minute commute), it drops to a bit below 100 psi at the same revs. I've got a very efficient front mounted oil cooler, and my oil temperatures rarely get to much more than 200 deg in warm weather, and was maybe 120 deg this morning at the end of my commute. In hot weather, my pressure is just a bit more than 20 psi at idle after extended running, but better than 40 psi after my commute this morning. Couple of questions: 1. Are my hot weather oil pressures somewhat normal? 2. Are my cooler weather oil pressures too high? 3. Should I switch to the Brad Penn 10W40 now that the weather is cooler? Go easy on me, I'm a noob... (IMG:style_emoticons/default/smile.gif) |

Just to do a quick test wrap the oil cooler with some thick paper and just use twist ties so you can take it off real easy. Monitor your oil temps/pressure while you go for a drive and see what your results are, DON'T LET IT GET TOO HOT. I've seen thermostactically controlled oil coolers for sale, google peformance products and see if they have them. Bottom line, whatever Jake says to do you should do. Switching to Brad Penn 10 W 40 won't hurt but if Jake overules that then listen to him, I do.
