A little fun in the title to kick off an interesting topic. And that is -
Synthetic vs. Normal mineral based oils. A few folks have chimed in from the oil temp thread, but good to keep the info ordered so a new thread was started here.
Some of the reasons that I run synthetic is for potential lower oil operating temps, as well as its ability to withstand more abuse then mineral based due to its elevated temperature capabilities and a much higher load capability acording to the marketing fluf that is floating around on the web. Ton's of good info, but nothing like peoples first hand stories to give some info.
I don't have much scientific to offer except that I am running Royal Purple racing 41 in the 65 Mustang (331cu" 12:1/Solid roller 560+hp@7200). I don't run an oil temp gauge, and I guess wouldn't look at it until the motor stopped working anyway, but I guess that temp in the pan would be a good indication point of how well it may be working vs conventional oils. I have not had the motor apart for anything since I started using the synthetic so can't say how things look. It usually runs in the hot desert climates of willow springs. The broken rocker shaft was before synthetic as well, and on oil changes the oil generall looked cleaner then the conventional counter part.
Another good questions is about brands and why?
I'm running Royal Purple as it is pretty easy to get in the conventional viscosity I used to run (or close to it). Also easy to get via mail order, like AMS, and others I'm guessing. I'm not comfortable running a lower viscosity (or would likely run mobil 1), although some say that this is where you can get some free hp (Nothing is in fact free as far as I can tell) due to less drag.
Have at it!
