17 psi is pretty damn low. I idle between 30 and 32 psi. After some hard driving it may drop to 29 psi but thats it. There was one time I didnt change my oil for 4K and I still idled at 30 psi. However at throttle pressure was a bit lower that with new filter and oil. At wot I see 60 psi easy. Normal acceleration I get up to 40 psi. Not saying its the oil that your using but may be something else. Just a heads up.mikesgtoinvegas said:i just switched from the m1 to royal purple 10w40. so far here the heat my oil pressure stays up at idle, when hot it would be about 17 psi at idle. with rp it is about 24 psi.
Please tell me where to find this German stuff.. Everywhere I go they don't have it.. I went to napa once and they had Amsoil 0-40 but only 4 bottles..GMH GTO said:German Castrol has more Zinc Phosphours, ZDDP and Zoil then most off the shelf oil. Run it in my families fleet, 7500 mile intervals.
Whats not to like about synthetics? Some people have a fasination for mineral based oil however quite a few "synthetics" use mineral oil basestocks, mineral oil in the next API rating SM (?) will be a Group II oil minimum, just a few additives short of being a considered a synthetic.
