hey guys, heres the problem, today i did a oil change, i went from running crapy normel 10w30 oil to Royal Purple 10w30, the problem is that before i did the oil change my oil pressure was about 300 but now with the new oil its 200 but most of the time its about 0 to 50. now i also i used gunk engine flush to. i know i did everything right, but i need some ideas, thanks guys

300 PSI?!? thats way to much pressure. Ok you changed oil, Did you go to just standard royal purple or fully synthetic? Synthetics have been known to cause lower oil pressure on some applications due to parts being worn and the oil is more slipprey. The nice thing about synthetics on high performance is they well produce better oil pressure when hot cause they are a more stable oil. At least according to what the oil manufacturers told me at the last seminar that I went to.

its full synthetic, i not sure about my guage, all i know is when i start the car it shows 300 but when the motor warms up my oil presser go's to crap. when im stoped at a light or something it shows 0. could it be the oil presser sending unit going bad when the car starts to warm up?

Do yyou mean 30?????

Because if u have 300 you have either a VERY extreme oil pump or your sender is just ****ed up lol

Either that or theres something wrong with the system...

Try hooking up a mechanical oil pressure gauge, they seem to be damned accurate and that will tell you exactly whats going on

my guage is a stock camaro guage. it go like 0-100-200-300-400

eh..... Maybe an overseas model? Reading in Kpa or something... Stock gauges go from 0-60 psi or 0-80 for the v6.

I live in Canada, and our gauges read in Kpa, that is what you have it sounds like. 200 kpa is about 30 PSI, 300 Kpa is about 45 PSI.
