new oil change new problem

[lilpiton]

Ok so i did my oil change i put in 1/2 a bottle of lukas and mobil 10w 40 non syntatic and my oil press seems low! and idle its as low as 13psi and on the highway at 3000rpm its like 33psi, is that right, is that saff??

You need thinner oilr your pump is having a hard time pumping that 10-40 through there. Try 5-50 or 0-50. the first number is what your engine pumps the oil at wehne you start it. The second number is what it runs at constant. and if your running a turbo you should deff run synthetic try 20w50 0r mobile 0-w50.

Ill try that but its kinda weirg cause my boy has the same kind of motor and when his car was running the oil press was good with the same 10w 40 I will give that i try, thats what i was thinking of doing too.

i didnt understand anything you just said.

he was saying that he has the same car as his dude and his runs fine on 10w40. but he was actually thinking of trying my suggestion. also remember cars are like people just cause your weed gets you high doesn't mean it's gonna get me high. if you catch my drift....no pun intended.

lol sorry was in a hurry.Im buddy has the same kind of motor in his car and before the winter that it was still running hes oil pess was 26psi at idle and mine is like 13psi and we both osing the same kind oil oil.I guess i will try running thinner oil.p.s i rebuild the sr about 9 munths ago and before the rebuild the oil pressure was good as far as i remember.Any suggestions would really help me out guys thanks...

Your pressure should actually be higher from a weightier oil...

Your pump may be failing. I wouldn't drive it until you inspect it further. There is definitely something wrong.

Why did you put in lucas?

Ding ding ding ding ding!

Motor oils don't need anymore additives.

I put in the lukas cause with out it my vvt is loud as hell. i was thinking that maybe the gauge is showing wrong! What psi you guys have at idle and 5th gear at 3000rpm?

I did think that the pressure should of been higher with weighter oil but then i thought that lighter oil has easter pass and should build pressure faster? When i rebuild the motor and up the oil in and started driving it the press was like 17 pis at idle then once the oil got older the oil pressure was around 25 at idle and around 60psi when reved to 3000rpm.

lol.

My KA oil pressure at idle is 4.

Don't feel so bad.

Pressure should build immediately after startup, regardless of the oil weight.

If you're starting your motor with cold oil, you should get about 70-80 psi of oil pressure right away. The oil is much thicker when it's cold.

When you're all warmed up, 25-30 psi at idle and 60psi at 3000 rpm doesn't sound bad at all.

Sounds like your pump is on its way out. Inspect it before you drive or start the motor.

4 bar or 4psi??? If it's the latter...

When i start it cold I do get like 75psi. but at idle its like 13psi!how can i inspect the pump and how will I know if its going bad??When i was putting the motor back together i checked the pump it seemd fine unless theres a special way to check oil pumps??

How can i inspect the pump?
