oil pressure

[rayjak]

Have an 88 Carrera..and have a question about the oil pressure . I have only been driving it for a couple of months, and have noticed a change in the gauge readings. Used to be around the 5 mark cruising on the hwy, and between 2 and 3 at idle. Suddenly it's around the 4 mark hwy, and bouncing around 1 at idle. Lots of oil in it, and may not be an issue...just curious what is "normal"...

[Oh Haha]

Hotter temps can cause lower oil pressure as well as the oil breaking down. What grade and brand of oil are you using?

By "lots of oil", what do you mean? Did you check the oil level correctly?

Rule of thumb is 10 PSI per 1000 RPMs so your does seem to be "normal".

[rayjak]

Am using Brad Penn 20/50 oil level is between the marks on the dipstick, at idle, hot engine. I don't think there is anything wrong, doesn't seem to be anyways. Was just curious why the sudden change. Could be just one of those things...thanks for your response

could be the sender going bad.

[Oh Haha]

Sounds as if you are using the right oil and checking it correctly so I would just watch it for now.

BTW-Is Legendary Motorcars based in Bowmanville? Your city sounds familiar.

OP, what does "bouncing around 1" mean?

Mine is usually a little north of 1 bar at idle and 10 bar per 1000 rpm as mentioned. If it flickers like mad it might be the sender.

I`m no expert (even though I tell my wife that I`m a genius... but can not print her reply) but I ask the same question last year.

The rule of thumb is, 1 bar (10 PSI) mark on the Druk gage (gauge, dial, Lehre, thingny, whats you call it) per 1000 Rpm.

So 1 at idling and 5 at cruising on the highway is fine.

+1 on the Brad Penn 20/50.

You are correct... Nothing wrong

... for the sender being problematic. Usually a cleaning of the connector solve this, ask me why I know that

Not to be picky but you either meant; 1 bar per 1000 rpm or 10 psi per 1000 rpm. Definitely not 10 bar per 1000 rpm.

1 bar does NOT equal 10 psi.

1 Bar = 14.504 PSI.

In my "rush" to answer I did not check my book (1 bar = 14.5037738 pounds per square inch) so I'll publicly eat a piece of crow pie as long as you supply the wine . I should have pickup on that as I used to be a Navy diver

The main point was that 10 bar per 1000 rpm was incorrect, but 2 wrong does not make one right.

Jeez. it was just a typo.

Do not worry unless you are less than 10 psi per 1000 rpm. 1 Bar is considered the target.

Typo plus my mis-quote on the Bar to Psi... Look out she is gonna blow

It's funny there is a lot a misconception when it come to the Druk & Oil Level Gage (I'll spare you all the other name for it).

My PO though if both of them were at the top at any given time it was good...

Not knowing any better, I believed that until after cleaning the connection for both sensor which resulted in normal operation which prom me to ask the usual question.

Druk vary with the RPM and the Oil one is only good when idling on a flat surface.

^^^^LMAO.... we've got a pissing contest going one here. Max, at 6000 RPM that's 60 PIS....better drink a lot of beer. Max is buying

Legendary I believe are in London, Ontario. I could be off a bit, but I know they are nowhere close to me. What is very close is Mosport..legendary ancient F1 track...still in use by all kinds of speed deamons...again, thanks for all the replies...

[brads911sc]

Love the pic!

No harm. No foul. I have made far worse mistakes. Just wanted to correct so the OP wouldnt think his system was off based on PSI numbers...
