I gotta '05 xB and was wondering what the normal operating oil pressure range is. the owners paperwork is vague and I've read some conflcting posts.

I tried to search it, but, well I'm in my 30's now and life is too short.

okay, let's try this...

anyone running an oil pressure gauge - what are you consistantly reading?

DolphinV8

you have any engine mod?

Why would that matter for oil pressure? You are still going to run the same pressure unless you go with a high volume oil pump.....

come on - someone...

peterbilt, I just installed gauges in my xb and the oil pressure is running over 100psi at startup. As soon as it warms up to 180 or so it will drop to 90 or so. At idle warmed up it will drop to 25 to 30 lbs. I am running the Amsoil 10w30 synthetic .
I checked the manual on this forum and it states that the normal pressure is 55 to 80 OR HIGHER at normal temp and 3000 rpm.
Because of these factors I have ordered a new gauge that goes to 150 psi.
In my younger days I would have been very concerned with oil pressure that high, but when you look at the design of this engine it really does not surprise me.
Hope this helps.

newtmaker-

thanks, it does help. the "normal pressure is 55 to 80 OR HIGHER" is what was getting me. I'm getting gauges and will be getting the 150 psi also.

thanks again.

I was considering putting in an oil pressure gauge also. I've been checking online and haven't found any oil press. gauges that go up to 150 psi that are electrical. They all seem to be mechanical.

Anyone know of any 150 psi electrical gauges?

Newtmaker

Do a Google search for VDO Gauges. There is a place in Lancing, MI, Don's Auto Shop or something like that. The VDO gauges go up to 150 and are electric. Good prices as well.

This is at just off idle and warmed up.

Where did you guys attach your oil pressure sender?

Try egauges.com for VDO gauges, they have a good selection of electrical gauges and pretty good prices. I am buying from them soon.

Hey Newtmaker,

Did your oil pressure gauge come with the big sender and if I remember you used the AC Autotechnic adapter at the oil filter mount and did it have enough room?



Thanks

Yes, it came with the big sender and there is plenty of room. The adapter has 4 tapped holes with plugs and depending on what type sender or adapter you wanted to plug in, I guess you could use all four. Just can't imagine what you would use beyond temp and pressure!!
You will need a 1 1/16 deep socket to screw in the oil filter fitting that hold the adapter in place of the oil filter. At that time you decide what angle/position to have the adapter. It's a little tricky holding the adapter while tightening the fitting because it wants to turn also.

I just put in a mech oil pres ga in my xb and at idle it at about 20# and at 50 mi it at 80# so far at warm up.
