I drove a 1994 tonight and the oil pressure seems a little low to me. It has 61,000 miles running Mobile 1 and it ran in the low 40's. Is this normal?

Also is there anything else I should be looking for in a 94?

With your foot on the gas, it should be in the mid 50s at least.
At full throttle, 60 or better.

Idling it should drop into the 30s.

Keep in mind that oil temperature has a big impact on your oil pressure. My '95 with 40k miles when hot (long highway run) runs around 40-45 at 70mph. Idle hot between 25 and 35.

When cold it's up over 60 all the time.

Mobile 1 5w30.

Thats fine, you don't need 60lbs at idle. The faster the pump turns the higher the pressure. 30 lbs is good at idle.

I've heard that as long as you have some kind of pressure, it's fine. Pressure changes in line with a lot of other factors: temp, eng speed, idle..etc.

High oil pressures cost you horsepower. GM put the operational range for the LT-1 at between 20-80 lbs. It varies with the combination of oil level, temperature, oil thickness, rpm, moon phase, etc.

Any reading above the shaded mark on the guage is considered "normal".

More is not always better...
