    Noticed my oil pressure gauge go from just under half to about 3/4 when accelerating. Is this normal? If not what could be the cause?

    Oil pressure sensor/oil filter bypass? I know my oil pressure will go up a little when accelerating which makes sense. Could try monitoring with a oil pressure gauge to check pressure levels at idle and work your way up in RPMs.

    Ok that's a relief. Checked with the Tundra community, confirmed its a non issue and now ready to go have some fun.

    My mark is just a tad below the half mark on start up and goes just a tad over when accelerating. Toyota tech @LOTSOFTOYS did my oil change.

    This would have been a good question to post ask the Toyota mechanic ;)

    better to have too much than too little! When you gas it and it drops... that's the time to panic

    TOTALLY NORMAL

    Higher pressure indicated at higher RPM = good thing

    Lower pressure indicated at low RPM = good thing

    Its all a very good thing ;)

    If it drops to zero when your driving thats a very bad thing :(

    Had that happen in an Forest Service single engine airplane that I was flying once, not a good feeling at all.

    I immediately pulled the throttle to ided and glided 23 miles and made it to an airport. The right side and the bottom of the airplane looked like what the Exxon Valdez must have looked like, oil EVERYWHERE after I landed. Someone had tried welding up the oil cooler and their welding skills were not all that great. :( When I pulled the dip stick the next morning the engine still had 3 of the 6 quarts of oil left in it (good thing).

    If I had left the power in it would have blown all of the oil out of it and toasted the engine. Changed the oil cooler, topped it back off with oil, cleaned up one heck of mess, and flew it back to my base. No damage at all to the motor.
