Default Re: '02 Ranger jittery oil gauge

I've noticed the same thing with my 03 auto 3.0
It only seems to do it when its very hot out and I have been on the highway for an extended amount of time. It seems to be worse when I have been towing i.e. O/D off (higher sustained rpms)
I pretty much came to the conclusion that due to the sustained high rpms and the light oil weight (5w20) that the engine was frothing up the oil and at idle it was pulling in the bubbles and that was the reason for the "jitters". My solution was to switch to a heavier oil during the summer months (10w30) and back to the regular oil when it gets cold again. Seems to have effectively solved my jitters.
