XJ Ask the Question Thread
When I bought my 98 xj the oil psi gauge read 30psi while driving but dropped to 10psi at idle. I changed the oil twice over the course of 1000 miles and it helped with the psi, however when I changed the oil psi sending unit it seemed to do the tricks since while driving it read 45psi then dropped to 25-30psi at idle. Everything was good until today I noticed that after it warmed up it was only reading 30psi driving and if I switched it over to neutral to slow down it would drop really low, almost under the 10psi mark. Does it sound like the sending unit is messed up?

So, if I have a stock XJ for winter commuting (0% trail use), then I should just stick with 225's instead of 235's. It looks cool to have a "beefier" tire at 235, but in reality, there is no benefit for larger/wider tires for a road car.
