Hey guys. Decided to do my own oil changes now, which I don't know why I wouldn't have decided to do it sooner with everything else that I have tackled myself with the XJ.
Anyway, last time my oil was changed at the typical quick lube place, Pennzoil was used, pretty sure I had them put in 5W30 as winter was approaching. They used a M3600 Engine Guard II filter.
Before I changed the oil my pressure was around 40-60 accelerating and 20-40 idling IIRC.
Today I changed the oil, figured Castrol High Milage 10W30 would be fine since my '98 has 196k on the ticker. I used a Fram Tough Guard TG-16 filter. I noticed the Fram filter is larger in diameter than the old Engine Guard II filter.
Now on to my question: with the previous oil/filter used and the new oil/filter installed should one expect a 10lb.+ drop in oil pressure? I am experiencing less pressure than I had before. I wonder if that is due to the filter being larger, or to the new weight oil. I do not see any leaks anywhere.
One other thing I noticed is that the oil cap on the engine seemed to just spin around and not positively stop as if it was fully seated when I put it back on. I have had the cap off before and never remember it being like that when I put it back on. Is that normal for the cap?
Any ideas? Thanks guys.
