Engine oil level
#21
#22
I have found my car's oil reading to be surprisingly affected by any angle or slope in the road where the car is parked, versus a correct reading on a completely flat road. If the road slopes even slightly I find the dipstick reading will under or over read, depending which way the car is pointing.

I have the same manual for my XJ. Love the part where it says 'M' line. Good luck finding it on the dipstick.
I find the best way to compare oil levels from week to week is to check it with a warmed up engine about a minute after shut down.
There has been some comments on the oil filter non-return valve. I believe the OEM oil filter HAS a non-return valve but do all aftermarket filters have them?? This can change the oil level albeit only slightly.
