Ive had my lorry almost a year and seem to remember the oil pressure gauge sticking around 70. I noticed the other week it dropping to 40/45 and have been told thats normal as oil thins when it warms up so asked the mechanic to take a look whilst he did pre MOT checks and it does have a teeny as in teeny teeny oil leak from the crankshaft seal. The dip stick level has not budged. Drove it today and when idling it went lower, to about 35, Im getting paranoid and obsessed now!! So just wondered if you could please have a look at what your dial does (figure wise) from start up to end of journey please as it may well be normal and Im having a flap for nothing lol. Many thanks in advance!
