Hello everyone. Did a search and haven't found any definitive answers or the same issue I'm having so I'm asking. Just got the oil changed on a fairly new to me (just got this cruiser about 4 months ago) and right after the change, the oil pressure runs at just a hair below the "H" mark. Since I've had it, its always ran in the middle and would fluctuate based upon revs like most cars. Previous owner kept great records and maintained the vehicle (the thing looks practically new, inside and out) so this vehicle has been taken care of. This was the first time changing the oil since I bought it so I'm a bit perplexed with the situation.
Basically here's the situation:
Took the vehicle to the local quick lube (for ease of oil disposal and time)
Provided an OEM toyota oil filter
They drained the oil and changed the filter and filled it with full synthetic oil (using the correct oil weight and amount)
Like typical, they showed me the dip stick reading at the "full line"
All good.
Left the quick lube, got gas next door and then head home about a mile away. It was during my quick drive home that I noticed the oil pressure gauge climbing and eventually topping out at the "H" mark. Pulling in the drive within 5 mins of leaving and immediately checked the oil..... and just like I was shown at the quick lube, it still read at the full mark on the dip stick. Drove straight back to the quick lube (oil gauge still at H) and they looked over the oil lines for kinks and etc.. Nothing kinked so I had them take off the genuine toyota oil filter they just put on and replace it with one of their aftermarket oil filters (my thinking was that maybe by some random chance the toyota oil filter was defective or clogged or who knows what, but that's all I could think would be wrong). Fired the engine up and once again, slowly creeped up to H. Realizing that it's not the oil filter, I left and drove around a bit and the oil pressure stayed at H. Now I'm back home and at a loss at this point.
Once the engine starts, the gauge jumps to the mid way point fairly quickly like normal. However, once there, it slowly starts to creep up to the "H" mark. It does this slowly over about a minute of run time, maybe less, but the point I'm making is that it's not an instantaneous jump to H, it seems to creep up to it from the mid way mark after start up.
Anyway, thoughts, ideas, similar situations? Any help/ advice is appreciated. Thanks
