Another tough OC.
2011 Nissan Sentra 2.0 S
113255 miles on MR20DE engine.
Out: SuperTech Mix (5w20 Full Syth SN, and 5w30 High Mileage Full Synth SP).
In: SuperTech 5w30 High Mileage Full Synth SP (and < 1qt of fresh left over mix listed above) whatever comes out to 4.12 qts or 3.9L, which is what the Owner Manual states, but is always beyond the H mark on the dipstick, which makes it hard to tell if any oil is getting "used" because when I check it over time, it seems to still be above the H mark, whether checked hot or cold.
Off: AC Delco PF1237 Oil filter
On: AC Delco PF1237
I guess I forgot how to change oil, or I don't know anymore, or I'm not doing something properly.
This is the 2nd oil change where I have had extreme difficulty in removing the oil filter.
The first oil change I ever did on this car was in May 2020 (I got the car August 2019, and I'm not sure when the oil was last changed prior, so the oil could have been in about a year). The ACDleco PF1237 filter came off no problem with the strap/band filter wrench, which was probably a little bigger than the filter. I installed a Denso 150-2002 filter.
The next OC, the Denso filter came off, no problem, again with the strap/band filter wrench. It was replaced with a Fram TG6607 filter.
Ok, so 3rd change, and the Fram TG just would not budge. The strap/band wrench just would not grip, it kept slipping, and it seems it is now bent out of shape, and the rivets/welds where the strap comes together (I don't know how to describe precisely, but you get the picture), seem to be not as strong. I had a heck of a time, and finally, a pair of large ChannelLock/water pump pliers worked, and the poor TG6607 filter became mangled beyond recognition as a result. It was replaced with an ACDelco PF1237 filter.
So, now, this most recent change. Again, I could not get the darn filter to loosen. My set of oil filter wrenches/pliers (the kind with "shark" teeth, lol) I purchased, just didn't want to grip. I purchased two different wrenches, and they just scrape the paint off. So, I had to use the water pump pliers again (which have no teeth, and don't grip well, either, but I can crush the filter which allows a better grip to be had) and the filter again became mangled. But before I could use the water pump pliers, I could not get good enough purchase, so I had unclamp one end of the the coolant hose, and it puked coolant into my oil catch pan. I was finally able to get the filter off. I replaced the filter and reconnected the coolant hose, and refilled the oil and coolant. I have not had to disconnect one end of the coolant hose the previous 3 times doing OCs on this car, so why now this time?
So, why are these last two oil filters so difficult to remove? I do not use a wrench to tighten the filters; I just spin them on until I can't turn any more. I also give a good smear of fresh new oil on the o-ring (except for the Desno, which was pre-oiled). I don't recall if I put oil on threads, but I generally do. I have used my MityVac 07400 fluid extractor for every oil change going back a couple vehicles, and never encountered this issue. Is it possible the vacuum created by the MityVac is sucking these filters on tighter? What am I doing incorrectly? It's not like these last 2 filters were on for an extremely long time.
I just can't figure out what I've been doing wrong. These last 2 changes, I didn't warm up the engine, so I extracted the oil "cold", but outside air temp today was around 80°. Could that be it?
I certainly do not want to drain nearly a gallon of coolant out again any time soon, so what am I not doing right? Although, since I don't know when or even if coolant was changed out, it has about a gallon of fresh Peak OEM Asian Blue, mixed in with whatever was left, so that's at least an upside.
