What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[R3cord303]

If I remember right, the oil temperature is calculated and not actual. On a hot day mine has been over 200 degrees and it has the factory cooler too!

Might as well calculate oil pressure while we're at it. If it uses oil pressure in that calculation, I'm screwed because of the high pressure pump.

So changing the oil today for the first time with the fumoto plug, damn it takes forever. Still draining after 10 minutes. Oh well, gonna grab some coolant and a bottle of brake fluid to top them off as they are a little low. Not at the minimum yet though. Power steering was full.

So question, and I know the answer I'll get, but I'll ask anyways.

Say we change our oil at 3-5k, but you buy a filter that supposed to last 15k. Those high mileage ones. Has anyone ever just drained the oil and put new in, while leaving the old filter there? I know, for good measure and $10, change the damn filter, but if it's still got mileage to go on it, wouldn't it still be effective?

I have a filter that I'm gonna change it out with, but just wondering why we constantly change the filter if it has more life left in it

I'd rather leave the oil and change the filter myself. If your engine is clean you may be able to get away with it. If you're changing oil at 3-5k its proably because its getting dirty. There was someone on the ford expedition forum I think it was, that was using all synthetic oils, and a deep filter, that was changing the filter every 5,000 miles and adding the quart that was lost in the old filter, and had been doing that for the past 60,000 miles.

Your millage may very. I think if you really wanna find out if you can get 15,000 out of a filter, change the filter this time, and cut the old one open, and see how much stuff its caught. Then next oil change don't change the filter, and cut it open after two changes.

The only time I've not changed the filter was before I went on the cali trip because it was a brand new engine, and I just did a drain and fill, to get fresh oil in it after running the brand new engine for ~300 miles. Doing a fresh oil change tomorrow after the ~3,500 mile road trip. This next service interval will be a full length oil change when the oil life meter says 20%.

I change the filter on Jenn's car every other oil change, so every 10K miles. It's a small car with a 2.0 liter engine that runs efficiently and cleanly. It gets mostly highway use at mid-RPMs and I use top-quality oil, so the oil nor the filter is subjected to anything harsh. I replace the filter on the Tahoe at every oil change (5K miles), but that's because I end up changing it only 1-2 times a year due to the limited use. It also gets driven harder than Jenn's car does. For any vehicle, I use either WIX, K&N, Fram Ultra or Mobil1 filters exclusively, depending on whichever is available and/or cheapest at the time. I trust their build quality is adequate for more than 3-5K mile OCIs. Now, if it was on an engine that was being flushed/de-gunked and the drained oil contained discernible particles or even was just really dirty, I'd replace it every time.

Yes the Fumoto and the Femco drains are slow so I just open it and let it drain while I go have some coffee. And for oil filters, I don’t buy 15,000 mile ones so I don’t have to worry about when to change it. I wouldn’t trust it.

It used to be, long ago, old school, that was kind of the norm. Change oil every 3k, but change filter every other oil change. That is why in the owners manual capacity charts they would show two different quantities of oil, one with filter change and the other without.

Example

Oil capacity:
4 quarts
5 quarts with filter change

When we were broke we would often leave the filter for a few drain and fills. When we were really broke, we just reset the OLM and voila, we were good for another 7,500 miles! Had to reset that a few times too before we actually did anything. That LZ9 motor ran like a top and the oil was always M1 synthetic.

New tires! 305/50/20 Toyo AT2s. Meaty looking on stock wheels. No rubbing and 2.5mm taller than stock 275/55/20 so not really any difference.

I definitely didn't think it would take almost 30 minutes to drain...no big deal

So is there a real quality difference in between a basic Mobil 1 filter and let's say the one that lasts 20k? I usually only use Mobil 1, but tried k and n last time because it had the nut on the bottom. Ended up using the filter wrench anyways.

I also tried the Amazon basics full synthetic oil 5w-30 this go around. Reviews were good and seems like a decent oil. Could be mistaken though

Looks like a good winter tire
