i used the K&N wrench on filter so i can just use a 1" wrech and pop it right off

 

The K&N filters are nice for that, but I dont see the point in spending $13+ on a filter. Sometimes I dont even spend that much on oil! I just like to get the puke yellow Purolator Pure ONEs and Napa Gold filters. Great filter for the money.

 

I dunno where this idea came up that the engine would be starved for oil if you don't fill up the filter. With a properly working oil pump, it should only go a couple of seconds before it's all filled up and running anyway. My reason for not filling an oil filter is that it can become a real mess. Not all vehicles are as easy as our Rams. I have had several cars where you had to either install the filter side ways, reach around some pipe, cross member, motor part or what not which made it really hard to do. I have dropped filter in the process of installing them because they were so hard to get a grip on. Some front wheel drive cars are a real pain to work on.

 

There is nothing like spilling some of the oil out and it running down your arm to at least as far as your elbow. Softens the skin too.
Don't worry about all this stuff in it they say is bad for you, you won't live forever any way.

 

Umm, I think thats the point, those couple of seconds, when the motor is sucking air instead of oil.

I agree though, in some vehicles it is not very feasible.
I doubt if many instant oil change outfits, or even dealers, do it.
I've always done it for mine, seems like the logical thing to do.

 

all this talk about starving the engine without filling the filter got me thinking and though some may say this is a newb ?, Im going to ask it anyway cause I'm curious now.

Whats the "path" (for lack of a better term) of the oil threw the engine??
Does it go:

Pan->Pump->Filter->engine components-> pan
or
Pan->Pump-> engine components->filter-> pan

Hope you can understand that, but the first one is the one that makes the most sense to me but

 

But in reality the engine is not dry anyway. I dunno about anyone else, but when I change my oil, it only takes me a few minutes. I drain it out, take off filter, reinstall filter, refill and run. On a slow day it may take me 10 minutes. The engine is still lined with a good film of oil. It should not really experience any friction or heat build up for those 2 seconds. I don't let my engine drain for an hour or more.

This is the correct path. It is filtered before it enters the engine, not as it's draining. It needs pressure to pass through the filter, but it drains back into the pan through gravity.

 

Reading this thread reminded me of the first time I changed my oil in my first car. A friend and I went to a auto hobby shop to change both of our cars oils (first time doing it for both of us). We knew what to do and everything so it wasn't anything to be unsure of doing but my friend forgot one thing about fluid when he popped the bolt off of his tank...Our cars were on lifts so the oil tanks were roughly...6 feet of the ground...He popped his bolt off, had the tank a little too far forward and the stream of oil caught him dead in the chest. It was classic, I never let him live it down.

 

Thanks Ram15002ndgen thats what i figured but wanted to know for sure

 

the only thing i fill the filter up on is the CAT tractor (and its filter is this big)
