A good thing to do and remember is when changing your oil and oil filter is to fill the oil filter up when putting it in. This prevents engine wear on startup.

 

hmmm i've never done that before on any egine i have done oil changes on. i'll give it a shot cause i gotta do another oil change asap

 

Good Idea! Don't think it will work on oil filters that are mounted sideways though....

 

Been doing it for last 3 or 4 years. On those in my Aerostar and F 150 that are tilted side ways I fill them up 3/4 full. I figure it helps.

 

I have always filled oil filters. On filters mounted sideways, I fill half way and then disconnect coil wire while operating starter for about 5 - 10 seconds to fill completely

 

a little trick I do and it only works when you have room.
is to take a punch and a hammer and punch a hole inthe old filter to drain the oil out first. then it dosen't get all over your hands when you un screw it. but then I do this on the diesel filters. wjich hold a lot more.

 

Thats a good idea Wolf

 

Hey,

I also "flush" a small amount of new oil through the system to flush out any junk at the bottom of the pan before putting the plug back in.

Probably doesn't really do anything, but makes me feel better.

A quart or so of kerosene works great as a flush!

Any time I had an engine "down" (not running) for more than a hour or so during an oil change I fill my oil filter with oil. You can if the angle of placement allows :-) This reduces the dry start syndrome. I don't bother if the engine oil system has been pressurized and still has a lot of oil up in the galleries.

I just use the one hour figure as a good round number, besides I can't remember much longer than that. I may already have that Alzheimer's Mil1ion talks about.

over!

I also park my truck slightley up hill so to drain the oil out of the oil cooler.

 

You are right about that, however pour only enough oil in the filter to fill the media with oil. That way no oil will pour out of the filter when you install it and the filter media will not have to soak up oil befor it starts supplying oil to the engine.

Who told you that?

If you drain the oil , replace the filter, and refill the oil in a reasonably timely manner there is plenty of oil left on the metal in the engine to prevent "wear at startup".

You are wasting your time and effort filling the oil filter before installation during a routine oil change.

 

When I was taught how to do an oil change I was told " always fill the filter before you install it" The old guy never told me why, just said to do it. BTW he was in the Army motor pool for 27 years before retiring. Who am I to argue ??? It doesn't take but a few seconds and if it helps then its a good thing. It sure can't hurt.

 

Well, I have been rebuilding engines and transmissions a lot more than 27 years, and I still say it is a waste of time and effort; however, if it makes you feel good, go ahead and do it. I won't get upset about it. We all have our own way of finding our comfort level with the way we do things. Stay happy. Don't worry.

 

There may not be a way to tell. A Pro, like some that have posted here, may say it is not necessary. Or more likely he doesn't see any return on the extra time it might take him to do it so he does not. That is one of the great things about doing things that you can for yourself. The return may be small but you have the time to do it and in most cases don't mind doing something just a little more time consuming than they would in a shop. However, the principals that allow an induced wedge of oil to support a turning shaft have been studied. The hydrodynamic principal is based on the qualification that there is a constant source of oil to start the oil wedge, there is a angle of metal to metal surface contact during the first 30 or so degrees of shaft turning. Probably, by the time the shaft turns more than 30 degrees the oil supply is flowing. Oil pressure from the pump does not support the shaft it only supplies a lubricant source the wedge is self supporting as long as it has that source. Therefore, it is more likely that an engine that is started and stopped more often for any reason will have more wear than one that is started and allowed to run. As long as the engine had an oil supply to the pump the dry filter start should not be any more damaging than any other start. Wear and failure are more about net cycles than anything else. Sorry, I get to wandering. Does anyone know what the Ford official opinion is on pre-filling oil fiters?
