What is the consensus on prefilling the oil filter? I've looking around for an answer and haven't found anything definitive.
Why bother!What is the consensus on prefilling the oil filter? I've looking around for an answer and haven't found anything definitive.
I really dont have the space in my driveway to do a oil change safely
Definately fill! You are basically starting and running the engine "dry" for the time it takes to fill the filter! Purpose is to get oil into the engine and build pressure asap. For horizontal/angle mounts, put in as much as you can.Why bother!
Most filters are at an angle if not horizontal, so filling it only makes a mess unless of course you are only partially filling yours, defeating the purpose.... which there is none! You are only saving a step anyway by doing that. I just fill till it is full on the dip stick then crank the engine for a few minutes, shut it off for a few more and then top it off!
Errrrrr...that's not actually true...... There is a film of oil left on all the mating surfaces which seperates the metallic components and as long as you don't rag the engine before the oil pressure light goes out, you won't be making much of a difference WRT engine wear. However, this being said, with filters that were almost vertical, I always filled the filter before fitment - from the outer holes, of course. And, with an engine in good condition, the difference between and filled filter and non-filled filter, the difference in the oil pressure light going out was a second or two.Definately fill!

I've heard that excuse before...... :smoke:Is it just me or does the filter seem to take more oil to fill than it should? It takes damn near a whole quart, it doesn't seem that big just looking at it. :nervous s
It's bigger than it looks. Really, it is.
That's why when I filled mine, I tipped it into the outer holes and let the oil leech into the centre cavity.I used to pre-fill, but stopped doing it. I'll explain.
Advantage to Pre-Filling --> Less motor operation while in "dry" mode. In other words on the initial start up after an oil change, the cam and lifters are lubed "faster". I put faster in quotes, because I believe the time it takes for oil to circulate from the pump to a lifter is a matter of seconds (maybe even a fraction of a second).
Disadvantage to Pre-Filling --> You must have a lot of faith in the oil blender's filtration process at the blending plant because the oil you're dumping into the filter is being dumped on the clean side of the filter. Knowing my luck, I'd buy a bad batch of oil and dump shavings into my filter without noticing.
Just my two cent. Take it as you will.
