1207150 2011-06-06 00:51:00 On my Honda Rafaga I have to use a socket type filter wrench and basically do it by touch as it is in such an awkward spot and can't help but get oil over the engine as it comes out sideways. Always leave it parked on the road after first run so it doesn't drip on the concrete.
In the cycle lane only please ;)

1207151 2011-06-06 01:25:00 Apart from the barked knuckles trying to get the oil filter off/out, the biggest problem is getting rid of the waste product....

Haven't you people in the North shore got handy storm water drains?

Don't worry around here they don't seem to like using the cycle lanes anyway.:groan:

1207153 2011-06-06 07:30:00 I have heard of piercing a filter with a screwdriver in order to get more torque on it... but best left as a last resort.

I HAVE to use the screwdriver to get mine off. Nothing will get up in there to go over it and be able to turn. And you don't have to completely pierce it, just tap it in enough with a hammer on an angle, then tap the screwdriver till it turns.

I never pay to have my oil done - funny how places like oil changes can still charge $60 for 10 minutes work even if you supply the filter and oil. Then they rant about how you're not using the right oil etc etc. I think I may know a little more about what the right oil for MY car is.

People do go on about oil specifications it gets pretty boring. It all comes out of the ground and the piston engine of 1895 is pretty well the same as the 2011 engine. Got a crankshaft, camshaft, valves, flywheel, pistons and spark plugs.
In Bouganville during the war with PNG the locals run their diesel trucks on coconut oil in the tank and in the sump.
It is a job that can turn dog, I was removing a filter on a Honda Civic with a strap spanner the filter just twisted itself to bits and couldnt get the threaded bit out of the block. Had to undo an engine mount and lift the engine up a bit to get access to the threaded bit with a big homemade ezi out.
My waste oil gets picked up by some dude who uses it to heat NZs biggest greenhouses in Woodhill.

Would one of these work for you. See image.

1207156 2011-06-06 08:18:00 I doubt if there is a car with an oil filter that one of these will not fit in the space available:

www.google.co.nz

I have used a wrench for many years that is made from webbing attached to a square section aluminium tube. It will fit in the smallest space, there just needs to be a gap that will allow the thickness of the webbing to pass over the end of the filter. The square section tube is turned with a spanner.

The hexagon socket type are good if there is enough space.

I generally use the largest filter that will fit in the space available, rather than the ones specified for the vehicle make, to get the largest area of filter media.

1207157 2011-06-06 09:30:00 You gotta be careful about fitting the right filter. Just cos it's big doesn't mean it's right. You've got flow rate to think about as well. If you starve the engine of oil, it's curtains. If you buy a known brand name such as Ryco or Fram you've got no problems providing you fit the correct filter. Fram do one specifically for the VW with the impossible to get at filter. You can't remove or fit the filter unless you get the one with a hexagonal head built into the filter top. You've got to get it tight enough to seal too. Doing it up finger tight is great for the workshop who's going to replace your engine after all the oils pumped out on the road.
Prefects idea of running the car into the ground was something my brother in law in the UK did. He worked out the depreciation rate & how may years it took to get down to a book value low enough to write it off & did exactly that. He bought a new car every 5 or 6 years & did absolutely nothing in the way of maintenance unless it was dangerous. He bought Jappas as Eurojunk dies very quickly unless you empty your wallet at it every service lol

1207158 2011-06-06 10:11:00 You would think after 110 years plus of manufacturing automobiles the bastards would always put the oil filter where it could be easily changed. Even some jap 4wd diesels have them in a pig of a place. Like my dumb korean kia sportage I once had where the oil filter was horizontal and the oil made a mess down thru the engine when you unscrewed it. Also for a 2 litre engine it had a bloody small filter smaller than a V can.
I think the poms in the 60s had it sussed with the bowl and cartridge filters which stuck out the side. They were easy to service but sometimes hard to change the square section bowl seal.

I'm not sure I follow your reasoning, if you mean the time it takes to fill an empty filter and for the oil light to come on, then yes, a bigger filter can will take slightly longer to fill than a smaller cannister, meaning bearings are without pressure feed for a slightly longer time.

If one is worried about that, then the filter could be partially pre-filled.

Unless things have changed radically since I used to work in hydraulics and filtration, then car filters generally have a nominal rating of around 25 to 35 micron.

Some will be better made than others, some poorly made ones may leak around the bypass valve, and the filter media may be of poorer quality, all you can do is to buy well known brands and hope for the best.

All things being equal the bigger the filter area the longer it will last, a bigger area certainly will not cause reduced flow.

However, 30 micron is way bigger than minimum oil film thicknesses in bearings, and car filters don't really remove much of the fine particles that can cause wear. A magnetic drain plug is a good thing.

A filter rated at an absolute level corresponding to minimum oil film thickness, say 1 micron or less, would block up in very short order.

My old A40 Somerset didn't filter the main oil flow, it had a bypass filter which just filtered a small proportion of the flow and returned it to the sump, whilst my Ariel Square Four just had a coarse wire mesh strainer :)
