disconnect battery when changing oil?

somehow I missed something in MadXJ's page about synthetic oil filter size comparisons. He mentioned about shorting the starter solenoid when changing the huge Mobil1 301 oil filter... can anyone shed any light on that? How can an oil filter short out something else when the filter itself is not electrical in someway? I just changed my Mobil1 filter and it didn't short... or maybe I am just lucky.

here is the link, (the statement near the top of the page is highlighted in red): http://www.madxj.com/MADXJ/technical...Conversion.htm

....when you drop your wrench on it....the filter(adapter/mount) is just above the starter.

Yes it can happen.The shop where I helped out this summer had a 5 spd run into the pit when the filter can shorted the starter.I wasn,t there at the time---
The terminals on the starter are suppota have a rubber cover but age and repair will remove them.
Be careful out there------

ok thanks, so to reiterate... never put wrenches or anything metallic on battery posts and two... put some kind of non conductive layer between the starter and oil filter or just be extra careful not to touch starter with the bigger oil filter.

please correct me if I am wrong or anything else I might have missed. I like the Mobil1 301 filter for bigger heat dissapation and extra fluid capacity and filtering capability.

I have a í91 with the 204-style oil filter in the vertical position. Iíve never tried it, but it looks like there is plenty of room to put in the larger 301-style filter. I can easily reach in and touch the top of the filter with no obstructions. I understand converting to the standard thread, but why would you want a horizontal mounted filter? There is much more room with the vertical mount.

mine came as horizontal... stock. I wish it was vertical, so I don't spill oil when I drain it. I suppose it gives us more clearance when we go offroadin

other than more oil capacity and usage, what does a larger oil filter do?

larger surface area for filtration and cooling kinda like an air filter... bigger surface area for more filtration and breathes easier
