hi guys.
its just a silly question but im confuse here. its for my 325i 94 with 135k miles on it. should i put 15-40 syntatic or 15-40 regular engine oil. is it good to put syntatic with these kind of miles?
and one more question does manuel 325i has some kind of transmision oil if so where does it goes. and wat type it should be?

And I would advise you syntethic

Tranny fluid doesn't need to be replaced, it's free of service

doesnt hurt to check auto tranny fluid levels...
i even changed the filter, fluid and used new gaskets
a hose with a tiny slow drip or bad gasket could get the levels low over years

to check or change your tranny fluid the process is a bit like your diff. there are two bolts, one on the bottom for draining, and one on the side for filling and checking. what you do is drain your old fluid, than replace the plug. than using a pump system or if you find a long enough hose (you need to use gravity to get the fluid in) you need to fill until the fluid just starts to spill out (ever so slightly).... to check the level you need to open your side plug and if a bit drips out than your safe, if not stick your finger in , if you can feel the level is just at the edge than it will be ok, if its a bit lower than you can top it off.

auto tranny fluid is suppose to be lifetime (although i dont buy that) manual tranny fluid i change every season, just because of the way i drive , its a bit excessive but it cant hurt

My auto tranny looks like it has plastic drain plugs that would deform permanently if you tried to remove them to change the fluid. Solutions?
