did the first oil change on my '05 GT and, using the manual as a guide,
overfilled it by dumping in 4+ qts.) Anyway I was wondering if anyone
has ever had any word from Hyundai on whether the manual is wrong, or
possibly, is the dipstick wrong, IOW, is it really supposed to take
4.25 US Qts? It just baffles me that this could have been wrong in the
manual for so long (it seems this problem dates back several model
years) and they haven't corrected it. Right now my oil level is
registering about 1/4 inch over full and I decided to just leave it, as
it didn't seem to have any negative effect on the engine - no evidence
of foaming, etc, but is that too overfilled? On my Jetta there were
warnings that it could damage the catalytic converter if overfilled. I
was also questioning the viscocity chart in the manual as opposed to
the webtech chart - it seems the manual says go with 5/30, but the
webtech site recommends 10/40 if the temps are warmer (I live in
northern NY and used 5/30 for this change, but am wondering about next
time when the temps will probably (hopefully) be in the 70-80 range)
You should always check the dipstick as you add the new oil. Once you
reach the full line, start the car, let it run for ~30 seconds, then
shut it off and let the oil drain back into the crankcase for a few
minutes. Check the oil level, then top it off if necessary.
That may be what it takes to fill a dry engine. You'll never get all the
oil out of an engine once it's been filled, but there shouldn't be a
I can't say for sure, but if it was my car, I'd drain some of it out.
5W-30 should be fine at those temps. That's what I run year round and it
will sometimes get into the 90's here.
