From reading through this group I know the issue of the true oil change
capacity of the Elantra is less than stated in the manual. (I recently 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)
