So my brother used to have a 2002 Elantra and now my dad has a 2007 Tucson. About every 2-3 oil changes I get a hold of the vehicles and do it myself, the other times it is taken to random quick lube places. I always use Purolator filters on Hyundais since they are readily available and of good quality. However they always seem to be a different size than what I remove. Here is an example. The used filter is from VIOC and had the smallest media I have ever seen! It is barely over 1" high. I thought it was a Champ labs filter looking at the base plate, but when I chopped it open, it looks like a purolator to me. Any input? BTW, the used filter had 8k miles on Valvoline bulk!
