Which is better, big or small oil filter?

Think the small filter is common with gas engines while big filters for diesels due to more engine soot, dirt inherent in diesels.

I'd use the oem size in any diesel engine since some are 2-stage filters- a full flow and bypass filter(much finer filter). Haven't heard of a bypass filter in common gas engines.

The OEM TD42 filter is huge to increase filtration area. And there are two of them to increase the said area even further.

The increased speed of circulation would be useless if your filter got clogged by crud halfway before the next oil change.

Just don't race your engine on cold mornings and you would not have problems with circulation speed.

dont know with oil, but for fuel filter, i have a better experience with big filter than small one as it can easily clogged up.

stick to OEM filters and change oil every 5K kms..

dun sa revo gas na gamit ko.. maliit ang oil filter.. sa revo diesel, halos twice ang laki ng oil filter compared sa gas model..
dalawa nga fan/alternator belt ng revo diesel compared sa mga revo gas.. kala ko kasi eh standard na dalawa fan belt sa revo.. kumbaga eh meron reason mga car manufacturers kung bakit ganon gamit nila na mga filters, belts, etc..

pero parang mas okay ang malaking oil filter dahil hindi agad babara ang oil... at mas importante na hindi masira engine...

Ok, I agreed OEM big filter is better. Guess I have to change mine on the 2,500km mark. But, I've notice that when this small filter was install the engine fired up well during start-up. May protector daw ang TD42 kinda like an engine shut off mechanism when oil level goes down to a dangerous level. Everytime I had my oil changed nag stop ang engine after about 10 seconds. This time hindi siya nag stop.

revoGSX:::The maunufacturers are now leaning towards smaller oil filter. maybe it's the cost ;)

Bakit yun kay Boybi maliit...

...yun oil filter niya.
