OIL filter urban legend? - ZR-1 Net Registry Forums

petefias · 11-12-2006

I'm not 100% certain on this claim, so I'm looking for validation from the real experts (you know who you're).

I'm claiming that the check valve is only half of the equation in preserving oil from leaking out while the car is sitting. The other half is the density of the filter element.

Even with a completely well functioning check valve the filter will leak out most of its oil through the filter element and through the center hole!

I.E. try pouring oil through coffee filter, it will be a very slow process. Use double filter and it will be nearly impossible. Use hot oil under pressure - no problem.

Time to put this urban legend to bed!

I was wondering about the flow rates. they seem very different? what is the optimium flow rates of a filter for a zr1 ? Is a high rate mean bigger particals go through? At what pt could the filter cause a loss of oil pressure? I guess I'm curious. I tried a mobil one and noticed a definate decrease in pressure on the gauge. So much so i stopped asap found a napa store and picked up one of their napa gold 1324, which I believe is made by wicks. any insite would be a great help.

Interesting post about the difference in oil pressure with Mobil 1. Some time ago I was reading info about Mobil 1 oil filters on the website "Bob is the oil guy". This site is was highly reccomended because of the knowledgable people that post on it. What I remember in regard to Mobil 1 filters was this. They said they didn't flow as well as other filters due to their restrictive nature. I recently went back into that website looking for the info Iam speaking of. I couldn't find it. Other filters were reccomended due to thier flow rates... however... I don't remember which ones they mentioned... will have to keep looking.
