    What... No.. That's not true at all.

    If you get sand (worst case scenario here) in your intake, it goes in through your head and into your block, where your pistons will grind it against the cylinder walls and - like you quoted - scratch the fuck out of your sleeves.. Good oil wont prevent that as you should not have oil in your cylinders. Oil in your cylinders means you're burning it because it's leaking in somewhere - valve seals, piston rings etc..

    A great oil filter wont catch the sand and prevent initial damage.

    Your air filter being a piece of shit and your oil filter being awesome does not even things out. Not at all. Two different parts of the engine dude.. Where air and fuel go is a different animal to where oil and coolant go..

    Ok...Well I seem like an idiot now lol I'm just curious though, how come for warranty purposes on new vehicles, the interval oil changes shorten for "severe" driving conditions such has dusty environments and so forth?

    Re: OEM Air Filter Performance vs Aftermarket - Interesting Article with Data

    I'm going to make up an answer to that one and make it seem like I know exactly why.. Here's an example.. My drive home today consisted of an hour (60km) of highway and back country hills etc. - usually this takes me 45 minutes. It took me an hour and a half today because the snow storm we had (and why I was sent home early from work) ended up pushing snow higher than the guard rails and I was literally plowing snow with my bumper on my truck for a good 40km. Skimming is more accurate to plowing..

    Anyway. I couldn't get out of 4th for most of the drive. 3rd was the gear of choice - some hills I was in 2nd. The entire time I was putting additional load on my engine than I normally would have. Pushing through snow requires more effort on the engine than nice smooth pavement, and with that load my engine temps would increase and the overall stress on my engine would increase. My oil would have to work harder to keep things lubricated and clean.

    Dusty environments make your engine work harder, any extreme temperatures etc.. With your engine working harder your oil will break down quicker and not do its job as effectively. That, to me, is why you change it more often..

    Another thing with higher flowing filters is if you aren't tuned for it there's a very good chance you're going to be running lean under load which is not good
