Title: Looky what I found,, Post by justin_o_guy2 on 06/19/11 at 07:20:26 http://www.trustmymechanic.com/motoroil.html OOokay,, Im lookin to get down to Savin $$$ & time on oil changes,, apparently cheap filters are a bad plan.. As with oil, many filter manufacturers provide data regarding their filters. Unfortunately, often the way that data is presented is VERY misleading and often VERY lacking in substance. For instance, many filter manufacturers will make statements such as, "Our premium line of oil filters are rated at 10 microns" or "Our filters will remove particles as small as 8 microns". Neither of these statements mean ANYTHING at all. Filters are not "rated" for certain micron levels, they ARE tested for filtration efficiency related to certain micron sized particles. In other words, it can be said that a filter offers 97.3% efficiency at removing 15 micron particles on a single pass. But, saying that the filter will remove particles as small as 15 microns is meaningless, since no efficiency data has been supplied. Chicken wire can remove particles as small as 15 microns as well - it just won't be very efficient at it. Theres a free Ebook link at the bottom of the page. |

Title: Re: Looky what I found,, Post by justin_o_guy2 on 06/19/11 at 07:40:26 Okay,, some O you Guru types can have a go at this part.. ow, I know this is going to be tough to understand, but, let's give it a shot. First, the fact that this test was conducted at all, suggests that there ARE various and wide ranging filtration efficiencies available on the market. Second, according to this study, moving from a 40 micron filter to a 15 micron filter reduced engine wear by 70%! POP QUIZ: How much longer will your engine last if you can reduce engine WEAR by 70%? It's actually NOT what you probably think. It's not 70%. Consider this. If you cut engine wear in HALF (50%), it makes sense that engine life should be DOUBLED. Thus, cutting engine wear by 70% (considerably more than 50%) will actually FAR MORE THAN DOUBLE your engine's useful lifespan. The added cost? Believe it or not, the difference in price between a standard 30 or 40 micron paper media oil filter and a premium synthetic media 15 micron filter is only about $10 per filter (maybe even less in many instances). Now, on the surface, if you didn't know how much engine wear you could save by upgrading your filter, that might seem like a HUGE increase. But, consider this. First, some of these higher efficiency oil filters are actually designed for longer change intervals (as much as 4 or 5 times as long - easily making up for the additional filter cost). But, even if they weren't. Even if you changed them every 3,000 - 6,000 miles like a cheaper conventional filter, over the life of your vehicle, the additional filter cost would amount to (AT THE ABSOLUTE MOST) about $500 over 150,000 miles. That's peanuts compared to the savings in engine wear and the increased engine longevity. We already said that you could easily save between $2,500 and $4,000 PER YEAR by doubling your vehicle's useful life. Over 10 years that's a savings of $25 - $40,000 for a simple $500 expenditure in filter upgrades. Sound reasonable? at all? |

Title: Re: Looky what I found,, Post by verslagen1 on 06/19/11 at 07:46:28 Great info if you're worried about your car. but as far as our little savage is concerned... where are you going to get a 10 micron filter? and what's going to do to the oil flow rate? |

Title: Re: Looky what I found,, Post by Serowbot on 06/19/11 at 08:07:44 Exactly what I was thinking... If you're getting more filtration from the same size filter, it stands to reason that this filter will clog up sooner... as it's capturing more stuff... Run with a clogged filter, and you might as well run with no oil at all... So if you run with a more efficient filter it seems like you need to change it more often. Super small particles will cause less wear than larger ones, so there must be a point of diminishing returns on filtration... You want a filter that will capture particles of a size that will cause wear, but not clog itself up with smaller ones that don't, thereby allowing maximum oil circulation... (I said, "thereby",... how cool is that?)... ;D... |

Probably right, Bill.. It's just that I'm so lazy, and that's the yukky part of the oil change... if I didn't do an alternating fluid change, I'd probably still go the same interval on the filter... I'd just spend 2,500 miles saying,... "I really should do an oil change, soon"... :-?... |

Title: Re: Looky what I found,, Post by Boofer on 06/19/11 at 18:54:19 I realize that a lot of the dirt in oil comes from combustion, but the air filter is often overlooked in these discussions. I don't have a guess as to which contributes the most to dirty oil, but the air filter shouldn't be forgotten; especially with some of the open filters some of us run. And Serowbot or Justin mentioned the other day that just because oil is black doesn't mean it's not lubricating. |
