Short oil filter verses long oil filter

Short oil filter verses long oil filter

Postby zundapp57 [OP] » Mar 11 2012, 12:20pm

I always used the longer oil filter on any small blocks I have run in the past . Seems like a no brainer longer filter holds more oil and has more media. All the parts stores call for the short filter. That oil pan on the 6.0 is plenty long enough for the longer filter. Any advantage to a smaller one other than clearence?

In the various tests that I have read, there is not much difference in the amount of filtering that occurs in the different filter sizes. I would stick with the OEM recommendation.

Bigger filter does not necessarily mean better filter. Whenever you use a larger filter than recommended its very important that the filter be designed for that application or else you may be using an inferior filter thinking that because its bigger and fits, it must be better.

Filters are made to withstand the pressure created by the specific motors, a bigger filter is weaker than a smaller filter as well. I have seen some "Blow Out" being they were not made for a specific motor.
An example is, drag racing, if you put a standard filter on a dragster, it would blow off on start up. So, you wouldn't want to put a lesser/cheaper filter on your motor and chance blowing your engine would you? Always use the proper replacement part.

I have built two race motors for my jersey speed skiff, small block chevrolets putting out about 375 hp. They run at about 6500 rpm. the oil pump produces 90 psi at that rpm. I always run a one quart oil filter, fram racing ,K&N, even purolator. Never had a filter ever burst or fail. Have seen other boats with remote mounts holding two one quart oil filters. I stand by my more oil capacity + more filtration = longer engine life. Also built the first engine In 1988, and still runs strong. the second engine is in my friends drag car.

I've been using the longer filters on my 5.3L engines with no ill effects. My 1999 Silverado had 272,000 miles on it when I traded it and never had an issue. I figure a little extra oil and filter capacity can't hurt. Some people are just afraid to go against the factory "recommendations' for fear the sky will fall or something. If it were bad to use the longer filter, imagine just how terrible it would be to install a single or *gasp* double remote filter! Of all the things to worry about, a longer filter would seem to be very low on the list.

I agree, more filtration and extra capacity doesn't hurt anything and is a good thing, you just don't want to go lesser or cheaper and take risks...
Its similar to heart surgery, would you go longer or shorter or would you go with whats proven to work? Id want whats proven to work so it doesn't matter on size, but I sure wouldn't want something that was made for a lab rat. lol
