The Stovebolt Site Forums The Shop Area General Truck Talk the 1 quart larger oil filter?

Hello,
A few years ago I used to be able to buy an oil filter that held an extra quart for the '70 350 in my truck.
Anyone know the part number and if we can still get them?
Wally World used to carry them.
A PH20 or 30?
Thanks,
Mike

Wix 51794, Hastings LF226, AC PF932, is the "foot long" (OK 8") Chevy filter.

Napa or Car quest has them

If you are doing it for nostalgic or appearance reasons, it is OK, but with modern oils it is totally unecessary. It does't give you any more oil capacity (you will still have two quarts of oil in the filter when the engine runs dry) and any oil cooling benefits would be marginal and neeedless.

An extra quart of oil has no added benefit?
Following that reasoning, I could, in theory, remove oil to the point of having just enough to keep the engine lubed and still be safe.
This is not about an insurance policy for a leaky engine, that should be rectified ASAP.
Given a certain amount of contaminants being introduced into a liquid, would it not be better to have a larger volume in which to disperse the contaminants?
Fewer parts per (choose your X value) of crud would tend to decrease the exposure of crud to any given engine surface, right?
A unit of heat exposed to Y amount of coolant should be able to be dissipated to a greater extent by exposure to Y+X amount of coolant.
I am not a thermo-dynamic engineer, I just think that every little bit helps.
Are all the seven + quart oil pans being sold by Mellings, Hamburger, and the deep automatic transmission pans, etc... merely snake oil?
Just my $.02
Any TDE's or Petroleum Engineers out there that would like to wade in?
Take care,
Mike

I think what Baldy was trying to say is that you will still end up with the same amount of oil in your oil pan. However, I do agree that the conaminants and sludge that may be in your engine would be more diluted in 7 quarts of oil than in 6 quarts of oil.

You don't have an extra quart of oil that can be used, the filter is always full even if your sump goes dry. Think of it as having two cans of oil in the bed of your truck that you can't open. Added capacity is good, get a deeper or wider sump or go dry sump with a large reservoir, but don't depend on an oil filter for more usable oil. Change your oil every 3000 miles with a good filter or every 1500 miles with no filter to get rid of contaminants. The oil actually does a better job of getting rid of contaminants such as acid and water at 250 degrees than at 180.

The only advantage I can see to a bigger filter is more filter media exposed to the oil. It won't filter any better, just longer, before it clogs up. That's the reason for running the extended filter on a commercial engine, longer runtime between changes. If I'm running my smallblock engine from New York to Los Angeles on a regular basis, I can change oil and filter in L.A. and make a round trip before it's time to change again, if I'm running the big fliter.

I,ve used one on my partners 6.2 deisel for 20 years. It gives an extra margin of filtering. Watch out it doesn,t hang too low on a small truck & get hit on something. That would spoil every thing.
