I have replaced my canister filter on my 62 with a spin on,to make oil changes in the garage easier. I will reinstall the canister for judging purposes. I would like to know if the correct spin on filter is the shorty or the longer one. Thanks

Re: replacement spin on oil filter
Rob,
You should be able to use either one (AC Delco PF-25 or PF-35). As long as it doesn't touch the exhaust pipe or clutch linkage use the PF-35, the only difference is the amount of oil they hold, more is better and your original canister held a whole quart.
BTW: I just went the other way...got rid of the spin-on adapter and went back to the original canister/cartridge type unit. Once you get the hang of installing the original type it is actually less messy than the new-fangled spin-on filter. Especially when it comes time to remove it. The secret is to NOT hold the canister when removing or installing. I assume you fill it full of oil before you install it, and it should be full when you remove it. Hold it by the bolt only, use your other hand to balance the canister and you won't spill oil everywhere.
I guess the real question that should be asked is: Do modern spin-on filters offer superior performance over the original canister style cartridge filters that came as original equipment?

Use a long one if it will fit, won't hurt a thing.Comment

Re: replacement spin on oil filter
If you can fit the long one, the best AC filter is PF35L (not PF35). If you need a short one, the best AC filter is UPF25 (not PF25). Both of these filters use 10 micron filtration elements. They are far superior to standard filters, especially the old cartridge type.Comment

I agree with 'Wild Bill'; if you are going to use the spin-on type cartridge, your best bet is to use the synthetic media filters, preferably the AC-PF-35L(GM #25013454) or the filter which will be replacing the PF-35L which is the AC-UPF-1218(GM #25322841). These should fit on your engine without interference.
As a matter of fact, the availability of the new synthetic media filters should be your PRIMARY reason for using the spin-on filters. Basically, there is no significant difference with respect to filtering efficiency of the old 56-67 replaceable element style filters and the newer 68+ "spin-on" type. The old filters might have a little more capacity, though, due to their larger size. However, the availability of the new synthetic media filters changes everything. These filters, which are NOT available from GM in sizes to fit the old 56-67 cannister filters, are FAR superior to the old paper-element filters used in most AC and other oil filters previously. In fact, this is probably the greatest leap in filtering technology since the invention of the oil filter. I doubt that GM will make sizes available for the old cartridges in the future, either. I just don't think that there's enough demand anymore to justify it; you're lucky to be able to even FIND the old elements in an auto parts store anymore. However, aftermarket, niche suppliers like Amzoil might come out with one.
Also, an interesting side note here. I understand that some of the new GM engines will be coming out with a new style oil filter. It will be a high-strength, two piece plastic housing which will have a fitting to "spin on" to the engine. To replace the filter, you remove the housing from the car and seperate the two halves. Then, you remove the filtering element, replace it with a new one, reassemble the housing, and replace it on the car. You see, this design is environmentally friendly and saves all of those steel cartridges going to landfill. The elements are also much easier to recyle and dispose of in an environmentally friendly manner. Does the concept sound familiar to anyone? Could this be another example of "back to the future"?In Appreciation of John HinckleyComment

Re: replacement spin on oil filter
when replacing your spin on filter to prevent oil running everywhere punch a hole in the bottom of the filter with a hardened nail and then turn it loose a turn and the filter will empty and not run all over the place when you take it off. :)Comment

Re: replacement spin on oil filter
Thanks to everyone for your imput. I got a lot of good info that I will put to use. I was not aware of the better synthetic filtering element.Comment
