Mach 1 Oil Change - Filter put on Dry Per Ford Recommendation

[Bulldog9]

You are incorrect

Gezzz I am not disagreeing with adding oil on the gasket I have always done it.

INCONCEIVABLE! Then again, it is FOMOCO ;-)

I always make it as tight as I can by hand.

Same here. Well, actually just a little less than I can by hand, so that I know I can also remove it by hand the next time, haha.

As for dry vs oil on the seal, I'd vote for dry to help prevent it from loosening, but there is always that little bit of oil left on the plate, so it ends up being an oiled seal anyway. I don't obsess over it.

Only one time I found a small spot of oil under my car, and it turned out that I could've/should've tightened it a little more during the oil change.

I'm glad this topic came up because I've been working on the same premise that I learned from Fram's instructions printed on their orange filters 3-4 decades ago...that is... a) lubricate seal lightly with oil, b) tighten until seal contacts base, and c) tighten 3/4 additional turn. I've even been marking my filters to know exactly when to start/finish my 3/4 turn.

While it has worked quite well for me for many years, without fail I might add, maybe I need to rethink my process after this enlightening thread.

FWIW, when I used to do my own oil changes on aircraft I (part-)owned. At least one of the manuals spec'd Dow Corning #3 on the seal. I still use it, at least when I can find my tube of the stuff; engine stoppages in flight are at least as annoying as on the ground. Looks like it's been repackaged/renamed; the tube I bought probably 20 years ago (at $20!) only has another 10,000 or so changes left. There was a torque spec too--the filters had a nut, 5/8" IIRC, on the end of the can (like K&N)--and it was low; I bought an inch-pound wrench to do it. My shaky recall says 18lb-ft, but that sounds high.

One time a looong time ago I didn't oil the gasket, the seal came out of its groove and bunched up. Felt odd, so I took it off and thought, "oh that's why."
I've oiled it ever since with just a very light film.

That is indeed odd, I have lubed the seal on filters for all the oil changes I’ve done to my cars in the last 40+ years. I always fill the filter with oil as much as practical too, but I’m sure that could be the subject of a whole separate thread lol. I spin it on until making contact then take note that it goes 3/4 turn past. Really, just hand tight. A seasoned mechanic showed me the best and easiest oil filter wrench for getting them loose… a huge pair of channel lock pliers.

I have been changing my own oil for over 60 years. From drop in dry filters to our spin on filters. I always lube the seal and if possible add oil to the canister or filter itself. I cannot ever remember having a leaker. JMO.

I have changed oil on all my cars and have always lubed the seal. But based on this recommendation by Ford I have not on the Mach 1 and have had no issues removing it and 0 leaks. Its actually impossible to not get any oil on it anyway, its always seeping on there.

I have always schmeared the gasket, no issues on my Mach 1 or my 22 GT.... But I twist the living F$#K out of it when I put it on by hand... I have a nice strong grip wrench to get it off.

Coming from the aviation world, I will always, always, always lubricate an oring. Which is basically what the oil filter gasket is. Also from the aviation world, I use DC-4. Dry is just asking for problems.

 

[ChitownStang]

8 oil changes on my Mach 1 and I always run my finger over the ring with a little fresh oil.
Hand tighten as tight as my grip will take it.
Never had a drop leak.

 

[cerbomark]

always lubed my filters. I wonder if the new instructions are gt350 related? They have more vibrations I ve been told, don t know, just a guess . I tend to over tighten so my filters never move, LOL.

 

[JetGray_Mach1]

Sounds like both people that have done it the conventional way “oiling the ring” and per the new recommendation “no oil on ring” have both been fine.

 

[AZ_Ryan]

Always lubricate the o-ring. They buck less.
