Wipe off old oil from filter base plate on engine, smear a LIGHT coating of motor oil on the new filter o'ring, hand turn until the filter is snug tight (not over doing it), then go another 1/4 turn. I never had a problem with it being loose or removing it.

Don't most filters say oil the gasket and then tighten 2/3 or 3/4 of a turn after the gasket contacts the base plate? Has anybody had trouble after following the directions? Duh? I never have, although I must admit I may not quite make the 2/3 by hand sometimes and call it good enough. I have tried taking them off by hand, but it is easier and quicker to grab my 16'' Channellocks. Great tool, 1,000 other uses a filter wrench would never manage.

Hand tight. Most manufacturers say 3/4 turns after the gasket contacts the block. I honestly have no idea when that happens, and I am sure hand tight is more than that specified.

I always feel contact, then turn another 3/4 to maybe 1 full turn. Every week when I check the oil, I always feel around the gasket for leaks (never have any) and make sure I can still turn the filter a little bit by hand. Have been doing that ever since the time it took me until 3 or 4 in the morning to get a filter to budge.

Rather than getting a hand cramp installing from an awkward position, I use a strap wrench. That's what tools are for! Once it contacts the base (I have no trouble telling when that happens), I simply follow directions and tighten it to specification, usually 3/4 turn. I see no ambiguity in this procedure. I like to lightly butter the rubber gasket on the oil filter with silicone. This makes installation and removal a breeze.

Even at hand tight, the most you'll probably get is a slow leak. When a filter flies off suddenly, there was a much greater problem than just the tightness. I just don't like oil all over the underside of my truck and on my driveway, so I give it an extra 1/4 turn to keep leaks at bay.

Tighten with a breaker bar until the nipple's threads strip. Then stop just short thereafter on the replacement nipple. What is it about "hand tighten" people can't grasp? (yeah, there's a pun there)

Hand tight is good for most filters. However hand tighten is relative to the tighteners hand. I usually follow the instructions on my filter box to tighten 3/4 of 1 turn after gasket contacts base. I've tested and my "hand tight" is approx 1/2 to 5/8 turn after filter contact base. Likely plenty good, with no leaks. I do need a wrench to get it off though, regardless of installation method. I use a cap-style wrench on my socket drive and never have a problem with removal. I also use mechanics surgical gloves i bought at pep-boys. It's nice to finish the oil change, take the gloves off and my hands are still nice and clean. They also help a great deal with grabbing a hot filter.

What often limits me on the 'hand tightening' is I've owned a few cars that had oil filters in very unfortunate locations....a cap wrench was needed to get it to a legitimate 'hand tight'. I bought a set of mechanic's gloves at Pep Boys for my last oil change....rubber palms and a stretchy-mesh on the back side. Nice for grabbing (and tightening) slippery oil filters. I did get some oil on the mesh, which quickly soaked in, but I washed them in the sink and hung to dry...good as new...too bad they're not rubberized all over.

For the cans, hand tighten, typically 1/2-3/4 turn after contact. For the cartridge types, the tightening torque is often embossed on the canister. I suspect most dealers are using the five-digit torque wrench on those, too. These aren't seeing high PSIs as hydraulic systems go, so there's no need to make it into rocket science. But for those who must, I suggest a torque angle gauge at exactly 304 degrees.

I thought it was "tighten until it gets loose, then back off 1/4 turn" [Big Grin] Seriously, what's wrong with the instructions on the box? I don't understand what's so hard about following them...

realdeal, I get the impression you're a novice. Don't be afraid to have some confidence in yourself. You'll probably do a much better job than some oil jockey at a quicky lube place. Search "jiffy lube" and you'll get hours of reading some horror stories.

i probably over-tighten. 3/4 of a turn after the gasket makes contact with the block just doesnt feel secure to me. so, for peace of mind i just hand tighten until it feels snug.

Thats pretty much what I do, just to contact than 2/3 further (3/4 if it was an easy 2/3). I have a little piece of cushion gum I use for traction when taking them off by hand...

3/4 turn for me (after the filter first contacts the base). I use a smooth filter wrench to tighten 'cause I don't have the hand strength I used to. Just make sure your wrench doesn't gouge into the filter while tightening.

Well, just how tight is "hand tight"? [I dont know] Not everyone has the same strength, so the manufacturers use "turn __ turn after gasket contact" instructions. I just changed my oil a few minutes ago, used a Texaco Havoline T-35 filter(appears to be a restenciled Purolator Premium Plus L14670). The instructions on the box said to tighten 3/4 to 1 turn after gasket contact- so I went one full turn , & used the old reliable hinged Lisle strap wrench for the last 1/2 turn. Of course, your decision may vary. [Cheers!]
