I changed my oil and filter for the second time tonight. i was talking to one of our members about a month ago about something or other and he was telling me about a disaster he had with his Stang that morning, when started the car after his oil change and just putting 6 qts of Mobil 1 in, he dumped the whole thing in the driveway...he told me the oil seal stayed behing from the old filter, so when he screwed the new one on, it had double gaskets, and the oil just went spewing right out and into the driveway...So tonight I remembered his words after I dropped my filter, I went back up there to clean the pad and when I looked at it the oil filter seal was left on the pad/ was no longer on the old oil filter!!!
So a word to the wise, always check and clean the pad off before installing your new oil filter!!!!!
Also he is lucky he discovered it before he took off driving ...self explanatory!

 

I would say its common sense to always check for that, but then again im sure there are some who will really benefit from this post so ...

 

I have changed oil over 100 times and never had that problem, except once. And I promise I will never do that again, ever. I talked to a few auto mechanics and they all made that mistake at one point in their careers. The key is always in the details. And I am sure that in their next job, they learned from their mistake.

D2toys, who made that mistake anyway? I'll deny it

And by the way, the oil drip pan got 99 percent of the spill, so I felt less stupid, if it was any consolation. :bang:

 

Yes I was an auto mechanic for many years. Only made that mistake once. So you definitely learn something from it.

 

I always examine the old filter and the engine block mating service when I change the oil. It just seems like common sense to me.

 

I always take a rag and clean the surface, so this should never be a problem for me.

 

I left your name out, but since you are admitting it, You did my friend!!!

 

One more point to add, I think the dipsick is wrong in this car. 6 qts only puts me halfway up the cross hatched area :bang: . I am sticking with the Ford spec of 6 qts and going to ignore the dipstick...anymore info on this would be appreciated.
EDIT: after I let it sit all night I just checked it again and it is now 3/4 of the way up the dipstick...and for those of you that are going to ask, I did start the car after I changed the oil, so the filter IS full.

 

In addition, a good habit to get into is to wipe a nice layer of fresh oil around your new filter's gasket. This, combined with cleaning the mating surface on the block, will allow your filter to be removed more easily at your next oil change, and also lessens the chance that the gasket will stick to the block.

This is probably redundant for many of us, but it's a good reminder, and perhaps may help out a noob.

 

same here. it never pays to be in a rush

 

D'Oh!!! A rag... brilliant!! All these years I've been licking the dam thing clean!

 

I myself always check for the gasket on the old oil filter. Just like I check to make sure the new one has a gasket (bought an oil filter once that the gasket was removed... from now on I check in the store). But thanks for the heads up.

 

Your welcome...It sounds stupid, but if it saves even 1 mustang, it was worth it

 

It happened to me the second time I changed my oil... I always check because it happened in one of my 66 stangs. That, and I now wipe off the gasket seat with a rag every time.

 

I've never had a gasket remain on the engine, but I always check. However, I have mistakenly installed a wrong oil filter model and dumped about 4 quarts of synthetic oil in my garage.

 

Same thing I did. I've seen every mechanic do it once. Them you learn that cleaning up oil stinks.
