DO NOT USE STP S3766 oil filters from AutoZone - warning!

[notenuftime]

I've been running fl1995 for five years no issue.

If you look close you can see that your old gasket stayed on the block. You double gasketed the filter!. Take it and the old gasket off. Put the new stp filter on and it will be fine.

wonder if this is yet another marketing thing to sell for higher price by claiming one to be a premium product, even if in name only.

I work at a napa and the pro select and gold filters are pretty close but not the same also all the store brand oil is Valvoline

Good eye! That would probably cause a leak for sure!

He has not responded since. Blaming a filter on his goof.

I had this happen to me one time on a Mustang that I used to have.

I had a stp once. It was hard turning all the way on.
Rather one feels tight or not, I try to look at the contact area.

I can't see the extra gasket, I see the cone shape of these new style gaskets on the filter but looks to me like the filter header is clear and flat ready to mate to the gasket if it makes it up there. Looks like the filter bottomed out before gasket even contacted the header.

There’s no second gasket there, that’s a 1/4 inch gap

Here’s your proof... Bad filters.

also... the gasket people are saying I left on is in the last pic

looks to me that they installed the mating surface backwards, with the dish facing inwards

This is what happened, you can see the difference in the mating surfaces in posts above. Part number on that blue filter is S3766.

Looks like the filter assembly machine was loaded with the top plate upside down.

Indeed!!

ALL parts on the shelf were like this. The mounting surface to the block is visually different

I trusted auto zone on this (for some reason....) and my truck puked all 10 quarts in about 2 seconds out of a gap caused by the threads. I’d be out an engine if it wasn’t for my friend

I’d reach out to autozone corporate and to whoever the STP brand is and give them hell. Do it on FB or Twitter or whatever social media you use. Send them the pictures. I’d at least ask them to pay for the extra oil change. They owe you and whoever bought one of those in the shelf a replacement filter and maybe something for your trouble. (Not a new truck but something for the hassle)
