Me either - having a plastic sump plug would annoy me. Though I guess that they just got tired of people stripping threads in alloy sumps and decided to use something even softer.Holy ****, never heard of this.
Yes, hence the need for a plastic drain plug.Are the pans plastic as well?
Oh, that's interesting FedWrench. I only work on my own cars, so no experiece with more recent stuff, but just wondering what's the reason for going to plastic sump pans. Is it cost saving or weight saving or some other reason?Yes, hence the need for a plastic drain plug.
We have new plugs in stock at the shop. I'm assuming they damage easily. I'm not looking forward to working on them.
I also was told some vehicles indeed do have plastic oil plans too. Not sure how I feel about those either.
I saw a plastic drain plug on what I think was a Ford back in mid-2017. But I haven't seen one since.
However I'm going to guess these things are unfortunately more popular on newer vehicles... We'll see after I've been at the new shop for awhile.
Can you put a Fumoto valve on a plastic pan?
lighter, doesn't rust, cheaper to make (can be molded as a single operation, metal pans require multiple steps), probably lower material cost, stronger than **** sheet steel they've were made of, less brittle than cast aluminum, they're quietier than metal ones. What's the down side?
Plastic + heat = brittle <<<Downside.lighter, doesn't rust, cheaper to make (can be molded as a single operation, metal pans require multiple steps), probably lower material cost, stronger than **** sheet steel they've were made of, less brittle than cast aluminum, they're quietier than metal ones.

oxidize and crack like all plastics will, heat accelerates it.lighter, doesn't rust, cheaper to make (can be molded as a single operation, metal pans require multiple steps), probably lower material cost, stronger than **** sheet steel they've were made of, less brittle than cast aluminum, they're quietier than metal ones.

Engineers design parts, not accountants. But your angle is more funcause the accountants said that is the way to go. Why spend $3.79 on an oil pan and plug when one can spend $3.69 and save 10 cents a car. Even with warranty claims, they make millions.
Before or after the alluminum one cracks or the steel one rusts? (I had a Land-Rover 2.25 oil pan rust enough to leak, and require repair. It's 3/16" thick; i've seen people use them to lift the whole truck.) Before or after the rest of the car is scrapped?Plastic + heat = brittle <<<Downside.
Never in my life would I have thought someone would argue that a plastic oil pan is better than steel or aluminum.Before or after the alluminum one cracks or the steel one rusts? (I had a Land-Rover 2.25 oil pan rust enough to leak, and require repair. It's 3/16" thick; i've seen people use them to lift the whole truck.) Before or after the rest of the car is scrapped?
They've been around for 20 years, including in a bunch of heavy duty applications. The problems I've heard about have been gasket problems, hardly uncommon with metal ones.

Fumoto's website says they're aware of this new development. I got this warning on a recent purchase:
"In some cases, this model has a plastic drain plug. We don't currently have a solution for the plastic plugs. "

What tool(s) are you guys using to remove and install plastic oil drain plugs? Any suggestions?
Snap-on is now selling plastic socket sets and a ratchet? How long are the plastic tools guaranteed to last?Snap-on has a special plastic socket set (flank drive!) and plastic Dual 80 ratchet. $216 and $112, respectively.

If there's no oil under it there's no oil in it.Remember the Land Rover motto: If it’s not leaking it’s empty.
My response was more to the plug before I kept reading and found we had plastic oil pans too. Plastic valve covers seem to be doing alright from what I've seen. In my experience, polymers+oil+heat+time+stress/impact hasn't been that great.lighter, doesn't rust, cheaper to make (can be molded as a single operation, metal pans require multiple steps), probably lower material cost, stronger than **** sheet steel they've were made of, less brittle than cast aluminum, they're quietier than metal ones.

We design for a manufacturer warranty period and depending on market for a ~200k km vehicle life. I expect plastic pans are fine but I'll still question novel methods every time. We all remember how CVT's did initially. Like all things, plastics have come a long way but made me question if there wasn't ulterior motive to force customers to get oil change at service center only (though OEMs don't care much to line dealerships pocket as much as their own). It brought me memories of apple products and their resistance to fixing your own but apple owns their service centers unlike auto.Engineers design parts in accordance with the parameters set by others including accountants that run many companies now.

Ford, GM, VAG seem to have the most issues with plastic cooling system components.Currently living the dream with Ford's plastic thermostat housing . . . on my third one.

Ronin got a valve for the plastic plugs.
