Hello Group I hope everyone is doing well.

Ok, I was calling around different dealers regarding 60,000 mile service. One place told me that they also replace your fuel cap as part of the service. I'm scratching my head because 1.) that's not in the service manual and 2.) what does that have to do with the maintenance of the engine? The person explained that the gasket around the fuel cap can go bad or that there maybe cracks in the cap that's not noticeable and it affects pressure in the fuel system and can have a real impact on fuel economy of the vehicle.

Never the less, I went to another place to have the service done because I thought replacing the fuel cap was a justification to jack up the price. But I've looked on line and see that ebay sell's gas caps for about $20 (shipping included). I know it's $20 but would it make a real difference or have I bought into the sales pitch?

What are your thoughts on this?

I think they replaced the gas cap becaused of the seal....if it's not sealed properly you will get a CEL for that...

I would ONLY replace it only it it give me the CEL. Why waste the $20 for something you don't need?

BTW, I used to believe every sticker add 5 hp to my Honda Civic .

Just a data pt for those in NE Ohio:

E-Check will replace at no charge a failed gas cap during biennial inspection. Dunno if it'll have the Toyota "leash", though.

I think you can just order a new O ring

I took a quick look last time I filled the tank and I do not see any serviceable parts for the gas cap for my RX330. Not sure what this o-ring is and cannot find anything on the Sewell web site. It may exist, however, I do not see it at the moment.

has no effect at all on gas mileage. if no CEL, don't bother replacing

I haven't heard of it having any impacts on gas mileage

Wouldn't increase fuel economy but if your cap isn't sealing properly then it would make a difference to replace it. If it is sealing properly then it won't make a difference to replace it.
