You're right about Mobil. Same result here; hat, stickers, tool box decals and a signed letter thanking me for my interest. Valvoline also sent some oil change stickers and tool box decals but no hat. I had also requested some from Castrol. They emailed me back and said they don't do that so try to get some elsewhere. Pennzoil/Quaker State never even responded to my request.I primarily use the MyCarFax app to track maintenance but also use stickers just because I have them. I currently still have some ACDelco stickers I bought in a stack years ago, as well as some Mobil 1 stickers that I requested more recently. M1 was very generous with their swag, and included a hat and some toolbox stickers.
