Canadian oil change sticker
 

To confirm my theory, what does everyone say is the correct location for this sticker on GM cars? I say it goes on the inner fender of the side with the dipstick/oil fill. On Oldsmobiles, I believe it's on the left side valve cover. Anyone have an original car with sticker still on it? My original L34 has it on the right side, as shown in the assembly manual, but I've seen a small block Chevelle with it on the left side. Dale

On Olds 442, on the drivers side valve cover. These are seen on Lansing built cars. Can’t speak for other plants but that is what is shown on the assembly manual.
I have seen Oshawa built Chevs with them on the inner fender wells.

For a 1970 Chevelle I have seen them on both sides, sometimes upside down sometimes right side up and always on Plastic Fiber inner fenders.
I also make a very accurate replica of this label if you need one.
