I purchased an opened case of M1 0w40 ESP at a swap meet a while back to run in the Vette (Bottles were sealed). Took a closer look when I got home and one quart was M1 0w40 Euro, so I am trying to find for a good use for it.

I am assuming it will be just fine, but is there any risk in running Mobil 1 0w40 European Car Formula in my Ariens 306cc snow blower? The manual only lists 30 weights, 5w30, 10w30 and straight 30w. I have been running M1 5w30 in it since new. It takes exactly one quart to fill.

Thanks
