Why the change to the Mobil 1 Advanced Fuel Economy?
because of outside temperature. -25 Celsius to -30 Celsius every day for the past 15 days. where i live -30 Celsius happens at least 20 times every winter. lower than -40 Celsius about 4 times every year. it is fairly cold. and i don't have a block heater. i need all the help i can get. Mobil 1 Advanced Fuel Economy 0W-30 is a fantastic oil for extreme cold. but the US version of the Mobil 1 Advanced Fuel Economy 0W30 appears to be not the same as Canadian version. the Canadian version appears to be more suited for extreme cold.
I have never changed the crush washers on either one of my cars and they don’t leak.
You were who I was thinking of

How are you liking the Amsoil High Mileage? What OCI are you doing with it?
Because we are trying to get rid of abbreviated product names by converting them to the full name.
It runs great in this engine. I love it, but I might try the Amsoil Signature Series in this one soon. Going to run the High Mileage oil for 7500 miles.
I get rid of crush washers (ones that actually crush like a spark plug gasket washer) and go with a copper or aluminum drain plug washer. Never have to change them out.
I’m switching to a Gold Plug next oil change, and I think they use these. I might try re-using them based on the good experience here.
I've got two Gold Plugs in use, and the metal gasket they come with can be used over without concern. I never change out any copper or aluminum drain plug gasket and have never had one leak in decades.
And just to clarify, just a regular gasket not one that crushes? The Nissan OEM ones are copper crush washers. They are a big pain to get off the plug actually.
Yes, plain copper or aluminum drain plug washer gaskets that don't crush. Like this one that came on a Gold Plug. I never change them, and yes crush washers are a pain to remove from the drain plug ... another reason to go with one like on this Gold Plug.
I have two. ‘85 & ‘88
