Totally false narrative. No one says these things. Straw man induced statement, like claiming people say "20 wt. will make you car blow up".But I thought engines running x20 were only designed for a 150k mile lifespan. But I thought x20 was no good for the heat. But I thought it was only for CAFE and detrimental to the customer. But I thought x20 hasn’t been around long enough to know.
But what I’m definitely sure of is it it WAS running x30 it would have made it to 3 million miles
Never happens.
