OK, I’m not being argumentative here but let’s look at what a block heater does.
What happens to dino oil when it is subjected to sub-zero temperatures? And by the way, Conn., especially the coast, rarely sees prolonged sub-zero temps.
The oil viscosity changes, empirically it slows down, it simply doesn’t flow as readily. And what does a block heater do? It raises the temperature so that the oil acts similarly to a hotter environment. That’s all it does. Period.
What is the temperature reaction difference between dino oil and synthetic oil? Synthetic oil stays fluid. Amsoil and I’m not a dealer, stays fluid down to - 60 F.
Wear? Dino oils can’t come close to synthetic oils for wear. So even if your dino oil engine starts more easily it still contends with greater engine wear. And when does an engine wear most? In the first few seconds after starting. Does a block heater equal synthetic oil in starting wear? Not even close.
What good is a block heater when you blow a tire on the back forty and you have to leave your tractor out for two days while you get it repaired? None.
So if you want to indulge yourselves and buy block heaters, have a ball.
I’ll run synthetic oils in my engine and box, have a longer lasting engine and tranny, better fuel efficiency, less oil changes and save on electricity too.
Don't believe me. Take a look at the list of cars that come standard out of the factory with synthetic. Aston Martin, Porsche, Corvette, MB, etc.
How many of you have been inside a Porsche engine with mileage on it? I have. All I use is synthetic.
