I ALWAYS run full synthetic in everything and it helps with everything from spinning easier and starting in cold, quicker oil pressure which is important in engine longevity, can handle longer intervals if you so choose (though I still keep a decent interval because oil is cheaper than and easier to change than an engine), and if there is a cooling issue will also handle the heat better. However it will find older gaskets to leak out of a lot easier and quicker, just something to think about.
If I plug my truck in, it starts easily into the 20s even with a couple of crappy GPs. But since I tried replacing those plugs and found the swollen heads wanted to separate from the threaded part and I now have two cylinders I need to repair for sure and am hoping to find a way to do it without taking the head off if I can since I was planning a larger truck project for next year which may include a complete rebuild.
Any ideas folks? I guess I should have just kept a can of ether in the truck just in case but it's too late now. Is it possible to block the precup's outlet somehow and knock the tip into it then use a magnet to drag it out the injector hole? Until I can do something to the engine, I won't run it any further than onto the gooseneck and borrow my brother's truck to pull it into a shed so I don't freeze my ball bearings off.
Any suggestions would be appreciated, then I can go back to driving the favorite truck in my fleet. And then I can implement some heater options I have been working on.
