Drawbacks:
1. you could blow it up
2. the car will be stupid fast (yes that can be a drawback)
3. depending on your tires you may have serious traction issues below highway speeds. Like spin out and fly off the road.
4. gets expensive fast
except Chinese stuff sucks most of the time
Even your "craftsman" tools
"China" makes stuff as good as you're willing to pay for but if you want really quality you go to Taiwan
Vietnam and India are making the bottom level shit now
Look how long it takes to prime this engine using a drill
Careful observers will notice the engine is not turning over, they are just turning the oil pump
So are we supposed to do this every time we start the car?
Or just after a certain number of days? And what is that number?
And do we still have to do it if we use Ceratec or Amsoil?
Run the engine "dry", with the starter, at 2-300rpm for 15 seconds (how long are "the primers" turning the key, and how many times do they do it?)
or just turn the key and start the car, run the engine "dry" for 1 second at 200-300 (starting speed) and then for the one second until you see oil...
Do you think the oil evaporates off of the engines internals after two weeks? Or during an oil change?
What do you think you're accomplishing by putting oil where there is already oil?
Also, have you ever watched those engine tear down videos where the engine is broken, they've been sitting in a junkyard for a year or two...when they take the engines apart the bearings all still have oil on them...
The oil pressure sensor is right after the oil pump.
If you have a garden hose, you have pressure right after the faucet but that doesn't mean you have water coming out of the hose.
Oil pressure is driven by RPM. 5,000rpm is higher than idle. Starter turns the engine at what 200rpm...
Except that you don't know that it actually does push oil through the engine.
You hear someone say 'oh I do this flood mode thing to get oil going before I start it...', but is it even true?
You said 'it says', but you still haven't said what it is/was. Owners manual? Ford service...
So you're ignoring what ford tech instructs you to do? Why? Sounds like you're the one disregarding information.
it's not a small block ford with the old, different style oil pump.
It's in some years manuals, and it's flor clearing a flooded engine, not building oil pressure
We had this discussion either here or on 6G and there's some goober that does it when he hasn't driven the car for a few days...
E10 is weird
I can leave it in my riding mower all winter and after a couple cranks and a puff of smoke it starts just fine
I've left it in my push mower for two years and it's fine
my snowblower, though, if I don't drain it, it turns into goo in the bottom of the carb in just a few months...
