I do the same, although I forgot to fill the oil filter this last oil change when I put it on. Probably doesn't matter too much if you fill it or not if you do the momentary cranking trick, but I do think building pressure before starting does help.

 

I don't do it after oil changes, but I do use the feature when I start the car up after sitting for 2 or 3 months.

 

same. Mine is stored for about 6 months out of the year, I'll prime it after it gets out becuase that's long enough for oil to come off the metal surfaces and drip down to the pan.

I don't feel like doing it after an oil change makes any difference. I mean before the change you get your motor and oil hot and all the surfaces are coated with oil. By time you change the oil and start it up there is still tons of oil on the bearings and surfaces.

 

If I had a car I intended to keep, the Accusump would be on it, I think. Never start with a dry bearing again.

 

Hello,
Your subject interests me a lot !
I didn't know this trick !!
But I don't understand one thing : Doesn't the engine start by pressing the brake pedal, the accelerator and the start button ?
Can you explain it to me again ?
Thanks

You push the accelerator pedal all the way to the floor and hold it there while pressing the brake pedal with your left foot then hit the start button and release. The engine will turn over for 10 seconds then stop. Just keep the gas pedal matted to the floor. After that 10 second shut off start normally. Foot on the brake hit the start button again.

 

That’s what I was thinking. How is this done on a m6?

Same thing, except hold clutch in, floor the accelerator pedal and crank engine. (Set parking brake if you want). This is a feature to clear a fuel flooded engine, engine cranks but injectors don’t spray. Most cars will do this.

 

My 2014 Accord doesn't do this, revs to the moon. Don't ask me how I know.....

 

The second that motor spins its sending oil. I wouldnt worry about it too much.

 

The advantage of doing this is to pump oil throughout the system without the excessive load on possibly dry bearings while firing of the cylinders. It's a great way to lube things up after the car has been sitting or after an oil change.

 

Wondering how much raw fuel if any is flooding the cylinders…to the people who do this, when you finally go for start, do you recall what the exhaust looked like??? to be precise, did look like it was flooded after it fired up (rough idle)???

 

And the raw fuel washing the oil off the cylinder walls.

 

If your bearings are dry after draining your oil or letting it sit, you need to use a new oil. I can understand it if its been sitting all winter or on a new build but people are overthinking the oil change.

Bingo.

Doing this It cuts fuel not spark. In my boys RX8 tells you to do this procedure in the owners manual if the car is flooded

 

I would not own a car that needs "special starting procedures" after an oil change. So I own a Dodge. Of course no car requires special treatment after an oil change. It's a myth, begun by people who have no experience with repair, rebuilding, or modification of piston engines.

Hello,
For my part it is not specifically a procedure after an oil change !
But increasing the oil pressure in the circuit before the engine starts is just very good for it, knowing that it is when starting that it "wears out" !

Takes an hour or whatever to change your oil and fill up the new oil filter before spinning it on. There is no difference between that and your car just sitting for an hour on any given day, and your car sits overnight all the time or even for weeks. Use a good synthetic oil and change it twice a year, unless you track your car.

Modern oil and bearings etc are pretty good. I tore down a couple of LS engines recently, one from 2004 and it had to have like 150K miles or more, and the bearings looked brand new and the cylinder walls were pristine.

Hello,
I can tell you that it takes a lot more time for the circuit to be under pressure between an engine that ran a day ago, and the same one that ran a month ago !

It's not hurting anything to prime the system with oil doing the accelerator to the floor method. It literally takes 10 seconds and will insure you have adequate oil dispersed throughout the engine for immediate oil pressure to the vital areas. Dry start is a real thing, believe it or not.

Hello,
Totally agree with you !
Bruno (French)

 

Maybe I'm missing something. If the starter is turning that means the flywheel and crank are turning. Along with all other moving parts. So where is the advantage to this? Either way the internals are moving if you start it or if you do this.

 

When the cylinders fire off with fuel/spark on initial startup and there isn't adequate oil pressure, it puts a load onto the crank and rod bearings. Just spinning the engine without the cylinders firing, brings oil pressure up without that force to the "dry" bearings, they are just spinning with no load force being exerted.

 

I can almost smell the obsessive-compulsive disorder......
Just start the damn engine.

 

 

I just recall the old days, many decades ago, that the hydraulic lifters would tick for several seconds until the oil pressure built up. To each his own. As we know, old habits die hard. Love the comment about OCD, because that's how I have always been with my cars. But that's just me.

 

And the raw fuel washing the oil off the cylinder walls.

I’ll say it Again, this procedure of flooring the gas pedal and cranking the engine it doesn’t start because the injectors are not commanded to open, ie-no fuel, no start, no cylinder wash down from fuel.

 

OK then.

 

I can't imagine how some people make it through the day how they obsess about so many trivial things these days.

147,000 miles on my daily, no break in, driven like it was stolen since day one with the first street long burnout accomplished leaving the dealer after delivery, no silly catch can, sits outside, driven year round even in, hold your breaths, the rain 😲.

The only thing ever done was oil change every 6k, and normal maintenance (air filter ect).

It's just a car, a Dodge at that, its built ram tough, enjoy it life's short 🤣

Hello,
Don't be critical, everyone does according to their desires, ideas, and experiences !

OK then.

Wasn’t meant to be snippy, allot don’t read a thread from the beginning. To each his own, if it makes one happy do it, I’m pretty anal and I even don’t do this. My daily, a 04 4Runner just rolled over the 270k mark, I’ve never primed it once. Did head gaskets last year, here’s what the pistons and more so cylinder walls looked like at around 250,000 miles, Walmart Valvoline 5W30 Full Syn High Mileage every 3500-4k max with a good filter.
Even the intake and exhaust valves still clean, high speed daily highway miles, no chance for carbon to start 😆

I didn't think you were being snippy. I'm sure you're right.

Right?????????? Think the rest of the world does this too???????? I take it they never have watched Roadkill either.........

 

The scientists at Kendall frown on this practice, they say just start it, don’t shoot the messenger
