my friend uses air compressor to drive out all the oil inside his engine when he does his change oil. he said it's better because it would spit out all the oil from inside the engine. he puts the hose inside the oil fill hole. is this good or bad? i always change my oil without it and just wait to drain, although it wouldn't drain it all unlike using a compressor. any insights?

 

Your friend is stupid.

 

really REALLY REALLY F#@(ING stupid.......sometimes oil and water from the compressor itself comes out from the line, thus why it feels fresh when you blow the compressor's air on your skin.

and all of that is just blowing into your motor........honda made the motors to drain, and i believe what they say goes, when it comes to THIER motors.

 

pointless, get the motor warm and drain it. It isn't freakin rocket science so don't over complicate it.

 

this reminds me of a guy that would drain his oil and then turn the motor over to get the remaing oil out.

doing things like this totally negates the preventative intent of changing your oil.

 

Maybe he should consider removing the oil pan and licking it clean too.

 

lmfao this haha

 

I put a garden house in the fill hole to flush out the old oil.

 

 

LOL! Typo FTW!
Seems like you might get cement, wood, glass, drywall, nails, etc. stuck in the oil passages, but I guess you figured out how to avoid all that. Does it work well? Better than seafoam? I'm gonna try it this weekend!

 

oh wow. another person who should stay away from cars...

 

x2.

OP, your friend needs to stay away from cars forever.....

i had a friend ask if using power tools to remove the drain bolt would make it easier one time... this is proof that people with high IQ's ARE STILL RETARDED...
