one, look at hobo's post and two, taking ur foot off the gas dosent keep it at a certain RPM duipshit, it may be at 2500 at one point, but it is eventually working its way down to idle, ever notiuce how you LOSE SPEED AND RPM when u take your foot off? are you a class a moron or what

incorrect!! have you ever driven down a steep hill with your foot off the gas? do you lose r's pm? I think not... you'll actually increase revs until you reach terminal velocity.

You are the king of open mouth, insert foot. Aren't you tired of being thought a fool yet?
I didnt just change the brand but went from 10W-40 to 5W-30 and from conventional oil to full synthetic.

No i got it to 60 and let off of the gas, and the car was at 3000 with the regular oil, and did the same with synthetic and it was 2500...on the same road i drive on every day. I think youre the moron now

Incorrect! It is dependent upon the weight of the vehicle, parasitic drag, road surface, compression ratio and selected gear ratio. You may have been above terminal velocity when you crested the hill and will in fact slow down.

omg, did u even read my whole post? look at hobos first, changing oil does not change your RPM, maybe ur engine is getting old and its rpm fluctuates, and letting go of the gas means no more gasoline is getting to your engine, hence no more power is produced and the friction and weight of the pistons will slow it down, letting go of the gas at 2500RPM dosent mean you will stay at 2500RPM till you hit the break, dip shit

10W-40 is thicker than 5W-30 and especially synthetic. 10W-40 WILL cause the rpm to be higher than 5W-30. Think, type, submit.

take your own advise, the same amount of oil is still put onto the inside of each cylinder, thicker oil means very little. OIL DOES NOT CHANGE RPM, esspecially by 500RPMs

to change from regular oil to synthetic do you have to do anything special other than drain all the oil out?

No matter how much you might wish this to be true, it is not. The viscosity difference between 5W-30 and 10W-40 will not change the engines RPM. More to the point, that still does not take into account that for a given road speed with given gearing, the RPM will always be the same no matter what weight oit the engine has in it.

Think, type, submit.

OR

Open mouth, insert foot.

Yes, you also need to change the filter, but... Changing to a synthetic oil may not be the best solution for your car depending on the engine's condition and various other factors.
