I read through GM that the oil should not be changed/messed with on the m62?
is this not true?

 

yes it is considered a "sealed unit" which is good for 100k+ miles. But alot of people are running smaller pulleys than stock which are spinning the **** out of the blowers. So some feel it is good idea to change it.

I would just wait till the coupler gets noisey and change both at the same time.

I have changed mine before, and it was not needed. So i dont recommend it.

 

thanks!

 

I would reccommend changing it every 25k miles. You can order oil through zzp for like 10 bucks, and it takes 15 minutes to change. Take out the plug, drain, refill.

 

^seems excessive

 

its really not that excessive unless you put a ton of miles on your car. I usually put 25k on over a year and a half.

 

I have put 28k on my car since 07, original owner too lol

 

so whats once every 2+ years?

 

dude that is retarded its not needed till 100k or longer even if you run a 2.5 pully

 

Its not retarted. Ask ebristol. He changed his with 20k+ miles on it, ask him what it looked like. I was there. After seeing his, I changed mine.

 

lol its supposed to look like that

 

hey, do what you guys think is right for your cars. I'm just shooting out a reccomendation.

 

If you're stock or GM Stage 2, you don't really need to change it unless you service the blower (Coupler replacement...etc).

If you're using a small pulley, you should do a periodic change depending on how much you push the car.

 

if youre overspinning the blower i assume the oil is getting very hot and some of its properties will be lost alot faster that way. i dont know exactly when you should change it but 25k doesnt sound bad to me.
