Eaton M62 Oil fill amount Misconception

[Tom]

On many howto's for supercharging the 2.2/2.4 or even just the how to for replacing the oil in the m62 I have seen many people say you need 2 bottles of oil which is over 8oz's, this is wrong!...And all the arguing in the "how to change your M62 oil thread" just confused me more...SO straight from Eatons website here we are....Hopefully this will help clear the questions and misinformation..perhaps a sticky?

Please show me your data proving they die between 100-125k without an oil change. They are designed and tested for 150k miles and pass with flying colors.. How much oil do you think they loose on a 150k mile test? Never enter a battle of witts unarmed. :guns: This site has way to many people that like to spout thier wrong opinions as facts and mislead the unknowing..

Originally Posted by TVS_SS you need to fill it with 100ml or 3.4 oz from a completely drained state.. adding 2.5-3 oz would be typical for an oil plug drain because thats what you remove. You guys are just adding more "windage" frictional losses into your supercharger. It definately wont stop you from making boost.. but it will overheat your oil and push it past the seals DONT LISTEN TO THE PEOPLE TELLING YOU TO ADD MORE THAN THE AMOUNT I SPECIFIED. This is the exact reason i tell people to leave it alone, cause some people get it in their heads that "if some oil is good, more is better" If you add more, your only hurting yourself. Let me ask this question, what happens if you put 15 Quarts of oil in your cobalt vs. the 6 that it was designed for?

Originally Posted by TVS_SS it only gets 100ml (3.4oz) of oil from the factory... thats all it needs for 150,000 miles with no oil changes.. DO NOT FILL UP TO THE HOLE (this leads to very bad things) this type of misinformation is why i tell everyone to leave it alone!!!!!! If you recovered 3oz, that is exactly correct, you did not loose any oil

Also to fill it to the proper level you need to remove the SC and lay it flat on the bench, then fill it to the bottom of the hole, this will be around 3oz, just FYI.

Originally Posted by heartmycobalt I e-mailed eaton supercharger info and they told me 3.4-3.5oz. I am going to stick to this; many of you have put 6 oz. in and maybe its working fine for you and thats great, but the rep told me 3.4oz. so thats what i'll put in.
