Eyup. I've Google'd this topic to death and not found exact answer regarding mobil jet 2 oil. I want to fill, spin and drain before filling for good but to do this with acdelco or Eaton 'charger oil from eBay makes it a bit pricey to do this. I've looked on Mercedes-Benz forum and they have used mobil jet 2 oil in their Eatons. This is a cheaper option at around £15 a litre. Is anyone running this oil? Many thanks.

Me too. Think you need 1.5 bottles equivalent for the M62 SC, so you have to buy two..

Absolutely the wrong product for the job. I would not recommend and i'm very surprised Redline did. 

 

Closest oils to use are turbine oils, however £20-30 seems a small price to pay for a fill for life application.

Claim to be an expert do you?

 

Did you bother to email Redline!!!

 

If you had any knowledge of the Redline product or the original Eaton oil you would have noticed the specs are almost identical.  Turbine oils are synthetic ester based, so are Redline oils.

As Vocky stated, I design and formulate lubricants for a company which make up of approximately 1/3 of the worlds finished lubricant supply, including factory fill for the majority of European car manufacturers.

 

Not all Redline oils are ester based, in fact esters are used as a minority base stock component in the majority of oils that use them.

 

There are significant technical differences between power steering fluids and turbine type oils. Power steering oils are hydraulic fluids which undergo relatively low mechanical shear and gentle thermal cycles. They are designed with significant corrosion inhibitor and have little to no extreme pressure protection or oxidation protection.

 

In contrast, the supercharger oils require significant extreme pressure protection for the high speed and somewhat high load (due to supercharger inertia) of the gears. They also undergo significant thermal cycles and loading which means greater oxidation protection. Corrosion protection is much lower due to the lack of dissimilar materials in the supercharger housing. There are also different seals/polymer materials (coupler and casing seals) in the supercharger which a different fluid may not be compatible with.

 

Based on my experience with small volume oil marketers such as Redline, they have limited technical knowledge of the products they sell and will always try to fit a customers need to their product range. I would take their recommendation with a pinch of salt. They default to my company or the other three additive companies for technical detail when needed.

 

Bottom line. Power steering fluid is not suitable for supercharger applications. Expect sludge from oxidative degradation and gear pitting from continued use.

Thanks to all for the responses.  Great read from fezzasus and interesting.  Ive found spec for Mobil oil but cant find acdelco oil specification anywhere to compare it to.

I understand that the GM oil is the one recommended but just wanted to consider the alternative due to ability to fill and flush with some oil before filling for good (didn't want to cross-contaminate).  Plus Mobil tend to produce some pretty good oils.  Ultimately I don't want to scrap my 'charger so if GM is the way, so be it. 

 

Thanks again.

I'll just leave this here from Redline...
