What do guys think about this stuff? The website makes out it can add BHP which im alittle sceptical about... Just wondering what sort of quality people think this is?

Might be here?

 

Lol, sounds almost too good to be true doesnt it? What sort of grades / quantities should i be looking at for the diff / auto box ?

 

Thanks all...

Don't know about Auto but Manual is 4 litres for the gear box and 3 litres for the diff.

Thanks mate, so 3 litres for the diff, but anyone give me an idea whats needed for an auto box?

think it's 7 litres but could be wrong

Well you know what I think!!! It's good shit!!! :bow: Z seems to be getting even better and better as the week has gone on now it has lubed itself all over the the engine, gearbox and transmission components...

 

One big thing i've noticed as well as the power difference is when you used to coast up to a junction in gear or just completely take your foot off the throttle in gear - the car would slow down or loose speed quiet considderably i.e you used to get the feeling of dragg... Now with the Royal Purple Oils in when you coast in gear it feels as if you've taken your car out of gear and are just free wheeling i.e no engine braking!!!! :x:

 

Think I might have to upgrade my brakes now due to the lack of engine braking i've lost!!! :rofl: :D

Three litres for the diff ? That sounds a helluva lot ...

Bit less the manual reckons :-

I only put that because when I bought my diif oil I need 3 bottles at a litre per bottle as they where not willing to split a bottle to give me the correct amount. LMAO

Chip Foose ( :bow: ) uses Royal Purple too, so it can't be bad.

Sounds good to me, what grades do i need for the gearbox and diff then? Also any advance on 7litres for an auto box?

Any advance on grades / gearbox quantity guys?

This sound right for the diff?

 

API GL 5 specification, viscosity SAE 80W-90 (taken from american How to..)?

 

Still looking for the gearbox details...

 

 

Edit royalpurple only do diff oil meeting gl-5 in the following: 75w90 , 75w140 and 85w140. Guessing 75w90 the way forward?

 

 

Edit: just noticed 80w90 available in cases, this the right stuff?
