Sorry guys I know this has been asked 1000 times and I searched and searched and searched but came up with nothing. Anyway, I have three questions.

1) Should I use Royal Purple 75W90 Max Gear oil? If so, how many bottles? 2?

2) On Royal Purples website it says that it already has additives for the clutches, etc. Should I buy a bottle of FRPP friction modifier anyway? RP says no but I have heard yes. Whats your opinion?

3) I am also going to be putting on a rear end cover at the same time. I also have a MM panhard bar waiting to be installed. MM says that there may be clearance issues with some covers... does anyone know of a company that makes low profile covers? Or just anything that will fit specifically with the MM panhard bar?

 

I used a little over two bottles and no u dont need any modifier its mix in.

 

So do you think I should buy three bottles or just buy two? I dont want to have them run out of fluid.

 

buy 3, i just had to refill my diff and it took a little over 2... 2 wont cut it, get 3 to be safe.

 

I would get three. Better safe then sorry.

 

OK. Sounds good. So question one is definetly answered. What about two and three? Whats everyone elses take on the friction modifier? I think I might just go without it like suggested above.

 

The gearmax bottle says it includes modifier.

 

I am pretty sure all synthetics have the modifier..you only have to add when you use regular oil.

 

OK. Thats solved. I am picking up three bottles of RP 75 90 gear oil tomorrow morning.

Does anyone know about the panhard bar situation? I really want to order the girdle cover tomorrow morning. The faster I get it the sooner I can get my car into the shop to get these biatches installed.

 

I don't know about fitment for you, but I have a Mac girdle and like it a lot.
