I am going to be putting Motive 4.30 gears in this weekend with my mechanic friend.... and I was wondering what kind of rear diff oil I need... He said it should say on it if its synthetic or not, but I was wondering what is in there stock and what should I use.

Thanks.

 

Amsoil synthetic 75w140 in mine, I recommend the same.

You have to use a synthetic regardless of brand.

Thanks a lot!!

 

oh hey, 1 more question! About how much should I buy? he said I will need about 3 pints... is that right? I want to have everything ready.

 

You can use 3 pints if you want to short your differential and possibly burn something up.

The rear end found in the v6 equiped Mustang uses 3.2 pints

Your GT will need 4.2 pints. I went through about 2.5 quarts (5 pints) cause I didnt have a pump and I made a mess all over myself and the street.

Buy a fluid pump and save time and clean up.

+1 on the Amsoil 75w140, and I added little bottle of their friction modifier. Before this, my gears whined a little bit during low speed tight turns. Now, all is well.

And don't short fill your rear end. My Nissan Titan came from the factory short about a quart of axle oil. Rear end got so hot it melted all the paint off. Drained and filled it with Amsoil, never got hot again.

 

Thanks guys.

 

Redline Synthetic 75-140 differential oil, has the friction modifier already in it. Have used it in several vehicles, no problems.
It may cost a little more than Amsoil, but seems to perform better.
Redline also has a "heavy" shock proof oil for "hard" applications. aka racing.
check at www.redlineoil.com for product info and closest dealer.

 

Redline seems to be better how, have you used both oils in the same rearend?

Are you a lab technician of sorts?

Do you know what you are even posting?

I doesnt seem so by your choice of words....

ha

 

no offence TDS.... but I think I will go with the AMSOIL.... i have been following clevenand and his car, as well as hatchman and blazing saddles.... I read about it and it seems to be the stuff for me becuase it IS for heavy duty applications.

but thanks everybody!

 

dangit, nobody has the amsoil.... Who carries it? I tried Kragen and Napa....

 

No chain store will carry Amsoil, you can find it at some Speed Shops and Private Distributors.

Or....

I could resell some and ship a few bottles to ya.

I WANT IT FOR FRIDAY!!!! grrrrr.... i wish I had known.... ok, so if I cant find it, whats a good second that I can get at a major retailer.... vavoline?

 

mobil 1 I say from major retailers.

Where abouts in California are you? There are 2 dealers within 10 miles of my place (South of San Francisco).

Open that phone book of yours and call around to a few speed shops.

-Dan

 

I am just north of santa barbara.... I tried calling a few, and none carry it. I am willing to drive.... I have all day tomorrow, so I could go as far south as ventura or as far north as paso robles.... thats about at 200 miles stretch of California with me in the middle. I wish i knew earlier that I had to get it online.... but there MUST be a place close by.

Should I just get the Mobil 1? How much better is this amsoil? is it worth it? is this the Mobil 1 i should get? http://www.mobil1.com/USA-English/MotorOil..._75W-140LS.aspx

try it... those arent dealers like RETAILers... they are dealers if you are a store and want to carry amsoil products.

 

actually, that link will help you find a place in your area that will sell you Amsoil. It wont list every last shop though but its a start.
