Doing a trans/diff fluid change, are these oil good?
 

Hello,


I'm dong my trans/diff fluid soon and I'm getting amsoil.
2x https://www.amsoil.com/p/severe-gear...?code=SVGPK-EA
for my diff


2x https://www.amsoil.com/p/manual-tran...?code=MTGPK-EA
for my trans



I just want to make sure these are compatible with the f86 platform and I'm good to go to buy these

Trans and diff can use the same oil. 75W-90 is more than okay, brand is up to your choice. AMSOIL is pricey, but they make quality products.

Some thing wrong with factory fill?

Factory fill tends to keep the trans feeling notchy. Doing your LSD at the same time is just good practice and maintenance even though the manual states a "Check" at 30K miles.

Switching to Motul, Amsoil, or Redline improves the feel and quality of both fluids.

I switched them maybe 2 weeks after getting my BRZ with 13K miles and the difference when switching gears was improved compared with the factory fill.

Nope. The factory fill has worked just fine in my 2013 FRS for the last 9 years.

:thumbsup:

You probably will need 3 quarts for the transmission.

Edit: Damnit I necro-ed...

The bolded statement is a matter of contention. Yes it will function, but I think there are differences between the products listed. I forget what they are though lol.

I think for daily use, Motul 75W-90 should be more than okay. For other applications, I would recommend using a more refined product.

I really didn't care for the motul trans oil and ditched it after a short time. I have been running redline MT-90 since I can get it anywhere, shifts nicer, and is a bit cheaper. I know other guys swear by Synchromesh for the same reasons.

I'd have to check it out. I haven't really changed it since I got the vehicle with 13K Miles. It was an improvement from the OEM one and haven't had any issues ever since. I got about 5K miles until I change it again and I'll go with either Amsoil or Redline.



My biggest grudge was a feeling of lack of leverage when shifting gears, which the Raceseng weighted knob took care off like a champ.

+1 on the Raceseng shift knob. Probably, dollar for dollar, the best single mod I’ve made to mine.
