differential fluid

Hey guys, thinking about changing my front and rear diff fluids. I wan wondering if there is any special 75-90 that the diff needed with the locking differential. Truck is a 2003 Tacoma extra cab 4x4 v6 supercharged TRD with 139,000 miles. Thanks!!

 

I use Mobil 1 synthetic

 

Well, use a quality diff fluid. Semi or full synthetic is nice. Also OEM isn't horrible.

75-90 will asuffice.

 

Amsoil Severe Gear 75W-90.

Don't forget to open the FILL plugs BEFORE you remove the drain plugs and replace the crush washers.

 

+2 for checking that the fill plugs will loosen before you drain the oil all out. DERP

Yeah id definietly go with a synthetic of some type

 

Is friction modifier required?

 

No.

 

That's what I thought.
Mobile1 syn, has LS additives in it, is that an issue?



BTW, dig the avatar Norton!

"Ralph as long we're neighbors don't call me Norton, call me Eduardo."

 

I'm not running Mobil 1, but I know others who are with no problems. IMO, that makes the answer to your question no issue running Mobil 1.

Thanks for your kind words! Some Honeymooners-related humor cracked a couple of us up in college and the nickname stuck (at least in certain circles)...
