Which rear diff fluid??

What synthetic fluid do you recommend me for my 2003 Tacoma TRD 2wd also how many qtrs do I need?? I was thinking

$28 Mobil 75w 90 Synthetic Gear Lube - 1 Quart (Pack of 2)

Mobil 75w 90 or royal purple ??? Thanks in advance.

 

Mobil 1 cause it is available. Most places I can't get Redline or Royal Purple w/o having to order it.

 

I like Redline because it is a Type V synthetic, whereas Mobil is a type IV.

I believe Royal Purple is also a Type V.

 

Wrong.

 

I see. Would the

75w 90 meet specs for my 03 Tacoma??

One last quick question. Im using toyota type 4 for the transmission, ot should be any problem running synthetic on the rear diff correct??

 

redline 58304

75w-90 NON limited slip and you need EXACTLY 3 quarts. no more no less

 

Show me where it says Type V in that literature.

 

toyota type 4 is correct and you need 4-4.5 quarts. the manual is an error.

 

I may have caused some confusion, so I'll try to clarify;

GL vs Type.

GL-4 is for bronze syncos and other gearboxes with bronze.

GL-5 is for gearboxes without bronze. One of the friction modifiers in GL-5 will chemically attack bronze.


Type IV synthetic is a stabilized Dino oil the Mobil won the right to call synthetic by suing the FTC for the right to do so.


Type V is a truly synthetic ester formulated turbine oil. The demands of jet turbine bearings far exceed those of a gasoline piston engine.


So, back to the original question. I do not have a Taco manual in front of me so I can't answer the weight question, but I can answer a few others.

Don't run GL-5 in a tranny that specifies GL-4 or you will ruin it.

MOST differentials run GL-5.

Diff oil with the limited slip additive can be run in NON limited slip rear ends, and diff oil without the limited slip additive can be run in limited slip rear ends PROVIDED YOU INCLUDE THE FRICTION MODIFIER ADDITIVE.

 

Is that for the tranny or rear diff?

 

tranny. I used toyota type IV and about 4.25 quarts.
The rear diff I used redline 58304

I didn't know GL rating was different from "Type". News to me.

 

I understand. I'm always learning more about lubricants too.

It can get tough to cut through the marketing hype and internet rumors sometimes.
